Antarctic terrestrial ecosystems  

SciTech Connect

The Maritime and Continental Antarctic terrestrial ecosystems are considered in the context of environmental impacts - habitat destruction, alien introductions, and pollution. Four types of pollution are considered: nutrients, radionuclides, inert materials, and noxious chemicals. Their ability to recover from perturbation is discussed in the light of present scientific knowledge, and the methods used to control impacts are reviewed. It is concluded that techniques of waste disposal are still inadequate, adequate training in environmental and conservation principles for Antarctic personnel in many countries is lacking, and scientific investigations may be a much more serious threat than tourism to the integrity of these ecosystems. Some priorities crucial to future management are suggested.

The terrestrial ecosystem program for the Yucca Mountain Project  

SciTech Connect

DOE has implemented a program to monitor and mitigate impacts associated with site Characterization Activities at Yucca Mountain on the environment. This program has a sound experimental and statistical base. Monitoring data has been collected for parts of the program since 1989. There have been numerous changes in the Terrestrial Ecosystems Program since 1989 that reflect changes in the design and locations of Site Characterization Activities. There have also been changes made in the mitigation techniques implemented to protect important environmental resources based on results from the research efforts at Yucca Mountain. These changes have strengthened DOE efforts to ensure protection of the environmental during Site Characterization. DOE,has developed and implemented an integrated environmental program that protects the biotic environment and will restore environmental quality at Yucca Mountain.

Assessing net ecosystem carbon exchange of U S terrestrial ecosystems by integrating eddy covariance flux measurements and satellite observations  

SciTech Connect

More accurate projections of future carbon dioxide concentrations in the atmosphere and associated climate change depend on improved scientific understanding of the terrestrial carbon cycle. Despite the consensus that U.S. terrestrial ecosystems provide a carbon sink, the size, distribution, and interannual variability of this sink remain uncertain. Here we report a terrestrial carbon sink in the conterminous U.S. at 0.63 pg C yr 1 with the majority of the sink in regions dominated by evergreen and deciduous forests and savannas. This estimate is based on our continuous estimates of net ecosystem carbon exchange (NEE) with high spatial (1 km) and temporal (8-day) resolutions derived from NEE measurements from eddy covariance flux towers and wall-to-wall satellite observations from Moderate Resolution Imaging Spectroradiometer (MODIS). We find that the U.S. terrestrial ecosystems could offset a maximum of 40% of the fossil-fuel carbon emissions. Our results show that the U.S. terrestrial carbon sink varied between 0.51 and 0.70 pg C yr 1 over the period 2001 2006. The dominant sources of interannual variation of the carbon sink included extreme climate events and disturbances. Droughts in 2002 and 2006 reduced the U.S. carbon sink by 20% relative to a normal year. Disturbances including wildfires and hurricanes reduced carbon uptake or resulted in carbon release at regional scales. Our results provide an alternative, independent, and novel constraint to the U.S. terrestrial carbon sink.

Deep Atomic Binding (DAB) Approach in Interpretation of Fission Products Behavior in Terrestrial and Water Ecosystems  

SciTech Connect

A large number of studies and models were established to explain the fission products (FP) behavior within terrestrial and water ecosystems, but a number of behaviors were non understandable, which always attributed to unknown reasons. According to DAB hypothesis, almost all fission products behaviors in terrestrial and water ecosystems could be interpreted in a wide coincidence. The gab between former models predictions, and field behavior of fission products after accidents like Chernobyl have been explained. DAB represents a tool to reduce radio-phobia as well as radiation protection expenses. (author)

Impacts of Environmental Nanoparticles on Chemical, Biological and Hydrological Processes in Terrestrial Ecosystems  

SciTech Connect

This chapter provides insights on nanoparticle (NP) influence or control on the extent and timescales of single or coupled physical, chemical, biological and hydrological reactions and processes that occur in terrestrial ecosystems. Examples taken from the literature that show how terrestrial NPs may determine the fate of the aqueous and sorbed (adsorbed or precipitated) chemical species of nutrients and contaminants, are also included in this chapter. Specifically, in the first section, chapter objectives, term definitions and discussions on size-dependent properties, the origin and occurrence of NP in terrestrial ecosystems and NP toxicity, are included. In the second section, the topic of the binary interactions of NPs of different sizes, shapes, concentrations and ages with the soil solution chemical species is covered, focusing on NP formation, stability, aggregation, ability to serve as sorbents, or surface-mediated precipitation catalysts, or electron donors and acceptors. In the third section, aspects of the interactions in the ternary systems composed of environmental NP, nutrient/contaminant chemical species, and the soil/sediment matrix are discussed, focusing on the inhibitory and catalytic effects of environmental NP on nutrient/contaminant advective mobility and mass transfer, adsorption and desorption, dissolution and precipitation and redox reactions that occur in terrestrial ecosystems. These three review sections are followed by a short summary of future research needs and directions, the acknowledgements, the list of the references, and the figures.

Quantifying the role of fire in the Earth system - Part 2: Impact on the net carbon balance of global terrestrial ecosystems for the 20th century  

SciTech Connect

Fire is the primary terrestrial ecosystem disturbance agent on a global scale. It affects carbon balance of global terrestrial ecosystems by emitting carbon to atmosphere directly and immediately from biomass burning (i.e., fire direct effect), and by changing net ecosystem productivity and land-use carbon loss in post-fire regions due to biomass burning and fire-induced vegetation mortality (i.e., fire indirect effect). Here, we provide the first quantitative assessment about the impact of fire on the net carbon balance of global terrestrial ecosystems for the 20th century, and investigate the roles of fire direct and indirect effects. This study is done by quantifying the difference between the 20th century fire-on and fire-off simulations with NCAR community land model CLM4.5 as the model platform. Results show that fire decreases net carbon gain of the global terrestrial ecosystems by 1.0 Pg C yr-1 average across the 20th century, as a results of fire direct effect (1.9 Pg C yr-1) partly offset by indirect effect (-0.9 Pg C yr-1). Fire generally decreases the average carbon gains of terrestrial ecosystems in post-fire regions, which are significant over tropical savannas and part of forests in North America and the east of Asia. The general decrease of carbon gains in post-fire regions is because fire direct and indirect effects have similar spatial patterns and the former (to decrease carbon gain) is generally stronger. Moreover, the effect of fire on net carbon balance significantly declines prior to ~1970 with trend of 8 Tg C yr-1 due to increasing fire indirect effect and increases afterward with trend of 18 Tg C yr-1 due to increasing fire direct effect.

Radiological bioconcentration factors for aquatic, terrestrial, and wetland ecosystems at the Savannah River site  

SciTech Connect

Since the early 1950s, the Savannah River Site (SRS) released over 50 radionuclides into the environment while producing nuclear defense materials. These releases directly exposed aquatic and terrestrial biota to ionizing radiation from surface water, soil, and sediment, and also indirectly by the ingestion of items in the food chain. As part of new missions to develop waste management strategies and identify cost-effective environmental restoration options, knowledge concerning the uptake and distribution of these radionuclides is essential. This report compiles and summarizes site-specific bioconcentration factors for selected radionuclides released at SRS.

Radiological bioconcentration factors for aquatic, terrestrial, and wetland ecosystems at the Savannah River Site  

SciTech Connect

As a result of operations at the Savannah River Site (SRS), over 50 radionuclides have been released to the atmosphere and to onsite streams and seepage basins. Now, many of these radionuclides are available to aquatic and/or terrestrial organisms for uptake and cycling through the food chain. Knowledge about the uptake and cycling of these radionuclides is now crucial in evaluating waste management and clean-up alternatives for the site. Numerous studies have been conducted at the SRS over the past forty years to study the uptake and distribution of radionuclides in the Savannah River Site environment. In many instances, bioconcentration factors have been calculated to quantify the uptake of a radionuclide by an organism from the surrounding medium (i.e., soil or water). In the past, it has been common practice to use bioconcentration factors from the literature because site-specific data were not readily available. However, because of the variability of bioconcentration factors due to experimental or environmental conditions, site-specific data should be used when available. This report compiles and summarizes site-specific bioconcentration factors for selected radionuclides released at the Savannah River Site (SRS). An extensive literature search yielded site-specific bioconcentration factors for cesium, strontium, cobalt, plutonium, americium, curium, and tritium. These eight radionuclides have been the primary radionuclides studied at SRS because of their long half lives or because they are major contributors to radiological dose from exposure. For most radionuclides, it was determined that the site-specific bioconcentration factors were higher than those reported in literature. This report also summarizes some conditions that affect radionuclide bioavailability to and bioconcentration by aquatic and terrestrial organisms.

