1998, Open-File Report 98-623
This digital geologic map compilation presents new polygon (i.e., geologic map unit contacts), line (i.e., fault, fold axis, dike, and caldera wall), and point (i.e., structural attitude) vector data for the Thirsty Canyon NW 7 1/2' quadrangle in southern Nevada. The map database, which is at 1:24,000-scale resolution, provides geologic...
Mississippi Basin Carbon Project science plan
E.T. Sundquist, R.F. Stallard, N.B. Bliss, H. W. Markewich, J.W. Harden, M.J. Pavich, M.D. Dean Jr.
1998, Open-File Report 98-177
Understanding the carbon cycle is one of the most difficult challenges facing scientists who study the global environment. Lack of understanding of global carbon cycling is perhaps best illustrated by our inability to balance the present-day global CO2 budget. The amount of CO2 produced by burning fossil fuels and by...
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...
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This map and associated digital databases are the result of a compilation and reinterpretation of published and unpublished 1:250,000- and limited 1:125,000- and 1:63,360-scale mapping.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...
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...
