Fast-ice thickness and snow depth in relation to oil entrapment potential, Prudhoe Bay, Alaska
Peter W. Barnes, Erk Reimnitz, Lawrence J. Toimil, Harry R. Hill
1979, Open-File Report 79-539
In winter, the undersurface of the sea ice on shallow arctic shelves acts upon the sea bed directly by contact and indirectly by influencing currents and turbulence. The under-ice surface would serve as a trap for pollutants such as oil and gas released from the sea bed. A knowledge of...
Hydrologic reconnaissance of the Wasatch Plateau-Book Cliffs coal-fields area, Utah
K.M. Waddell, P.K. Contratto, C. T. Sumsion, John R. Butler
1979, Open-File Report 79-988
Data obtained during a hydrologic reconnaissance in 1975-77 in the Wasatch Plateau-Book Cliffs coal area of Utah were correlated with existing long-term data. Maps were prepared showing average precipitation, average streamflow, stream temperature, ground- and surface-water quality, sediment yield, and geology. Recommendations were made for additional study and suggested approaches...
Water and sediment measurements in San Francisco Bay, California
Laurence E. Schemel, Andrea E. Alpine, Brian E. Cole, Lee A. Dedini, Elliott C. Spiker
1979, Open-File Report 78-973
Water samples collected in San Francisco Bay, the Gulf of the Farallones, and the delta of the Sacramento and San Joaquin rivers were analyzed for salinity, temperature, partial pressure of carbon dioxide (pCO2), chlorophyll a, alkalinity, particulate organic carbon (POC), and the stable carbon isotope ratio (δ13C) of the POC...
Sediment transport in the Tanana River in the vicinity of Fairbanks, Alaska, 1977-78
Robert L. Burrows, Bruce Parks, William W. Emmett
1979, Open-File Report 79-1539
Measurements of the sediment load of the Tanana River in the vicinity of Fairbanks, Alaska, show that suspended-sediment transport rate in tons per day, relates to water discharge, in cubic feet per second, as: Suspended-sediment transport rate (tons/day) = 5.717 x 10 to the minus 8th power x water discharge...
Water-resources appraisal of the south-Arkansas lignite area
J. E. Terry, C. T. Bryant, A. H. Ludwig, J.E. Reed
1979, Open-File Report 79-924
The feasibility of developing lignite resources in south-central Arkansas is an important question at the present time (1978). Part of the concern is related to the possible impacts that mining and processing of lignite will have on water resources. Not only will the disturbance caused by excavating affect the quantity...
Hexavalent chromium in the ground and surface waters near Telluride, Colorado; preliminary data report
David B. Grove, Ronald L. Miller, Leonard F. Konikow, P. S. O’Boyle
1979, Open-File Report 79-700
Data showing results of 38 groundwater and 25 surface-water samples analyzed for hexavalent chromium are presented. Most samples were taken within the Telluride, Colo., city limits during October 1978. Twenty-four of the 38 groundwater samples (63%) contained more than 50 micrograms per liter of hexavalent chromium. Excluding the mill tailings...
Examples of deep-water-bottom multiple dereverberation techniques applied to seismic-reflection data from the Atlantic Outer Continental Shelf
Steven D. Peterson, A. H. Balch, W.C. Patterson, D. J. Taylor
1979, Open-File Report 79-1572
Seismic-reflection data recorded in deep water over the Atlantic Outer Continental Shelf are often dominated by multiply-reflected seismic energy. This energy reverberates between the surface of the water and the seafloor (or other strong reflectors), and makes portions of the seismic data completely useless. Several different data-processing techniques can be...
Particulate organic carbon in San Francisco Bay, California, 1971-1977
Laurence E. Schemel, Lee A. Dedini
1979, Open-File Report 79-512
The organic-carbon content of suspended particulate matter is determined by wet oxidation and analysis of the resulting CO2 with an infrared analyzer. Modifications of methods and improved designs of apparatus are presented.Results of particulate organic carbon (POC) analyses from 1971 through 1977 show that concentrations in North San Francisco Bay...
Geology and industrial mineral resources of the Macon-Gordon kaolin district, Georgia
Bennett Frank Buie, J. H. Hetrick, S. H. Patterson, C. L. Neeley
1979, Open-File Report 79-526
The Macon-Gordon kaolin district is about 80 miles (130 km) southeast of Atlanta, Georgia. It extends across the boundary between, and includes parts of, the Piedmont and Atlantic Coastal Plain physiographic provinces. The rocks in the Piedmont are mainly intensely folded sericite schist and granite gneiss containing irregular masses of...
Organic carbon content of Devonian shale sequence sampled in drill cuttings from eighteen wells in western Pennsylvania
George Edwin Claypool, Allan W. Stone
1979, Open-File Report 79-1665
This report contains results of organic carbon analyses performed by Rinehart Laboratories, Inc., Arvada, Colorado, under contract to the U.S. Geological Survey. The analytical method employs chemical (chromic acid) oxidation of an acid solution containing the rock residue. The detailed analytical specifications are contained in the Rinehart proposal in response...