Science Journals Connector (OSTI)

This article addresses interdisciplinary sustainable aspects of fisheries as linkages for the adaptive management of large marine ecosystems (LMEs). Natural and human-induced impacts on living marine resources are considered. Management and the ecological aspects of fish stock populations in the United States Northeast Continental Shelf ecosystem are examined for prospective and emerging best practices from a synthesis of the scientific literature. With the passage of the Oceans Act of 2000 (Public Law 106256; e.g. Watkins 2002) in the United States, this article seeks to enhance the fostering of sustainability through natural and social science by forging linkages between the best available science practice and the precautionary approach that includes ecosystem considerations of fish stocks as component parts of a representative model LME.

Final Report on "Rising CO2 and Long-term Carbon Storage in Terrestrial Ecosystems: An Empirical Carbon Budget Validation"  

SciTech Connect

The primary goal of this report is to report the results of Grant DE-FG02-97ER62458, which began in 1997 as Grant DOE-98-59-MP-4 funded through the TECO program. However, this project has a longer history because DOE also funded this study from its inception in 1985 through 1997. The original grant was focused on plant responses to elevated CO2 in an intact ecosystem, while the latter grant was focused on belowground responses. Here we summarize the major findings across the 25 years this study has operated, and note that the experiment will continue to run through 2020 with NSF support. The major conclusions of the study to date are: (1 Elevated CO2 stimulated plant productivity in the C3 plant community by ~30% during the 25 year study. The magnitude of the increase in productivity varied interannually and was sometime absent altogether. There is some evidence of down-regulation at the ecosystem level across the 25 year record that may be due to interactions with other factors such as sea-level rise or long-term changes in N supply; (2) Elevated CO2 stimulated C4 productivity by <10%, perhaps due to more efficient water use, but C3 plants at elevated CO2 did not displace C4 plants as predicted; (3) Increased primary production caused a general stimulation of microbial processes, but there were both increases and decreases in activity depending on the specific organisms considered. An increase in methanogenesis and methane emissions implies elevated CO2 may amplify radiative forcing in the case of wetland ecosystems; (4) Elevated CO2 stimulated soil carbon sequestration in the form of an increase in elevation. The increase in elevation is 50-100% of the increase in net ecosystem production caused by elevated CO2 (still under analysis). The increase in soil elevation suggests the elevated CO2 may have a positive outcome for the ability of coastal wetlands to persist despite accelerated sea level rise; (5) Crossing elevated CO2 with elevated N causes the elevated CO2 effect to diminish, with consequences for change in soil elevation.

More than half of the electricity currently generated in the United States comes from coal-fired boilers, and there is little indication that this percentage will diminish through 2020 and beyond. In addition, the use of coal for electricity generation is projected to more than double in developing nations by 2020. This ever growing demand for fossil-fuel-based power and the consequential rise in atmospheric carbon dioxide (CO 2 ) concentrations requires innovative methods to capture and store CO 2 .

3D Corporate Tourism in the Marine Sciences: Application-Oriented Problem Solving in Marine and Coastal Ecosystems  

E-Print Network (OSTI)

3D corporate tourism in the marine sciences is a solution-based approach to innovation in science, engineering and design. Corporate international scientists, engineers and designers work with local experts in Malaysian marine and coastal environments: they jointly discover, develop and design complex materials and designs inspired by nature directly on site (e.g. at the UKM Marine Ecosystem Research Centre EKOMAR and Malaysian Marine Parks) and construct initial biomimetic prototypes and novel designs. Thereby, new links, networks and collaborations are established between communities of thinkers in different countries. 3D tourism aims at mapping new frontiers in emerging engineering and design fields. This provides a novel way to foster and promote innovative thinking in the sciences, and considers the need for synergy and collaboration between marine sciences, engineering and design rather than segmentation and isolation. With the concept of 3D corporate tourism the potential of Malaysian marine ecosystems...

RADIATION DOSE ASSESSMENT FOR THE BIOTA OF TERRESTRIAL ECOSYSTEMS IN THE SHORELINE ZONE OF THE CHERNOBYL NUCLEAR POWER PLANT COOLING POND  

SciTech Connect

Radiation exposure of the biota in the shoreline area of the Chernobyl Nuclear Power Plant Cooling Pond was assessed to evaluate radiological consequences from the decommissioning of the Cooling Pond. The article addresses studies of radioactive contamination of the terrestrial faunal complex and radionuclide concentration ratios in bodies of small birds, small mammals, amphibians, and reptiles living in the area. The data were used to calculate doses to biota using the ERICA Tool software. Doses from {sup 90}Sr and {sup 137}Cs were calculated using the default parameters of the ERICA Tool and were shown to be consistent with biota doses calculated from the field data. However, the ERICA dose calculations for plutonium isotopes were much higher (2-5 times for small mammals and 10-14 times for birds) than the doses calculated using the experimental data. Currently, the total doses for the terrestrial biota do not exceed maximum recommended levels. However, if the Cooling Pond is allowed to drawdown naturally and the contaminants of the bottom sediments are exposed and enter the biological cycle, the calculated doses to biota may exceed the maximum recommended values. The study is important in establishing the current exposure conditions such that a baseline exists from which changes can be documented following the lowering of the reservoir water. Additionally, the study provided useful radioecological data on biota concentration ratios for some species that are poorly represented in the literature.

ECOSYSTEM IMPACTS OF GEOENGINEERING: A Review for Developing a Science Plan  

SciTech Connect

Geoengineering methods are intended to reduce the magnitude of climate change. Climate change in some regions is already having demonstrable effects on ecosystem structure and functioning. Two different types of geoengineering activities have been proposed: carbon dioxide removal (CDR), which includes a range of engineered and biological processes to remove carbon dioxide (CO2) from the atmosphere, and solar radiation management (SRM, or sunlight reflection methods), whereby a small percentage of sunlight is reflected back into space to offset warming from greenhouse gases. In this review, we evaluate some of the possible impacts of CDR and SRM on the physical climate and their subsequent influence on ecosystems, including the risks and uncertainties associated with new kinds of purposeful perturbations to Earth. Specifically, we find evidence that, if implemented successfully, some CDR methods and continue use of some SRM methods) could alleviate some of the deleterious ecosystem impacts associated with climate changes that might occur in the foreseeable future.

Planning the Next Generation of Arctic Ecosystem Experiments  

SciTech Connect

Climate Change Experiments in High-Latitude Ecosystems; Fairbanks, Alaska, 13-14 October 2010; A 2-day climate change workshop was held at the International Arctic Research Center, University of Alaska Fairbanks. The workshop, sponsored by Biological and Environmental Research, Office of Science, U.S. Department of Energy (DOE), was attended by 45 subject matter experts from universities, DOE national laboratories, and other federal and nongovernmental organizations. The workshop sought to engage the Arctic science community in planning for a proposed Next-Generation Ecosystem Experiments (NGEE-Arctic) project in Alaska (http:// ngee.ornl.gov/). The goal of this activity is to provide data, theory, and models to improve representations of high-latitude terrestrial processes in Earth system models. In particular, there is a need to better understand the processes by which warming may drive increased plant productivity and atmospheric carbon uptake and storage in biomass and soils, as well as those processes that may drive an increase in the release of methane (CH{sub 4}) and carbon dioxide (CO{sub 2}) through microbial decomposition of soil carbon stored in thawing permafrost. This understanding is required to quantify the important feedback mechanisms that define the role of terrestrial processes in regional and global climate.

Fire and aquatic ecosystems of the western USA: current knowledge and key questions  

Science Journals Connector (OSTI)

Understanding of the effects of wildland fire and fire management on aquatic and riparian ecosystems is an evolving field, with many questions still to be resolved. Limitations of current knowledge, and the certainty that fire management will continue, underscore the need to summarize available information. Integrating fire and fuels management with aquatic ecosystem conservation begins with recognizing that terrestrial and aquatic ecosystems are linked and dynamic, and that fire can play a critical role in maintaining aquatic ecological diversity. To protect aquatic ecosystems we argue that it will be important to: (1) accommodate fire-related and other ecological processes that maintain aquatic habitats and biodiversity, and not simply control fires or fuels; (2) prioritize projects according to risks and opportunities for fire control and the protection of aquatic ecosystems; and (3) develop new consistency in the management and regulatory process. Ultimately, all natural resource management is uncertain; the role of science is to apply experimental design and hypothesis testing to management applications that affect fire and aquatic ecosystems. Policy-makers and the public will benefit from an expanded appreciation of fire ecology that enables them to implement watershed management projects as experiments with hypothesized outcomes, adequate controls, and replication.

Global Change and the Terrestrial Biosphere (449th Brookhaven Lecture)  

SciTech Connect

Since the Industrial Revolution, the increased use of fossil fuels has resulted in a dramatic and unprecedented rise in the concentration of atmospheric carbon dioxide. Most scientists agree that increasing levels of carbon dioxide and other greenhouse gases have raised Earth's temperature and, without a reduction in emissions, will continue to do so. Terrestrial ecosystems sustain life on Earth through the production of food, fuel, fiber, clean air, and naturally purified water. But how will agriculture and ecosystems be affected by global change? Rogers will describe the impact of projected climate change on the terrestrial biosphere and explain why plants are not just passive respondents to global change, but play an important role in determining the rate of change.

