Storage and retrieval of ground-water data at the U.S. Geological Survey
Maria W. Mercer, Charles O. Morgan
1982, Circular 856
The U.S. Geological Survey maintains a computerized Ground-Water Site-Inventory (GWSI) file that contains information about wells and springs at sites from all States of the United States. This file contains data collected by U.S. Geological Survey personnel and personnel of cooperating State, local and Federal agencies. The file is easily...
Water use in Wisconsin, 1979
C.L. Lawrence, B.R. Ellefson
1982, Water-Resources Investigations Report 82-444
This report summarizes the uses of water in Wisconsin for 1979, except aesthetics, navigation, and recreational use. The greatest single use of water, an instream use, was for hydroelectric power production. About 26 trillion gallons, or 93 percent, was used for this purpose. Of the other 7 percent where water is...
Effects of volcanic ash on the benthic environment of a mountain stream, northern Idaho
S.A. Frenzel
1982, Water-Resources Investigations Report 82-4106
The May 18, 1980, eruption of Mount St. Helens deposited about 15 millimeters of volcanic ash on the Big Creek basin in northern Idaho. Much of the uncompacted ash remained on hillsides a year after the eruption. Physical and chemical analyses of water samples from Big Creek collected from December...
Estimates of vertical hydraulic conductivity and regional ground-water flow rates in rocks of Jurassic and Cretaceous age, San Juan Basin, New Mexico and Colorado
P. F. Frenzel, F. P. Lyford
1982, Water-Resources Investigations Report 82-4015
The San Juan structural basin northwestern New Mexico was modeled in three dimensions using a finite-difference, steady-state model. The modeled space was divided into seven layers of square prisms that were 6 miles on a side in the horizontal directions. In the vertical direction, the layers of prisms ranged in...
Progress report on lithium-related geologic investigations in Bolivia
J.R. Davis, K. A. Howard, S.L. Rettig, R. L. Smith, G. E. Ericksen, Francois Risacher, Hugo Alarcon, Ricardo Morales
1982, Open-File Report 82-782
The September 1, 1981, Samoa Islands Region earthquake occurred at the extreme northern end of the Tonga arc in a region where the Pacific plate may be disjointed along a hinge fault. In the last 50 years, magnitude 7 or greater earthquakes have occurred in this region on the average...
Thermal regime of permafrost at Prudhoe Bay, Alaska
A.H. Lachenbruch, J.H. Sass, B.V. Marshall, T. H. Moses Jr.
1982, Open-File Report 82-535
Temperature measurements through permafrost in the oil field at Prudhoe Bay, Alaska, combined with laboratory measurements of the thermal conductivity of drill cuttings permit an evaluation of in situ thermal properties and an understanding of the general factors that control the geothermal regime. A sharp contrast in temperature gradient at...
Geoindex

Quality assurance practices for the chemical and biological analyses of water and fluvial sediments
Linda C. Friedman, David E. Erdmann
1982, Techniques of Water-Resources Investigations 05-A6
This chapter contains practices used by the U.S. Geological Survey to assure the quality of analytical data for water, fluvial sediment, and aquatic organisms. These practices are directed primarily toward personnel making water quality measurements. Some detail specific quality control techniques, others document quality assurance procedures being used by the...
Environmental geology of Harrison Bay, northern Alaska
J.D. Craig, G. P. Thrasher
1982, Open-File Report 82-35
The surficial and shallow subsurface geology of Harrison Bay on the Beaufort Sea coast was mapped as part of the U.S. Geological Survey's prelease evaluation for Outer Continental Shelf (OCS) Oil and Gas Lease Sale 71. During the 1980 summer season, approximately 1600 km of multisensored, high-resolution geophysical profile data...
