Prediction of wax buildup in 24 inch cold, deep sea oil loading line  

SciTech Connect (OSTI)

When designing pipelines for cold environments, it is important to know how to predict potential problems due to wax deposition on the pipeline's inner surface. The goal of this work was to determine the rate of wax buildup and the maximum, equlibrium wax thickness for a North Sea field loading line. The experimental techniques and results used to evaluate the waxing potential of the crude oil (B) are described. Also, the theoretic model which was used for predicting the maximum wax deposit thickness in the crude oil (B) loading pipeline at controlled temperatures of 40 F (4.4 C) and 100 F (38 C), is illustrated. Included is a recommendation of a procedure for using hot oil at the end of a tanker loading period in order to dewax the crude oil (B) line. This technique would give maximum heating of the pipeline and should be followed by shutting the hot oil into the pipeline at the end of the loading cycle which will provide a hot oil soaking to help soften existing wax. 14 references.

Studies of the Kuwait oil fire plume during midsummer 1991  

SciTech Connect (OSTI)

This paper reports aircraft observations of the Kuwait oil fire plume conducted during the period July 31-August 17, 1991. During this study the plume was transported almost exclusively to the south of Kuwait over the Persian Gulf and the Arabian Peninsula. The plume base was generally found to be well above the surface, in some cases as high as 1-2 km; plume tops did not exceed 5 km. Aerosol mass (based on measured aerosol constituents) in the central section of the plume, ca. 150-200 km downwind of the source region, was found to be >500 {mu}g/m{sup 3}, with number densities in the size range (approximate) 0.2 < d < 3 {mu}m (where d is diameter) as high as 30,000/cm{sup 3}. The aerosol was composed of (in order of approximate contribution to mass) inorganic salts, elemental carbon, and organic carbon. Sodium chloride constituted a surprisingly large component of the soluble inorganic mass. The aerosol particles appeared to function as good cloud condensation nuclei, with a large fraction of accumulation mode particles (by number) activated at a supersaturation of 0.6%. Under conditions in which the plume was relatively compact, transmittance of solar radiation to the surface was only 10-20%. Plume albedo was observed to be as low as 2-3% close to the source region, consistent with the high elemental-carbon concentrations present in the plume. Trace gas concentrations were consistent with fuel composition and with current knowledge of atmospheric chemical processes. Sulfur dioxide concentrations close to the source region were found to be as high as 300-400 ppb. The emissions factor for S (expressed as a percentage) was estimated to be 1.8%, which is consistent with estimates of a fuel sulfur content of 2-2.5%. SO{sub 2} was found to be only slowly oxidized (<1%/h). Nitrogen oxide concentrations were found to be quite low (<50 ppb near the source, decreasing to 1-2 ppb well downwind), which is consistent with a crude oil nitrogen source. 32 refs., 15 figs., 7 tabs.

Trace gas measurements in the Kuwait oil fire smoke plume  

SciTech Connect (OSTI)

The authors report trace gas measurements made both inside and outside the Kuwait oil-fire smoke plume during a flight of an instrumented research aircraft on May 30, 1991. Concentrations of SO{sub 2}, CO, and NO{sub x} averaged vertically and horizontally throughout the plume 80 km downwind of Kuwait City were 106, 127, and 9.1 parts per billion by volume (ppbv), respectively, above background concentrations. With the exception of SO{sub 2}, trace gas concentrations were far below typical US urban levels and primary national ambient air quality standards. Ambient ozone was titrated by NO in the dark, dense core of the smoke plume close to the fires, and photochemical ozone production was limited to the diffuse edge of the plume. Photochemical O{sub 3} production was noted throughout the plume at a distance of 160 km downwind of Kuwait City, and averaged 2.3 ppbv per hour during the first 3 hours of transport. Little additional photochemical production was noted at a downwind range of 340 km. The fluxes of sulfur dioxide, carbon monoxide, and reactive nitrogen from the roughly 520 fires still burning on May 30, 1991 are estimated at 1.4 x 10{sup 7} kg SO{sub 2}/d, 6.9 x 10{sup 6} kg CO/d, and 2.7 x 10{sup 5} kg N/d, respectively. Generally low concentrations of CO and NO{sub x} indicate that the combustion was efficient and occurred at low temperatures. Low total nonmethane hydrocarbon concentrations suggest that the volatile components of the petroleum were burned efficiently. 37 refs., 4 figs., 4 tabs.

Measurement of polynuclear aromatic hydrocarbon concentrations in the plume of Kuwait oil well fires  

SciTech Connect (OSTI)

Following their retreat from Kuwait during February and March of 1991, the Iraqi Army set fire to over 500 oil wells dispersed throughout the Kuwait oil fields. During the period of sampling from July to August 1991, it was estimated that between 3.29 {times} 10{sup 6} barrels per day of crude oil were combusted. The resulting fires produced several plumes of black and white smoke that coalesced to form a composite ``super`` plume. Because these fires were uncontrolled, significant quantities of organic materials were dispersed into the atmosphere and drifted throughout the Middle East. The organic particulants associated with the plume of the oil well fires had a potential to be rich in polynuclear aromatic hydrocarbon (PAH) compounds. Based on the extreme mutagenic and carcinogenic activities of PAHs found in laboratory testing, a serious health threat to the population of that region potentially existed. Furthermore, the Kuwait oil fire plumes represented a unique opportunity to study the atmospheric chemistry associated with PAHs in the plume. If samples were collected near the plume source and from the plume many kilometers downwind from the source, comparisons could be made to better understand atmospheric reactions associated with particle-bound and gas-phase PAHs. To help answer health-related concerns and to better understand the fate and transport of PAHs in an atmospheric environment, a sampling and analysis program was developed.

High opacity white plumes from coal-fired and oil-fired sources  

SciTech Connect (OSTI)

In recent years, with the installation of high efficiency particulate emission control devices on utility and industrial boilers, high-opacity white plumes have become more of a problem because formerly the emissions of primary particulate matter obscured and/or served as a condensing surface for the condensable material. The problem common to some of these installations is the violation of opacity standards due to the presence of a high-opacity persistent plume that emits from the stack. Oil fired boilers violating opacity standards typically comply with mass emission standards while coal fired boilers typically violate visual emission standards when simultaneously violating mass emission standards. The investigation reported here focuses on the atypical case when in-situ transmissometer measurements show compliance but plume opacity as measured by Reference Method 9 or LIDAR exceeds opacity standards. This case comes about due to gas phase reactions that produce fine aerosols, vapor phase condensation and physical agglomeration of sub-micron sized clusters and particles. The plume opacity control technology applicable to these aerosols which are created and/or grown in white plume is discussed in this paper.

Daily dispersion model calculations of the Kuwait oil fire smoke plume  

SciTech Connect (OSTI)

The Atmospheric Release Advisory Capability (ARAC) provided daily forecasts of the position and spatial character of the Kuwait oil fire smoke plume to the NSF-coordinated research aircraft missions in the Persian Gulf. ARAC also provided daily plume dispersion products to various nations in the Persian Gulf region under the auspices of the World Meteorological Organization for a period of nearly 5 months. Forecasted three dimensional winds were provided to ARAC from the US Air Force Global Weather Central`s Relocatable Wind Model (RWM). The RWM winds were spaced approximately 90 km in the horizontal and were located at the surface, 1000 ft., 2000 ft, 5000 ft and every 5000 ft up to 30,000 ft elevation. The forecast periods were 0, 6, 24, and 36 hours from both 0000 and 1200 UTC. A wind field model (MATHEW) corrected for terrain influences on the wind. The smoke plume was dispersed using a three dimensional particle-in-cell code (ADPIC) with buoyant plume rise capability. Multiple source locations were used to represent the burning oil fields. Improved estimates of the source term and emission factors for the smoke were incorporated into the ADPIC calculations as the field measurement data were made available.

Chapter Three - The Study of Deep-Sea Cephalopods  

Science Journals Connector (OSTI)

Abstract Deep-sea cephalopods are here defined as cephalopods that spend a significant part of their life cycles outside the euphotic zone. In this chapter, the state of knowledge in several aspects of deep-sea cephalopod research are summarized, including information sources for these animals, diversity and general biogeography and life cycles, including reproduction. Recommendations are made for addressing some of the remaining knowledge deficiencies using a variety of traditional and more recently developed methods. The types of oceanic gear that are suitable for collecting cephalopod specimens and images are reviewed. Many groups of deep-sea cephalopods require taxonomic reviews, ideally based on both morphological and molecular characters. Museum collections play a vital role in these revisions, and novel (molecular) techniques may facilitate new use of old museum specimens. Fundamental life-cycle parameters remain unknown for many species; techniques developed for neritic species that could potentially be applied to deep-sea cephalopods are discussed. Reproductive tactics and strategies in deep-sea cephalopods are very diverse and call for comparative evolutionary and experimental studies, but even in the twenty-first century, mature individuals are still unknown for many species. New insights into diet and trophic position have begun to reveal a more diverse range of feeding strategies than the typically voracious predatory lifestyle known for many cephalopods. Regular standardized deep-sea cephalopod surveys are necessary to provide insight into temporal changes in oceanic cephalopod populations and to forecast, verify and monitor the impacts of global marine changes and human impacts on these populations.

Sulfate formation in oil-fired power plant plumes. Volume 1. Parameters affecting primary sulfate emissions and a model for predicting emissions and plume opacity. Final report  

SciTech Connect (OSTI)

High sulfuric acid emissions with concomitant acid smuts and plume opacity concerns at oil fired utility boilers has been associated with combustion of high sulfur-, high vanadium-containing fuel. The purpose of this program was to elucidate the mechanisms responsible for the formation of flue gas H/sub 2/SO/sub 4/ and metal sulfates (MSO/sub 4/) and to determine the extent by which operating and controls parameters as well as the composition of the fuel affected those emissions. More than 200 flue gas measurements were made at a number of oil fired units and one coal fired unit, providing emissions levels of SO/sub 2/, H/sub 2/SO/sub 4/, MSO/sub 4/, total suspended particulate, and NO/sub x/. Parameters shown to significantly affect H/sub 2/SO/sub 4/ and MSO/sub 4/ emissions were furnace O/sub 2/ level, sulfur and vanadium content of the fuel, the amount of corrosion inhibitor added to the oil, power level, and the composition of the fly ash. Correlations were developed which related the H/sub 2/SO/sub 4/ and MSO/sub 4/ emissions at oil fired units with the parameters above; predictions of emissions appear to be accurate to within +-25%. Based on limited data from the literature, the correlations were extended to include a means for predicting plume opacity and in-stack opacity. Recommendations for controlling the levels of H/sub 2/SO/sub 4/ and MSO/sub 4/ emissions as well as maintaining utility units in compliance with opacity regulations were made. Future research needs were indicated, including more studies relating H/sub 2/SO/sub 4/ levels in flue gas with plume opacity and emissions studies at coal fired units. 85 references, 27 figures, 23 tables.

Why Sequence Thermoacidophiles of deep-sea hydrothermal vents?  

Broader source: All U.S. Department of Energy (DOE) Office Webpages (Extended Search)

Thermoacidophiles of Thermoacidophiles of deep-sea hydrothermal vents? Bacteria that live in hydrothermal vents on land and deep underwater need to be able to tolerate high temperatures and harsh, nutrient-poor environments with high concentrations of metals. As a result of living in such environments, however, these bacteria have enzymes that are stable at high temperatures, which could be useful for producing alternative fuels. Thermoacidophiles Photo: University of Delaware Aquificales bacteria are often found in thermal streams and associated with sulfide precipitation. Sequencing some of these bacterial genomes -- specifically, Thermocrinis ruber, S. rodmanii and S. kristjansonnii -- could provide researchers with so-called "anchor genomes" that would be applied in turn to studies already being done on microbial communities in

Twenty thousand sterling under the sea: Estimating the value of protecting deep-sea biodiversity  

Science Journals Connector (OSTI)

Abstract The deep-sea includes over 90% of the world's oceans and is thought to be one of the most diverse ecosystems in the world. It supplies society with valuable ecosystem services, including the provision of food, the regeneration of nutrients and the sequestration of carbon. Technological advancements in the second half of the 20th century made large-scale exploitation of mineral, hydrocarbon and fish resources possible. These economic activities, combined with climate change impacts, constitute a considerable threat to deep-sea biodiversity. Many governments, including that of the UK, have therefore decided to implement additional protected areas in their waters of national jurisdiction. To support the decision process and to improve our understanding for the acceptance of marine conservation plans across the general public, a choice experiment survey asked Scottish households for their willingness-to-pay for additional marine protected areas in the Scottish deep-sea. This study is one of the first to use valuation methodologies to investigate public preferences for the protection of deep-sea ecosystems. The experiment focused on the elicitation of economic values for two aspects of marine biodiversity: (i) the existence value for deep-sea species and (ii) the option value of deep-sea organisms as a source for future medicinal products.

Preserving deep-sea natural heritage: Emerging issues in offshore conservation and management  

Science Journals Connector (OSTI)

Human activity in the deep sea is extending ever deeper, with recent research showing that this environment is more sensitive to human and natural impacts than previously thought. Some deep-water fish stocks have collapsed and fishing methods such as bottom trawling have raised international concern over the habitat damage they cause. It is likely that in its current form, deep-sea fishing is unsustainable. Diminishing reserves of hydrocarbons in shallow water are pushing exploration and production into deeper waters, which may cause damage to little known deep-sea habitats. The deep sea is also proposed as an environment where anthropogenic carbon dioxide could be stored to minimise the effect of its release into the atmosphere. At the same time, rising atmospheric carbon dioxide levels may be altering the chemical equilibrium of the global ocean by lowering pH. Many countries are now beginning to designate some deep-sea habitats as marine protected areas in measures to reduce the damage caused by fishing and other anthropogenic activities. This review examines these current and emerging issues in deep-sea conservation and discusses conservation status and the designation of protected areas. The enforcement of protected areas using satellite tracking of vessels is discussed and applied to an internationally agreed deep-water conservation area, which aims to protect cold-water coral habitats on the Darwin Mounds in the north east Atlantic Ocean.

Smoke plumes from Kuwaiti oil fires as atmospheric experiment of opportunity: An early look. Final report, Mar-Oct 91  

SciTech Connect (OSTI)

This document sets in context the smoke plume phenomenology associated with the large number of oil fires lit by the Iraqi military in Kuwait in February 1991, and which are probably the worst man-made air pollution event in human history. Based on the simple phenomenology given here, and considered an unfortunate 'experiment of opportunity', the question is raised of what actions should be taken, and what one can hope to learn from these events. From the standpoint of SDIO, most of the basic physical elements of the fire and smoke phenomenology appear to be understood although there are some new effects and the initial quantitative predictions of the experts appear to differ significantly from the results of the detailed measurements. Many observations have been made. They require analysis followed by review and publication before being incorporated in the DoD integrated phenomenology models. This document represents an early look at the smoke plumes before most of the observations have been analyzed, reviewed, and published; its main function is to raise questions that should be addressed more carefully later.

Geological overview of the Angola-Congo Margin, the Congo deep-sea fan and its submarine valleys  

E-Print Network [OSTI]

The Congo deep-sea fan is one of the largest fans in the world still affected by presently active turbidity currents. The present activity of deep-sea sedimentary processes is linked to the existence of a direct connection between the Congo River estuary and the Congo canyon head that allows relatively continuous sediment feeding of the deep-sea environment, in spite of a wide continental shelf (150 km). Because of this important activity in terms of sedimentary processes, the deep-sea environment of the Congo-Angola margin presents major interests concerning physical, chemical and biological studies near the sea floor. The main aim of this paper is to present the initial geological context of the BioZaire Program, showing a synthesis of the major results of the ZaAngo Project including (1) the brief geological setting of the Congo-Angola margin, (2) the structure of the modern Congo deep-sea fan, (3) the sedimentary architecture of the recent Congo turbidite system (from the canyon to the distal lobes), and (4) the recent and present turbidite sedimentation. In order to provide useful information and advice relevant to biological and geochemical studies across the Congo sedimentary system, this article focuses on the present sedimentary processes and the present activity of turbidity current along the Congo canyon and channel.