Trends and Future Challenges in Sampling the Deep Terrestrial Biosphere  

SciTech Connect

Research in the deep terrestrial biosphere is driven by interest in novel biodiversity and metabolisms, biogeochemical cycling, and the impact of human activities on this ecosystem. As this interest continues to grow, it is important to ensure that when subsurface investigations are proposed, materials recovered from the subsurface are sampled and preserved in an appropriate manner to limit contamination and ensure preservation of accurate microbial, geochemical, and mineralogical signatures. On February 20th, 2014, a workshop on Trends and Future Challenges in Sampling The Deep Subsurface was coordinated in Columbus, Ohio by The Ohio State University and West Virginia University faculty, and sponsored by The Ohio State University and the Sloan Foundations Deep Carbon Observatory. The workshop aims were to identify and develop best practices for the collection, preservation, and analysis of terrestrial deep rock samples. This document summarizes the information shared during this workshop.

The water management plan aimed to reduce SESD's potable water usage (more than 2.4 million gallons in fiscal year 2008) through an air handler condensate recovery project. The EPA SESD encompasses 12 acres in Athens, Georgia. A single laboratory building was constructed in 1996 consisting of 66,200 square feet configured for a mix use of laboratory and office activities. In May 2008, SESD completed an air handler condensate recovery system. The system routes condensate from rooftop air handler units to the facility's cooling tower,

Chapter 6 - Ecosystem Services  

Science Journals Connector (OSTI)

Abstract Forested ecosystems have always provided a large suite of services that benefit human civilizations, animals, plants, and other organisms living within the Earths biosphere. As suggested in earlier chapters, forested ecosystems generate numerous provisioning, regulating, supporting, and cultural services. These services provide the basic building blocks of life on Earth and for human civilizations. Unfortunately, at times humans neither understand nor appreciate the regulating or supporting functions provided by ecosystems. Maintaining the health and well-being of our forested ecosystems can improve human health concerns and protect our homes from unexpected events such as floods and wildfires. Many also argue that healthy ecosystems are the foundation upon which we can build a secure future for our children and grandchildren. Managers of forests and natural resources will undoubtedly face trade-offs among ecosystem services when considering their actions. Even deciding to do nothing at all will involve the analysis of trade-offs, since some of the services provided by ecosystems include the food, shelter, and materials we may use in our normal, daily lives.

Relative importance of multiple factors on terrestrial loading of DOC to Arctic river networks  

SciTech Connect

Terrestrial carbon dynamics influence the contribution of dissolved organic carbon (DOC) to river networks in addition to controlling carbon fluxes between the land surface and the atmosphere. In this study, we use a biogeochemical process model to simulate the lateral transfer of DOC from land to the Arctic Ocean via riverine transport. We estimate that the pan-arctic watershed has contributed, on average, 32 Tg C/yr of DOC to the Arctic Ocean over the 20th century with most coming from the extensive area of boreal deciduous needle-leaved forests and forested wetlands in Eurasian watersheds. We also estimate that the rate of terrestrial DOC loading has been increasing by 0.037 Tg C/yr2 over the 20th century primarily as a result of increases in air temperatures and precipitation. These increases have been partially compensated by decreases in terrestrial DOC loading caused by wildfires. Other environmental factors (CO2 fertilization, ozone pollution, atmospheric nitrogen deposition, timber harvest, agriculture) are estimated to have relatively small effects on terrestrial DOC loading to arctic rivers. The effects of the various environmental factors on terrestrial carbon dynamics have both compensated and enhanced concurrent effects on hydrology to influence terrestrial DOC loading. Future increases in riverine DOC concentrations and export may occur from warming-induced increases in terrestrial DOC production associated with enhanced microbial metabolism and the exposure of additional organic matter from permafrost degradation along with decreases in water yield associated with warming-induced increases in evapotranspiration. Improvements in simulating terrestrial DOC loading to pan-arctic rivers in the future will require better information on the spatial distribution of precipitation and its temporal trends, carbon dynamics of larch-dominated ecosystems in eastern Siberia, and the role of industrial organic effluents on carbon budgets of rivers in western Russia.

Science  

Science Journals Connector (OSTI)

As a self-confessed purveyor of ``frequently outrageous views,'' Steve Fuller can be relied on for a spirited and provocative text - and so this proves. Jerry Ravetz's gushing endorsement on the back cover claims that the public's understanding of science ``will never be the same again'' and that the book proves Steve Fuller to be ``actually science's best friend.'' But those of an orthodox scientific persuasion (though perhaps not his intended audience) are likely to be provoked into dyspeptic displeasure by the first few sideswipes at what they hold most dear. This short text comprises one volume of the series `` Concepts in Social Science,'' in publishing order sandwiched between Rights and Liberalism. Its expressed aim is that the reader come away thinking ``that the idea and institution of `science' go to the very heart of what the social sciences are about.'' In a style that is always inspired but for all save the cognoscenti can sometimes verge on the abstruse, Fuller argues that social and scientific realities are inextricably intertwined. Science's implausible knowledge claims of detachment and objectivity succeed only in perpetuating self-delusion, sowing the seeds for science's own demise. For those familiar with the sociology of scientific knowledge (SSK) debates, the overall message will not be entirely new - and indeed the book is in part a reworking of some of Fuller's previously-published journal articles - but the liveliness of this contentious prose and its immodest, sweeping polemical style present a critical case against science that is often uncomfortably near the bone. What is impressive is Fuller's intellectual boldness in weaving together a wealth of sociological, philosophical and historical arguments that aim to reveal for public scrutiny the true nature of science. The picture of science created is of its frailty and everydayness - qualities that Fuller claims have been disguised by an unattractive mix of intellectual cunning and social naivet from scientists. Fuller portrays a lay public that combines insight and innocence. Sometimes the public can see through science's ploys for extravagant research proposals, thereby ``displaying a fundamentally sound instinctive response to science.'' At other times, the public is foolish enough to regard scientific knowledge as distinct and authoritative - ``reliable'' lay beliefs about science he says are sadly rare. Thus, in Fuller's eyes, misunderstandings of science abound. Whereas some critics see the yearly panjandrum that constitutes Science Weeks as a clumsy and politically naive stab at ``public relations,'' Fuller sees darker forces of ignorance at work - ``evidence of the scientific community misunderstanding something significant about the social conditions that enable its existence.'' Tackling the public understanding of science (PUS) debate in such a spirit in Chapter 1 sets the tone for the protracted dissection of science that follows. But Fuller's aim is more to do with the revelation of sociological phenomena than with ridicule of science. For example, in Chapter 2 the idiosyncrasies of particular scientific disciplines are picked apart (in the best sociological tradition, physics comes in for a good deal of epistemological stick). Fuller succeeds in portraying the various branches of science as fundamentally different, with distinct working practices shaped by different histories and presumptions. Why, the author then muses, are interdisciplinary wars within science rare, in contrast to social science? With such questions to crack, science is rich pickings for sociological inquiry. In Chapter 3, Fuller's concern is the many-layered meanings of the terms science, scientific and scientists. Here the author takes us through the sociological and philosophical twists and turns of meaning with ideological ease, neatly contrasting today's science with that of the past. For example, long gone is science's unquestioned claim always to serve the best interest of the state; now science is self-serving. Much missed too is science's ability to stab

SciTech Connect

The 1992 Annual Report from Pacific Northwest Laboratory (PNL) to the US Department of Energy (DOE) describes research in environment and health conducted during fiscal year 1992. This report consists of four volumes oriented to particular segments of the PNL program, describing research performed for the DOE Office of Health and Environmental Research in the Office of Energy Research. The parts of the 1992 Annual Report are: Biomedical Sciences; Environmental Sciences; Atmospheric Sciences; and Physical Sciences. This Report is Part 2: Environmental Sciences. Included in this report are developments in Subsurface Science, Terrestrial Science, Laboratory-Directed Research and Development, Interactions with Educational Institutions, Technology Transfer, Publications, and Presentations. The research is directed toward developing a fundamental understanding of subsurface and terrestrial systems as a basis for both managing these critical resources and addressing environmental problems such as environmental restoration and global change. The Technology Transfer section of this report describes a number of examples in which fundamental research is laying the groundwork for the technology needed to resolve important environmental problems. The Interactions with Educational Institutions section of the report illustrates the results of a long-term, proactive program to make PNL facilities available for university and preuniversity education and to involve educational institutions in research programs. The areas under investigation include the effect of geochemical and physical phenomena on the diversity and function of microorganisms in deep subsurface environments, ways to address subsurface heterogeneity, and ways to determine the key biochemical and physiological pathways (and DNA markers) that control nutrient, water, and energy dynamics in arid ecosystems and the response of these systems to disturbance and climatic change.

