Seasonal variations in sup 7 Be activity in the sediments of Cape Lookout Bight, North Carolina  

SciTech Connect (OSTI)

Short-term sediment accumulation rates were determined using activity distribution of {sup 7}Be in the surficial sediments of a station (A-1) in Cape Lookout Bight, North Carolina (USA). This semi-enclosed coastal marine basin is characterized by high annual accumulation rates. Protected from high energy conditions by its geomorphology, the relatively quiescent waters of the bight's interior cause it to act as an efficient settling trap for fine-grained sediment. Lack of bioturbation in the surface sediments allowed for variations in depth-integrated activity profiles of {sup 7}Be to be interpreted as short-term accumulation events. Beryllium-7 inventories exhibited seasonal cyclicity with maxima occurring during spring (February through June). The inventory of {sup 7}Be ranged from 5.8 to 32.6 dpm cm{sup {minus}2} and was always well in excess of the atmospherically supported value ({bar x} = 3.8 dpm cm{sup {minus}2}; n = 15). Accumulation rates calculated from {sup 7}Be activity profiles indicate that the delivery of particulate matter to the sediments of Cape Lookout Bight is not constant throughout an annual cycle. The highest monthly accumulation rates appeared to be associated with north/northeastern storm activity. Inputs were generally highest during late winter/early spring when storm frequency is greatest. Short-term accumulation rates derived from this study agree with {sup 210}Pb rates calculated for a ten-year period of accumulation. The annual sediment accumulation rates for each of the two years over which the study was conducted was found to be 4.8 {plus minus} 0.8 g cm{sup {minus}2}y{sup {minus}1} and 3.7 {plus minus} 1.2 g cm{sup {minus}2}y{sup {minus}1}.

Hydroacoustic Evaluation of Juvenile Salmonid Passage and Distribution at Lookout Point Dam, 2010  

SciTech Connect (OSTI)

Pacific Northwest National Laboratory evaluated juvenile salmonid passage and distribution at Lookout Point Dam (LOP) on the Middle Fork Willamette River for the U.S. Army Corps of Engineers, Portland District (USACE), to provide data to support decisions on long-term measures to enhance downstream passage at LOP and others dams in USACE's Willamette Valley Project. This study was conducted in response to the listing of Upper Willamette River Spring Chinook salmon (Oncorhynchus tshawytscha) and Upper Willamette River steelhead (O. mykiss) as threatened under the Endangered Species Act. We conducted a hydroacoustic evaluation of juvenile salmonid passage and distribution at LOP during February 2010 through January 2011. Findings from this 1 year of study should be applied carefully because annual variation can be expected due to variability in adult salmon escapement, egg-to-fry and fry-to-smolt survival rates, reservoir rearing and predation, dam operations, and weather. Fish passage rates for smolt-size fish (> {approx}90 mm and < 300 mm) were highest during December-January and lowest in mid-summer through early fall. Passage peaks were also evident in early spring, early summer, and late fall. During the entire study period, an estimated total of 142,463 fish {+-} 4,444 (95% confidence interval) smolt-size fish passed through turbine penstock intakes. Of this total, 84% passed during December-January. Run timing for small-size fish ({approx}65-90 mm) peaked (702 fish) on December 18. Diel periodicity of smolt-size fish showing crepuscular peaks was evident in fish passage into turbine penstock intakes. Relatively few fish passed into the Regulating Outlets (ROs) when they were open in summer (2 fish/d) and winter (8 fish/d). Overall, when the ROs were open, RO efficiency (RO passage divided by total project passage) was 0.004. In linear regression analyses, daily fish passage (turbines and ROs combined) for smolt-size fish was significantly related to project discharge (P<0.001). This relationship was positive, but there was no relationship between total project passage and forebay elevation (P=0.48) or forebay elevation delta, i.e., day-to-day change in forebay elevation (P=0.16). In multiple regression analyses, a relatively parsimonious model was selected that predicted the observed data well. The multiple regression model indicates a positive trend between expected daily fish passage and each of the three variables in the model-Julian day, log(discharge), and log(abs(forebay delta)); i.e., as any of the environmental variables increase, expected daily fish passage increases. For vertical distribution of fish at the face of the dam, fish were surface-oriented with 62%-80% occurring above 10 m deep. The highest percentage of fish (30%-60%) was found between 5-10-m-deep. During spring and summer, mean target strengths for the analysis periods ranged from -44.2 to -42.1 dB. These values are indicative of yearling-sized juvenile salmon. In contrast, mean target strengths in fall and winter were about -49.0 dB, which are representative of subyearling-sized fish. The high-resolution spatial and temporal data reported herein provide detailed information about vertical, horizontal, diel, daily, and seasonal fish passage rates and distributions at LOP from March 2010 through January 2011. This information will support management decisions on design and development of surface passage and collection devices to help restore Chinook salmon populations in the Middle Fork Willamette River watershed above LOP.