Offshore Floating Wind Turbine-driven Deep Sea Water Pumping for Combined Electrical Power and District Cooling  

Science Journals Connector (OSTI)

A new concept utilising floating wind turbines to exploit the low temperatures of deep sea water for space cooling in buildings is presented. The approach is based on offshore hydraulic wind turbines pumping pressurised deep sea water to a centralised plant consisting of a hydro-electric power system coupled to a large-scale sea water-cooled air conditioning (AC) unit of an urban district cooling network. In order to investigate the potential advantages of this new concept over conventional technologies, a simplified model for performance simulation of a vapour compression AC unit was applied independently to three different systems, with the AC unit operating with (1) a constant flow of sea surface water, (2) a constant flow of sea water consisting of a mixture of surface sea water and deep sea water delivered by a single offshore hydraulic wind turbine and (3) an intermittent flow of deep sea water pumped by a single offshore hydraulic wind turbine. The analysis was based on one year of wind and ambient temperature data for the Central Mediterranean that is known for its deep waters, warm climate and relatively low wind speeds. The study confirmed that while the present concept is less efficient than conventional turbines utilising grid-connected electrical generators, a significant portion of the losses associated with the hydraulic transmission through the pipeline are offset by the extraction of cool deep sea water which reduces the electricity consumption of urban air-conditioning units.

AMS measurements of cosmogenic and supernova-ejected radionuclides in deep-sea sediment cores  

E-Print Network [OSTI]

Samples of two deep-sea sediment cores from the Indian Ocean are analyzed with accelerator mass spectrometry (AMS) to search for traces of recent supernova activity around 2 Myr ago. Here, long-lived radionuclides, which are synthesized in massive stars and ejected in supernova explosions, namely 26Al, 53Mn and 60Fe, are extracted from the sediment samples. The cosmogenic isotope 10Be, which is mainly produced in the Earths atmosphere, is analyzed for dating purposes of the marine sediment cores. The first AMS measurement results for 10Be and 26Al are presented, which represent for the first time a detailed study in the time period of 1.7-3.1 Myr with high time resolution. Our first results do not support a significant extraterrestrial signal of 26Al above terrestrial background. However, there is evidence that, like 10Be, 26Al might be a valuable isotope for dating of deep-sea sediment cores for the past few million years.

Yttrium and rare earth elements in fluids from various deep-sea hydrothermal systems  

SciTech Connect (OSTI)

Rare earth element (REE) and yttrium (Y) concentrations were measured in fluids collected from deep-sea hydrothermal systems including the Mid-Atlantic Ridge (MAR), i.e., Menez Gwen, Lucky Strike, TAG, and Snakepit; the East Pacific Rise (EPR), i.e., 13{degree}N and 17--19{degree}S; and the Lau (Vai Lili) and Manus (Vienna Woods, PacManus, Desmos) Back-arc Basins (BAB) in the South-West Pacific. In most fluids, Y is trivalent and behaves like Ho. Chondrite normalized Y-REE (Y-REE{sub N}) concentrations of fluids from MAR, EPR, and two BAB sites, i.e., Vai Lili and Vienna Woods, showed common patterns with LREE enrichment and positive Eu anomalies. REE analysis of plagioclase collected at Lucky Strike strengthens the idea that fluid REE contents, are controlled by plagioclase phenocrysts. Other processes, however, such as REE complexation by ligands (Cl{sup {minus}}, F{sup {minus}}, So{sub 4}{sup 2{minus}}), secondary phase precipitation, and phase separation modify REE distributions in deep-sea hydrothermal fluids. REE speciation calculations suggest that aqueous REE are mainly complexed by Cl{sup {minus}} ions in hot acidic fluids from deep-sea hydrothermal systems. REE concentrations in the fluid phases are, therefore, influenced by temperature, pH, and duration of rock-fluid interaction. Unusual Y-REE{sub N} patterns found in the PacManus fluids are characterized by depleted LREE and a positive Eu anomaly. The Demos fluid sample shows a flat Y-REE{sub N} pattern, which increases regularly from LREE to HREE with no Eu anomaly. These Manus Basin fluids also have an unusual major element chemistry with relatively high Mg, So{sub 4}, H{sub 2}S, and F contents, which may be due to the incorporation of magmatic fluids into heated seawater during hydrothermal circulation. REE distribution in PacManus fluids may stem from a subseafloor barite precipitation and the REE in Demos fluids are likely influenced by the presence of sulfate ions.

Transport of terrestrial organic matter in the Ogoou deep sea turbidite system (Gabon)  

Science Journals Connector (OSTI)

In order to define the nature and distribution of the organic matter (OM) preserved in the modern Ogoou deep sea turbidite system (Gabon), bulk geochemical techniques (Rock-Eval pyrolysis, elemental and isotopic analyses) and palynofacies were applied to three piston cores collected in the Cape Lopez Canyon and lobe and on the continental slope, north of the canyon. The hemipelagic sedimentation in the study area is characterized by high accumulations of well-preserved OM (?23wt. TOC %). Bulk geochemical and palynofacies analysis indicate both a marine and terrestrial origin of the OM. Contribution of the marine source is higher on the slope than in the canyon and lobe. OM accumulation in turbidites is strongly controlled by the combined influence of the Cape Lopez Canyon and littoral drift. In the canyon and lobe, turbidites show generally low TOC content (0.5wt. %) and OM is oxidized. The origin of the OM is interpreted as both marine and terrestrial, with a higher contribution of continental source versus marine source. The low TOC contents are due to the large siliciclastic fraction transported by the littoral drift and diverted in the Cape Lopez Canyon during high energy processes (e.g. storms) which tend to dilute the OM in the turbidites. Transport by long-shore currents and/or turbiditic flows leads to oxidation of the OM. On the continental slope located north of the Cape Lopez Canyon, large amounts of OM are deposited in turbidites (up to 14wt. %). The OM is predominantly derived from terrestrial land plants and has not been subjected to intense oxidation. These deposits are characterized by high hydrocarbon potential (up to 27kg HC/t rock), indicating a good potential as gas-prone source rock. Because Cape Lopez Canyon captures a significant part of the sediment transported by the littoral drift, the siliciclastic sedimentary flux is reduced north of the canyon; OM is thus concentrated in the turbidites. Variation in TOC content within turbidite laminae can be explained by the burst and sweep deposition process affecting the boundary layer of the turbulent flow. This study confirms that gravity flows play a preponderant role in the accumulation and preservation of OM in deep water and that deep sea turbidite systems could be regarded as an environment where organic sedimentation occurs.

An evaluation of deep-sea benthic megafauna length measurements obtained with laser and stereo camera methods  

Science Journals Connector (OSTI)

Abstract The 25 year time-series collected at Station M, ~4000m on the Monterey Deep-sea Fan, has substantially improved understanding of the role of the deep-ocean benthic environment in the global carbon cycle. However, the role of deep-ocean benthic megafauna in carbon bioturbation, remineralization and sequestration is relatively unknown. It is important to gather both accurate and precise measurements of megafaunal community abundance, size distribution and biomass to further define their role in deep-sea carbon cycling and possible sequestration. This study describes initial results from a stereo camera system attached to a remotely operated vehicle and analyzed using the EventMeasure photogrammetric measurement software to estimate the density, length and biomass of 10 species of mobile epibenthic megafauna. Stereo length estimates were compared to those from a single video camera system equipped with sizing lasers and analyzed using the Monterey Bay Aquarium Research Institutes Video Annotation and Reference System. Both camera systems and software were capable of high measurement accuracy and precision (<1mm measurement error and precision). However, the oblique angle of the single video camera caused the spatial scale of the image perspective to change with distance from the camera, resulting in error when measurements were not parallel or vertical to two horizontal-oriented scaling lasers. Analysis showed that the stereo system recorded longer lengths and higher biomass estimates than the single video camera system for the majority of the 10 megafauna species studied. The stereo image analysis process took substantially longer than the video analysis and the value of the EventMeasure software tool would be improved with developments in analysis automation. The stereo system is less influenced by object orientation and height, and is potentially a useful tool to be mounted on an autonomous underwater vehicle and for measuring deep-sea pelagic animals where the use of lasers is not feasible.

Preservation of Fe(II) by Carbon-Rich Matrices in Hydrothermal Plumes Print Preservation of Fe(II) by Carbon-Rich Matrices in Hydrothermal Plumes Print Despite the considerable amount of iron that enters the oceans from the continents and from hydrothermal vents at mid-ocean ridges on the seafloor, there are large regions of the global ocean where iron availability is so low that it limits life. Oceanographers have long explained this anomaly by assuming that the iron in the sea is primarily incorporated as Fe(III) into inorganic minerals that lack both the mobility to circulate over long distance and bioavailability to sea life as an essential nutrient. Now, a collaboration led by researchers from the Woods Hole Oceanographic Institution has reported that the hydrothermal plumes emerging from the vents actually contain iron in both Fe(II) and Fe(III) oxidation states associated with organic material from nearby flora and fauna. The collaboration suggests that the organic matrices prevent oxidation and precipitation of the Fe(II), perhaps increasing both its circulation through the world's oceans and its bioavailability as a deep-sea nutrient.

Complete genome sequence of the aerobic, heterotroph Marinithermus hydrothermalis type strain (T1T) from a deep-sea hydrothermal vent chimney  

SciTech Connect (OSTI)

Marinithermus hydrothermalis Sako et al. 2003 is the type species of the monotypic genus Marinithermus. M. hydrothermalis T1 T was the first isolate within the phylum ThermusDeinococcus to exhibit optimal growth under a salinity equivalent to that of sea water and to have an absolute requirement for NaCl for growth. M. hydrothermalis T1 T is of interest because it may provide a new insight into the ecological significance of the aerobic, thermophilic decomposers in the circulation of organic compounds in deep-sea hydrothermal vent ecosystems. This is the first completed genome sequence of a member of the genus Marinithermus and the seventh sequence from the family Thermaceae. Here we describe the features of this organism, together with the complete genome sequence and annotation. The 2,269,167 bp long genome with its 2,251 protein-coding and 59 RNA genes is a part of the Genomic Encyclopedia of Bacteria and Archaea project.

Thermovibrio ammonificans type strain HB-1T is a thermophilic (Topt: 75 C), strictly anaero- bic, chemolithoautotrophic bacterium that was isolated from an active, high temperature deep-sea hydrothermal vent on the East Pacific Rise. This organism grows on mineral salts medium in the presence of CO2/H2, using NO3- or S0 as electron acceptors, which are re- duced to ammonium or hydrogen sulfide, respectively. T. ammonificans is one of only three species within the genus Thermovibrio, a member of the family Desulfurobacteriaceae, and it forms a deep branch within the phylum Aquificae. Here we report the main features of the genome of T. ammonificans strain HB-1T (DSM 15698T).

Effects of Carbon Dioxide Hydrate Emplacement on Deep-Sea Foraminiferal Assemblages Abstract #1340h b33-1020  

SciTech Connect (OSTI)

ABSTRACT Two studies, conducted in cooperation with the Monterey Bay Aquarium Research Institute (using the R/V Western Flyer and the ROV Tiburon), investigated effects of carbon dioxide hydrate emplacement and associated dissolution products on foraminifera at two sites (3600m and 3100m) off the California margin. Foraminifera are ideal for these investigations because of differing test composition (calcareous and agglutinated) and thicknesses, and diverse epifaunal and infaunal depth preferences. The pH of each site was monitored by Seabird CTDs. Suites of sediment push-cores were collected and stained (to distinguish live from dead). These included control cores and multiple experimental core types (corral, distal, and proximal). Core length differed between the two studies in part to assess the effective depth of penetration of CO2 within the sediments. Effects of CO2 emplacement on foraminiferal assemblages have been tracked both vertically (10-20cm below the sea floor) and horizontally (up to 50m from CO2 injection sites), and between live and dead individuals. Results from these experiments are in accordance on several major effects: 1) increased mortality and dissolution as a consequence of CO2 hydrate exposure; 2) total number of foraminifera in the sample decreases; and 3) resistance to dissolution varies with depth and species. Down-core trends (to 10cm bsf) for the 3600m study show: 1) an exponential decrease of tests with depths; 2) percent agglutinated forms decline and calcareous forms increasingly dominate with depth; 3) agglutinated diversity decreases with depth; and 3) assemblages in experimental cores become increasingly similar with depth to those in control cores. Down-core trends for the 3100m study show: 1) a uniform distribution of tests to a depth of 14cm; 2) below 14cm there is a linear increase in test abundance per centimeter; and 3) deep penetration of carbonate dissolution (up to 16cm) in assemblages in experimental cores. These results suggest that while the overall effects of mortality and dissolution of foraminifera are similar, emplacement effects vary between sites, with shallower assemblages better demonstrating the true magnitude due to the predominantly calcareous forms. Both sites experienced a small overall reduction in ocean pH as well as large excursions resulting from CO2 injection. Exposure to this low pH plume caused increased mortality and dissolution of calcareous foraminifera as far as 50m from the injection site. These results imply almost complete initial mortality and dissolution upon CO2 hydrate emplacement in the corrals.

Preservation of iron(II) by carbon-rich matrices in a hydrothermal plume  

SciTech Connect (OSTI)

Hydrothermal venting associated with mid-ocean ridge volcanism is globally widespread. This venting is responsible for a dissolved iron flux to the ocean that is approximately equal to that associated with continental riverine runoff. For hydrothermal fluxes, it has long been assumed that most of the iron entering the oceans is precipitated in inorganic forms. However, the possibility of globally significant fluxes of iron escaping these mass precipitation events and entering open-ocean cycles is now being debated, and two recent studies suggest that dissolved organic ligands might influence the fate of hydrothermally vented metals. Here we present spectromicroscopic measurements of iron and carbon in hydrothermal plume particles at the East Pacific Rise mid-ocean ridge. We show that organic carbon-rich matrices, containing evenly dispersed iron(II)-rich materials, are pervasive in hydrothermal plume particles. The absence of discrete iron(II) particles suggests that the carbon and iron associate through sorption or complexation. We suggest that these carbon matrices stabilize iron(II) released from hydrothermal vents in the region, preventing its oxidation and/or precipitation as insoluble minerals. Our findings have implications for deep-sea biogeochemical cycling of iron, a widely recognized limiting nutrient in the oceans.

The present study reports on the bio-organic composition of a deep-sea venting hydrothermal system originating from arc volcanism; the origin of the particulates in hydrothermal fluids from the Suiyo Seamount in the southern Izu-Bonin (Ogasawara) Arc is discussed with regard to amino compounds. Chimney samples on deep-sea hydrothermal systems and core samples at Suiyo Seamount were determined for amino acids, and occasionally amino sugars. Two types of chimney samples were obtained from active hydrothermal systems by submersible vehicles: one was natural chimney (NC) on a hydrothermal natural vent; the other was artificial chimneys (AC), mainly formed by the growth and deposition of sulfide-rich particulate components in a Kuwabara-type in situ incubator (KI incubator). Total hydrolyzed amino acids (THAA) and hydrolyzed hexosamines (HA) in AC ranged from 10.7 nmol/g to 64.0 nmol/g and from 0 nmol/g to 8.1 nmol/g, respectively, while THAA in hydrothermally altered core samples ranged from 26.0 nmol/g to 107.4 ...