Carbon Isotopic Studies of Assimilated and Ecosystem Respired CO2 in a Southeastern Pine Forest  

SciTech Connect

Carbon dioxide is the major greenhouse gas responsible for global warming. Southeastern pine forests appear to be among the largest terrestrial sinks of carbon dioxide in the US. This collaborative study specifically addressed the isotopic signatures of the large fluxes of carbon taken up by photosynthesis and given off by respiration in this ecosystem. By measuring these isotopic signatures at the ecosystem level, we have provided data that will help to more accurately quantify the magnitude of carbon fluxes on the regional scale and how these fluxes vary in response to climatic parameters such as rainfall and air temperature. The focus of the MBL subcontract was to evaluate how processes operating at the physiological and ecosystem scales affects the resultant isotopic signature of plant waxes that are emitted as aerosols into the convective boundary layer. These wax aerosols provide a large-spatial scale integrative signal of isotopic discrimination of atmospheric carbon dioxide by terrestrial photosynthesis (Conte and Weber 2002). The ecosystem studies have greatly expanded of knowledge of wax biosynthetic controls on their isootpic signature The wax aerosol data products produced under this grant are directly applicable as input for global carbon modeling studies that use variations in the concentration and carbon isotopic composition of atmospheric carbon dioxide to quantify the magnitude and spatial and temporal patterns of carbon uptake on the global scale.

A global analysis of soil microbial biomass carbon, nitrogen and phosphorus in terrestrial ecosystems  

SciTech Connect

Soil microbes play a pivotal role in regulating land-atmosphere interactions; the soil microbial biomass carbon (C), nitrogen (N), phosphorus (P) and C:N:P stoichiometry are important regulators for soil biogeochemical processes; however, the current knowledge on magnitude, stoichiometry, storage, and spatial distribution of global soil microbial biomass C, N, and P is limited. In this study, 3087 pairs of data points were retrieved from 281 published papers and further used to summarize the magnitudes and stoichiometries of C, N, and P in soils and soil microbial biomass at global- and biome-levels. Finally, global stock and spatial distribution of microbial biomass C and N in 0-30 cm and 0-100 cm soil profiles were estimated. The results show that C, N, and P in soils and soil microbial biomass vary substantially across biomes; the fractions of soil nutrient C, N, and P in soil microbial biomass are 1.6% in a 95% confidence interval of (1.5%-1.6%), 2.9% in a 95% confidence interval of (2.8%-3.0%), and 4.4% in a 95% confidence interval of (3.9%-5.0%), respectively. The best estimates of C:N:P stoichiometries for soil nutrients and soil microbial biomass are 153:11:1, and 47:6:1, respectively, at global scale, and they vary in a wide range among biomes. Vertical distribution of soil microbial biomass follows the distribution of roots up to 1 m depth. The global stock of soil microbial biomass C and N were estimated to be 15.2 Pg C and 2.3 Pg N in the 0-30 cm soil profiles, and 21.2 Pg C and 3.2 Pg N in the 0-100 cm soil profiles. We did not estimate P in soil microbial biomass due to data shortage and insignificant correlation with soil total P and climate variables. The spatial patterns of soil microbial biomass C and N were consistent with those of soil organic C and total N, i.e. high density in northern high latitude, and low density in low latitudes and southern hemisphere.

Terrestrial biogeochemical feedbacks in the climate system: from past to future  

SciTech Connect

The terrestrial biosphere plays a major role in the regulation of atmospheric composition, and hence climate, through multiple interlinked biogeochemical cycles (BGC). Ice-core and other palaeoenvironmental records show a fast response of vegetation cover and exchanges with the atmosphere to past climate change, although the phasing of these responses reflects spatial patterning and complex interactions between individual biospheric feedbacks. Modern observations show a similar responsiveness of terrestrial biogeochemical cycles to anthropogenically-forced climate changes and air pollution, with equally complex feedbacks. For future conditions, although carbon cycle-climate interactions have been a major focus, other BGC feedbacks could be as important in modulating climate changes. The additional radiative forcing from terrestrial BGC feedbacks other than those conventionally attributed to the carbon cycle is in the range of 0.6 to 1.6 Wm{sup -2}; all taken together we estimate a possible maximum of around 3 Wm{sup -2} towards the end of the 21st century. There are large uncertainties associated with these estimates but, given that the majority of BGC feedbacks result in a positive forcing because of the fundamental link between metabolic stimulation and increasing temperature, improved quantification of these feedbacks and their incorporation in earth system models is necessary in order to develop coherent plans to manage ecosystems for climate mitigation.

Adaptive management of coastal ecosystem restoration projects  

Science Journals Connector (OSTI)

There is a clear need to apply better and more effective management schemes to coastal ecosystem restoration projects. It is very common for aquatic ecosystem restoration projects not to meet their goals. Poor performance has led to a high degree of uncertainty about the potential success of any restoration effort. Under adaptive management, the knowledge gained through monitoring of the project and social policies is translated into restoration policy and program redesign. Planners and managers can utilize the information from the monitoring programs in an effective way to assure that project goals are met or that informed and objective decisions are made to address both ecological and societal needs. The three main ingredients of an effective adaptive management plan in a restoration project are: (1) a clear goal statement; (2) a conceptual model; and (3) a decision framework. The goal drives the design of the project and helps guide the development of performance criteria. The goal statement and performance criteria provide the means by which the system can be judged. With the conceptual model, the knowledge base from the field of ecological science plays an active and critical role in designing the project to meet the goal. A system-development matrix provides a simple decision framework to view the alternative states for the system during development, incorporate knowledge gained through the monitoring program, and formulate a decision on actions to take if the system is not meeting its goal.

Ecotoxicology of tropical marine ecosystems  

SciTech Connect

The negative effects of chemical contaminants on tropical marine ecosystems are of increasing concern as human populations expand adjacent to these communities. Watershed streams and ground water carry a variety of chemicals from agricultural, industrial, and domestic activities, while winds and currents transport pollutants from atmospheric and oceanic sources to these coastal ecosystems. The implications of the limited information available on impacts of chemical stressors on mangrove forests, seagrass meadows, and coral reefs are discussed in the context of ecosystem management and ecological risk assessment. Three classes of pollutants have received attention: heavy metals, petroleum, and synthetic organics. Heavy metals have been detected in all three ecosystems, causing physiological stress, reduced reproductive success, and outright mortality in associated invertebrates and fishes. Oil spills have been responsible for the destruction of entire coastal shallow-water communities, with recovery requiring years. Herbicides are particularly detrimental to mangroves and seagrasses and adversely affect the animal-algal symbioses in corals. Pesticides interfere with chemical cues responsible for key biological processes, including reproduction and recruitment of a variety of organisms. Information is lacking with regard to long-term recovery, indicator species, and biomarkers for tropical communities. Critical areas that are beginning to be addressed include the development of appropriate benchmarks for risk assessment, baseline monitoring criteria, and effective management strategies to protect tropical marine ecosystems in the face of mounting anthropogenic disturbance.

CARBONATE STABLE ISOTOPES | Terrestrial Teeth and Bones  

Science Journals Connector (OSTI)

Teeth and bones of fossil vertebrates can preserve a record of Quaternary terrestrial environments in the form of isotopic compositions of carbon (13C/12C), nitrogen (15N/14N), and oxygen (18O/16O). These isotopic signatures in teeth and bones have yielded valuable information on the extent of savanna environments under tropical climates, on the ancient levels of aridity, on the spread of dense forests at the beginning of the Holocene, and on the paleodiet of hominids and their associated fauna.

The distribution and biomagnification of higher brominated \\{BDEs\\} in terrestrial organisms affected by a typical e-waste burning site in South China  

Science Journals Connector (OSTI)

Abstract Soil, vegetation, and several terrestrial species including turtledove, chicken, goose, grasshopper, dragonfly, butterfly and ant, were collected from an area surrounding a typical e-waste burning site in South China. The samples were examined to investigate the levels, congener profiles, and biomagnification extent of polybrominated diphenyl ethers (PBDEs) that may be present in the environment as a result of the e-waste, which was processed in a crude recycling style. Elevated levels of ?21PBDEs were found in the biota (1014725ngg?1 lipid weight (lw)), vegetation leaf (82.9319ngg?1 dry weight (dw)) and soil samples (5.222110ngg?1 dw), indicating that PBDE contamination in the samples collected from the e-waste burning site may pose risks to the local terrestrial ecosystem and local populations. Higher BDE congeners, especially deca-BDE (BDE-209) were the dominant homologs in organisms and nonbiological matrices, followed by nona-BDE and octa-BDE. Biomagnification factors (BMFs) were calculated as the ratio of the lipid-normalized concentration in the predator to that in the prey. The highest BMF (3.4) was determined for BDE-153 in the grasshopper/turtledove food chain. Other higher brominated congeners, such as BDE-202, -203, -154, -183 and -209, were also biomagnified in the terrestrial food chain with \\{BMFs\\} of 1.73.3. BDE-47, -100, and -99 were not biomagnified in the examined food chains (BMFs<1), which suggests that bioaccumulation and biotransformation of \\{PBDEs\\} in terrestrial ecosystems could be distinguished from those in aquatic ecosystems.