Sediment-water chemical exchange in the coastal zone traced by in situ radon-222 flux measurements  

SciTech Connect (OSTI)

In situ radon-222 flux experiments conducted in benthic chambers in Cape Lookout Bight, a small marine basin on the North Carolina coast, reveal that enhanced chemical transport across the sediment-water interface during summer months is caused by abiogenic bubble tube structures. Transport rates for dissolved radon, methane, and ammonium more than three times greater than those predicted on the basis of molecular diffusion occur when open tubes are maintained by semidiurnal low-tide bubbling.

Biogeochemical cycling in an organic-rich coastal marine basin: 11. The sedimentary cycling of dissolved, free amino acids  

SciTech Connect (OSTI)

In the anoxic sediments of Cape Lookout Bight, NC, concentrations of total dissolved free amino acids (TDFAAs) are highest near the sediment-water interface, and decrease to non-zero, asymptotic concentrations at depths greater than 20 cm. TDFAAs in the overlying waters are <1 {mu}M. Dissolved free amino acid (DFAA) profiles often show a secondary subsurface maximum in the region between the 1 and 5 mM sulfate isopleths. This phenomenon appears to be related to the transition in the sediments of this region from sulfate reduction to methanogenesis. A steady-state diagenetic model which quantifies the processes affecting DFAAs in these sediments yields rates of DFAA production and consumption that agree reasonably well with independent estimates of these quantities in Cape Lookout Bight and other anoxic marine sediments. The combined results of modelling pore water DFAA and sedimentary amino acid profiles indicate that significant exchange of amino acids occurs between the sediments and pore waters. These results demonstrate that the biogeochemistry of dissolved free amino acids in the pore waters of Cape Lookout Bight sediments is dominated by internal transformations (i.e. production from sedimentary amino acids, microbial remineralization, and reincorporation back into the sediments). There is some uncertainty in the magnitude of the flux of DFAAs across the sediment-water interface, although it appears to be of secondary importance when compared to the other sedimentary processes affecting DFAAs.

Biogeochemical cycling in an organic-rich coastal marine basin. 10. The role of amino acids in sedimentary carbon and nitrogen cycling  

SciTech Connect (OSTI)

Hydrolyzable amino acids were measured in cores and surface sediment samples collected over a 14 month period from the rapidly accumulating, anoxic sediments of Cape Lookout Bight, NC. The concentration of total hydrolyzable amino acids (THAAs) shows an exponential decrease with depth, in a manner similar to total organic carbon and total nitrogen. Carbon and nitrogen in THAAs averages 10-15% of the total organic carbon and 30-40% of the total nitrogen in these sediments. In surface sediments the concentration of THAAs do not show strong seasonal variations, with the exception of a small apparent decrease during the winter months. Aspartic acid, glutamic acid, glycine and alanine are the most abundant individual amino acids in Cape Lookout Bight sediments. The distribution of individual amino acids in these sediments is very similar to that observed in the two major sources of organic matter, vascular salt marsh plants and marine plankton. The mole fractions of most amino acids show no depth variation in Cape Lookout Bight sediments. Kinetic modeling of these data indicates that the deposition of amino acids to the surface of these sediments is 5.8 {plus minus} 1.0 mol{center dot}m{sup {minus}2}{center dot}yr{sup {minus}1}. Approximately 46 {plus minus} 16% of this input is remineralized in the upper 40 cm. The recycling of amino acids accounts for 82 {plus minus} 43% of the total nitrogen regeneration and 27 {plus minus} 11% of the regeneration of total organic carbon in these sediments. The mean residence time of metabolizable amino acids is approx. 9 months, a value which is comparable to the mean residence time of both metabolizable organic carbon and nitrogen in these sediments.