Simulation of smoke plumes from large pool fires  

SciTech Connect (OSTI)

A large eddy simulation model of smoke plumes generated by large outdoor pool fires is presented. The plume is described in terms of steady-state convective transport by a uniform ambient wind of heated gases and particulate matter introduced into a stably stratified atmosphere by a continuously burning fire. The Navier-Stokes equations in the Boussinesq approximation are solved numerically with a constant eddy viscosity representing dissipation on length scales below the resolution limits of the calculation. The effective Reynolds number is high enough to permit direct simulation of the large scale mixing over two to three orders of magnitude in length scale. Particulate matter, or any nonreacting combustion product, is representing by Lagrangian particles that are advected by the fire-induced flow field. Background atmospheric motion is described in terms of the angular fluctuation of the prevailing wind and represented by random perturbations to the mean particle paths. Sample computations are presented and compared with plumes generated by large crude oil pool fires. Also presented is an assessment of the potential environmental hazard posed by burning marine oil spills.

Correlation of plume opacity with particles and sulfates from boilers  

SciTech Connect (OSTI)

The effects of emission concentrations of particulate matters and sulfates on plume opacity are investigated by in situ measurements. The studies are conducted for three processes of two coal-fired plants and one oil-fired that are all equipped with electrostatic precipitators. Flue-gas sampling and analysis include the concentrations of particles and total water soluble sulfates, particle size distribution, and flue-gas composition; while in-stack and out-of-stack opacities are determined by a transmissometer and certified smoke inspectors, respectively. Experimental results show that plume opacity outside the stack linearly correlates well with the in-stack opacity. The mixing of hot flue gas with cold ambient air would result in the condensation of hygroscopic sulfuric acid aerosols and an increase about 1.6% out of typical 15--25% measured opacity. An empirical equation similar to the Beer-Lambert-Bouger form is derived for predicting the plume opacity in terms of the stack diameter and the concentrations of particles and total water soluble sulfates. Good comparisons are achieved between predictions by the empirical equation and other available field data.

Propagation of an atmospheric pressure plasma plume  

SciTech Connect (OSTI)

The ''plasma bullet'' behavior of atmospheric pressure plasma plumes has recently attracted significant interest. In this paper, a specially designed plasma jet device is used to study this phenomenon. It is found that a helium primary plasma can propagate through the wall of a dielectric tube and keep propagating inside the dielectric tube (secondary plasma). High-speed photographs show that the primary plasma disappears before the secondary plasma starts to propagate. Both plumes propagate at a hypersonic speed. Detailed studies on the dynamics of the plasma plumes show that the local electric field induced by the charges on the surface of the dielectric tube plays an important role in the ignition of the secondary plasma. This indicates that the propagation of the plasma plumes may be attributed to the local electric field induced by the charges in the bulletlike plasma volume.

ANTARES deep sea neutrino telescope results  

SciTech Connect (OSTI)

The ANTARES experiment is currently the largest underwater neutrino telescope in the Northern Hemisphere. It is taking high quality data since 2007. Its main scientific goal is to search for high energy neutrinos that are expected from the acceleration of cosmic rays from astrophysical sources. This contribution reviews the status of the detector and presents several analyses carried out on atmospheric muons and neutrinos. For example it shows the results from the measurement of atmospheric muon neutrino spectrum and of atmospheric neutrino oscillation parameters as well as searches for neutrinos from steady cosmic point-like sources, for neutrinos from gamma ray bursts and for relativistic magnetic monopoles.

Passive remote smoke plume opacity sensing: a technique  

SciTech Connect (OSTI)

A new passive technique for the remote measurement of the visual opacity of plumes emerging from smokestacks is presented. It is based on the detection of the attenuation of the polarized component of Rayleigh-scattered background skylight as it traverses a smoke plume. A two-color difference measurement of the polarization of skylight through the plume is compared with a similar measurement of the unattenuated sky-light adjacent to the plume. This method is independent of the intrinsic brightness of the plume resulting from the scattering of sunlight and cancels white-light polarization effects of plume-scattered radiation. A prototype instrument incorporating this method has been successfully field tested on an EPA smoke school generator and a power plant stack plume.

Modeling mercury in power plant plumes  

SciTech Connect (OSTI)

Measurements of speciated mercury (Hg) downwind of coal-fired power plants suggest that the Hg{sup II}/(Hg{sup 0} + Hg{sup II}) ratio decreases significantly between the point of emission and the downwind ground-level measurement site, but that the SO{sub 2}/(Hg{sup 0} + Hg{sup II}) ratio is conserved. The authors simulated nine power plant plume events with the Reactive & Optics Model of Emissions (ROME), a reactive plume model that includes a comprehensive treatment of plume dispersion, transformation, and deposition. The model simulations fail to reproduce such a depletion in Hg{sup II}. A sensitivity study of the impact of the Hg{sup II} dry deposition velocity shows that a difference in dry deposition alone cannot explain the disparity. Similarly, a sensitivity study of the impact of cloud chemistry on results shows that the effect of clouds on Hg chemistry has only minimal impact. Possible explanations include Hg{sup II} reduction to Hg{sup 0} in the plume, rapid reduction of Hg{sup II} to Hg{sup 0} on ground surfaces, and/or an overestimation of the Hg{sup II} fraction in the power plant emissions. The authors propose that a chemical reaction not included in current models of atmospheric mercury reduces Hg{sup II} to Hg{sup 0} in coal-fired power plant plumes. The incorporation of two possible reduction pathways for Hg{sup II} shows better agreement between the model simulations and the ambient measurements. These potential Hg{sup II} to Hg{sup 0} reactions need to be studied in the laboratory to investigate this hypothesis. Because the speciation of Hg has a significant effect on Hg deposition, models of the fate and transport of atmospheric Hg may need to be modified to account for the reduction of Hg{sup II} in coal-fired power plant plumes if such a reaction is confirmed in further experimental investigations. 31 refs., 2 figs., 6 tabs.

Dynamics of femtosecond laser produced tungsten nanoparticle plumes  

SciTech Connect (OSTI)

We investigated the expansion features of femtosecond laser generated tungsten nanoparticle plumes in vacuum. Fast gated images showed distinct two components expansion features, viz., plasma and nanoparticle plumes, separated by time of appearance. The persistence of plasma and nanoparticle plumes are ?500 ns and ?100 ?s, respectively, and propagating with velocities differed by 25 times. The estimated temperature of the nanoparticles showed a decreasing trend with increasing time and space. Compared to low-Z materials (e.g., Si), ultrafast laser ablation of high-Z materials like W provides significantly higher nanoparticle yield. A comparison between the nanoparticle plumes generated by W and Si is also discussed along with other metals.

Paducah Gaseous Diffusion Plant Northwest Plume interceptor system evaluation  

SciTech Connect (OSTI)

The Paducah Gaseous Diffusion Plant (PGDP) recently installed an interceptor system consisting of four wells, evenly divided between two well fields, to contain the Northwest Plume. As stated in the Northwest Plume Record of Decision (ROD), groundwater will be pumped at a rate to reduce further contamination and initiate control of the northwest contaminant plume. The objective of this evaluation was to determine the optimum (minimal) well field pumping rates required for plume hotspot containment. Plume hotspot, as defined in the Northwest Plume ROD and throughout this report, is that portion of the plume with trichloroethene (TCE) concentrations greater than 1,000 {micro}g/L. An existing 3-dimensional groundwater model was modified and used to perform capture zone analyses of the north and south interceptor system well fields. Model results suggest that the plume hotspot is not contained at the system design pumping rate of 100 gallons per minute (gal/min) per well field. Rather, the modeling determined that north and south well field pumping rates of 400 and 150 gal/min, respectively, are necessary for plume hotspot containment. The difference between the design and optimal pumping rates required for containment can be attributed to the discovery of a highly transmissive zone in the vicinity of the two well fields.

The Effect of Vertical Upward Flow on Thermal Plumes The Effect of Vertical Upward Flow on Thermal Plumes Speaker(s): Pierre S. Farrugia Date: November 18, 2010 - 12:05pm Location: 90-3122 Seminar Host/Point of Contact: David Lorenzetti Thermal plumes have been widely investigated in a variety of scenarios, including natural convection and stratified environments. The resulting theory may be used to predict ventilation flow rates in, for example, natural and displacement ventilation, and under-floor air distribution (UFAD) systems. However, there has been little effort in investigating how uniform upward flows affect the plume velocity, rate of growth, and thermal profile. Such situations can arise if, for example, the diffusers of a UFAD system are evenly distributed. In order to study such situations, analytical expressions for the velocity and temperature profiles of a plume

Kuwaiti oil fires: Composition of source smoke  

SciTech Connect (OSTI)

While the Kuwaiti oil-fire smoke plumes manifested a pronounced impact on solar radiation in the Gulf region (visibility, surface temperatures, etc.), smoke plume concentrations of combustion-generated pollutants suggest that the overall chemical impact on the atmosphere of the smoke from these fires was probably much less than anticipated. Combustion in the Kuwaiti oil fires was surprisingly efficient, releasing on average more than 93% of the combusted hydrocarbon fuels as carbon dioxide (CO{sub 2}). Correspondingly, combustion-produced quantities of carbon monoxide (CO) and carbonaceous particles were low, each {approximately} 2% by weight. The fraction of methane (CH{sub 4}) produced by the fires was also relatively low ({approximately} 0.2%), but source emissions of nonmethane hydrocarbons were high ({approximately} 2%). Processes other than combustion (e.g., volatilization) probably contributed significantly to the measured in-plume hydrocarbon concentrations. Substantially, different elemental to organic carbon ratios were obtained for aerosol particles from several different types of fires/smokes. Sulfur emissions (particulate and gaseous) measured at the source fires were lower ({approximately} 0.5%) than predicted based on average sulfur contents in the crude. Sulfur dioxide measurements (SO{sub 2}) reported herein, however, were both limited in actual number and in the number of well fires sampled. Nitrous oxide (N{sub 2}O) emissions from the Kuwaiti oil fires were very low and often could not be distinguished from background concentrations. About 25-30% of the fires produced white smoke plumes that were found to be highly enriched in sodium and calcium chlorides. 18 refs., 1 fig., 4 tabs.

Results of source sampling at the Glens Falls cement kiln in Glens Falls, N.Y., are reported for sulfur oxides, ammonia, hydrochloric acid, oxygen, and moisture content. The origin of a detached, high-opacity, persistent plume originating from the cement kiln stack is investigated. It is proposed that this plume is due to ammonium salts of SOx and sulfuric acid that have been formed in condensed water droplets in the plume by the pseudocatalytic action of ammonia.

Saturated Zone Plumes in Volcanic Rock: Implications for Yucca Mountain  

SciTech Connect (OSTI)

This paper presents a literature survey of the occurrences of radionuclide plumes in saturated, fractured rocks. Three sites, Idaho National laboratory, Hanford, and Oak Ridge are discussed in detail. Results of a modeling study are also presented showing that the length to width ratio of a plume starting within the repository footprint at the Yucca Mountain Project site, decreases from about 20:1 for the base case to about 4:1 for a higher value of transverse dispersivity, indicating enhanced lateral spreading of the plume. Due to the definition of regulatory requirements, this lateral spreading does not directly impact breakthrough curves at the 18 km compliance boundary, however it increases the potential that a plume will encounter reducing conditions, thus significantly retarding the transport of sorbing radionuclides.

Updated Conceptual Model for the 300 Area Uranium Groundwater Plume  

SciTech Connect (OSTI)

The 300 Area uranium groundwater plume in the 300-FF-5 Operable Unit is residual from past discharge of nuclear fuel fabrication wastes to a number of liquid (and solid) disposal sites. The source zones in the disposal sites were remediated by excavation and backfilled to grade, but sorbed uranium remains in deeper, unexcavated vadose zone sediments. In spite of source term removal, the groundwater plume has shown remarkable persistence, with concentrations exceeding the drinking water standard over an area of approximately 1 km2. The plume resides within a coupled vadose zone, groundwater, river zone system of immense complexity and scale. Interactions between geologic structure, the hydrologic system driven by the Columbia River, groundwater-river exchange points, and the geochemistry of uranium contribute to persistence of the plume. The U.S. Department of Energy (DOE) recently completed a Remedial Investigation/Feasibility Study (RI/FS) to document characterization of the 300 Area uranium plume and plan for beginning to implement proposed remedial actions. As part of the RI/FS document, a conceptual model was developed that integrates knowledge of the hydrogeologic and geochemical properties of the 300 Area and controlling processes to yield an understanding of how the system behaves and the variables that control it. Recent results from the Hanford Integrated Field Research Challenge site and the Subsurface Biogeochemistry Scientific Focus Area Project funded by the DOE Office of Science were used to update the conceptual model and provide an assessment of key factors controlling plume persistence.

INDEPENDENT TECHNICAL REVIEW OF THE FOCUSED FEASIBILITY STUDY AND PROPOSED PLAN FOR DESIGNATED SOLID WASTE MANAGEMENT UNITS CONTRIBUTING TO THE SOUTHWEST GROUNDWATER PLUME AT THE PADUCAH GASEOUS DIFFUSION PLANT  

SciTech Connect (OSTI)

The U. S. Department of Energy (DOE) is currently developing a Proposed Plan (PP) for remediation of designated sources of chlorinated solvents that contribute contamination to the Southwest (SW) Groundwater Plume at the Paducah Gaseous Diffusion Plant (PGDP), in Paducah, KY. The principal contaminants in the SW Plume are trichloroethene (TCE) and other volatile organic compounds (VOCs); these industrial solvents were used and disposed in various facilities and locations at PGDP. In the SW plume area, residual TCE sources are primarily in the fine-grained sediments of the Upper Continental Recharge System (UCRS), a partially saturated zone that delivers contaminants downward into the coarse-grained Regional Gravel Aquifer (RGA). The RGA serves as the significant lateral groundwater transport pathway for the plume. In the SW Plume area, the four main contributing TCE source units are: (1) Solid Waste Management Unit (SWMU) 1 / Oil Landfarm; (2) C-720 Building TCE Northeast Spill Site (SWMU 211A); (3) C-720 Building TCE Southeast Spill Site (SWMU 211B); and (4) C-747 Contaminated Burial Yard (SWMU 4). The PP presents the Preferred Alternatives for remediation of VOCs in the UCRS at the Oil Landfarm and the C-720 Building spill sites. The basis for the PP is documented in a Focused Feasibility Study (FFS) (DOE, 2011) and a Site Investigation Report (SI) (DOE, 2007). The SW plume is currently within the boundaries of PGDP (i.e., does not extend off-site). Nonetheless, reasonable mitigation of the multiple contaminant sources contributing to the SW plume is one of the necessary components identified in the PGDP End State Vision (DOE, 2005). Because of the importance of the proposed actions DOE assembled an Independent Technical Review (ITR) team to provide input and assistance in finalizing the PP.

Ozone chemistry in the smoke from the Kuwait oil fires  

SciTech Connect (OSTI)

Ozone depletion occurred in the core of the plume of smoke from the Kuwait oil fires within 100 km of the fires, primarily in regions where NO{sub x} concentrations were high and ultraviolet flux was near zero. Rapid conversion of NO to NO{sub 2} can explain almost all of the ozone loss. Ozone was produced in diffuse regions of the plume, where the ultraviolet flux was higher than in the core. However, due to the relatively high ratio of nonmethane hydrocarbons to NO{sub x}, ozone production was slow. Since ozone was produced in a much larger volume than it was depleted, the plume as a whole was a source of ozone on a regional scale. 27 refs., 4 figs., 1 tab.

Calculating the probability of injected carbon dioxide plumes encountering faults  

SciTech Connect (OSTI)

One of the main concerns of storage in saline aquifers is leakage via faults. In the early stages of site selection, site-specific fault coverages are often not available for these aquifers. This necessitates a method using available fault data to estimate the probability of injected carbon dioxide encountering and migrating up a fault. The probability of encounter can be calculated from areal fault density statistics from available data, and carbon dioxide plume dimensions from numerical simulation. Given a number of assumptions, the dimension of the plume perpendicular to a fault times the areal density of faults with offsets greater than some threshold of interest provides probability of the plume encountering such a fault. Application of this result to a previously planned large-scale pilot injection in the southern portion of the San Joaquin Basin yielded a 3% and 7% chance of the plume encountering a fully and half seal offsetting fault, respectively. Subsequently available data indicated a half seal-offsetting fault at a distance from the injection well that implied a 20% probability of encounter for a plume sufficiently large to reach it.