Fuel cells for extraterrestrial and terrestrial applications  

SciTech Connect

The fuel cell is a nineteenth century invention and a twentieth century technology development. Due to the high power and energy density, high efficiency, reliability, and production of pure water, hydrogen-oxygen fuel cell systems have no competition as auxiliary power sources for space vehicles. The alkaline fuel cell system is a well developed and proven technology for this application. The solid polymer electrolyte system may be its future competitor. The energy crisis of 1973 stimulated research, development and demonstration of the phosphoric acid, molten carbonate, solid oxide and solid polymer electrolyte fuel cell systems using natural gas, petroleum or coal derived hydrogen (and carbon monoxide for the high temperature systems) for terrestrial applications. The direct methanol-air fuel cell is still an electrochemist's dream. Though considerable technological advances have been made, the present price of crude oil, and the high capital costs and limited lifetime of fuel cell systems impede their terrestrial applications in the developed countries. Conversely, the potential for lower capital costs of labor intensive manufacturing processes and the relatively higher fossil fuel prices make these systems more attractive for such applications in the developing countries. 11 refs.

Definition, Capabilities, and Components of a Terrestrial Carbon Monitoring System  

SciTech Connect

Research efforts for effectively and consistently monitoring terrestrial carbon are increasing in number. As such, there is a need to define carbon monitoring and how it relates to carbon cycle science and carbon management. There is also a need to identify intended capabilities of a carbon monitoring system and what system components are needed to develop the capabilities. This paper is intended to promote discussion on what capabilities are needed in a carbon monitoring system based on requirements for different areas of carbon-related research and, ultimately, for carbon management. While many methods exist to quantify different components of the carbon cycle, research is needed on how these methods can be coupled or integrated to obtain carbon stock and flux estimates regularly and at a resolution that enables attribution of carbon dynamics to respective sources. As society faces sustainability and climate change conerns, carbon management activities implemented to reduce carbon emissions or increase carbon stocks will become increasingly important. Carbon management requires moderate to high resolution monitoring. Therefore, if monitoring is intended to help inform management decisions, management priorities should be considered prior to development of a monitoring system.

Solar magnetic fields and terrestrial climate  

E-Print Network (OSTI)

Solar irradiance is considered one of the main natural factors affecting terrestrial climate, and its variations are included in most numerical models estimating the effects of natural versus anthropogenic factors for climate change. Solar wind causing geomagnetic disturbances is another solar activity agent whose role in climate change is not yet fully estimated but is a subject of intense research. For the purposes of climate modeling, it is essential to evaluate both the past and the future variations of solar irradiance and geomagnetic activity which are ultimately due to the variations of solar magnetic fields. Direct measurements of solar magnetic fields are available for a limited period, but can be reconstructed from geomagnetic activity records. Here we present a reconstruction of total solar irradiance based on geomagnetic data, and a forecast of the future irradiance and geomagnetic activity relevant for the expected climate change.

Astrometric Detection of Terrestrial Planets in the Habitable Zones of Nearby Stars with SIM PlanetQuest  

E-Print Network (OSTI)

SIM PlanetQuest (Space Interferometry Mission) is a space-borne Michelson interferometer for precision stellar astrometry, with a nine meter baseline, currently slated for launch in 2015. One of the principal science goals is the astrometric detection and orbit characterization of terrestrial planets in the habitable zones of nearby stars. Differential astrometry of the target star against a set of reference stars lying within a degree will allow measurement of the target star's reflex motion with astrometric accuracy of 1 micro-arcsecond in a single measurement. We assess SIM's capability for detection (as opposed to characterization by orbit determination) of terrestrial planets in the habitable zones of nearby solar-type stars. We compare SIM's performance on target lists optimized for the SIM and Terrestrial Planet Finder Coronograph (TPF-C) missions. Performance is quantified by three metrics: minimum detectable planet mass, number and mass distribution of detected planets, and completeness of detections in each mass range. Finally, we discuss the issue of confidence in detections and non-detections, and show how information from SIM's planet survey can enable TPF to increase its yield of terrestrial planets.

Mapping cultural ecosystem services: A framework to assess the potential for outdoor recreation across the EU  

Science Journals Connector (OSTI)

Abstract Research on ecosystem services mapping and valuing has increased significantly in recent years. However, compared to provisioning and regulating services, cultural ecosystem services have not yet been fully integrated into operational frameworks. One reason for this is that transdisciplinarity is required to address the issue, since by definition cultural services (encompassing physical, intellectual, spiritual interactions with biota) need to be analysed from multiple perspectives (i.e. ecological, social, behavioural). A second reason is the lack of data for large-scale assessments, as detailed surveys are a main source of information. Among cultural ecosystem services, assessment of outdoor recreation can be based on a large pool of literature developed mostly in social and medical science, and landscape and ecology studies. This paper presents a methodology to include recreation in the conceptual framework for EU wide ecosystem assessments (Maes et al., 2013), which couples existing approaches for recreation management at country level with behavioural data derived from surveys and population distribution data. The proposed framework is based on three components: the ecosystem function (recreation potential), the adaptation of the Recreation Opportunity Spectrum framework to characterise the ecosystem service and the distribution of potential demand in the EU. Results show that 38% of the EU is characterised by a high outdoor recreation potential, which is easily accessible, and that such areas can host about 35.4% of potential demand for close-to-home trips (recreation potential as an ecosystem service to EU citizens, to describe through country profiles differences in ecosystem service provision at regional level, and can be used as an input to land use planning processes.

Isotope powered Stirling generator for terrestrial applications  

SciTech Connect

An electric power supply, small enough to be man-portable, is being developed for remote, terrestrial applications. This system is designed for an operating lifetime of five years without maintenance or refueling. A small Radioisotope Stirling Generator (RSG) has been developed. The energy source of the generator is a 60 watt plutonium-238 fuel clad used in the General Purpose Heat Sources (GPHS) developed for space applications. A free piston Stirling Engine drives a linear alternator to convert the heat to power. The system weighs about 7.5 kg and produces 11 watts AC power with a conversion efficiency of 18.5%. Two engine models have been designed, fabricated, and tested to date: (a) a developmental model instrumented to confirm and test parameters, and (b) an electrically heated model with an electrical heater equipped power input leads. Critical components have been tested for 10,000 to 20,000 hours. One complete generator has been operating for over 11,000 hours. Radioisotope heated prototypes are expected to be fabricated and tested in late 1995.

The project yielded papers on fluxes (energy, water and carbon dioxide)between each ecosystem and the atmosphere, and explained the temporal dynamics of fluxes based on intrinsic (physiology, canopy leaf area and structure) and extrinsic (atmospheric and edaphic conditions). Comparisons between any two of the ecosystems, and among all three followed, attributing differences in behavior to different patterns of phenology and differential sensitivities to soil and atmospheric humidity. Finally, data from one-to-three of the ecosystems (incorporated into FluxNet data archive) were used in syntheses across AmeriFlux sites and even more broadly across FluxNet sites.

Evaluating the Contribution of Climate Forcing and Forest Dynamics to Accelerating Carbon Sequestration by Forest Ecosystems in the Northeastern U.S.: Final Report  

SciTech Connect

This report summarizes work to improve quantitative understanding of the terrestrial ecosystem processes that control carbon sequestration in unmanaged forests It builds upon the comprehensive long-term observations of CO2 fluxes, climate and forest structure and function at the Harvard Forest in Petersham, MA. This record includes the longest CO2 flux time series in the world. The site is a keystone for the AmeriFlux network. Project Description The project synthesizes observations made at the Harvard Forest HFEMS and Hemlock towers, which represent the dominant mixed deciduous and coniferous forest types in the northeastern United States. The 20+ year record of carbon uptake at Harvard Forest and the associated comprehensive meteorological and biometric data, comprise one of the best data sets to challenge ecosystem models on time scales spanning hourly, daily, monthly, interannual and multi-decadal intervals, as needed to understand ecosystem change and climate feedbacks.

Digital Ecosystems: Evolving Service-Orientated Architectures  

E-Print Network (OSTI)

A novel optimisation technique inspired by natural ecosystems is presented, where the optimisation works at two levels: a first optimisation, migration of services which are distributed in a decentralised peer-to-peer network, operating continuously in time; this process feeds a second optimisation based on evolutionary computing that operates locally on single peers and is aimed at finding solutions to satisfy locally relevant constraints. Through this twofold process, the local search is accelerated and will yield better local optima, because the distributed optimisation already provides a good sampling of the search space by making use of computations already performed in other peers with similar constraints. We call this new distributed optimisation architecture a Digital Ecosystem, an Ecosystem Orientated Architecture (EOA) created by extending a Service-Oriented Architecture (SOA) with Distributed Evolutionary Computing (DEC). The Digital Ecosystem will allow services to recombine and evolve over time, ...

