Correlations among seasonal water quality, discharge, weather, and coverage by submersed aquatic vegetation in the tidal Potomac River and Potomac Estuary, 1983-96
Virginia Carter, N. B. Rybicki, J.M. Landwehr, J. T. Reel, H. Ruhl
1998, Open-File Report 98-657
The U.S. Geological Survey has been cooperating with other scientists under the auspices of the Interstate Commission on the Potomac River Basin to utilize existing data from the tidal Potomac River and Estuary for investigating linkages among living resources (primary producers, consumers) and abiotic components of the environment. Because the...
Fish, benthic macroinvertebrate, and stream habitat data from the Houston-Galveston Area Council service area, Texas, 1997-98
J. Bruce Moring, John C. Rosendale, Stephen P. Ansley, Dexter W. Brown
1998, Open-File Report 98-658
The U.S. Geological Survey collected fish, benthic macroinvertebrate, and stream habitat data at sampling sites in the Houston-Galveston Area Council service area, a 15-county area with a population of about 4.3 million people. The data were collected for a 1997?98 study in cooperation with the Houston-Galveston Area Council to provide...
Geologic map of central (interior) Alaska
Frederic H. Wilson, James H. Dover, Dwight Bradley, Florence R. Weber, Thomas K. Bundtzen, Peter J. Haeussler
1998, Open-File Report 98-133-A
Introduction: This map and associated digital databases are the result of a compilation and reinterpretation of published and unpublished 1:250,000- and limited 1:125,000- and 1:63,360-scale mapping. The map area covers approximately 416,000 sq km (134,000 sq mi) and encompasses 25 1:250,000-scale quadrangles in central Alaska. The compilation was done...
Contributions to the gold metallogeny of northern Nevada

1998, Open-File Report 98-338-B
Nevada is one of the Earth's premier gold producing regions, accounting for approximately 64 percent of the U.S and nine percent of the world total. The impact of these mines on nearby local economies and on our national balance of payments is profound, and will continue well into the next...
Soil, environmental, and watershed measurements in support of carbon cycling studies in northwestern Mississippi
Thomas G. Huntington, J.W. Harden, S. M. Dabney, D. A. Marion, C. Alonso, J. M. Sharpe, T. L. Fries
1998, Open-File Report 98-501
Measurements including soil respiration, soil moisture, soil temperature, and carbon export in suspended sediments from small watersheds were recorded at several field sites in northwestern Mississippi in support of hillslope process studies associated with the U.S. Geological Survey's Mississippi Basin Carbon Project (MBCP). These measurements were made to provide information...
Summary statistics and graphical comparisons of historical hydrologic and water-quality data, Seco Creek Watershed, South-Central Texas