Seasonal variations in the stable carbon isotopic signature of biogenic methane in a coastal sediment  

SciTech Connect (OSTI)

Systematic seasonal variations in the stable carbon isotopic signature of methane gas occur in the anoxic sediments of Cape Lookout Bight, a lagoonal basin on North Carolina's Outer Banks. Values for the carbon isotope ratio (delta /sup 13/C) of methane range from -57.3 per mil during summer to -68.5 per mil during winter in gas bubbles with an average methane content of 95%. The variations are hypothesized to result from changes in the pathways of microbial methane production and cycling of key substrates including acetate and hydrogen. The use of stable isotopic signatures to investigate the global methane cycle through mass balance calculations, involving various sediment and soil biogenic sources, appears to require seasonally averaged data from individual sites. 17 references, 2 figures, 2 tables.

Coastwatch Coastwatch Agriculture Community Menu DATA APPS EVENTS DEVELOPER STATISTICS COLLABORATE ABOUT Agriculture You are here Data.gov » Communities » Agriculture » Data Coastwatch Dataset Summary Description NOAA CoastWatch was established in 1987 in response to two significant environmental events. A Harmful Algal Bloom (HAB) event occurred off the coast of North Carolina transporting the toxic Gymnodinium breve cells from Florida via the Gulf Stream into the colder coastal waters near Cape Lookout. Also, a severe mammal die-off occurred, where more than 700 bottlenose dolphins died off the mid-Atlantic coast. Both instances prompted Federal and State officials to explore additional data sources for monitoring the coastal waters, such as near real-time satellite data. CoastWatch has expanded from POES/AVHRR SST data for the East Coast to providing a variety of environmental data (i.e. SST, ocean color, winds, etc.) from several different satellite platforms covering all U.S. coastal waters, including Hawaii and Alaska. Today, sea surface temperature maps support meteorological weather predictions and also support commercial and recreational activities (e.g., fishing). Biologists utilize ocean color radiometry data and derived chlorophyll-a and total suspended matter/turbidity products to identify runoff plumes and blooms and also predict HABs; and sailors and commercial shipping pilots use ocean surface vector winds for safe navigation.

Biogeochemical cycling in an organic-rich coastal marine basin. 9. Sources and accumulation rates of vascular plant-derived organic material  

SciTech Connect (OSTI)

The sources, degradation and burial of vascular plant debris deposited over the past several decades in the lagoonal sediments of Cape Lookout Bight, North Carolina, are quantified using alkaline cupric oxide lignin oxidation product (LOP) analysis. Non-woody angiosperms, accounting for 92 {plus minus} 32% of the recognizable sedimentary vascular plant debris, are calculated to contribute 23 {plus minus} 17% of the total organic carbon buried over the past decade. When combined with a previously established sedimentary organic carbon budget for this site a vascular plant derived carbon burial rate of 26 {plus minus}20 mole C m{sup {minus}2} yr{sup {minus}1} is calculated for this same time interval. The refractory nature and invariant depth distributions of the lignin oxidation products (LOP), when coupled with evidence for constant degradation rates of metabolizable materials, indicate that sediment accumulation at this site has been a steady state process with respect to source and burial of organic carbon since its conversion from an inner-continental shelf to a lagoonal environment during the late 1960's. Thus systematic down-core decreases in labile organic matter result from early diagenetic processes rather than input rate variations.

Biogeochemical cycling in an organic-rich coastal marine basin. 5. Sedimentary nitrogen and phosphorus budgets based upon kinetic models, mass balances, and the stoichiometry of nutrient regeneration  

SciTech Connect (OSTI)