Radionuclides in the terrestrial ecosystem near a Canadian uranium mill -- Part 3: Atmospheric deposition rates (pilot test)  

SciTech Connect

Atmospheric deposition rates of uranium series radionuclides were directly measured at three sites near the operating Key Lake uranium mill in northern Saskatchewan. Sites impacted by windblown tailings and mill dusts had elevated rates of uranium deposition near the mill and elevated {sup 226}Ra deposition near the tailings compared to a control site. Rainwater collectors, dust jars, and passive vinyl collectors previously used at the Ranger Mine in Australia were pilot-tested. Adhesive vinyl surfaces (1 m{sup 2}) were oriented horizontally, vertically, and facing the ground as a means of measuring gravitational settling, wind impaction, and soil resuspension, respectively. Although the adhesive glue on the vinyls proved difficult to digest, relative differences in deposition mode were found among radionuclides and among sites. Dry deposition was a more important transport mechanism for uranium, {sup 226}Ra, and {sup 210}Pb than rainfall, while more {sup 210}Po was deposited with rainfall.

Integrated environmental monitoring at remote ecosystems  

SciTech Connect

The first annual report reviews progress to date on the Idaho National Engineering Laboratory(INEL) research project, Integrated Ecosystem and Pollutant Monitoring at Remote Wilderness Study Sites.'' The two primary objectives of this study are to apply, field test, and conceptually evaluate the US Forest Service guidelines for remote ecosystem monitoring and to provide an ongoing database on selected high-elevation ecosystem attributes, including physical, chemical, and biological parameters. The basic criteria for evaluation of the guidelines are usability, cost-effectiveness, data variability, alternative approaches, ecosystem conceptual approach, and quality assurance. The goal of the project is to identify a list of pollutant measurements and ecological attributes that will provide good, quality-assured data about a particular ecosystem. The present report covers each of the major components of the Forest Service guidelines except for regulatory and management constraints and visibility, which are not part of this project. Therefore, progress to date is provided as separate sections of the report for each of the following components: atomspheric environment, soils, aquatic chemistry, aquatic biology, salmonid fish, and plants (including forest ecosystem). 24 refs., 66 figs., 28 tabs.

Evaluation of terrestrial microcosms for assessing the fate and effects of genetically engineered microorganisms on ecological processes  

SciTech Connect

This project evaluates and modifies the existing US Environmental Protection Agency's Office of Pesticides and Toxic Substances (EPA/OPTS) terrestrial microcosm test system and test protocols such that they can be used to determine the environmental fate and ecological hazards of genetically engineered microorganisms (GEMs). The intact soil-core microcosm represents terrestrial ecosystems, and when coupled with appropriate test protocols, such microcosms may be appropriate to define and limit risks associated with the intentional release of GEMs. The terrestrial microcosm test system was used to investigate the survival and transport of two model GEMs (Azospirillum lipoferum and Pseudomonas sp. Tn5 mutants) to various trophic levels and niches and through intact soil cores. Subsequent effects on nutrient cycling and displacement of indigenous microorganisms were evaluated. The model organisms were a diazotrophic root-colonizing bacterium (A. lipoferum) and a wheat root growth-inhibiting rhizobacterium (Pseudomonas sp.). The transposable element Tn5 was used as a genetic marker for both microorganisms in two separate experiments. The organisms were subjected to transposon mutagenesis using a broad host-range-mobilizable suicide plasmid. The transposon Tn5 conferred levels of kanamycin resistance up to 500 ..mu..g/ml (Pseudomonas sp.), which allowed for selection of the bacteria from environmental samples. The presence of Tn5 DNA in the genome of the model GEMs also allowed the use of Tn5 gene probes to confirm and enumerate the microorganisms in different samples from the microcosms. Two types of root growth-inhibiting Pseudomonas sp. Tn5 mutants were obtained and used in microcosm studies: those that lacked the ability to inhibit either wheat root growth or the growth of other microorganisms in vitro (tox/sup /minus//) and those which retained these properties (tox/sup +/). 53 refs., 7 figs., 6 tabs.

Estimation of radiation doses from 137Cs to frogs in a wetland ecosystem  

Science Journals Connector (OSTI)

Currently, there is no established methodology to estimate radiation doses to non-human biota. Therefore, in this study, various dose models were used to estimate radiation doses to moor frogs (Rana arvalis) in a wetland ecosystem contaminated with 137Cs. External dose estimations were based on activity concentrations of 137Cs in soil and water, considering changes in habitat over a life-cycle. Internal doses were calculated from the activity concentrations of 137Cs measured in moor frogs. Depending on the dose model used, the results varied substantially. External dose rates ranged from 21 to 160 mGy/y, and internal dose rates varied between 1 and 14 mGy/y. Maximum total dose rates to frogs were below the expected safe level for terrestrial populations, but close to the suggested critical dose rate for amphibians. The results show that realistic assumptions in dose models are particularly important at high levels of contamination.

For example, vegetation management is a significant and growing component of annual maintenance costs at legacy sites. Long-term surveillance plans often require suppression of plant growth on rock-covered disposal cells because scientists have concerns that (1) plants' roots may increase water percolation through compacted soil layers into buried contaminated material (and hence, increase the potential for spreading contamination), or (2) roots may take up and disperse buried contaminants (e.g., wind may spread contaminated plant materials or

Building sustainable ecosystem-oriented architectures  

E-Print Network (OSTI)

Currently, organizations are transforming their business processes into e-services and service-oriented architectures to improve coordination across sales, marketing, and partner channels, to build flexible and scalable systems, and to reduce integration-related maintenance and development costs. However, this new paradigm is still fragile and lacks many features crucial for building sustainable and progressive computing infrastructures able to rapidly respond and adapt to the always-changing market and environmental business. This paper proposes a novel framework for building sustainable Ecosystem- Oriented Architectures (EOA) using e-service models. The backbone of this framework is an ecosystem layer comprising several computing units whose aim is to deliver universal interoperability, transparent communication, automated management, self-integration, self-adaptation, and security to all the interconnected services, components, and devices in the ecosystem. Overall, the proposed model seeks to deliver a co...

Use of terrestrial toxicity tests for Superfund site assessments  

SciTech Connect

Most risk assessment efforts that evaluate risk from hazardous waste sites have focused on potential human health effects. Concern for potential ecological risk has become a prominent factor in these assessments. The potential impact on all components of ecological systems at risk (including the human component) has prompted the regulatory community to take a more comprehensive approach to risk assessments, incorporating terrestrial toxicity testing. Terrestrial toxicity testing ultimately strengthens the overall risk assessment since responses of feral animals in their natural habitats have important implications in human health. Many biological indicators of stress in animals can be extrapolated to human health as well. Reliance on terrestrial toxicity testing for hazardous waste sites provides both a priori toxicity tests of single chemicals (generally conducted in a laboratory setting), or site-specific testing of extant contamination. Using bioassays of toxicity of environmental samples or in situ testing. Appropriate toxicity tests with representative chemicals and chemical bioavailability, on appropriate species will greatly enhance the information gained and widen mitigation options. Risk managers will be better able to integrate and evaluate toxicity information for the entire system at risk, including the human component. The authors present several matrices that relate chemical action, anticipated toxic effects, and possible terrestrial effects that can be used to provide more comprehensive and ecologically realistic risk assessments at hazardous waste sites.

Within this context, an accurate individuation of SPs, namely the biological component of a given ecosystem that supports human activities is fundamental. \\{SPs\\} are the agents responsible for making the ES-based approach operational. The application of these concepts to the marine environment should be based on an model different to the terrestrial one. In the latter, the basic model envisages a matrix of a human-altered landscape with fragments of original biodiversity; conversely, in the marine environment the model provides fragments where human activities are carried out and the matrix is represented by the original biodiversity. We have identified three main classes of ES provision: in natural, disturbed and human-controlled environments. Economic valuation of marine \\{ESs\\} is an essential condition for making conservation strategies financially sustainable, as it may stimulate the perceived need for investing in protection and exploitation of marine resources.

Global Emissions of Terpenoid VOCs from Terrestrial Vegetation in the Last Millennium  

SciTech Connect

We investigated the millennial variability of global BVOC emissions by using two independent numerical models: The Model of Emissions of Gases and Aerosols from Nature (MEGAN), for isoprene, monoterpene and sesquiterpene and Lund-Potsdam-Jena General Ecosystem Simulator (LPJ8 GUESS), for isoprene and monoterpenes. We found the millennial trends of global isoprene emissions to be mostly affected by land cover and atmospheric carbon dioxide changes, whereas monoterpene and sesquiterpene emission were dominated by temperature change. Isoprene emissions declined substantially in regions with large and rapid land cover change. In addition, isoprene emission sensitivity to drought proved to have signicant short term global effects. By the end of the past millennium MEGAN isoprene emissions were 634 TgC yr-1 (13% and 19% less than during during 1750-1850 and 1000- 15 1200, respectively) and LPJ-GUESS emissions were 323 TgC yr-1 (15% and 20% less than during 1750-1850 and 1000-1200, respectively). Monoterpene emissions were 89 TgC yr-1 (10% and 6% higher than during 1750-1850 and 1000-1200, respectively) in MEGAN, and 24 TgC yr-1 (2% higher and 5% 19 20 less than during 1750-1850 and 1000-1200, respectively) in LPJ-GUESS.

