Ground-water data for Michigan, 1981
G.C. Huffman
1982, Open-File Report 82-754
This report summarizes data on water levels in 124 observation wells and provides information on well locations, depths, altitudes, and aquifers that they tap. Tabulated data include extremes of water levels for 1981 and for the period of record; pumpage of most major groundwater users in the State; and quality...
Continuous water sampling and water analysis in estuaries
L. E. Schemel, L.A. Dedini
1982, Open-File Report 82-551
Salinity, temperature, light transmission, oxygen saturation, pH, pCO2, chlorophyll a fluorescence, and the concentrations of nitrate, nitrite, dissolved silica, orthophosphate, and ammonia are continuously measured with a system designed primarily for estuarine studies. Near-surface water (2-m depth) is sampled continuously while the vessel is underway; on station, water to depths...
Application of computer graphics to generate coal resources of the Cache coal bed, Recluse geologic model area, Campbell County, Wyoming
G. B. Schneider, S.S. Crowley, M.A. Carey
1982, Open-File Report 82-402
Low-sulfur subbituminous coal resources have been calculated, using both manual and computer methods, for the Cache coal bed in the Recluse Model Area, which covers the White Tail Butte, Pitch Draw, Recluse, and Homestead Draw SW 7 1/2 minute quadrangles, Campbell County, Wyoming. Approximately 275 coal thickness measurements obtained from...
Two BASIC computer programs for the determination of in situ stresses using the CSIRO hollow inclusion stress cell and the USBM borehole deformation gage
W. K. Smith
1982, Open-File Report 82-489
The mathematical method of determining in-situ stresses by overcoring, using either the U.S. Bureau of Mines Borehole Deformation Gage or the Commonwealth Scientific and Industrial Research Organisation Hollow Inclusion Stress Cell, is summarized, and data reduction programs for each type of instrument, written in BASIC, are presented. The BASIC programs...
Dissolved-solids concentrations of ground water in the Sacramento Valley, California
Ronald P. Fogelman
1982, Hydrologic Atlas 645
The general quality of the ground water in the Sacramento Valley , Calif., in terms of dissolved-solids concentration is considered good for irrigation, domestic, and most other uses. This map shows the distribution of dissolved-solids concentrations and is based on about 1,330 chemical analyses collected from about 900 wells between...
Data on subsurface storage of liquid waste near Pensacola, Florida, 1963-1980
R. W. Hull, J.B. Martin
1982, Open-File Report 82-689
Since 1963, when industrial waste was first injected into the subsurface in northwest Florida, considerable data have been collected relating to the geochemistry of subsurface waste storage. This report presents hydrogeologic data on two subsurface waste storage. This report presents hydrogeologic data on two subsurface storage systems near Pensacola, Fla.,...
GLORIA sidescan and seismic data collected by the DESV STARELLA along the continental slope and upper continental rise of the Eastern United States in 1979
Kathryn M. Scanlon
1982, Open-File Report 82-1095
A cruise on the- DESV STARELLA was conducted between October 23. 1979, and November 8, 1979, by the U.S. Geologic.al Survey (USGS) in cooperation with the United Kingdom's Institute of Oceanographic Sciences (IOS). The purpose of the study was to gain an overview of the morphology of large areas of...
Zeolites in the Pine Ridge Indian Reservation, South Dakota
William H. Raymond, Alfred L. Bush, Arthur J. 3rd Gude 3rd
1982, Open-File Report 82-959
Zeolites of possible commercial value occur in the Brule Formation of Oligocene age and the Sharps Formation (Harksen, 1961) of Miocene age which crop out in a wide area in the northern part of the Pine Ridge Indian Reservation. The thickness of the zeolite-bearing Interval and the extent of areas...
Potential impacts of a proposed reservoir on hydrologic and water-quality conditions in Little Rush Creek watershed, Fairfield County, Ohio
Janet Hren, R.L. Jones
1982, Open-File Report 82-109
Water-quality and discharge measurements were made at three sites on Indian Run and one site on Little Rush Creek between February and December, 1979. Indian Run was observed above and below the U.S. Soil Conservation Service Reservoir, VI-D. Little Rush Creek was observed 1.1 miles downstream from the proposed U.S....
