Plankton studies in San Francisco Bay; II, Phytoplankton abundance and species composition, July 1977-December 1979
Raymond L. J. Wong, James E. Cloern
1981, Open-File Report 81-214
Data are presented on the phytoplankton species composition and abundance in San Francisco Bay from July 1977 through December 1979. Phytoplankton identification and enumerations were made at selected stations. Sample collections were made at selected stations in the main channel of the Bay from Rio Vista on the Sacramento River...

Water Resources Division, U.S. Geological Survey
1981, Water Data Report WA-81-1
Water-resources data for the 1981 water year for Washington consist of records of stage, discharge, and water quality of streams; stage, contents, and water quality of lakes and reservoirs; and water levels and water quality of ground-water. This report, in two volumes, contains records for water discharge at 229 gaging...
High-resolution seismic-reflection profiles from the Duxbury, Massachusetts, area
Kenneth F. Parolski
1981, Open-File Report 81-358
In August 1980, The U.S. Geological Survey conducted a seismic study (fig. 1) of the harbor and nearshore waters of Duxbury, Massachusetts, aboard the 38' research vessel R/V NEECHO. In all, 18.5 kilometers of high-resolution seismic profiles and sidescan-sonar data were obtained.The systems used included an 80-J minisparker and an...
Revised techniques for estimating magnitude and frequency of floods in Montana
Charles Parrett, R. J. Omang
1981, Open-File Report 81-917
Relations for estimating the flood magnitudes for ungaged sites in Montana have been updated. The State was divided into eight regions and separate multiple-regression equations for each region were developed that relate logarithms of annual flood magnitude to logarithms of basin characteristics for exceedance probabilities of 50, 20, 10, 4,...
Evaluation of radar imagery for geological and cartographic applications
Gerald K. Moore, Cynthia A. Sheehan
1981, Open-File Report 81-1358
The House/Senate conference report on H.R. 4930 (96th Congress), the Department of the Interior and Related Agencies Appropriations bill, 1980, stated that the U.S. Geological Survey should "begin the use of side-looking airborne radar imagery for topographic and geological mapping, and geological resource surveys in promising areas, particularly Alaska." In...
Potentially favorable areas for large-yield wells in the Red River Formation and Madison Limestone in parts of Montana, North Dakota, South Dakota, Wyoming, and Nebraska
L.M. MacCary, E. M. Cushing, David L. Brown
1981, Open-File Report 81-220
The need for large quantities of energy has created interest in the Fort Union coal region of the Northern Great Plains. Extensive development of this coal, which may include onsite steam-power generation, gasification, liquefaction, and slurry-pipeline transport of the coal from this region, would place a heavy demand on the...
Water resources data, Louisiana, water year 1981, volume 2. Southern Louisiana
Water Resources Division, U.S. Geological Survey
1981, Water Data Report LA-81-2
Water resources data for the 1981 water year for Louisiana consist of records of stage, discharge, and water quality of streams; stage, contents, and water quality of lakes and reservoirs; and water levels and water quality of ground water. This report, in three volumes, contains records for water discharge at...
Petrogenetic modeling of a potential uranium source rock, Granite Mountains, Wyoming
J. S. Stuckless, A.T. Miesch
1981, Professional Paper 1225
Previous studies of the granite of Lankin Dome have led to the conclusion that this granite was a source for the sandstone-type uranium deposits in the basins that surround the Granite Mountains, Wyo. Q-mode factor analysis of 29 samples of this granite shows that five bulk compositions are required to...
Biogeochemical variability of plants at native and altered sites, San Juan Basin, New Mexico
L. P. Gough, R. C. Severson
1981, Professional Paper 1134-D
The San Juan Basin is becoming a major energy resource region. The anticipated increase in strip mining for coal can be expected to alter the geochemical and biogeochemical environment. because such activities destroy the native vegetation communities, rearrange the rock strata, and disrupt natural soil development. This study investigated the...
Selected drill-stem-test data from the Northern Great Plains area of Montana
Gary W. Levings
1981, Open-File Report 81-326
Selected drill-stem-test data were collected for use in the hydrologic analysis of aquifers in the northern Great Plains area of Montana. To supplement existing data defining the potentiometric surface of various aquifers, shut-in pressures recorded during drill-stem tests of oil and gas test wells were used to calculate the altitude...
Hydrologic data for the Cache Creek-Bear Thrust environmental impact statement near Jackson, Wyoming
G.S. Craig Jr., B. H. Ringen, E.R. Cox
1981, Open-File Report 81-410
Information on the quantity and quality of surface and ground water in an area of concern for the Cache Creek-Bear Thrust Environmental Impact Statement in northwestern Wyoming is presented without interpretation. The environmental impact statement is being prepared jointly by the U.S. Geological Survey and the U.S. Forest Service and...
Proceedings of the Symposium on Mineral Deposits of the Pacific Northwest: Geological Society of America, Cordilleran Section meeting at Corvallis, Oregon, March 20-21, 1980
Miles L. Silberman, C. W. Field, Anne L. Berry
1981, Open-File Report 81-355
Stratiform and volcanogenic zinc-lead-barium deposits occur within the pelagic Kagvik sequence in the Red Dog Creek and Drenchwater Creek areas in the DeLong Mountains and Howard Pass quadrangles. The sulfide deposits occur together with barite, tuff, sandstone, shale, chert, and keratophyre flows and sills. The three main occurrences of the...