Estimation of Net Ecosystem Carbon Exchange for the Conterminous UnitedStates by Combining MODIS and AmeriFlux Data  

SciTech Connect

Eddy covariance flux towers provide continuous measurements of net ecosystem carbon exchange (NEE) for a wide range of climate and biome types. However, these measurements only represent the carbon fluxes at the scale of the tower footprint. To quantify the net exchange of carbon dioxide between the terrestrial biosphere and the atmosphere for regions or continents, flux tower measurements need to be extrapolated to these large areas. Here we used remotely-sensed data from the Moderate Resolution Imaging Spectrometer (MODIS) instrument on board NASA's Terra satellite to scale up AmeriFlux NEE measurements to the continental scale. We first combined MODIS and AmeriFlux data for representative U.S. ecosystems to develop a predictive NEE model using a regression tree approach. The predictive model was trained and validated using NEE data over the periods 2000-2004 and 2005-2006, respectively. We found that the model predicted NEE reasonably well at the site level. We then applied the model to the continental scale and estimated NEE for each 1 km x 1 km cell across the conterminous U.S. for each 8-day period in 2005 using spatially-explicit MODIS data. The model generally captured the expected spatial and seasonal patterns of NEE. Our study demonstrated that our empirical approach is effective for scaling up eddy flux NEE measurements to the continental scale and producing wall-to-wall NEE estimates across multiple biomes. Our estimates may provide an independent dataset from simulations with biogeochemical models and inverse modeling approaches for examining the spatiotemporal patterns of NEE and constraining terrestrial carbon budgets for large areas.

The biophysical link between climate, water, and vegetation in bioenergy agro-ecosystems  

Science Journals Connector (OSTI)

Abstract Land use change for bioenergy feedstocks is likely to intensify as energy demand rises simultaneously with increased pressure to minimize greenhouse gas emissions. Initial assessments of the impact of adopting bioenergy crops as a significant energy source have largely focused on the potential for bioenergy agroecosystems to provide global-scale climate regulating ecosystem services via biogeochemical processes. Such as those processes associated with carbon uptake, conversion, and storage that have the potential to reduce global greenhouse gas emissions (GHG). However, the expansion of bioenergy crops can also lead to direct biophysical impacts on climate through water regulating services. Perturbations of processes influencing terrestrial energy fluxes can result in impacts on climate and water across a spectrum of spatial and temporal scales. Here, we review the current state of knowledge about biophysical feedbacks between vegetation, water, and climate that would be affected by bioenergy-related land use change. The physical mechanisms involved in biophysical feedbacks are detailed, and interactions at leaf, field, regional, and global spatial scales are described. Locally, impacts on climate of biophysical changes associated with land use change for bioenergy crops can meet or exceed the biogeochemical changes in climate associated with rising GHG's, but these impacts have received far less attention. Realization of the importance of ecosystems in providing services that extend beyond biogeochemical GHG regulation and harvestable yields has led to significant debate regarding the viability of various feedstocks in many locations. The lack of data, and in some cases gaps in knowledge associated with biophysical and biochemical influences on landatmosphere interactions, can lead to premature policy decisions.

Imaging the Earth's Interior: the Angular Distribution of Terrestrial Neutrinos  

E-Print Network (OSTI)

Decays of radionuclides throughout the Earth's interior produce geothermal heat, but also are a source of antineutrinos. The (angle-integrated) geoneutrino flux places an integral constraint on the terrestrial radionuclide distribution. In this paper, we calculate the angular distribution of geoneutrinos, which opens a window on the differential radionuclide distribution. We develop the general formalism for the neutrino angular distribution, and we present the inverse transformation which recovers the terrestrial radioisotope distribution given a measurement of the neutrino angular distribution. Thus, geoneutrinos not only allow a means to image the Earth's interior, but offering a direct measure of the radioactive Earth, both (1) revealing the Earth's inner structure as probed by radionuclides, and (2) allowing for a complete determination of the radioactive heat generation as a function of radius. We present the geoneutrino angular distribution for the favored Earth model which has been used to calculate geoneutrino flux. In this model the neutrino generation is dominated by decays in the Earth's mantle and crust; this leads to a very ``peripheral'' angular distribution, in which 2/3 of the neutrinos come from angles > 60 degrees away from the downward vertical. We note the possibility of that the Earth's core contains potassium; different geophysical predictions lead to strongly varying, and hence distinguishable, central intensities (< 30 degrees from the downward vertical). Other uncertainties in the models, and prospects for observation of the geoneutrino angular distribution, are briefly discussed. We conclude by urging the development and construction of antineutrino experiments with angular sensitivity. (Abstract abridged.)

Integrating Empirical-Modeling Approaches to Improve Understanding of Terrestrial Ecology Processes  

SciTech Connect

Recent decades have seen tremendous increases in the quantity of empirical ecological data collected by individual investigators, as well as through research networks such as FLUXNET (Baldocchi et al., 2001). At the same time, advances in computer technology have facilitated the development and implementation of large and complex land surface and ecological process models. Separately, each of these information streams provides useful, but imperfect information about ecosystems. To develop the best scientific understanding of ecological processes, and most accurately predict how ecosystems may cope with global change, integration of empirical and modeling approaches is necessary. However, true integration - in which models inform empirical research, which in turn informs models (Fig. 1) - is not yet common in ecological research (Luo et al., 2011). The goal of this workshop, sponsored by the Department of Energy, Office of Science, Biological and Environmental Research (BER) program, was to bring together members of the empirical and modeling communities to exchange ideas and discuss scientific practices for increasing empirical - model integration, and to explore infrastructure and/or virtual network needs for institutionalizing empirical - model integration (Yiqi Luo, University of Oklahoma, Norman, OK, USA). The workshop included presentations and small group discussions that covered topics ranging from model-assisted experimental design to data driven modeling (e.g. benchmarking and data assimilation) to infrastructure needs for empirical - model integration. Ultimately, three central questions emerged. How can models be used to inform experiments and observations? How can experimental and observational results be used to inform models? What are effective strategies to promote empirical - model integration?

Assessment of ecosystem biodiversity by acoustic diversity indices  

Science Journals Connector (OSTI)

Assessment of ecosystem biodiversity by measurement of acoustic diversity was explored [B. L. Krause Explorers J. Winter 156160 (1993)]. Specific acoustic indices (e.g. based on frequency spectrum) were developed and correlated with standard diversity indices (e.g. standard species abundance indices). Necessary technological infrastructures and analytic processes to measure acoustic dynamics of ecological biodiversity were explored. An automated web?based infrastructure capable of capturing processing and relaying real?time field measurements from multiple ecosystems to desktop and home computers was developed tested and implemented. Key infrastructure components were remote field instrumentation remote computer processing wireless digital relay instrumentation Internet server and automation relational database and website software. A dynamic digital library of ecological acoustic samples correlated ecosystem attributes and acoustic analysis methodologies was established. Library resources including digital sound files captured from ecosystems were made available to researchers and the public over the Internet [N. Metzger and M. Blumenthal Realizing Info. Future NAP 113119 (1994)]. Indices of acoustic ecosystem diversity were refined through application on existing digital ecosystem sound recordings and digital sounds captured from multiple ecosystems. The performance of these indices was compared to standard biodiversity indices applied to the same ecosystems.

Tourism destinations as digital business ecosystems  

E-Print Network (OSTI)

Tourism has been experiencing very relevant changes since when Information and Communication Technologies (ICTs), in all their forms, have started to pervade the industry and the market. In the last decade, a new concept gained the attention of both researchers and practitioners, that of Digital Business Ecosystem (DBE). It can be considered as a technological infrastructure aimed at creating a digital environment to support and enhance networking between enterprises and stakeholders operating within a sector. Aim of this paper is to assess the extent to which the technological connection has affected the structural configuration of the tourism system and, specifically, of tourism destinations. The present study argues that two components can be considered when assessing the relationships among stakeholders within a tourism destination: a real and a virtual one. Further it shows how these two components are structurally strongly coupled and co-evolve forming a single system.

