The Chesapeake Bay is the Nation's largest estuary and historically supported one of the most productive fisheries in the world. In addition to supporting aquatic communities and wildlife, the bay's watershed serves the economic and recreational needs of 15 million people. The fertile soils of the watershed support significant agricultural...

Methods of analysis by the U.S. Geological Survey National Water Quality Laboratory-Determination of organophosphate pesticides in filtered water by gas chromatography with flame photometric detection
Virendra K. Jha, Duane S. Wydoski
2002, Water-Resources Investigations Report 2002-4071
A method for the isolation of 20 parent organophosphate pesticides and 5 pesticide degradates from filtered natural-water samples is described. Seven of these compounds are reported permanently with an estimated concentration because of performance issues. Water samples are filtered to remove suspended particulate matter, and then 1 liter of filtrate...

2002, Hydrologic Atlas 747
The Black Hills area is an important resource center that provides an economic base for western South Dakota through tourism, agriculture, the timber industry, and mineral resources. In addition, water originating from the area is used for municipal, industrial, agricultural, and recreational purposes throughout much of western South Dakota. The...
Influence of natural organic matter on the adsorption of metal ion onto clay particles
D. Schmitt, Howard E. Taylor, G. R. Aiken, D.A. Roth, F.H. Frimmel
2002, Environmental Science & Technology (36) 2932-2938
The influence of natural organic matter (NOM) on the adsorption of Al, Fe, Zn, and Pb onto clay minerals was investigated. Adsorption experiments were carried out at pH = 5 and pH = 7 in the presence and absence of NOM. In general, the presence of NOM decreased the adsorption...
Effects of flow on the fish communities of a regulated California river: Implications for managing native fishes
Larry R. Brown, Tim Ford
2002, River Research and Applications (18) 331-342
We assessed the importance of flow regime to the success of native and non‐native fish species by analysing winter/spring seining data collected from 1987 to 1997 on the resident fish communities of the lower Tuolumne River, California. The data were analysed using regression models to predict the percentage of non‐native...
An ENSO predictor of dust emission in the southwestern United States
Gregory S Okin, Marith C. Reheis
2002, Geophysical Research Letters (29) 46-1-46-3
Here we show that there is a significant relationship between Nino 3.4 ENSO anomaly (Dec–Jan average) and precipitation in the southwestern United States. This contributes to increased frequency of dust events in the years following strong La Niña and El Niño years. High probabilities (60%–100%) exist for...
A Geochemical Trophic Cascade in Yellowstone's Geothermal Environments
R.A. Garrott, L. E. Eberhardt, James K. Otton, P.J. White, Maurice A. Chaffee
2002, Ecosystems (5) 659-666
We contrast the geochemistry of the Madison drainage, which has high concentrations of geothermal features, with the Lamar drainage of Yellowstone National Park, USA, and trace the consequences of geochemical differences through abiotic and biotic linkages in the ecosystem. Waters in the geothermal-dominated drainage contained anomalously high levels of fluoride...
New insights on timing of oil and gas generation in the central Gulf Coast interior zone based on hydrous-pyrolysis kinetic parameters
Michael D. Lewan, Shirley P. Dutton, Stephen C. Ruppel, Tucker F. Hentz
2002, Conference Paper
Timing of oil and gas generation from Turonian and Smackover source rocks in the central Gulf CoastInterior Zone was determined in one-dimensional burial-history curves (BHCs) using hydrous-pyrolysis kinetic parameters. The results predict that basal Smackover source-rock...

Swimming performance of upstream migrant fishes: New methods, new perspectives
Theodore R. Castro-Santos
2002, Thesis
The ability to traverse barriers of high water velocity limits the distributions of many diadromous and other migratory fish species, and is central to effective fishway design. This dissertation provides a detailed analysis of volitional sprinting behavior of six migratory fish species (American shad Alosa sapidissima, alewife A. pseudoharengus, blueback...

Distribution of high-temperature (>150 °C) geothermal resources in California
John H. Sass, Susan S. Priest
2002, Open-File Report 2002-132
California contains, by far, the greatest geothermal generating capacity in the United States, and with the possible exception of Alaska, the greatest potential for the development of additional resources. California has nearly 2/3 of the US geothermal electrical installed capacity of over 3,000 MW. Depending on assumptions regarding reservoir characteristics...

The area offshore of New York City has been used for the disposal of dredged material for over a century. The area has also been used for the disposal of other materials such as acid waste, industrial waste, municipal sewage sludge, cellar dirt, and wood. Between 1976 and 1995, the...
Analysis of nitrate (NO3-N) concentration trends in 25 ground-water-quality management areas, Idaho, 1961-2001
D. J. Parliman
2002, Water-Resources Investigations Report 2002-4056
In Idaho, drinking-water supplies are pumped from relatively shallow ground-water zones where water quality has great potential for degradation by land- and water-use activities. One indicator of water quality, and one of the most widespread contaminants in Idaho ground water related to land and water uses, is dissolved nitrate. In December 2000, the U.S. Geological Survey, in cooperation...
Techniques for estimating selected streamflow characteristics of rural, unregulated streams in Ohio
G. F. Koltun, Matthew T. Whitehead
2002, Water-Resources Investigations Report 2002-4068
This report provides equations for estimating mean annual streamflow, mean monthly streamflows, harmonic mean streamflow, and streamflow quartiles (the 25th-, 50th-, and 75th-percentile streamflows) as a function of selected basin characteristics for rural, unregulated streams in Ohio. The equations were developed from streamflow statistics and basin-characteristics data for as many...

GPR data processing computer software for the PC
Jeffrey E. Lucius, Michael H. Powers
2002, Open-File Report 2002-166
The computer software described in this report is designed for processing ground penetrating radar (GPR) data on Intel-compatible personal computers running the MS-DOS operating system or MS Windows 3.x/95/98/ME/2000. The earliest versions of these programs were written starting in 1990. At that time, commercially available GPR software did not meet...
