Distribution of benthic chlorophyll in San Francisco Bay, California, February 1980 - February 1981
Janet Kay Thompson, Frederic H. Nichols, Sally M. Wienke
1981, Open-File Report 81-1134
Benthic microalgae biomass (chlorophyll a) data from San Francisco Bay are presented for the period February 1980 through February 1981. Benthic chlorophyll a was sampled throughout the bay (maximum of 54 stations) at bimonthly intervals and at monthly intervals at up to 14 stations in the southern bay. Ancillary data...
Chemical analysis of 45 Maryland coal samples
Charles L. Oman, Linda J. Bragg, H.M. Nock, L.J. Schwarz, J.L. Harris, N. H. Rega, S.S. Crowley
1981, Open-File Report 81-1099
This report is part of a continuing program by the U.S. Geological Survey, State Geological Surveys, and the Coal Analysis Section of theU.S. Department of Energy to provide chemical data on the composition of important coal beds of the United States of America. Such data are useful in determining the...
Statistical analyses of data on stream sediments, panned heavy-mineral concentrates, rocks, and waters of the Pusch Ridge Wilderness Area, Arizona
Margaret Hinkle, J.E. Kilburn, R. G. Eppinger, W. S. Speckman
1981, Open-File Report 81-436
The U.S. Geological Survey and the U.S. Bureau of Mines have conducted a mineral-resource assessment of the Pusch Ridge Wilderness Area, in Pima County near Tucson Arizona. The study consisted of coordinated geological, geochemical, and mineral resource studies with the objective of evaluating the potential for mineral deposits in the...
Spectroscopic geochemical study of vanadiferous marine sediments of the Gibellini claims, southern Fish Creek Range, Eureka County, Nevada
J.K. Böhlke, A. S. Radtke, Chris Heropoulos, P. J. Lamothe
1981, Open-File Report 81-32
Samples of cuttings from three drill holes in the Gibellini claims were analyzed by emission spectroscopic techniques for a large suite of major and trace elements. Unoxidized siliceous "black shale" from drill hole NGA 7 is strongly enriched in Cd, Mo, Sb, Se, V, and Zn, and also contains relatively...
Description of seafloor sediment and preliminary geo-environmental report, Shelikof Strait, Alaska
Monty A. Hampton, K.H. Johnson, M.E. Torresan, W.J. Winters
1981, Open-File Report 81-1133
Shelikof Strait, situated between the Kodiak Island group and the Alaska Peninsula (Fig. 1), is included in OCS oil and gas lease area 60. Environmental geologic studies are being conducted by the U.S. Geological Survey prior to the scheduled September 1981 sale date. Seismic-reflection records, collected with 40- to 95-cm3...
Sample catalog for core CL-80-1, Clear Lake, Lake County, California
Michael J. Rymer, John D. Sims, Charles W. Hedel, W.D. Bridge, R.S. Makdisi, G.A. Mannshardt
1981, Open-File Report 81-245
A 177-m-long core designated CL-80-1 was taken from Clear Lake, Calif., during July and August, 1980, at latitude 39.08°N, longitude 122.84°W (fig. 1). The core was removed from Clear Lake for interdisciplinary studies and regional correlation of paleoclimates, paleoecologies, paleolimnology, Quaternary dating techniques, and frequency of volcanic eruptions. This catalog...

R.L. Bassett, E.P. Weeks, M.L. Ceazan, S.G. Perkins, D. C. Signor, D.L. Redinger, Ronald L. Malcolm, G. R. Aiken, E.M. Thurman, P.A. Avery, W.W. Wood, G.M. Thompson, G.K. Stiles
1981, Open-File Report 81-149
A series of artificial recharge experiments was conducted by the U.S. Geological Survey at an experimental site located in Stanton, Texas. Five tests were performed from March 1977 through December 1978 to: (1) Evaluate the hydraulic properties of the aquifer; (2) test sampling and monitoring equipment; (3) compare tracers for...