The rapid rates of sediment accumulation (approx.10-20 cm/yr) in the recently formed Cape Lookout Bight, North Carolina, have resulted in the deposition of approximately 157 moles of carbon, 14 moles of nitrogen and 1.3 moles of phosphorus, per square meter annually. The metabolism of the organic matter in these anoxic sediments is dominated by sulfate reduction and fermentation reactions. Sedimentary nitrogen and phosphorus budgets are estimated using 3 related approaches: 1) a kinetic model of solid phase diagenesis; 2) direct measurements of nutrient burial and regeneration; and 3) nutrient recycling rates estimated from annual rates of sulfate reduction and the SO/sub 4/:NH/sub 4/ and SO/sub 4/:PO/sub 4/ stoichiometry of nutrient regeneration. The mass balances derived agree reasonably well and indicate that approximately 30% of the total nitrogen and 15% of the total phosphorus deposited in these sediments are recycled. The mean residence time for recycled nutrients within the sediment is 4 to 6 months for nitrogen and 1.5 to 2 years for phosphorus. Nitrogen regeneration, like carbon, appears to be controlled by the microbially-mediated metabolism of labile organic matter. The greater asymmetry and lower percent turnover in phosphorus cycling is apparently due to changes in its solubility under oxidized and reduced conditions and selective regeneration prior to deposition.

Biogeochemical cycling in an organic-rich coastal marine basin. 8. A sulfur isotopic budget balanced by differential diffusion across the sediment-water interface  

SciTech Connect (OSTI)

The sulfur isotopic composition of the sulfur fluxes occurring in the anoxic marine sediments of Cape Lookout Bight, N.C., U.S.A., was determined, and the result of isotopic mass balance was obtained via the differential diffusion model. Seasonal pore water sulfate delta/sup 34/S measurements yielded a calculated sulfate input of 0.6 per thousand. Sulfate transported into the sediments via diffusion appeared to be enriched in the lighter isotope because its concentration gradient was steeper, due to the increase in the measured isotopic composition of sulfate with depth. Similarly, the back diffusion of dissolved sulfide towards the sediment-water interface appeared enriched in the heavier isotope. The isotopic composition of this flux was calculated from measurements of the delta/sup 34/S of dissolved sulfide and was determined to be 15.9 per thousand. The isotopic composition of buried sulfide was determined to be -5.2 per thousand and the detrital sulfur input was estimated to be -6.2 per thousand. An isotope mass balance equation based upon the fluxes at the sediment-water interface successfully predicted the isotopic composition of the buried sulfur flux within 0.5 per thousand, thus confirming that isotopes diffuse in response to their individual concentration gradients.

Biogeochemical cycling in an organic-rich coastal marine basin. 6. Temporal and spatial variations in sulfate reduction rates  

SciTech Connect (OSTI)

Rates of sulfate reduction were measured over a 3 year period in the anoxic nearshore sediments of Cape Lookout Bight, North Carolina, using both a tube incubation method and a /sup 35/S-sulfate direct injection technique. The methods yielded similar depth-integrated rates over the upper 30 cm ranging from less than 10 mol SO/sub 4//sup =/ x m/sup -2/ x y/sup -1/ in winter to greater than 50 mol SO/sub 4//sup =/ x m/sup -2/ x y/sup -1/ in summer. There were also seasonal changes in the Arrhenius activation energies for the sulfate reduction rates indicating that the assumption that E/sub a/ is constant with temperature is not always valid. The time averaged annual turnover rate for all three years was 20.4 (+/- 11.4) mol SO/sub 4//sup =/ x m/sup -2/ x y/sup -1/. Surface rates ranged seasonally from less than 0.01 to over 3 mM SO/sub 4//sup =/ x d/sup -1/ between winter and summer, respectively. A subsurface rate maximum was observed to develop during the summer months which accounted for 28 percent of the annual depth-integrated sulfate reduction rate. Subsurface rate maxima are the result of changes in the chemistry (substrate type and/or concentration) and the microbiology in the sediments. The possibility of the subsurface maximum being an artifact of the /sup 35/S method is also discussed.

Biogeochemical cycling in an organic-rich coastal marine basin. 7. Sulfur mass balance, oxygen uptake and sulfide retention  

SciTech Connect (OSTI)

Sulfur and oxygen fluxes were quantified in the seasonally varying anoxic marine sedimentary system of Cape Lookout Bight, N.C., U.S.A. Over the three year study period, 1981-1983, the mean annual sulfate reduction rate was determined to be 18.2 +/- 1.6 moles x m/sup -2/ x y/sup -1/. This value, added to the estimate of the detrital sulfur input of 1.2 +/- 4.4 gave a total sulfur input of 19.4 +/- 4.7 moles x m/sup -1/ x y/sup 2/)/sup 1/. The sulfide flux to the sediment-water interface, measured in anaerobic benthic chambers was 4.6 +/- 0.5 moles x m/sup -2/ x y/sup -1/, and represented 37% of the annual oxygen uptake rate of 25.2 +/- 2.8 moles x m/sup -2/ x y/sup -1/. The sulfide burial rate, determined to be 15.5 +/- 3.1 moles x m/sup -2/ x y/sup -1/, was within 5% of the value predicted by summing the fluxes at the sediment-water interface. The C/S weight ratio of sediment below the depth of diagenetic reaction was determined to be 2.75. The sulfide retention rate in these rapidly accumulating sediments (10 cm/yr) was 77 +/- 19%. Comparison of this result with previous studies shows that rapid sediment accumulation and the lack of bioturbation control this unusually high degree of sulfide retention.

