Water-level maps of the alluvial aquifer, northwestern Mississippi, September 1982
Daphne Darden
1983, Water-Resources Investigations Report 83-4133
Water levels were measured in about 500 wells in the Mississippi River valley alluvial aquifer in northwestern Mississippi during September 13-24, 1982. The water-level change from September 1981 to September 1982 showed some recovery, but the depth-to-water map showed areas of continual water-level decline in the central part of the...
Base flow and ground water in upper Sweetwater Valley, Tennessee
R. D. Evaldi, J.G. Lewis
1983, Water-Resources Investigations Report 83-4068
Base flow measurements showed interbasin transfer of water among sub-basins of upper Sweetwater Valley. In general, topographically higher sub-basins have deficient surface outflow unless significant spring flow occurs in the basin. Topographically lower areas adjacent to the main channel of Sweetwater Creek generally have surplus flow. Major flow surpluses were...
Results of a test well in the Nanafalia Formation near Melvin, Choctaw County, Alabama
M. E. Davis, A.K. Sparkes, B.S. Peacock
1983, Water-Resources Investigations Report 82-4108
Test drilling at Melvin, Choctaw County, Alabama, discloses that the Nanafalia Formation (Paleocene) contains freshwater in sand at a distance of 25 miles downdip from the outcrop area. A nearby fault on the north side of Gilberttown-Pickens fault zone does not appear to affect either the head or the water...
Ground-water data for Michigan 1982
G.C. Huffman
1983, Open-File Report 83-753
Water levels, locations, depths, and aquifers tapped are given for 117 observation wells. Tabulated data include extremes of water levels for 1982 and for the period of record, pumpage of most major ground-water users in the State, and quality data on selected wells. The largest reported user of ground-water, the...
Principal facts of gravity stations with gravity and magnetic profiles from the Southwest Nevada Test Site, Nye County, Nevada, as of January, 1982
P.E. Jansma, D.B. Snyder, David A. Ponce
1983, Open-File Report 82-1041
Three gravity profiles and principal facts of 2,604 gravity stations in the southwest quadrant of the Nevada Test Site are documented in this data report. The residual gravity profiles show the gravity measurements and the smoothed curves derived from these points that were used in geophysical interpretations. The principal facts...
Geologic interpretation of geophysical data for the Wadi al Jarir and Al Jurdhawiyah quadrangles, sheets 25/42 C and D, Kingdom of Saudi Arabia
M. Dean Kleinkopf, J. C. Cole
1983, Open-File Report 83-371
Interpretations of aeromagnetic and gravity data made in support of geologic mapping clearly outline the near-surface shape of Proterozoic granitic units in the Wadi al Jarir (25/42 C) and Al Jurdhawiyah (25/42 D) 1:100,000-scale quadrangles of the northern part of the Arabian Shield. The aeromagnetic data show marked correlation with...
Preliminary geomagnetic data, College Observatory, Fairbanks, Alaska: September 1983
John B. Townshend, J.E. Papp, E.A. Sauter, L.Y. Torrence, P.A. Franklin
1983, Open-File Report 83-300-I
The preliminary geomagnetic data included here is made available to scientific personnel and organizations, as part of a cooperative effort and on a data exchange basis because of the early need by some users. To avoid delay, all of the data is copied from original forms processed at the observatory;...
Potentiometric surfaces on Long Island, New York -- A bibliography of maps
D. A. Smolensky
1983, Open-File Report 84-70
Historic water-level records form a major basis for ground-water investigations and water-management decisions on Long Island. Potentiometric-surface maps, one of the major sources of historic data, are scattered within the literature or are available only through the publisher or sponsoring agency. This report presents a comprehensive list of available water-table...
Surface water and climatologic data, Salt Lake County, Utah, water year 1981, with selected data for water years 1980 and 1982
H.F. McCormack, R.C. Christensen, D. W. Stephens, G. E. Pyper, J. F. Weigel, L.S. Conroy
1983, Open-File Report 83-694
This report contains precipitation, atmospheric-deposition, water- discharge and water-quality data collected in Salt Lake County as part of two investigations by the U.S. Geological Survey. The purpose of this report is to release data collected mainly during the 1981 water year. Selected data collected during the 1980 water year not...
Geothermal resources of the western arm of the Black Rock Desert, northwestern Nevada: Part I, geology and geophysics
Donald H. Schaefer, Alan H. Welch, Douglas K. Mauzer
1983, Open-File Report 81-918
Studies of the geothermal potential of the western arm of the Black Rock Desert in northwestern Nevada included a compilation of existing geologic data on a detailed map, a temperature survey at 1-meter depth, a thermal-scanner survey, and gravity and seismic surveys to determine basin geometry. The temperature survey showed...
Gravity survey of Dixie Valley, west-central Nevada
Donald H. Schaefer
1983, Open-File Report 82-111
Dixie Valley, a northeast-trending structural trough typical of valleys in the Basin and Range Province, is filled with a maximum of about 10,000 feet of alluvial and lacustrine deposits , as estimated from residual-gravity measurements obtained in this study. On the basis of gravity measurements at 300 stations on nine...
Preliminary plasma spectrometric analyses for selected elements in some geothermal waters from Cerro Prieto, Mexico
J.W. Ball, E. A. Jenne
1983, Water-Resources Investigations Report 83-4056
As part of a cooperative study with Dr. Alfred Truesdell, water samples collected from geothermal power production wells at Cerro Prieto, Mexico, were analyzed for selected elements by d.c. argon plasma emission spectroscopy. Spectral interferences due to the presence of high concentrations of Ca, Si, Na and K in these...
