Water quality in the upper Tennessee River basin, Tennessee, North Carolina, Virginia, and Georgia 1994-98 Water quality in the upper Tennessee River basin, Tennessee, North Carolina, Virginia, and Georgia 1994-98
This report summarizes major findings about water quality in the upper Tennessee River basin that emerged from an assessment conducted between 1994 and 1998 by the U.S. Geological Survey (USGS) National Water-Quality Assessment (NAWQA) Program. Water quality is discussed in terms of local and regional issues and compared to conditions found in all 36 NAWQA study areas, called study units...

Comparison of an enzyme-linked immunosorbent assay (ELISA) to gas chromatography (GC) - measurement of polychlorinated biphenyls (PCBs) in selected US fish extracts Comparison of an enzyme-linked immunosorbent assay (ELISA) to gas chromatography (GC) - measurement of polychlorinated biphenyls (PCBs) in selected US fish extracts
The analysis of PCBs in fish tissues by immunoassay methods was evaluated using fish collected from a US monitoring program, the National Contaminant Biomonitoring Program of the US Department of Interior, Fish and Wildlife Service. Selected composite whole fish samples, which represented widely varying concentrations and sources of PCBs, were extracted and subjected to congener PCB...

A flow cytometric approach to the study of crustacean cellular immunity A flow cytometric approach to the study of crustacean cellular immunity
Responses of hemocytes from the crayfish Procambarus zonangulus to stimulation by fungal cell walls (Zymosan A) were measured by flow cytometry. Changes in hemocyte physical characteristics were assessed flow cytometrically using forward- and sidescatter light parameters, and viability was measured by two-color fluorescent staining with calcein-AM and ethidium homodimer 1. The main...

A method for measuring vertical accretion, elevation, and compaction of soft, shallow-water sediments A method for measuring vertical accretion, elevation, and compaction of soft, shallow-water sediments
High-resolution measures of vertical accretion, elevation, and compaction of shallow-water sediments are fundamental to understanding the processes that control elevation change and the mechanisms of progradation (e.g., development of mudflats and intertidal wetlands) in coastal systems. Yet, measurements of elevation by traditional survey methods often are of low accuracy because of the

Louisiana coastal ecosystem Louisiana coastal ecosystem
Louisiana's coast and its degradation and restoration are major environmental issues being studied at the National Wetlands Research Center. Coastal ecosystems are vulnerable because of the tremendous amount of human activity that takes place along the coast. Information on ecological processes is essential to guide the development along the coast as well as to protect and restore...

Assessment of sedimentation in Crowders Creek, York County, South Carolina, 1999-2000 Assessment of sedimentation in Crowders Creek, York County, South Carolina, 1999-2000
Sedimentation in Crowders Creek cove in Lake Wylie, located in York County, South Carolina, has restricted boat navigation and made a boat ramp unusable. To provide baseline information, the U.S. Geological Survey, in cooperation with the York County Council, collected bathymetric and bed-sediment data in the cove, and streamflow and suspended-sediment data in a free-flowing reach of...

Interagency field manual for the collection of water-quality data Interagency field manual for the collection of water-quality data
Along the United States-Mexico border region, numerous Federal, State, and local agencies; nongovernmental organizations (NGO); and researchers collect water-quality data for many purposes. The water community uses a number of documented and undocumented procedures, some of which have specific data-quality objectives (DQO) and data-information objectives. This mix of procedures results...
Is Acropora palmata (elkhorn coral) making a comeback in the Virgin Islands? Is Acropora palmata (elkhorn coral) making a comeback in the Virgin Islands?
White band disease (WBD) ravaged Acropora palmata (elkhorn coral) on many coral reefs in the Caribbean in the late 1970’s and 1980’s, including those around St. John and St. Croix, U. S. Virgin Islands—USVI (Gladfelter 1982, Rogers 1985). Quantitative data, photographs, and anecdotal observations indicate WBD killed large stands of elkhorn coral in the USVI from about 1976 until sometime...