Assessing the influence of the solar orbit on terrestrial biodiversity  

E-Print Network (OSTI)

The terrestrial fossil record shows a significant variation in the extinction and origination rates of species during the past half billion years. Numerous studies have claimed an association between this variation and the motion of the Sun around the Galaxy, invoking the modulation of cosmic rays, gamma rays and comet impact frequency as a cause of this biodiversity variation. However, some of these studies exhibit methodological problems, or were based on coarse assumptions (such as a strict periodicity of the solar orbit). Here we investigate this link in more detail, using a model of the Galaxy to reconstruct the solar orbit and thus a predictive model of the temporal variation of the extinction rate due to astronomical mechanisms. We compare these predictions as well as those of various reference models with paleontological data. Our approach involves Bayesian model comparison, which takes into account the uncertainties in the paleontological data as well as the distribution of solar orbits consistent wi...

Fermi GBM Observations of Terrestrial Gamma-ray Flashes  

SciTech Connect

Terrestrial Gamma-ray Flashes are short pulses of energetic radiation associated with thunderstorms and lightning. While the Gamma-ray Burst Monitor (GBM) on Fermi was designed to observe gamma-ray bursts, its large BGO detectors are excellent for observing TGFs. Using GBM, TGF pulses are seen to either be symmetrical or have faster rise time than fall times. Some TGFs are resolved into double, partially overlapping pulses. Using ground-based radio observations of lightning from the World Wide Lightning Location Network (WWLLN), TGFs and their associated lightning are found to be simultaneous to {approx_equal}40 {mu} s. The lightning locations are typically within 300 km of the sub-spacecraft point.

Applied Ecosystem Analysis - Background : EDT the Ecosystem Diagnosis and Treatment Method.  

SciTech Connect

This volume consists of eight separate reports. We present them as background to the Ecosystem Diagnosis and Treatment (EDT) methodology. They are a selection from publications, white papers, and presentations prepared over the past two years. Some of the papers are previously published, others are currently being prepared for publication. In the early to mid 1980`s the concern for failure of both natural and hatchery production of Columbia river salmon populations was widespread. The concept of supplementation was proposed as an alternative solution that would integrate artificial propagation with natural production. In response to the growing expectations placed upon the supplementation tool, a project called Regional Assessment of Supplementation Project (RASP) was initiated in 1990. The charge of RASP was to define supplementation and to develop guidelines for when, where and how it would be the appropriate solution to salmon enhancement in the Columbia basin. The RASP developed a definition of supplementation and a set of guidelines for planning salmon enhancement efforts which required consideration of all factors affecting salmon populations, including environmental, genetic, and ecological variables. The results of RASP led to a conclusion that salmon issues needed to be addressed in a manner that was consistent with an ecosystem approach. If the limitations and potentials of supplementation or any other management tool were to be fully understood it would have to be within the context of a broadly integrated approach - thus the Ecosystem Diagnosis and Treatment (EDT) method was born.

Organisms as cooperative ecosystem engineers in intertidal flats  

Science Journals Connector (OSTI)

Abstract The importance of facilitative interactions and organismal ecosystem engineering for establishing the structure of communities is increasingly being recognised for many different ecosystems. For example, soft-bottom tidal flats host a wide range of ecosystem engineers, probably because the harsh physico-chemical environmental conditions render these species of particular importance for community structure and function. These environments are therefore interesting when focusing on how ecosystem engineers interact and the consequences of these interactions on community dynamics. In this review, we initially detail the influence on benthic systems of two kinds of ecosystem engineers that are particularly common in tidal flats. Firstly, we examine species providing biogenic structures, which are often the only source of habitat complexity in these environments. Secondly, we focus on species whose activities alter sediment stability, which is a crucial feature structuring the dynamics of communities in tidal flats. The impacts of these engineers on both environment and communities were assessed but in addition the interaction between ecosystem engineers was examined. Habitat cascades occur when one engineer favours the development of another, which in turn creates or modifies and improves habitat for other species. Non-hierarchical interactions have often been shown to display non-additive effects, so that the effects of the association cannot be predicted from the effects of individual organisms. Here we propose the term of cooperative ecosystem engineering when two species interact in a way which enhances habitat suitability as a result of a combined engineering effect. Finally, we conclude by describing the potential threats for ecosystem engineers in intertidal areas, potential effects on their interactions and their influence on communities and ecosystem function.

Such models typically require PAR data in quantum units (photosynthetic photon flux density) however PAR is often reported in energy units (irradiance). Reliable conversion of diffuse PAR data from energy to quantum units requires knowledge of how the quanta-to-energy ratio for diffuse PAR varies across a broad range of sky conditions that includes variations in cloudiness.

Neutron Science Neutron Science Neutron Scattering Science Neutrons are one of the fundamental particles that make up matter and have properties that make them ideal for certain types of research. In the universe, neutrons are abundant, making up more than half of all visible matter. Neutron scattering provides information about the positions, motions, and magnetic properties of solids. When a beam of neutrons is aimed at a sample, many neutrons will pass through the material. But some will interact directly with atomic nuclei and "bounce" away at an angle, like colliding balls in a game of pool. This behavior is called neutron diffraction, or neutron scattering. Using detectors, scientists can count scattered neutrons, measure their energies and the angles at which they scatter, and map their final position

THE COMPOSITIONAL DIVERSITY OF EXTRASOLAR TERRESTRIAL PLANETS. I. IN SITU SIMULATIONS  

SciTech Connect

Extrasolar planet host stars have been found to be enriched in key planet-building elements. These enrichments have the potential to drastically alter the composition of material available for terrestrial planet formation. Here, we report on the combination of dynamical models of late-stage terrestrial planet formation within known extrasolar planetary systems with chemical equilibrium models of the composition of solid material within the disk. This allows us to determine the bulk elemental composition of simulated extrasolar terrestrial planets. A wide variety of resulting planetary compositions are found, ranging from those that are essentially 'Earth like', containing metallic Fe and Mg silicates, to those that are dominated by graphite and SiC. This shows that a diverse range of terrestrial planets may exist within extrasolar planetary systems.

Current issues in terrestrial solar radiation instrumentation for energy, climate, and space applications  

Science Journals Connector (OSTI)

Uncertainty in terrestrial solar radiation measurements of a few watts per square metre (1 W/m2 to 2 W/m2) is needed to validate estimates of the Earth's radiation balance derived from satellite data. The characterization of solar energy resources for renewable energy technologies requires similar accuracy for economical technology deployment. Solar radiation measurement research at the National Renewable Energy Laboratory addresses calibrations, operational characteristics, and corrections for terrestrial solar radiation measurements. The characterization of field instrument geometric and thermal responses contributing to radiometric errors is described, together with correction schemes reducing the uncertainty of broadband irradiance measurements from tens of watts per square metre to a few (2 W/m2 to 5 W/m2). Such improvements in accuracy reduce the time and labour required for detecting and quantifying trends in terrestrial solar radiation and possible changes in the Earth's radiation budget.

Seasonal and inter-annual variability in 13C composition of ecosystem carbon fluxes in the U.S. Southern Great Plains  

SciTech Connect

The {delta}{sup 13}C signature of terrestrial carbon fluxes ({delta}{sub bio}) provides an important constraint for inverse models of CO{sub 2} sources and sinks, insight into vegetation physiology, C{sub 3} and C{sub 4} vegetation productivity, and ecosystem carbon residence times. From 2002-2009, we measured atmospheric CO{sub 2} concentration and {delta}{sup 13}C-CO{sub 2} at four heights (2 to 60 m) in the U.S. Southern Great Plains (SGP) and computed {delta}{sub bio} weekly. This region has a fine-scale mix of crops (primarily C{sub 3} winter wheat) and C{sub 4} pasture grasses. {delta}{sub bio} had a large and consistent seasonal cycle of 6-8{per_thousand}. Ensemble monthly mean {delta}{sub bio} ranged from -25.8 {+-} 0.4{per_thousand} ({+-}SE) in March to -20.1 {+-} 0.4{per_thousand} in July. Thus, C{sub 3} vegetation contributed about 80% of ecosystem fluxes in winter-spring and 50% in summer-fall. In contrast, prairie-soil {delta}{sub 13}C values were about -15{per_thousand}, indicating that historically the region was dominated by C{sub 4} vegetation and had more positive {delta}{sub bio} values. Based on a land-surface model, isofluxes ({delta}{sub bio} x NEE) in this region have large seasonal amplitude because {delta}{sub bio} and net ecosystem exchange (NEE) covary. Interannual variability in isoflux was driven by variability in NEE. The large seasonal amplitude in {delta}{sub bio} and isoflux imply that carbon inverse analyses require accurate estimates of land cover and temporally resolved {sup 13}CO{sub 2} and CO{sub 2} fluxes.

An ORNL team is using a novel combination of neutron reflectometry experiments and supercomputer simulations to provide a detailed view of the interactions between organic matter and minerals in soil. The research suggests that relationships among these compounds are governed by simpler principles than previously thought. "It changes the whole way we think about how carbon, nutrients and contaminants interact with soils, which therefore affects fertility, water quality, and the terrestrial carbon cycle," said ORNL's Loukas Petridis. "We don't understand these topics very well because until now we haven't had the techniques capable