Jet plume injection and combustion system for internal combustion engines  

DOE Patents [OSTI]

An improved combustion system for an internal combustion engine is disclosed wherein a rich air/fuel mixture is furnished at high pressure to one or more jet plume generator cavities adjacent to a cylinder and then injected through one or more orifices from the cavities into the head space of the cylinder to form one or more turbulent jet plumes in the head space of the cylinder prior to ignition of the rich air/fuel mixture in the cavity of the jet plume generator. The portion of the rich air/fuel mixture remaining in the cavity of the generator is then ignited to provide a secondary jet, comprising incomplete combustion products which are injected into the cylinder to initiate combustion in the already formed turbulent jet plume. Formation of the turbulent jet plume in the head space of the cylinder prior to ignition has been found to yield a higher maximum combustion pressure in the cylinder, as well as shortening the time period to attain such a maximum pressure.

Aerosol nucleation in coal-fired power-plant plumes  

Science Journals Connector (OSTI)

New-particle nucleation within coal-fired power-plant plumes can have large effects on particle number concentrations particularly near source regions with implications for human health and climate. In order to resolve the formation and growth of particles in these plumes we have integrated TwO-Moment Aerosol Sectional (TOMAS) microphysics in the System for Atmospheric Modelling (SAM) a large-eddy simulation/cloud-resolving model (LES/CRM). We have evaluated this model against aircraft observations for three case studies and the model reproduces well the major features of each case. Using this model we have shown that meteorology and background aerosol concentrations can have strong effects on new-particle formation and growth in coal-fired power-plant plumes even if emissions are held constant. We subsequently used the model to evaluate the effects of SO 2 and NOx pollution controls on newparticle formation in coal-fired power-plant plumes. We found that strong reductions in NOx emissions without concurrent reductions in SO 2 emissions may increase new-particle formation due to increases in OH formation within the plume. We predicted the change in new-particle formation due to changes in emissions between 1997 and 2010 for 330 coal-fired power plants in the US and we found a median decrease of 19% in new-particle formation. However the magnitude and sign of the aerosol changes depend greatly on the relative reductions in NOx and SO 2 emissions in each plant. More extensive plume measurements for a range of emissions of SO 2 and NOx and in varying background aerosol conditions are needed however to better quantify these effects.

Direct Measurement of Mercury Reactions In Coal Power Plant Plumes  

SciTech Connect (OSTI)

Recent field and pilot-scale results indicate that divalent mercury emitted from power plants may rapidly transform to elemental mercury within the power plant plumes. Simulations of mercury chemistry in plumes based on measured rates to date have improved regional model fits to Mercury Deposition Network wet deposition data for particular years, while not degrading model verification fits for remaining years of the ensemble. The years with improved fit are those with simulated deposition in grid cells in the State of Pennsylvania that have matching MDN station data significantly less than the model values. This project seeks to establish a full-scale data basis for whether or not significant reduction or oxidation reactions occur to mercury emitted from coal-fired power plants, and what numerical redox rate should apply for extension to other sources and for modeling of power plant mercury plumes locally, regionally, and nationally. Although in-stack mercury (Hg) speciation measurements are essential to the development of control technologies and to provide data for input into atmospheric fate and transport models, the determination of speciation in a cooling coal combustion plume is more relevant for use in estimating Hg fate and effects through the atmosphere. It is mercury transformations that may occur in the plume that determine the eventual rate and patterns of mercury deposited to the earth's surface. A necessary first step in developing a supportable approach to modeling any such transformations is to directly measure the forms and concentrations of mercury from the stack exit downwind to full dispersion in the atmosphere. As a result, a study was sponsored by EPRI and jointly funded by EPRI, the U.S Department of Energy (DOE), and the Wisconsin Department of Administration. The study was designed to further our understanding of plume chemistry. The study was carried out at the We Energies Pleasant Prairie Power Plant, Pleasant Prairie, Wisconsin, just west of Kenosha. Aircraft and ground measurements support the occurrence of a reduction in the fraction of reactive gaseous mercury (RGM) (with a corresponding increase in elemental mercury) as part of the Total Gaseous Mercury (TGM) emitted from the Pleasant Prairie stack. This occurrence is based on comparison of the RGM concentrations in the plume (at standard conditions) compared to the RGM in the stack. There was found to be a 44% drop in the fraction of RGM between the stack exit and the first sampling arc and a 66% reduction from the stack to the 5-mile sampling arc, with no additional drop between the 5- and 10-mile arcs. Smaller-scale experiments in both test chambers and pilot-scale coal combustor exhaust streams have indicated the presence of rapid and relatively complete reduction reactions converting divalent into elemental mercury within power plant plumes prior to full dispersion in the atmosphere. These measurements, however, have been unable to identify whether the reactions occur during plume rise from physical to virtual stack height (during positive thermal buoyancy). The presence, rate, completeness, ubiquity, and dependence on source characteristics of these reactions, however, must be demonstrated in plume environments associated with fully operational power plants. That requirement, to capture either the reactions or the reaction products of chemistry that may be occurring very close to stack exits in highly turbulent environments, constrains the precision and reproducibility with which such full-scale experiments can be carried out. The work described here is one of several initial steps required to test whether, and in what direction, such rapid mercury redox reactions might be occurring in such plumes.

DIRECT MEASUREMENT OF MERCURY REACTIONS IN COAL POWER PLANT PLUMES  

SciTech Connect (OSTI)

This project was awarded under U.S. Department of Energy (DOE) National Energy Technology Laboratory (NETL) Program Solicitation DE-PS26-02NT41422 and specifically addresses Program Area of Interest: No.5--Environmental and Water Resources. The project team includes the Electric Power Research Institute (EPRI) as the contractor and the University of North Dakota Energy & Environmental Research Center (EERC) and Frontier Geosciences as subcontractors. Wisconsin Energies and its Pleasant Prairie Power Plant acted as host for the field-testing portion of the research. The project is aimed at clarifying the role, rates, and end results of chemical transformations that may occur to mercury that has been emitted from elevated stacks of coal-fired electric power plants. Mercury emitted from power plants emerges in either its elemental, divalent, or particulate-bound form. Deposition of the divalent form is more likely to occur closer to the source than that of the other two forms, due to its solubility in water. Thus, if chemical transformations occur in the stack emissions plume, measurements in the stack may mischaracterize the fate of the material. Initial field and pilot plant measurements have shown significant and rapid chemical reduction of divalent to elemental mercury may occur in these plumes. Mercury models currently assume that the chemical form of mercury occurring in stacks is the same as that which enters the free atmosphere, with no alteration occurring in the emissions plume. Recent data indicate otherwise, but need to be evaluated at full operating scale under field conditions. Prestbo and others have demonstrated the likelihood of significant mercury chemical reactions occurring in power plant plumes (Prestbo et al., 1999; MDNR-PPRP, 2000; EERC, 2001). This experiment will thus increase our understanding of mercury atmospheric chemistry, allowing informed decisions regarding source attribution. The experiment was carried out during the period August 22-September 5, 2003. The experimental site was the Pleasant Prairie Power Plant in Pleasant Prairie, Wisconsin, just west of Kenosha. The experiment involved using an aircraft to capture emissions and document chemistry changes in the plume. While using the airplane for sampling, supplemental fast-response sensors for NOx, connected to data loggers, were used to gauge entry and exit times and transect intervals through plume emissions material. The Frontier Geosciences Static Plume Dilution Chamber (SPDC) was employed simultaneously adjacent to the stack to correlate its findings with the aircraft sampling, as well as providing evaluation of the SPDC as a rapid, less costly sampler for mercury chemistry. A complementary stack plume method, the Dynamic Plume Dilution (DPD) was used in the latter portion of the experiment to measure mercury speciation to observe any mercury reduction reaction with respect to both the reaction time (5 to 30 seconds) and dilution ratio. In addition, stack sampling using the ''Ontario Hydro'' wet chemistry method and continuous mercury monitors (CMM) were used to establish the baseline chemistry in the stack. Comparisons among stack, SPDC, DPD and aircraft measurements allow establishment of whether significant chemical changes to mercury occur in the plume, and of the verisimilitude of the SPDC and DPD methods. This progress report summarizes activities during a period of results review from the stack/aircraft subcontractor, data analysis and synthesis, and preparation and presentation of preliminary results to technical and oversight meetings.

Morphological Evolution of Thermal Plumes in Turbulent Rayleigh-Bnard Convection  

Science Journals Connector (OSTI)

An experimental study of the morphological evolution of thermal plumes in turbulent thermal convection is presented. Individual sheetlike plumes are extracted and their area, circumference, and heat content are found to all exhibit log-normal distributions. As the sheetlike plumes move across the plate they collide and convolute into spiraling swirls. These swirls then spiral away from the plates to become mushroomlike plumes which are accompanied by strong vertical vorticity. The measured profiles of plume numbers and of vertical vorticity quantify the morphological transition of sheetlike plumes to mushroomlike ones and the mixing and merging or clustering of mushroomlike plumes. The fluctuating vorticity is found to have the same exponential distribution and scaling behavior as the fluctuating temperature.

Chemical and physical properties of emissions from Kuwait oil fires  

SciTech Connect (OSTI)

After the Iraqi retreat from Kuwait in 1991, airborne sampling was conducted in the oil fire plumes near Kuwait City and ground-level samples were taken of the air within the city. For the airborne sampling, a versatile air pollution sampler was used to determine the SO(2), elemental concentrations, the aerosol mass loadings and SO4(2-) and NO3(1-) concentrations. Striking differences between the black and white plumes were associated with high concentrations of NaCl and CaCl(2) measured in the white plumes and large numbers of carbon chain agglomerates in the black plumes. For the ground-based measurements, an annular denuder system was used to determine levels of SO(2), SO4(2-), trace elements, and mass loadings. Certain pollutant levels rose in the city during inversion conditions, when winds were too weak to continue moving the combustion products directly to the Persian Gulf, and the increased levels of Pb and certain trace elements were comparable to those in other large urban areas in Europe.

Plume opacity investigation at a stoker-fired power generating station  

SciTech Connect (OSTI)

A public utility contacted the Conoco Coal Research Division through Consolidation Coal Company and requested technical assistance in determining the cause of a high plume opacity at one of their stoker-fired power generating stations. The sporadic occurrence of a high opacity plume (>20%) had been reported for several years. Although the utility was burning low sulfur coal, sulfuric acid mist had been suspected as the cause of the plume opacity; therefore, anhydrous ammonia had been injected into the flue gas at the ESP inlet plenums to control the plume opacity with some degree of success. However, for the last two years, the high plume opacity has occurred more frequently. The possible causes of the high plume opacity investigated were: 1) organic species emissions, 2) particulate mass loading, 3) particle size distribution, and 4) sulfuric acid emissions. The investigation included detailed sampling inside the boiler, stack, and plume areas. It was determined that the major cause of the high plume opacity was submicron particle growth at the stack exit due to sulfuric acid/water condensation. The larger particles more efficiently scattered light which resulted in the visible plume at the stack exit. The organic emissions and particulate mass loading in the stack flue gas had minimal effect on the high plume opacity. The fly ash size distribution would also have had minimal effect if the sulfuric acid had not been present.

Hydrotreating of oil from eastern oil shale  

SciTech Connect (OSTI)

Oil shale provides one of the major fossil energy reserves for the United States. The quantity of reserves in oil shale is less than the quantity in coal, but is much greater (by at least an order of magnitude) than the quantity of crude oil reserves. With so much oil potentially available from oil shale, efforts have been made to develop techniques for its utilization. In these efforts, hydrotreating has proved to be an acceptable technique for upgrading raw shale oil to make usuable products. The present work demonstrated the use of the hydrotreating technique for upgrading an oil from Indiana New Albany oil shale.

Properties of solar polar coronal plumes constrained by Ultraviolet Coronagraph Spectrometer data  

E-Print Network [OSTI]

We investigate the plasma dynamics (outflow speed and turbulence) inside polar plumes. We compare line profiles (mainly of \\ion{O}{6}) observed by the UVCS instrument on SOHO at the minimum of solar cycle 22-23 with model calculations. We consider Maxwellian velocity distributions with different widths in plume and inter-plume regions. Electron densities are assumed to be enhanced in plumes and to approach inter-plume values with increasing height. Different combinations of the outflow and turbulence velocity in the plume regions are considered. We compute line profiles and total intensities of the \\ion{H}{1} Ly$\\alpha$ and the \\ion{O}{6} doublets. The observed profile shapes and intensities are reproduced best by a small solar wind speed at low altitudes in plumes that increases with height to reach ambient inter-plume values above roughly 3-4 $R_\\sun$ combined with a similar variation of the width of the velocity distribution of the scattering atoms/ions. We also find that plumes very close to the pole give narrow profiles at heights above 2.5 $R_\\sun$, which are not observed. This suggests a tendency for plumes to be located away from the pole. We find that the inclusion of plumes in the model computations provides an improved correspondence with the observations and confirms previous results showing that published UVCS observations in polar coronal holes can be roughly reproduced without the need for large temperature anisotropy. The latitude distributions of plumes and magnetic flux distributions are studied by analyzing data from different instruments on SOHO and with SOLIS.

Comparison of predictions of the Hybrid Plume Dispersion Model with observations at the Kincaid power plant  

Science Journals Connector (OSTI)

The Hybrid Plume Dispersion Model (HPDM) has been evaluated with observations from a field experiment at the Kincaid power plant. HPDM is a dispersion model for buoyant plumes that employs parameterisations of boundary-layer wind, temperature, and turbulence profiles and Lagrangian time-scales. The model accounts for the bimodal distribution of turbulent velocities in the convective boundary layer and contains an algorithm for calculating the lofting of a buoyant plume against a capping inversion. The model predictions of maximum plume centreline concentrations show a mean bias of less than l0%, a typical error that is about 50% of the mean, and a correlation of about 0.5.

Development and application of a microcomputer based model for acid plume opacity  

SciTech Connect (OSTI)

Many stationary sources discharge visible emission into the atmosphere. A visible plume can be a problem either from the viewpoint of particulate emission standards or of aesthetics and public concern. In recent years, with the installation of high efficiency particulate emission control devices on utility and industrial boilers, detached plumes have become more of a problem because formerly the emission of primary particulate matter obscured and/or served as a condensing surface for the condensable material. In order to better understand the phenomenon of detached plumes, a model is formulated to describe in mathematical terms the relationship between the particle suspension leaving the stack and the particulate composition of the plume as it evolves downwind of the stack. This model provides a means of relating parameters that govern plum opacity which is not feasible from a monitoring standpoint. Input parameters can be put into the model to investigate the effects on resulting plume opacity levels.

Relation between plasma plume density and gas flow velocity in atmospheric pressure plasma  

SciTech Connect (OSTI)

We have studied atmospheric pressure plasma generated using a quartz tube, helium gas, and copper foil electrode by applying RF high voltage. The atmospheric pressure plasma in the form of a bullet is released as a plume into the atmosphere. To study the properties of the plasma plume, the plasma plume current is estimated from the difference in currents on the circuit, and the drift velocity is measured using a photodetector. The relation of the plasma plume density n{sub plu}, which is estimated from the current and the drift velocity, and the gas flow velocity v{sub gas} is examined. It is found that the dependence of the density on the gas flow velocity has relations of n{sub plu} ? log(v{sub gas}). However, the plasma plume density in the laminar flow is higher than that in the turbulent flow. Consequently, in the laminar flow, the density increases with increasing the gas flow velocity.