SUPPORT OF GULF OF MEXICO HYDRATE RESEARCH CONSORTIUM: ACTIVITIES TO SUPPORT ESTABLISHMENT OF A SEA FLOOR MONITORING STATION PROJECT  

SciTech Connect (OSTI)

A Consortium, designed to assemble leaders in gas hydrates research, has been established at the University of Mississippi's Center for Marine Resources and Environmental Technology, CMRET. The primary objective of the group is to design and emplace a remote monitoring station on the sea floor in the northern Gulf of Mexico by the year 2005, in an area where gas hydrates are known to be present at, or just below, the sea floor. This mission necessitates assembling a station that will monitor physical and chemical parameters of the sea water and sea floor sediments on a more-or-less continuous basis over an extended period of time. Development of the station allows for the possibility of expanding its capabilities to include biological monitoring, as a means of assessing environmental health. Establishment of the Consortium has succeeded in fulfilling the critical need to coordinate activities, avoid redundancies and communicate effectively among researchers in this relatively new research arena. Complementary expertise, both scientific and technical, has been assembled to promote innovative research methods and construct necessary instrumentation. Noteworthy achievements one year into the extended life of this cooperative agreement include: (1) Progress on the vertical line array (VLA) of sensors: (1a) Repair attempts of the VLA cable damaged in the October >1000m water depth deployment failed; a new design has been tested successfully. (1b) The acoustic modem damaged in the October deployment was repaired successfully. (1c) Additional acoustic modems with greater depth rating and the appropriate surface communications units have been purchased. (1d) The VLA computer system is being modified for real time communications to the surface vessel using radio telemetry and fiber optic cable. (1e) Positioning sensors--including compass and tilt sensors--were completed and tested. (1f) One of the VLAs has been redesigned to collect near sea floor geochemical data. (2) Progress on the Sea Floor Probe: (2a) With the Consortium's decision to divorce its activities from those of the Joint Industries Program (JIP), due to the JIP's selection of a site in 1300m of water, the Sea Floor Probe (SFP) system was revived as a means to emplace arrays in the shallow subsurface until arrangements can be made for boreholes at >1000m water depth. (2b) The SFP penetrometer has been designed and construction begun. (2c) The SFP geophysical and pore-fluid probes have been designed. (3) Progress on the Acoustic Systems for Monitoring Gas Hydrates: (3a) Video recordings of bubbles emitted from a seep in Mississippi Canyon have been analyzed for effects of currents and temperature changes. (3b) Several acoustic monitoring system concepts have been evaluated for their appropriateness to MC118, i.e., on the deep sea floor. (3c) A mock-up system was built but was rejected as too impractical for deployment on the sea floor. (4) Progress on the Electromagnetic Bubble Detector and Counter: (4a) Laboratory tests were performed using bubbles of different sizes in waters of different salinities to test the sensitivity of the. Differences were detected satisfactorily. (4b) The system was field tested, first at the dock and then at the shallow water test site at Cape Lookout Bight where methane bubbles from the sea floor, naturally, in 10m water depth. The system successfully detected peaks in bubbling as spike decreases in conductivity. (5) Progress on the Mid-Infrared Sensor for Continuous Methane Monitoring: (5a) Modeling and design of an optics platform complementary to the constructed electronics platform for successful incorporation into ''sphereIR'' continues. AutoCAD design and manual construction of mounting pieces for major optical components have been completed. (5b) Initial design concepts for IR-ATR sensor probe geometries have been established and evaluated. Initial evaluations of a horizontal ATR (HATR) sensing probe with fiber optic guiding light have been performed and validate the design concept as a potentially viable deep sea sensing pr
