The magnetic charts of the United States for Epoch 1975
Eugene B. Fabiano, W. J. Jones, Norman W. Peddie
1979, Circular 810
Approximately 24,000 measurements taken from 1900 to 1974 were analyzed by least-squares methods to produce a series of five magnetic charts of the United States for 1975. A feature of the analysis, differing from techniques used for previous editions of the national chart, is that analytic models define the regional...
The Citronelle aquifers in Mississippi
E. H. Boswell
1979, Water-Resources Investigations Report 78-131
The Citronelle aquifers consist of sand and gravel of Pliocene age that forms a discontinuous outcrop area of about 6,000 square miles in southern Mississippi. The beds dip to the south at an average rate of about 6 feet per mile. The unconfined aquifers are used mostly for domestic and...
Estimating the gas and dye quantities for modified tracer technique measurements of stream reaeration coefficients
R. E. Rathbun
1979, Water-Resources Investigations Report 79-27
Measuring the reaeration coefficient of a stream with a modified tracer technique has been accomplished by injecting either ethylene or ethylene and propane together and a rhodamine-WT dye solution into the stream. The movement of the tracers through the stream reach after injection is described by a one-dimensional diffusion equation....
Description of dredge samples from the Bering Sea continental margin
Michael S. Marlow, Alan K. Cooper, David W. Scholl, Tracy L. Vallier, Hugh McLean
1979, Open-File Report 79-1139
During 1978 twenty dredge sites were occupied and successfully dredged from the R.V. S.P. LEE along the eastern Bering Sea continental margin (Fig. 1). A total of several tons of rock were collected using a chain-bag dredge. Samples were recovered in water depths ranging from 750 to 2,750 meters from...
Map showing ground-water conditions in the Virgin River, Grand Wash, and Shivwits areas, Mohave County, Arizona, 1976
G. W. Levings, C. D. Farrar
1979, Water-Resources Investigations Report 79-57
The Virgin River, Grand Wash, and Shivwits areas include about 3 ,250 square miles in northwestern Arizona. Ground water is obtained mainly from the alluvium, conglomerate, and basalt; however, several other formations yield small amounts of water to some wells. In the Virgin River area, most wells are less than...
Assessment of geothermal resources of the United States: 1978
L.J. Patrick Muffler
1979, Circular 790
The geothermal resource assessment presented in this Circular is a refinement and updating of USGS Circular 726. Nonproprietary information available in June 1978 is used to assess geothermal energy in the ground and, when possible, to evaluate the fraction that might be recovered at the surface. Five categories of geothermal...