Initial parametric study of the flammability of plume releases in Hanford waste tanks  

SciTech Connect (OSTI)

This study comprised systematic analyses of waste tank headspace flammability following a plume-type of gas release from the waste. First, critical parameters affecting plume flammability were selected, evaluated, and refined. As part of the evaluation the effect of ventilation (breathing) air inflow on the convective flow field inside the tank headspace was assessed, and the magnitude of the so-called {open_quotes}numerical diffusion{close_quotes} on numerical simulation accuracy was investigated. Both issues were concluded to be negligible influences on predicted flammable gas concentrations in the tank headspace. Previous validation of the TEMPEST code against experimental data is also discussed, with calculated results in good agreements with experimental data. Twelve plume release simulations were then run, using release volumes and flow rates that were thought to cover the range of actual release volumes and rates. The results indicate that most plume-type releases remain flammable only during the actual release ends. Only for very large releases representing a significant fraction of the volume necessary to make the entire mixed headspace flammable (many thousands of cubic feet) can flammable concentrations persist for several hours after the release ends. However, as in the smaller plumes, only a fraction of the total release volume is flammable at any one time. The transient evolution of several plume sizes is illustrated in a number of color contour plots that provide insight into plume mixing behavior.

Chemical composition of emissions from the Kuwait oil fires  

SciTech Connect (OSTI)

Airborne measurements in the smoke from the Kuwait oil fires in May and June 1991 indicate that the combined oil and gas emissions were equivalent to the consumption of about 4.6 million barrels of oil per day. The combustion was relatively efficient, with about 96% of the fuel carbon burned emitted as CO{sub 2}. Particulate smoke emissions averaged 2% of the fuel burned, of which about 20% was soot. About two-thirds of the mass of the smoke was accounted for by salt, soot, and sulfate. The salt most likely originated from oil field brines, which were ejected from the wells along with the oil. The salt accounts for the fact that many of the plumes were white. SO{sub 2} and NO{sub x} were removed from the smoke at rates of about 6 and 22% per hour, respectively. The high salt and sulfate contents explain why a large fraction of the particles in the smoke were efficient cloud condensation nuclei. 14 refs., 3 figs., 1 tab.

Optical extinction of smoke from the Kuwait oil fires  

SciTech Connect (OSTI)

Aircraft-based measurements of optical extinction, optical scattering, and particle mass concentrations were obtained in the smoke from the Kuwait oil fires during May and June 1991. These measurements were used to derive optical absorption, single-scattering albedo ({anti {omega}}), specific absorption and the amount of soot in the smoke. Measurements were made in smoke from individual oil wells, pool fires and in composite smoke plumes. The value of {anti {omega}} for smoke from the individual fires was either 0.35-0.4 (for the black smoke) or 0.85-0.95 (for the white smoke). For the aged composite plume from all of the fires, {anti {omega}} ranged from 0.52 to 0.6. The specific absorption of the composite smoke varied from about 2 m{sup 2} g{sup {minus}1} near the fires to about 1.5 m{sup 2} g{sup {minus}1} well downwind. 8 refs., 2 figs., 1 tab.

Characterizing fault-plume intersection probability for geologic carbon sequestration risk assessment  

SciTech Connect (OSTI)

Leakage of CO{sub 2} out of the designated storage region via faults is a widely recognized concern for geologic carbon sequestration. The probability of such leakage can be separated into the probability of a plume encountering a fault and the probability of flow along such a fault. In the absence of deterministic fault location information, the first probability can be calculated from regional fault population statistics and modeling of the plume shape and size. In this study, fault statistical parameters were measured or estimated for WESTCARB's Phase III pilot test injection in the San Joaquin Valley, California. Combining CO{sub 2} plume model predictions with estimated fault characteristics resulted in a 3% probability that the CO{sub 2} plume will encounter a fault fully offsetting the 180 m (590 ft) thick seal. The probability of leakage is lower, likely much lower, as faults with this offset are probably low-permeability features in this area.

Economics of Peak Oil  

Science Journals Connector (OSTI)

Abstract Peak oil refers to the future decline in world production of crude oil and the accompanying potentially calamitous effects. The peak oil literature typically rejects economic analysis. This article argues that economic analysis is indeed appropriate for analyzing oil scarcity because standard economic models can replicate the observed peaks in oil production. Moreover, the emphasis on peak oil is misplaced as peaking is not a good indicator of scarcity, peak oil techniques are overly simplistic, the catastrophes predicted by the peak oil literature are unlikely, and the literature does not contribute to correcting identified market failures. Efficiency of oil markets could be improved by instead focusing on remedying market failures such as excessive private discount rates, environmental externalities, market power, insufficient innovation incentives, incomplete futures markets, and insecure property rights.

Radiative effects of the smoke clouds from the Kuwait oil fires  

SciTech Connect (OSTI)

The radiative effects of the smoke from the Kuwait oil fires were assessed by measuring downwelling and upwelling solar flux, as well as spectral solar extinction beneath, above, and within the smoke plume. Seven radiation flight missions were undertaken between May 16 and June 2, 1991, to characterize the plume between the source region in Kuwait and approximately 200 km south, near Manama, Bahrain. The authors present results from one flight representative of conditions of the composite plume. On May 18, 1991, in a homogeneous, well-mixed region of smoke approximately 100 km downstream of the fires, visible optical depths as high as 2 were measured, at which time transmission to the surface was 8%, while 78% of the solar radiation was absorbed by the smoke. The calculated instantaneous heating rate inside the plume reached 24 K/d. While these effects are probably typical of those regions in the Persian Gulf area directly covered by the smoke, there is no evidence to suggest significant climatic effects in other regions. 13 refs., 3 figs., 1 tab.

Models of the Shoemaker-Levy 9 Impacts. I. Ballistic Monte Carlo Plume  

Science Journals Connector (OSTI)

We model the plumes raised by impacting fragments of comet Shoemaker-Levy 9 to calculate synthetic plume views, atmospheric infall fluxes, and debris patterns. Our plume is a swarm of ballistic particles with one of several mass-velocity distributions (MVDs). The swarm is ejected instantaneously and uniformly into a cone from its apex. On falling to the ejection altitude, particles slide with horizontal deceleration following one of several schemes. The model ignores hydrodynamic and Coriolis effects. Initial conditions come from observations of plume heights and calculated or estimated properties of impactors. We adjust the plume tilt, opening angle, and minimum velocity and choose MVDs and sliding schemes to create impact patterns that match observations. Our best match uses the power-law MVD from the numerical impact model of Zahnle & Mac Low, with velocity cutoffs at 4.5 and 11.8 km s-1, a cone opening angle of 75, a cone tilt of 30 from vertical, and a sliding constant deceleration of 1.74 m s-2. A mathematically derived feature of Zahnle & Mac Low's published cumulative MVD is a thin shell of mass at the maximum velocity, corresponding to the former atmospheric shock front. This vanguard contains 22% of the mass and 45% of the energy of the plume and accounts for several previously unexplained observations, including the large, expanding ring seen at 3.2 ?m by McGregor et al. and the "third precursors" and "flare" seen near 300 and 1000 s, respectively, in the infrared light curves. We present synthetic views of the plumes in flight and after landing and derive infall fluxes of mass, energy, and vertical momentum as a function of time and position on the surface. These fluxes initialize a radiative-hydrodynamic atmosphere model (Paper II of this series) that calculates the thermal and dynamical response of the atmosphere and produces synthetic light curves.

Evolution of a Man-Made Plume in Coastal Waters  

SciTech Connect (OSTI)

The ability to understand the biogeophysical parameters that create ocean color in coastal waters is fundamental to the ability to exploit remote sensing for coastal applications. This article describes an experiment in which a controlled quantity of a single inorganic material with known absorption and scattering properties was released into a coastal environment. The plume experiment was conducted in conjunction with a Pacific Northwest National Laboratory (PNNL) field collection campaign in and around Sequim Bay on the Strait of Juan de Fuca in Washington State. The objective of the field campaign was to identify and characterize features in the near shore environment from the standpoint of quantifying environmental parameters to improve operational planning in littoral regions. The aerial component of the mission involved imagery acquisitions from the NRL's PHILLS hyperspectral sensor, and two commercial IR cameras. Coincident satellite data was obtained from commercial sources. Ground truth activities included atmospheric profiles, ground, surface water, and in-water spectral measurements, panels for radiometric calibration, water column water optics, water samples and profiles from support vessels, in-situ tide and weather measurements, and beach and intertidal transects and surveys (via scientific dive teams). This field collection campaign provided a unique opportunity for a multisensor data collection effort in littoral regions, to identify and characterize features from multiple platforms (satellite, aerial, water surface and subsurface) and sensors. Data from this mission is being used as input to both radiative transfer and ocean transport models, for characterizing the water column and the near-shore, and quantitatively estimating circulation and transport in coastal environments.

Utah Heavy Oil Program  

SciTech Connect (OSTI)

The Utah Heavy Oil Program (UHOP) was established in June 2006 to provide multidisciplinary research support to federal and state constituents for addressing the wide-ranging issues surrounding the creation of an industry for unconventional oil production in the United States. Additionally, UHOP was to serve as an on-going source of unbiased information to the nation surrounding technical, economic, legal and environmental aspects of developing heavy oil, oil sands, and oil shale resources. UHOP fulGilled its role by completing three tasks. First, in response to the Energy Policy Act of 2005 Section 369(p), UHOP published an update report to the 1987 technical and economic assessment of domestic heavy oil resources that was prepared by the Interstate Oil and Gas Compact Commission. The UHOP report, entitled 'A Technical, Economic, and Legal Assessment of North American Heavy Oil, Oil Sands, and Oil Shale Resources' was published in electronic and hard copy form in October 2007. Second, UHOP developed of a comprehensive, publicly accessible online repository of unconventional oil resources in North America based on the DSpace software platform. An interactive map was also developed as a source of geospatial information and as a means to interact with the repository from a geospatial setting. All documents uploaded to the repository are fully searchable by author, title, and keywords. Third, UHOP sponsored Give research projects related to unconventional fuels development. Two projects looked at issues associated with oil shale production, including oil shale pyrolysis kinetics, resource heterogeneity, and reservoir simulation. One project evaluated in situ production from Utah oil sands. Another project focused on water availability and produced water treatments. The last project considered commercial oil shale leasing from a policy, environmental, and economic perspective.

An experimental and computational study of moderately underexpanded rocket exhaust plumes in a co-flowing hypersonic free stream  

SciTech Connect (OSTI)

Rocket plume exhaust structures are aerodynamically and thermochemically very complex and the prediction of plume properties such as temperature, velocity, pressure, chemical species concentrations and turbulence properties is a formidable task as there are no definitive models for viscous and chemical effects. Contemporary computational techniques are still in their infancy and cannot yet reliably predict plume properties. Only through validation of computer codes using experimental data, can computational models be developed to the point where they can be confidently used as design and predictive tools. The motivation for this study was to acquire well defined data for rocket plumes at low altitude hypersonic flight conditions so that the above issues could be investigated.

Manufacture of refrigeration oils  

SciTech Connect (OSTI)

Lubricating oils suitable for use in refrigeration equipment in admixture with fluorinated hydrocarbon refrigerants are produced by solvent extraction of naphthenic lubricating oil base stocks, cooling the resulting extract mixture, optionally with the addition of a solvent modifier, to form a secondary raffinate and a secondary extract, and recovering a dewaxed oil fraction of lowered pour point from the secondary raffinate as a refrigeration oil product. The process of the invention obviates the need for a separate dewaxing operation, such as dewaxing with urea, as conventionally employed for the production of refrigeration oils.

Emission factors for particles, elemental carbon, and trace gases from the Kuwait oil fires  

SciTech Connect (OSTI)

Emission factors are presented for particles, elemental carbon (i.e., soot), total organic carbon in particles and vapor, and for various trace gases from the 1991 Kuwait oil fires. Particle emissions accounted for {approximately} 2% of the fuel burned. In general, soot emission factors were substantially lower than those used in recent {open_quotes}nuclear winter{close_quotes} calculations. Differences in the emissions and appearances of some of the individual fires are discussed. Carbon budget data for the composite plumes from the Kuwait fires are summarized; most of the burned carbon in the plumes was in the form of CO{sub 2}. Fluxes are presented for several combustion products. 26 refs., 1 fig., 5 tabs.

Inhibition Effect of Water Injection on Afterburning of Rocket Motor Exhaust Plume  

Science Journals Connector (OSTI)

One of the most important characteristic signatures of the exhaust plume from rocket motor is the afterburning phenomenon, and the injected water into the plume could inhibit the afterburning. The calculation model for the gas-liquid multiphase flow field with chemical reaction in the plume is built. By inducing the energy source terms caused by the vaporization of liquid water, condensation of the vapor and chemical reaction in the energy equation, the gas-liquid multiphase flow field and the afterburning phenomenon are calculated in a coupling way. Mixture multiphase flow model is used to calculate the gas-liquid flow field, and the vaporization mechanism is used to investigate the water vaporization process. The temperature contours are obtained and accord well with the experimental photos. The mass fraction contours of primary species are obtained, which can indicate the extent of inhibition effect of water injection on the afterburning phenomenon in the plume. When water is injected into the plume, the region of afterburning reduces a lot, and temperature on the ground wall declines rapidly, which can decrease the ablation of the combustion gas to the launch ground.

Crude Oil Analysis Database  

DOE Data Explorer [Office of Scientific and Technical Information (OSTI)]

The composition and physical properties of crude oil vary widely from one reservoir to another within an oil field, as well as from one field or region to another. Although all oils consist of hydrocarbons and their derivatives, the proportions of various types of compounds differ greatly. This makes some oils more suitable than others for specific refining processes and uses. To take advantage of this diversity, one needs access to information in a large database of crude oil analyses. The Crude Oil Analysis Database (COADB) currently satisfies this need by offering 9,056 crude oil analyses. Of these, 8,500 are United States domestic oils. The database contains results of analysis of the general properties and chemical composition, as well as the field, formation, and geographic location of the crude oil sample.

Experimental study on steam plume and temperature distribution for sonic steam jet  

Science Journals Connector (OSTI)

The sonic steam jet in subcooled water was investigated experimentally over a wide range of steam mass flux and water temperature conditions. Four different steam plume shapes were observed in present test conditions, and the condensation form was mainly controlled by the steam mass flux and water temperature. Moreover, the unstable jet was observed on the condition of low steam mass flux and high water temperature. The transition criterion of unstable-stable jet was also given. The temperature fields in the steam plume and in the surrounding water were measured. Axial temperature distributions represented the four typical steam plumes, and the fluctuation of axial temperature confirmed the existence of expansion and compression waves. Additionally, the radial temperature distributions were independent of water temperature for small radial distance at nozzle exit, and further the axial location was apart from the nozzle exit, longer the radial distance affected by the momentum diffusion.

Feather-like He plasma plumes in surrounding N2 gas  

Science Journals Connector (OSTI)

Effects of surrounding gases on the propagation of room-temperature atmospheric-pressure plasma jets are reported. A highly unusual feather-like plasma plume is observed only when N2 is used as surrounding gas. The He concentration on the axis at the starting point of the feather-like plume is ?0.85 of the maximum value and is independent on the He flow rates. High-speed optical imaging reveals that dim diffuse plasmas emerge just behind the bright head of the plasma bullet at the starting point of the feather-like plume. These results help tailoring surface exposure in emerging applications of plasma jets in medicine and nanotechnology.

This contract was awarded in response to a proposal in which a deployable plume and aerosol release prediction and tracking system would be designed, fabricated, and tested. The system would gather real time atmospheric data and input it into a real time atmospheric model that could be used for plume predition and tracking. The system would be able to be quickly deployed by aircraft to points of interest or positioned for deployment by vehicles. The system would provide three dimensional (u, v, and w) wind vector data, inversion height measurements, surface wind information, classical weather station data, and solar radiation. The on-board real time computer model would provide the prediction of the behavior of plumes and released aerosols.

In this letter, we report a cold microplasma generator at atmospheric pressure excited at 1 kHz in a pin to hole-electrode configuration by using soft materials partly. A nitrogen plasma plume with a length of more than 5 cm can be produced at low electrical power of 0.7 W without high feed gas pressure. The generator exhibits a compact structure with flexible property, which is suitable for treating thermally sensitive materials and biomedical materials, especially for delicate objects in an irregular confined space.

On formulating equations for plume spreads for near-surface releases  

Science Journals Connector (OSTI)

Recent concerns about effects of automobile emissions on the health of people living close to roads have motivated an examination of models to estimate dispersion in the surface boundary layer. This examination led to new formulations for horizontal and vertical plume spread described in Venkatram et al. (2013). Concentration estimates based on the proposed plume spread equations compare well with data from both the Prairie Grass experiment (Barad, 1958) as well as the recently conducted Idaho Falls experiment (Finn et al., 2010). This paper describes a simpler approach to deriving the new equations proposed in the earlier paper.

Oil shale technology  

SciTech Connect (OSTI)

Oil shale is undoubtedly an excellent energy source that has great abundance and world-wide distribution. Oil shale industries have seen ups and downs over more than 100 years, depending on the availability and price of conventional petroleum crudes. Market forces as well as environmental factors will greatly affect the interest in development of oil shale. Besides competing with conventional crude oil and natural gas, shale oil will have to compete favorably with coal-derived fuels for similar markets. Crude shale oil is obtained from oil shale by a relatively simple process called retorting. However, the process economics are greatly affected by the thermal efficiencies, the richness of shale, the mass transfer effectiveness, the conversion efficiency, the design of retort, the environmental post-treatment, etc. A great many process ideas and patents related to the oil shale pyrolysis have been developed; however, relatively few field and engineering data have been published. Due to the vast heterogeneity of oil shale and to the complexities of physicochemical process mechanisms, scientific or technological generalization of oil shale retorting is difficult to achieve. Dwindling supplied of worldwide petroleum reserves, as well as the unprecedented appetite of mankind for clean liquid fuel, has made the public concern for future energy market grow rapidly. the clean coal technology and the alternate fuel technology are currently of great significance not only to policy makers, but also to process and chemical researchers. In this book, efforts have been made to make a comprehensive text for the science and technology of oil shale utilization. Therefore, subjects dealing with the terminological definitions, geology and petrology, chemistry, characterization, process engineering, mathematical modeling, chemical reaction engineering, experimental methods, and statistical experimental design, etc. are covered in detail.

Investigation of the formation of a Portland Cement plant detached plume  

SciTech Connect (OSTI)

A gaseous and particulate-source emissions sampling program was conducted at a Portland Cement production plant in Rapid City, South Dakota. The study was conducted to determine the cause of the formation of an opaque detached plume from the plants' dry process kiln. The instack opacity of the emissions was less than 10% while the opacity of the plume five to ten stack diameters from the mouth of the stack was in excess of 40%, thus giving an appearance of a detached plume. The sampling and analysis program included particulate emissions measurements, particle sizing and composition, and measurements of gaseous and particle ammonia, chloride, fluoride, and sulfur dioxide. Extensive process materials sampling and analysis were also conducted. Based on the resulting data, one conclusion is that the opaque detached plume is the result of ammonium chloride particles formed by the reaction of gaseous ammonia and hydrochloric acid. It was also found that the ammonia in the cement plant was generated from the shale portion of the raw products when the raw product was passed through the heat exchanger.

Measurements of Outflow Velocities in On-Disk Plumes from EIS Hinode Observations  

E-Print Network [OSTI]

The contribution of plumes to the solar wind has been subject to hot debate in the past decades. The EUV Imaging Spectrometer (EIS) on board Hinode provides a unique means to deduce outflow velocities at coronal heights via direct Doppler shift measurements of coronal emission lines. Such direct Doppler shift measurements were not possible with previous spectrometers. We measure the outflow velocity at coronal heights in several on-disk long-duration plumes, which are located in coronal holes and show significant blue shifts throughout the entire observational period. In one case, a plume is measured 4 hours apart. The deduced outflow velocities are consistent, suggesting that the flows are quasi-steady. Furthermore, we provide an outflow velocity profile along the plumes, finding that the velocity corrected for the line-of-sight effect can reach 10 km s$^{-1}$ at 1.02 $R_{\\odot}$, 15 km s$^{-1}$ at 1.03 $R_{\\odot}$, and 25 km s$^{-1}$ at 1.05 $R_{\\odot}$.

Chapter 5 - Crude Oil  

Science Journals Connector (OSTI)

Abstract Oil has been the number one source of energy in the world since the middle of the twentieth century. The world is very dependent on petroleum for transportation fuels, petrochemicals and asphalt. But ever increasing demand has caused the price of oil to spike in recent years, and only the world economic crisis has been able to temper demand and bring the price down to more reasonable levels. However, the demand and price are likely to shoot up again when the economy recovers. At the same time, the peak oil theory of M. King Hubbert predicts that world oil production is likely to peak soon. This prediction raises questions about what source of energy will come to the fore when oil is not able to keep up.

Modeling basin- and plume-scale processes of CO2 storage for full-scale deployment  

SciTech Connect (OSTI)

Integrated modeling of basin- and plume-scale processes induced by full-scale deployment of CO{sub 2} storage was applied to the Mt. Simon Aquifer in the Illinois Basin. A three-dimensional mesh was generated with local refinement around 20 injection sites, with approximately 30 km spacing. A total annual injection rate of 100 Mt CO{sub 2} over 50 years was used. The CO{sub 2}-brine flow at the plume scale and the single-phase flow at the basin scale were simulated. Simulation results show the overall shape of a CO{sub 2} plume consisting of a typical gravity-override subplume in the bottom injection zone of high injectivity and a pyramid-shaped subplume in the overlying multilayered Mt. Simon, indicating the important role of a secondary seal with relatively low-permeability and high-entry capillary pressure. The secondary-seal effect is manifested by retarded upward CO{sub 2} migration as a result of multiple secondary seals, coupled with lateral preferential CO{sub 2} viscous fingering through high-permeability layers. The plume width varies from 9.0 to 13.5 km at 200 years, indicating the slow CO{sub 2} migration and no plume interference between storage sites. On the basin scale, pressure perturbations propagate quickly away from injection centers, interfere after less than 1 year, and eventually reach basin margins. The simulated pressure buildup of 35 bar in the injection area is not expected to affect caprock geomechanical integrity. Moderate pressure buildup is observed in Mt. Simon in northern Illinois. However, its impact on groundwater resources is less than the hydraulic drawdown induced by long-term extensive pumping from overlying freshwater aquifers.

In-situ plume diagnosis during pulsed laser deposition of epitaxial-oxide thin films  

SciTech Connect (OSTI)

The visible plume, induced during pulsed-laser deposition (PLD) of epitaxial La{sub 0.5}Sr{sub 0.5}CoO{sub 3}/Ba{sub 0.4}Sr{sub 0.6}TiO{sub 3}/La{sub 0.5}Sr{sub 0.5}CoO{sub 3}/YBa{sub 2}Cu{sub 3}O{sub 7}/YSZ heterostructures on silicon (100) wafers, was studied by optical-emission spectroscopy (OES). These films are suitable for the fabrication of ferroelectric capacitors and pyroelectric-sensor devices. A YAG laser, at 266 nm, is used for ablation. A collection lens transfers the PLD-plume emission into an optical fiber and onto a diffraction grating and a CCD array, for time-averaged spectroscopy from 410 to 640 nm. Plume emissions from ablated targets in the presence of an oxygen ambient, due to various atomic (Ba, Co, Cu, Sr, Ti, Y, Zr), ionic (Ba{sup +}, La{sup +}, Sr{sup +}, Y{sup +}), and a diatomic oxide (YO) species were identified. Emission intensity and evolution of ablated species are reported for distance away from the target surface, oxygen pressures, and laser fluences (1 to 4 J/cm{sup 2}). The behavior of reactive-product species, especially YO for plumes from yttria-stabilized zirconia (YSZ) and YBCO targets, is discussed. This simple and inexpensive OES system is suitable for use as a plume-quality monitor on routine PLD film synthesis.

Innovative Strategy For Long Term Monitoring Of Metal And Radionuclide Plumes  

SciTech Connect (OSTI)

Many government and private industry sites that were once contaminated with radioactive and chemical wastes cannot be cleaned up enough to permit unrestricted human access. The sites will require long term management, in some cases indefinitely, leaving site owners with the challenge of protecting human health and environmental quality at these "legacy" sites. Long-term monitoring of groundwater contamination is one of the largest projected costs in the life cycle of environmental management at the Savannah River Site, the larger DOE complex, and many large federal and private sites. There is a need to optimize the performance and manage the cost of long term surveillance and monitoring at their sites. Currently, SRNL is initiating a pilot field test using alternative protocols for long term monitoring of metals and radionuclides. A key component of the approach is that monitoring efforts are focused on measurement of low cost metrics related to hydrologic and chemical conditions that control contaminant migration. The strategy combines careful monitoring of hydrologic boundary conditions with measurement of master variables such as chemical surrogates along with a smaller number of standard well analyses. In plumes contaminated with metals, master variables control the chemistry of the groundwater system, and include redox variables (ORP, DO, chemicals), pH, specific conductivity, biological community (breakdown/decay products), and temperature. Significant changes in these variables will result in conditions whereby the plume may not be stable and therefore can be used to predict possible plume migration. Conversely, concentration measurements for all types of contaminants in groundwater are a lagging indicator plume movement - major changes contaminant concentrations indicate that contamination has migrated. An approach based on measurement of master variables and explicit monitoring of hydrologic boundary conditions combined with traditional metrics should lead to improved monitoring while simultaneously reducing costs. This paradigm is being tested at the SRS F-Area where an innovative passive remedial system is being monitored and evaluated over the long term prior to traditional regulatory closure. Contaminants being addressed at this site are uranium, strontium-90, iodine-129, and tritium. We believe that the proposed strategies will be more effective in early identification of potential risks; these strategies will also be cost effective because controlling variables are relatively simple to measure. These variables also directly reflect the evolution of the plume through time, so that the monitoring strategy can be modified as the plume 'ages'. This transformational long-term monitoring paradigm will generate large cost savings to DOE, other federal agencies and industry and will provide improved performance and leading indicators of environmental management performance.

The Vapor Plume at Material Disposal Are C in Relation to Pajarito Corridor Facilities  

SciTech Connect (OSTI)

A vapor plume made up of volatile organic compounds is present beneath Material Disposal Area C (MDA C) at Los Alamos National Laboratory (LANL). The location and concentrations within the vapor plume are discussed in relation to existing and planned facilities and construction activities along Pajarito Road (the 'Pajarito Corridor') and in terms of worker health and safety. This document provides information that indicates that the vapor plume does not pose a threat to the health of LANL workers nor will it pose a threat to workers during construction of proposed facilities along Pajarito Road. The Los Alamos National Laboratory (LANL or the Laboratory) monitors emissions, effluents, and environmental media to meet environmental compliance requirements, determine actions to protect the environment, and monitor the long-term health of the local environment. LANL also studies and characterizes 'legacy' waste from past Laboratory operations to make informed decisions regarding eventual corrective actions and the disposition of that waste. Starting in 1969, these activities have been annually reported in the LANL Environmental Report (formerly Environmental Surveillance Report), and are detailed in publicly accessible technical reports meeting environmental compliance requirements. Included among the legacy sites being investigated are several formerly used material disposal areas (MDAs) set aside by the Laboratory for the general on-site disposal of waste from mission-related activities. One such area is MDA C located in Technical Area 50 (TA-50), which was used for waste disposal between 1948 and 1974. The location of TA-50 is depicted in Figure 1. The present paper uses a series of maps and cross sections to address the public concerns raised about the vapor plume at MDA C. As illustrated here, extensive sampling and data interpretation indicate that the vapor plume at MDA C does not pose a threat to the health of LANL workers nor will it pose a threat to workers during construction of the proposed facilities and utility trenches. The public cannot be directly exposed to the vapor plume beneath MDA C because Pajarito Road is closed to the public.

Winter Crude Oil and  

Gasoline and Diesel Fuel Update (EIA)

4 4 Notes: While the relatively low stock forecast (although not as low as last winter) adds some extra pressure to prices, the price of crude oil could be the major factor affecting heating oil prices this winter. The current EIA forecast shows residential prices averaging $1.29 this winter, assuming no volatility. The average retail price is about 7 cents less than last winter, but last winter included the price spike in November 2000, December 2000, and January 2001. Underlying crude oil prices are currently expected to be at or below those seen last winter. WTI averaged over $30 per barrel last winter, and is currently forecast to average about $27.50 per barrel this winter. As those of you who watch the markets know, there is tremendous uncertainty in the amount of crude oil supply that will be available this winter. Less

Chain-aggregate aerosols in smoke from the Kuwait oil fires  

SciTech Connect (OSTI)

Electrooptical scattering was used to detect aggregated particle chains in the smoke from the Kuwait oil fires. Nonsphericity was detected by the change in light scattering brought about by induced alignment of particles when subjected to a pulsed, bipolar electric field. Measured parameters included the steady state enhancement of light scattering for complete orientation of the particles, and the rotational diffusion constant, calculated from the time required for the particles to relax to a random orientation after the electric field was removed. Chain aggregates of soot formed within seconds of combustion for those fires producing black smoke. These aggregates agglomerated to some extent in the smoke near the fires, but then remained relatively unchanged for several hours of travel downwind. Very little nonsphericity was detected for particles in the plume of white smoke, which consisted primarily of salt brine products emitted along with the oil. 10 refs., 4 figs., 1 tab.

Study of the spatial coherence of high order harmonic radiation generated from pre-formed plasma plumes  

SciTech Connect (OSTI)

A study of the spatial coherence of the high order harmonic radiation generated by the interaction of 45 fs Ti:sapphire laser beam with carbon (graphite) plasma plume has been carried out using Young's double slit interferometry. It is observed that the spatial coherence varies with harmonic order, laser focal spot size in plasma plume, and peaks at an optimal spot size. It is also observed that the spatial coherence is higher when the laser pulse is focused before the plasma plume than when focused after the plume, and it decreases with increase in the harmonic order. The optimum laser parameters and the focusing conditions to achieve good spatial coherence with high harmonic conversion have been identified, which is desirable for practical applications of the harmonic radiation.

Oil/gas collector/separator for underwater oil leaks  

DOE Patents [OSTI]

An oil/gas collector/separator for recovery of oil leaking, for example, from an offshore or underwater oil well. The separator is floated over the point of the leak and tethered in place so as to receive oil/gas floating, or forced under pressure, toward the water surface from either a broken or leaking oil well casing, line, or sunken ship. The separator is provided with a downwardly extending skirt to contain the oil/gas which floats or is forced upward into a dome wherein the gas is separated from the oil/water, with the gas being flared (burned) at the top of the dome, and the oil is separated from water and pumped to a point of use. Since the density of oil is less than that of water it can be easily separated from any water entering the dome.

Buoyant thermal plumes from planetary landers and rovers: Application to sizing of meteorological masts  

Science Journals Connector (OSTI)

AbstractObjective Landers on Mars and Titan may have warm surfaces as a result of solar heating or the carriage of radioisotope power sources. This warmth can perturb downwind meteorological measurements, but cannot be modeled as a simple aerodynamic wake because buoyant forces can be significant. Methods We use an analytic model from the industrial aerodynamics literature on smoke dispersion from fires and smokestacks to evaluate the plume trajectories. Computational Fluid Dynamics (CFD) simulations are also performed for a Titan lander. Results CFD yields results similar to the analytic model. (Albeit with a possibly weaker dependence on windspeed than the classic model.) We apply the models to evaluate the probability of immersion of instrumentation in plumes from the Mars Science Laboratory (MSL) Curiosity and for a Titan lander under various wind scenarios. Conclusions Lander perturbations can be easily calculated. Practice implications None.

Numerical simulation of nucleation scavenging within smoke plumes above large fires  

SciTech Connect (OSTI)

This paper presents preliminary results from an on-going smoke plume research project. The goal is to determine reasonable estimates of vertical distribution of smoke in the early post-nuclear-exchange environment, accounting for the air circulations forced by large, intense fires and for the possible prompt removal of smoke due to various scavenging mechanisms within pyrogenic clouds. These estimates may facilitate improved global-scale calculations by providing more accurate initial smoke distributions than have previously been available. Early results suggest that scavenging of smoke particles due to their activation as condensation nuclei may significantly reduce the amount of smoke available for climate modification. It appears that this scavenging process operates most efficiently in the smoke plumes which rise to the highest altitudes. Even if overseeding inhibits cloud droplet coalescence, rain may still form due to the collection of cloud droplets by very large aerosol particles.

The plume model MODIS: integration in the Hydro-Quebec shell  

Science Journals Connector (OSTI)

The comprehensive numerical model MODIS for the simulation of pollutant dispersion from a point source is integrated in the graphical shell of Hydro-Quebec. The shell has been developed by Hydro-Quebec to offer a valuable scheme for various applications of software products, which were originally conceived only for scientific purposes. MODIS, developed by the GKSS Research Centre Geesthacht and the Ontario Ministry of Environment, is a powerful simulation model, which calculates the behaviour of plumes in the lower atmosphere. The model was validated under a bilateral project in the framework of Canadian-German co-operation by using data of the EPRI Plume Model Validation Project. A further application of MODIS has been undertaken to determine the dispersion of gaseous mercury from a previous strong emission source located in the former German Democratic Republic.

Implementation of plume rise and its impacts on emissions and air quality modelling  

Science Journals Connector (OSTI)

Abstract This work analyses the impact of implementing hourly plume rise calculations over Spain in terms of: i) vertical emission allocations and ii) modelled air quality concentrations. Two air quality simulations (4kmנ4km, 1h) were performed for February and June 2009, using the CALIOPE-AQFS system (WRF-ARW/HERMESv2.0/CMAQ/BSC-DREAM8b) differing only by the vertical allocation of point source emissions: i) using fixed vertical profiles based on the stack height of each facility and ii) using an hourly bottom-up calculations of effective emission heights. When using plume rise calculations, emissions are generally allocated to lower altitudes than when using the fixed vertical profiles, showing significant differences depending on source sector and air pollutant (up to 75% between estimated average effective emission heights). In terms of air quality, it is shown that hourly plume rise calculations lead to improved simulation of industrial SO2 concentrations, thus increasing modelled concentrations (1.4?gm?3 increase in February, 1.5?gm?3 increase in June) and reducing the model biases for both months (31.1% in February, 73.7% in June). The increase of SO2 concentrations leads to an increase of SO 4 ? 2 surface levels that varies according to the season and location (4.3% in February and 0.4% in June, on average). On the other hand, the impact on NO2 and PM10 concentrations is less significant, leading to average changes of a few ?gm3 at most (0.4?gm?3 for NO2 and 0.2?gm?3 for PM10). In order to maximize the precision of plume rise calculations, the use of stack parameters based on real-world data is mandatory.

DETERMINATION OF PROMINENCE PLASMA {beta} FROM THE DYNAMICS OF RISING PLUMES  

SciTech Connect (OSTI)

Observations by the Hinode satellite show in great detail the dynamics of rising plumes, dark in chromospheric lines, in quiescent prominences that propagate from large ({approx}10 Mm) bubbles that form at the base of the prominences. These plumes present a very interesting opportunity to study magnetohydrodynamic (MHD) phenomena in quiescent prominences, but obstacles still remain. One of the biggest issues is that of the magnetic field strength, which is not easily measurable in prominences. In this paper we present a method that may be used to determine a prominence's plasma {beta} when rising plumes are observed. Using the classic fluid dynamic solution for flow around a circular cylinder with an MHD correction, the compression of the prominence material can be estimated. This has been successfully confirmed through simulations; application to a prominence gave an estimate of the plasma {beta} as {beta} = 0.47 {+-} 0.079 to 1.13 {+-} 0.080 for the range {gamma} = 1.4-1.7. Using this method it may be possible to estimate the plasma {beta} of observed prominences, therefore helping our understanding of a prominence's dynamics in terms of MHD phenomena.

Plume dispersion sensitivity to upper-level wind variations in a Chilean coastal environment  

SciTech Connect (OSTI)

Government and industry leaders in Chile are concerned with the impact of coastal smelter emissions on the air quality of surrounding communities and the inland capitol city of Santiago. The smelter emissions contain large amounts of sulfur and heavy metals. Because several large smelters are located along the coast, an air quality modeling system must be able to handle flow in both a coastal and mountainous environment. Linked seabreeze and mountain-induced slope flows which change in time and space have been best handled using prognostic numerical models. We are using a prognostic mesoscale meteorological model (HOTMAC - Higher-Order Turbulence Model for Atmospheric Circulation) linked to a random walk/puff model (RAPTAD - Random Particle Transport and Dispersion) in order to simulate plume transport over hundreds of kilometers. In this paper, we test the sensitivity of plume dispersion to variations in the prescribed wind direction. These tests were motivated by our desire to evaluate the effect of the uncertainties inherent in rawinsonde wind measurements and large-scale weather wind-field forecasts, which are often used as input to meteorological models, as well as to develop a climatology of plume transport direction based on prevailing wind direction.

A method to attenuate U(VI) mobility in acidic waste plumes using humic acids  

SciTech Connect (OSTI)

Acidic uranium (U) contaminated plumes have resulted from acid-extraction of plutonium during the Cold War and from U mining and milling operations. A sustainable method for in-situ immobilization of U under acidic conditions is not yet available. Here, we propose to use humic acids (HAs) for in-situ U immobilization in acidic waste plumes. Our laboratory batch experiments show that HA can adsorb onto aquifer sediments rapidly, strongly and practically irreversibly. Adding HA greatly enhanced U adsorption capacity to sediments at pH below 5.0. Our column experiments using historically contaminated sediments from the Savannah River Site under slow flow rates (120 and 12 m/y) show that desorption of U and HA were non-detectable over 100 pore-volumes of leaching with simulated acidic groundwaters. Upon HA-treatment, 99% of the contaminant [U] was immobilized at pH < 4.5, compared to 5% and 58% immobilized in the control columns at pH 3.5 and 4.5, respectively. These results demonstrated that HA-treatment is a promising in-situ remediation method for acidic U waste plumes. As a remediation reagent, HAs are resistant to biodegradation, cost effective, nontoxic, and easily introducible to the subsurface.

Weld seam tracking and lap weld penetration monitoring using the optical spectrum of the weld plume  

SciTech Connect (OSTI)

Joining of dissimilar materials is a long standing problem in manufacturing, with many tricks and special techniques developed to successfully join specific pairs of materials. Often, these special techniques impose stringent requirements on the process such as precise control of process parameters to achieve the desired joint characteristics. Laser welding is one of the techniques which has had some success in welding dissimilar metal alloys, and appears to be a viable process for these materials. Minimal heat input limits differential thermal expansion, and the small weld pool allows precise control of alloy mixing in the fusion zone. Obtaining optimal weld performance requires accurate monitoring and control of absorbed laser power and weld focus position. In order to monitor the laser welding process, the authors have used a small computer controlled optical spectrometer to observe the emission from the weld plume. Absorbed laser power can be related to the temperature of the weld pool surface and the plume above the weld. Focus position relative to the joint can easily be seen by the proportion of elements from each material existing in the plume. This monitor has been used to observe and optimize the performance of butt and lap welds between dissimilar alloys, where each alloy contains at least one element not found in the other alloy. Results will be presented for a copper-steel butt joint and a lap weld between stainless and low alloy steels.

Propagation dynamics of laterally colliding plasma plumes in laser-blow-off of thin film  

SciTech Connect (OSTI)

We report a systematic investigation of two plume interactions at different spatial separation (3-7?mm) in laser-blow-off. The plasmas plumes are created using Laser-blow-off (LBO) scheme of a thin film. The fast imaging technique is used to record the evolution of seed plasmas and the interaction zone which is formed as a result of interaction of the two seed plasmas. Time resolved optical emission spectroscopy is used to study evolution of optical emissions of the species present in the different regions of the plasmas. Neutral Li emissions (Li I 670.8?nm (2s {sup 2}S{sub 1/2} ? 2p {sup 2}P{sub 3/2,1/2}) and Li I 610.3?nm (2p {sup 2}P{sub 3/2,1/2} ? 3d {sup 2}D{sub 3/2,5/2})) are dominant in the plasmas but significant differences are observed in the emission and estimated plasma parameters of the seed and the interaction zone. The transport of plasma species from the seed plasmas to the interaction zone is discussed in the terms of plume divergence, kinetic energy of particles, and ion acoustic speed. An attempt is made to understand the formation and dynamics of the interaction zone in the colliding LBO seed plasmas.

Economic effects of peak oil  

Science Journals Connector (OSTI)

Assuming that global oil production peaked, this paper uses scenario analysis to show the economic effects of a possible supply shortage and corresponding rise in oil prices in the next decade on different sectors in Germany and other major economies such as the US, Japan, China, the OPEC or Russia. Due to the price-inelasticity of oil demand the supply shortage leads to a sharp increase in oil prices in the second scenario, with high effects on GDP comparable to the magnitude of the global financial crises in 2008/09. Oil exporting countries benefit from high oil prices, whereas oil importing countries are negatively affected. Generally, the effects in the third scenario are significantly smaller than in the second, showing that energy efficiency measures and the switch to renewable energy sources decreases the countries' dependence on oil imports and hence reduces their vulnerability to oil price shocks on the world market.

Hydrogeologic aspects of brine disposal in the East Poplar oil field, Fort Peck Indian Reservation, northeastern Montana  

SciTech Connect (OSTI)

The East Poplar Oil Field encompasses about 70 square miles in the south-central part of the Fort Peck Indian Reservation. Oil production began in 1952 from the Mississippian Madison Group. Production depths range from about 5,500 to 6,000 feet below land surface. Large quantities of brine (water having a dissolved-solids concentration greater than 35,000 milligrams per liter) have been produced with the oil. The brine has a dissolved-solids concentration of as much as 160,000 milligrams per liter. Most of the brine has been disposed of by injection into shallower subsurface formations (mainly the Lower Cretaceous Dakota Sandstone at depths of about 3,300 feet and the Upper Cretaceous Judith River Formation at depths of about 1,000 feet). Smaller quantities of brine have been directed to storage and evaporation pits. Handling, transport, and disposal of the brine have resulted in its movement into and migration through shallow Quaternary alluvial and glacial deposits along the Poplar River valley. Locally, domestic water supplies are obtained from these deposits. The major point, sources of shallow ground-water contamination probably is leakage of brine from corroded disposal-well casing and pipelines. Using electromagnetic geophysical techniques and auger drilling, three saline-water plumes in alluvial deposits and one plum in glacial deposits have been delineated. Dominant constituents in plume areas are sodium and chloride, whereas those in nonplume areas are sodium and bicarbonate.

Used oil re-refining  

SciTech Connect (OSTI)

Used oils, especially used lubricating oils which are normally considered waste and are discarded or burned, are reclaimed for reuse by a re-refining procedure involving the steps of: heat soaking the used oil; distilling the heat soaked oil; passing the distillate through a guard bed of activated material; hydrotreating the guard bed treated distillate under standard hydrotreating conditions. If the used oil to be re-refined contains a quantity of water and/or fuel fraction which the practioner considers sufficiently large to be detrimental, the used oil may be subjected to a dewatering/defueling step prior to being heat soaked.

That's up nearly 700,000 barrels per day from last year and the highest annual oil output since 1997 says the U.S. Energy Information Administration in its new monthly short-term energy outlook for September. EIA analyst Sam Gorgen explains: "Higher oil supplies, especially from North Dakota and Texas, boosted U.S. oil production. The number of on-shore drilling rigs targeting oil nationwide has increased by around 200 so far this year to just under 1,400 rigs."

Regional Residential Heating Oil Prices  

Gasoline and Diesel Fuel Update (EIA)

One of the first places where consumers are feeling the impact of One of the first places where consumers are feeling the impact of this winter's market pressures is in home heating oil prices. This chart shows prices through February 28, the most recent EIA data available. The general level of heating oil prices each year is largely a function of crude oil prices, and the price range over the course of the heating season is typically about 10 cents per gallon. Exceptions occur in unusual circumstances, such as very cold weather, large changes in crude oil prices, or supply problems. Heating oil prices for East Coast consumers started this winter at just over $1 per gallon, but rising crude oil prices drove them up nearly 21 cents through mid-January. With the continuing upward pressure from crude oil markets, magnified by a regional shortfall of heating oil

The report consists of (1) a status of oil shale development, (2) a description of the DOE Oil Shale Program, (3) an FY 86 oil shale research summary, and (4) a summary of FY 86 accomplishments. Discoveries were made in FY 86 about the physical and chemical properties and behavior of oil shales, process chemistry and kinetics, in situ retorting, advanced processes, and the environmental behavior and fate of wastes. The DOE Oil Shale Program shows an increasing emphasis on eastern US oil shales and in the development of advanced oil shale processing concepts. With the award to Foster Wheeler for the design of oil shale conceptual plants, the first step in the development of a systems analysis capability for the complete oil shale process has been taken. Unocal's Parachute Creek project, the only commercial oil shale plant operating in the United States, is operating at about 4000 bbl/day. The shale oil is upgraded at Parachute Creek for input to a conventional refinery. 67 refs., 21 figs., 3 tabs.

Naphthenic lube oils  

SciTech Connect (OSTI)

A process is disclosed for increasing the volume of lubricating oil base stocks recovered from a crude oil. A fraction having an atmospheric boiling range of about 675/sup 0/ to 1100/sup 0/ F. is recovered by vacuum distillation. This fraction is treated with furfural to extract a hydrocarbon mixture containing at least 50 volume % aromatic hydrocarbons. The raffinate is a lubricating oil base stock very high in paraffinic hydrocarbons and low in naphthenic hydrocarbons. The fraction extracted by the furfural contains at least about 50 volume % aromatic hydrocarbons and less than about 10 volume % paraffinic hydrocarbons. The mixture is hydrotreated to hydrogenate a substantial portion of the aromatic hydrocarbons. The hydrotreated product then is catalytically dewaxed. After removal of low boiling components, the finished lubricating oil base stock has a viscosity of at least about 200 SUS at 100/sup 0/ F., a pour point of less than 20/sup 0/ F. and contains at least 50 volume % of naphthenic hydrocarbons, a maximum of about 40 volume % aromatic hydrocarbons, and a maximum of about 10 volume % paraffinic hydrocarbons.

Peak oil supply or oil not for sale?  

Science Journals Connector (OSTI)

Abstract The restrictions imposed by climate change are inevitable and will be exerted either via precautionary mitigation of (mainly energy-related) CO2 emissions or via irreversible impacts on ecosystems and on human habitats. Either way, oil markets are bound to incur drastic shrinking. Concern over peak oil supply will crumble when the irrevocable peak oil demand is created. Replacing oil in the world's energy economies requires redirected market forces, notably in the form of steadily increasing oil end-use prices. Yet, thus far, crude oil prices have obeyed the market fundamentals of expanding-contracting demand and oligopolistic supply. A hockey stick supply curve supports high sales prices, providing large rents to submarginal sources. Cutting oil demand and maintaining high prices implies reducing the supply hockey stick's length by curtailing some oil producers. In such a scenario, the alliances, goals, and tactics of oil geopolitics are set to change. We identify a distribution over friendly and hostile oil suppliers, with others drifting in between the two sides. Conflicts and warfare are less aimed at conquering oil fields for exploitation than at paralyzing production capabilities of opponents or of unreliable transient sources. Covert warfare and instigation of internal conflicts are likely tactics to exhaust hostile opponents.

Structural Oil Pan With Integrated Oil Filtration And Cooling System  

DOE Patents [OSTI]

An oil pan for an internal combustion engine includes a body defining a reservoir for collecting engine coolant. The reservoir has a bottom and side walls extending upwardly from the bottom to present a flanged lip through which the oil pan may be mounted to the engine. An oil cooler assembly is housed within the body of the oil pan for cooling lubricant received from the engine. The body includes an oil inlet passage formed integrally therewith for receiving lubricant from the engine and delivering lubricant to the oil cooler. In addition, the body also includes an oil pick up passage formed integrally therewith for providing fluid communication between the reservoir and the engine through the flanged lip.

Constraining the reservoir model of an injected CO2 plume with crosswell CASSM at the Frio-II brine plot  

SciTech Connect (OSTI)

Crosswell CASSM (continuous active-source seismic monitoring) data was acquired as part of the Frio-II brine pilot CO{sub 2} injection experiment. To gain insight into the CO{sub 2} plume evolution, we have integrated the 3D multiphase flow modeling code TOUGH2 with seismic simulation codes via a petrophysical model that predicts seismic velocity for a given CO{sub 2} saturation. Results of forward seismic modeling based on the CO{sub 2} saturation distribution produced by an initial TOUGH2 model compare poorly with the CASSM data, indicating that the initial flow model did not capture the actual CO{sub 2} plume dynamics. Updates to the TOUGH2 model required to better match the CASSM field data indicate vertical flow near the injection well, with increased horizontal plume growth occurring at the top of the reservoir sand. The CASSM continuous delay time data are ideal for constraining the modeled spatiotemporal evolution of the CO{sub 2} plume and allow improvement in reservoir model and estimation of CO{sub 2} plume properties.

Estimating Plume Volume for Geologic Storage of CO2 in Saline Aquifers  

SciTech Connect (OSTI)

Typically, when a new subsurface flow and transport problem is first being considered, very simple models with a minimal number of parameters are used to get a rough idea of how the system will evolve. For a hydrogeologist considering the spreading of a contaminant plume in an aquifer, the aquifer thickness, porosity, and permeability might be enough to get started. If the plume is buoyant, aquifer dip comes into play. If regional groundwater flow is significant or there are nearby wells pumping, these features need to be included. Generally, the required parameters tend to be known from pre-existing studies, are parameters that people working in the field are familiar with, and represent features that are easy to explain to potential funding agencies, regulators, stakeholders, and the public. The situation for geologic storage of carbon dioxide (CO{sub 2}) in saline aquifers is quite different. It is certainly desirable to do preliminary modeling in advance of any field work since geologic storage of CO{sub 2} is a novel concept that few people have much experience with or intuition about. But the parameters that control CO{sub 2} plume behavior are a little more daunting to assemble and explain than those for a groundwater flow problem. Even the most basic question of how much volume a given mass of injected CO{sub 2} will occupy in the subsurface is non-trivial. However, with a number of simplifying assumptions, some preliminary estimates can be made, as described below. To make efficient use of the subsurface storage volume available, CO{sub 2} density should be large, which means choosing a storage formation at depths below about 800 m, where pressure and temperature conditions are above the critical point of CO{sub 2} (P = 73.8 bars, T = 31 C). Then CO{sub 2} will exist primarily as a free-phase supercritical fluid, while some CO{sub 2} will dissolve into the aqueous phase.

Application Of ERT For Tracking CO2 Plume Growth And Movement At The SECARB Cranfield Site  

SciTech Connect (OSTI)

Electrical Resistance Tomography (ERT) installed to track the development of an injected subsurface CO{sub 2} plume at the SECARB Cranfield, MS. sequestration site will be the deepest subsurface application of this method to date. ERT utilizes vertical arrays of electrodes, usually in a cross-well arrangement, to perform four-electrode measurements of changes in the spatial distribution of electrical resistance within a subsurface formation. Because a formation containing super-critical CO{sub 2} is approximately five times as resistive as its surroundings, significant resistance changes are anticipated during plume growth and movement within a brine-filled formation. ERT has also been shown to be quite sensitive to CO{sub 2} saturation changes. The Cranfield ERT electrode arrays will be emplaced at a depth exceeding 10,000 ft. (3280 m); the system design and installation must address significant challenges associated with both the depth and borehole conditions including temperatures of 258 F (126 C), pressures exceeding 5000 psi and a groundwater pH of 3. In addition, the system must allow co-located emplacement and concurrent operation with other monitoring techniques that utilize the same boreholes. ERT electrode and cabling will be attached to the outside of the well casing, allowing free access to the interior of the well, which is required by some of the other monitoring techniques being fielded. We will highlight these design challenges along with preliminary simulations indicating the anticipated level of imaging and the advantages of applying the technique in conjunction with other methods (such as cross-well seismics) to more accurately track the properties, location and movement of CO{sub 2} plumes.

The authors present their study on high-order harmonic generation pumped by 400 nm wavelength laser from plasma plumes produced on the surfaces of various solid-state targets. The maximum harmonic cutoff was observed for Be plasma (31st harmonic, {lambda}=12.9 nm). They compared these results with harmonic generation pumped by 800 nm wavelength laser. The authors demonstrated single harmonic enhancement for Cr, Sn, Sb, and Mn plasmas. They also studied the use of varying the chirp of the pump laser to control the enhancement of single harmonics within the plateau.

Measuring Dependence on Imported Oil  

Gasoline and Diesel Fuel Update (EIA)

Dependence on Imported Oil Dependence on Imported Oil by C. William Skinner* U.S. dependence on imported oil** can be measured in at least two ways. The differences hinge largely on whether oil imports are defined as net imports (total imports minus exports) or as total imports. EIA believes that the net-imports definition gives a clearer indication of the fraction of oil consumed that could not have been supplied from domestic sources and is thus the most appropriate measure. With this issue of the Monthly Energy Review, the Energy Information Administration (EIA) introduces a revised table that expresses depend- ence on imports in terms of both measures. How dependent is the United States on foreign oil? How dependent are we on oil from the Persian Gulf or other sensitive areas? Do we import more than we produce domes-

Slide 2 of 11 Notes: One of the first places where consumers are feeling the impact of this winter’s market pressures is in home heating oil prices. This chart shows prices through February 7, the most recent EIA data available. The general level of heating oil prices each year is largely a function of crude oil prices, and the price range over the course of the heating season is typically about 10 cents per gallon. Exceptions occur in unusual circumstances, such as very cold weather, large changes in crude oil prices, or supply problems. Heating oil prices for East Coast consumers started this winter at just over $1 per gallon, but rising crude oil prices drove them up nearly 21 cents per gallon through mid-January.

Oil shale retort apparatus  

DOE Patents [OSTI]

A retorting apparatus including a vertical kiln and a plurality of tubes for delivering rock to the top of the kiln and removal of processed rock from the bottom of the kiln so that the rock descends through the kiln as a moving bed. Distributors are provided for delivering gas to the kiln to effect heating of the rock and to disturb the rock particles during their descent. The distributors are constructed and disposed to deliver gas uniformly to the kiln and to withstand and overcome adverse conditions resulting from heat and from the descending rock. The rock delivery tubes are geometrically sized, spaced and positioned so as to deliver the shale uniformly into the kiln and form symmetrically disposed generally vertical paths, or "rock chimneys", through the descending shale which offer least resistance to upward flow of gas. When retorting oil shale, a delineated collection chamber near the top of the kiln collects gas and entrained oil mist rising through the kiln.

SciTech Connect (OSTI)

This Test Plan describes a laboratory-testing program to be performed at Pacific Northwest National Laboratory (PNNL) in support of the 300-FF-5 Feasibility Study (FS). The objective of the proposed treatability test is to evaluate the efficacy of using polyphosphate injections to treat uranium contaminated groundwater in situ. This study will be used to: (1) Develop implementation cost estimates; (2) Identify implementation challenges; and (3) Investigate the technology's ability to meet remedial objectives These activities will be conducted in parallel with a limited field investigation, which is currently underway to more accurately define the vertical extent of uranium in the vadose zone, and in the capillary fringe zone laterally throughout the plume. The treatability test will establish the viability of the method and, along with characterization data from the limited field investigation, will provide the means for determining how best to implement the technology in the field. By conducting the treatability work in parallel with the ongoing Limited Field Investigation, the resulting Feasibility Study (FS) will provide proven, site-specific information for evaluating polyphosphate addition and selecting a suitable remediation strategy for the uranium plume within the FS time frame at an overall cost savings.

Emulsified industrial oils recycling  

SciTech Connect (OSTI)

The industrial lubricant market has been analyzed with emphasis on current and/or developing recycling and re-refining technologies. This task has been performed for the United States and other industrialized countries, specifically France, West Germany, Italy and Japan. Attention has been focused at emulsion-type fluids regardless of the industrial application involved. It was found that emulsion-type fluids in the United States represent a much higher percentage of the total fluids used than in other industrialized countries. While recycling is an active matter explored by the industry, re-refining is rather a result of other issues than the mere fact that oil can be regenerated from a used industrial emulsion. To extend the longevity of an emulsion is a logical step to keep expenses down by using the emulsion as long as possible. There is, however, another important factor influencing this issue: regulations governing the disposal of such fluids. The ecological question, the respect for nature and the natural balances, is often seen now as everybody's task. Regulations forbid dumping used emulsions in the environment without prior treatment of the water phase and separation of the oil phase. This is a costly procedure, so recycling is attractive since it postpones the problem. It is questionable whether re-refining of these emulsions - as a business - could stand on its own if these emulsions did not have to be taken apart for disposal purposes. Once the emulsion is separated into a water and an oil phase, however, re-refining of the oil does become economical.

American oil producers are expected to pump a daily average of 6.4 million barrels of crude oil this year, according to the U.S. Energy Information Administrator's new monthly energy forecast. The annual increase in oil output tops the previous record set in 1951 and marks the largest yearly production increase ever. Most of the increase in crude oil production is driven by drilling activity in shale formations located in Texas, North Dakota and Montana.

Shelf and deep-sea sedimentary environments and physical benthic disturbance regimes: A review and synthesis  

Science Journals Connector (OSTI)

Abstract Physical disturbances of the seafloor play a key role in ecosystem function and are postulated to exert control over spatial patterns of biodiversity. This review investigates the role of natural physical sedimentological processes that occur in shelf, slope and abyssal environments that also act as disturbances to benthic ecosystems and which, under certain circumstances, give rise to benthic disturbance regimes. Physical sedimentological processes can cause both press (process that causes a disturbance by acting over a timespan that is intolerable to benthos) and pulse (process that causes a disturbance by exceeding a threshold above which benthos are unable to remain attached to the seabed or are buried under rapidly deposited sediment) types of disturbance. On the continental shelf, pulse-type disturbances are due to temperate and tropical storm events, and press-type of disturbances identified here are due to the migration of bedforms and other sand bodies, and sustained periods of elevated turbidity caused by seasonally reversing wind patterns. On the continental slope and at abyssal depths, pulse-type disturbances are due to slumps, turbidity currents; benthic storms may cause either press or pulse type disturbances. A possible press-type of disturbance identified here is inter-annual changes in abyssal bottom current speed and/or direction. It is concluded that: 1) physical sedimentary disturbance regimes may characterize as much as 10% of the global ocean floor; 2) multidisciplinary research programs that integrate oceanography, sedimentology and benthic ecology to collect time series observational data sets are needed to study disturbance regimes; and 3) predictive habitat suitability modeling must include disturbance regime concepts, along with other biophysical variables that define the fundamental niches of marine species, in order to advance.

The Genome of Deep-Sea Vent Chemolithoautotroph Thiomicrospiracrunogena XCL-2  

SciTech Connect (OSTI)

Presented here is the complete genome sequence ofThiomicrospira crunogena XCL-2, representative of ubiquitouschemolithoautotrophic sulfur-oxidizing bacteria isolated from deep-seahydrothermal vents. This gammaproteobacterium has a single chromosome(2,427,734 bp), and its genome illustrates many of the adaptations thathave enabled it to thrive at vents globally. It has 14 methyl-acceptingchemotaxis protein genes, including four that may assist in positioningit in the redoxcline. A relative abundance of CDSs encoding regulatoryproteins likely control the expression of genes encoding carboxysomes,multiple dissolved inorganic nitrogen and phosphate transporters, as wellas a phosphonate operon, which provide this species with a variety ofoptions for acquiring these substrates from the environment. T. crunogenaXCL-2 is unusual among obligate sulfur oxidizing bacteria in relying onthe Sox system for the oxidation of reduced sulfur compounds. A 38 kbprophage is present, and a high level of prophage induction was observed,which may play a role in keeping competing populations of close relativesin check. The genome has characteristics consistent with an obligatelychemolithoautotrophic lifestyle, including few transporters predicted tohave organic allocrits, and Calvin-Benson-Bassham cycle CDSs scatteredthroughout the genome.

Measurements of light transmission in deep sea with the AC9 trasmissometer  

E-Print Network [OSTI]

The NEMO Collaboration aims to construct an underwater Cerenkov detector in the Mediterranean Sea, able to act as a neutrino telescope. One of the main tasks of this project, which implies difficult technological challenges, is the selection of an adequate marine site. In this framework the knowledge of light transmission properties in deep seawater is extremely important. The collaboration has measured optical properties in several marine sites near the Italian coasts, at depths >3000 m, using a set-up based on a AC9, a commercial trasmissometer, manufactured by WETLabs. The results obtained for the two sites reported in this paper Alicudi and Ustica, show that deep seawater optical properties are comparable to those of the clearest waters.

Ophiolites of the deep-sea trenches of the western Pacific  

SciTech Connect (OSTI)

Igneous and metamorphic rocks of ophiolites are widespread in the basement of the Izu-Bonin, Volcano, Mariana, Philippine, Yap, Palau, New Hebrides, West Melanesian, Tonga, and Mussau trenches. Ophiolite in the trenches includes (1) metamorphic rocks ranging from low-T and low P to high-T and moderate P; (2) serpentinites after harzburgite; (3) ultramafic-mafic layered series; (4) tholeiitic basalts, dolerites, and their metamorphosed varieties; and (5) rocks of the boninitic series. Two geodynamic stages could be distinguished in the formation of the ophiolites of the Western Pacific. At the rifting stage, mantle diapir ascended during rifting and magmatic series were formed. In this period, rocks underwent intense low-temperature metasomatic alterations in the zones of heated seawater circulation. At the compression stage (subduction zone) regional pressure metamorphism of the ophiolites superimposed on the low-temperature metasomatic processes.

Climate change and the collapse of the Akkadian empire: Evidence from the deep sea  

SciTech Connect (OSTI)

The Akkadian empire ruled Mesopotamia from the headwaters of the Tigris-Euphrates Rivers to the Persian Gulf during the late third millennium B.C. Archeological evidence has shown that this highly developed civilization collapsed abruptly near 4,170 {+-} 150 calendar yr B.P., perhaps related to a shift to more arid conditions. Detailed paleoclimate records to test this assertion from Mesopotamia are rare, but changes in regional aridity are preserved in adjacent ocean basins. The authors document Holocene changes in regional aridity using mineralogic and geochemical analyses of a marine sediment core from the Gulf of Oman, which is directly downwind of Mesopotamian dust source areas and archeological sites. Results document a very abrupt increase in eolian dust and Mesopotamian aridity, accelerator mass spectrometer radiocarbon dates to 4,025 {+-} 125 calendar yr B.P., which persisted for {approximately} 300 yr. Radiogenic (Nd and Sr) isotope analyses confirm that the observed increase in mineral dust was derived from Mesopotamian source areas. Geochemical correlation of volcanic ash shards between the archeological site and marine sediment record establishes a direct temporal link between Mesopotamian aridification and social collapse, implicating a sudden shift to more arid conditions as a key factor contributing to the collapse of the Akkadian empire.
