Determination and analysis of bearing capacity of calcarenites off the Florida Keys
J.S. Booth, R.A. Farrow, G.N. Wiley, R.C. Circe
1982, Open-File Report 82-309
A specially designed instrument was used to determine the in situ bearing capacity at 12 sites in the carbonate sand seaward of the Florida Keys. The resulting data set not only represents unique information in such an environment, but also provided an opportunity to determine whether bearing capacity is controlled...
Index of hydrologic data for selected sites in Broward County, Florida, 1939-80
R.S. Sonenshein, J.E. Fish, C. R. Causaras, D.M. Poore
1982, Open-File Report 82-920
A comprehensive assessment of the surficial aquifers, of southeast Florida, including the Biscayne aquifer, was begun in 1979 by the U.S. Geological Survey, in cooperation with the South Florida Water Management District. In the initial phase of the study, an inventory was made of existing data available in the files...
Sinkhole development resulting from ground-water withdrawal in the Tampa area, Florida
William C. Sinclair
1982, Water-Resources Investigations Report 81-50
The area of municipal well fields on the Gulf Coastal Plain north of tampa, Fla., is densely pitted with natural sinkholes and sinkhole lakes that have resulted from collapse of surficial sand and clay into solution cavities in the underlying carbonate rocks of the Floridan aquifer. Although solution of the...
Mineralization and other geologic factors related to the Morrison Formation in particular the northern two-thirds of the Colorado Plateau region; basic data and factor-analysis results
Robert Allen Cadigan
1982, Open-File Report 82-1130
A vanadium-mercury mineralization factor and five other significant geologic factors were determined by multivariate factor analysis of data for Morrison Formation rock samples from the Colorado Plateau region. The data presented in the report were obtained from an agglomeration of 876 samples which yielded a correlation matrix of 44 variables....
Geophysical studies of the Syncline Ridge area, Nevada Test Site, Nye County, Nevada
D.B. Hoover, W. F. Hanna, L. A. Anderson, V. J. Flanigan, L. W. Pankratz
1982, Open-File Report 82-145
A wide variety of geophysical methods were employed to study a proposed nuclear waste site at Syncline Ridge on the Nevada Test Site, Nev. The proposed site was believed to be a relatively undisturbed synclinal structure containing a thick argillite unit of Misslsslppian age, the Eleana Formation unit J, which...
Ground water and geology of Marquette County, Michigan
C. J. Doonan, J. L. Van Alstine
1982, Open-File Report 82-501
Ground-water resources of Marquette County are about evenly divided between bedrock aquifers and aquifers in glacial deposits. In the northern and the extreme southern parts of the county, most wells are completed in bedrock at depths less than 100 feet. In the central part, most wells are completed in glacial...
Water-quality characteristics of six small, semiarid watersheds in the Green River coal region of Colorado
John T. Turk, Randolph S. Parker
1982, Water-Resources Investigations Report 81-19
Analysis of major and trace constituents in streams flowing through six semiarid watersheds indicates that the stream chemistry is characterized by saturation with respect to common carbonate minerals (calcium, magnesium, iron, manganese, and lead). The solubility of the carbonate minerals may be a major control on the absolute and relative...
Water resources data, Louisiana, water year 1982: Volume 1. Central and northern Louisiana
D.D. Carlson, G.R. Stallworth, L.J. Dantin, C.G. Stuart
1982, Water Data Report LA-82-1
Water resources data for the 1982 water year for Louisiana consist of records of stage, discharge, and water quality of streams; stage, contents, and water quality of lakes and reservoirs; and water levels and water quality of ground water. This report, in two volumes, contains records for water discharge at...
Altitude and configuration of the water table in the High Plains Aquifer in Kansas, 1965
Marilyn E. Pabst, Lloyd E. Stullken
1982, Open-File Report 82-449
The High Plains aquifer in Kansas is a part of a regional system that extends South Dakota to Texas. The aquifer in Kansas underlies an area of 31,000 square miles in the western and south-central part. This aquifer is a hydraulically connected assemblage of unconsolidated water-bearing deposits of Tertiary and...
Quality of water in Luxapallia Creek at Columbus, Mississippi
Stephen J. Kalkhoff
1982, Open-File Report 82-373
A quality-of-water study was conducted on September 9-12, 1979, on Luxapallila Creek and its tributaries, Magby and McCrary Creeks. The short term study indicated that the water in Luxapallila, Magby, and McCrary Creeks is suitable for many purposes.The dissolved-oxygen concentration, temperature, and pH of the water in Luxapallila Creek changed...
New papers related to remote sensing of the earth
A. P. Colvocoresses, F.J. Doyle
1982, Open-File Report 82-237
Worldwide experience of many individuals and organizations with remote sensing data acquired from space, primarily Landsat-1, -2, and -3, has demonstrated its utility for land use classification, agricultural assessment, energy and resource exploration, and many other applications. There has been some reluctance to adopt these systems in operational programmes because...
Geochemical reconnaissance for uranium occurrences in the Notch Peak intrusive area, House Range, Millard County, Utah
R. A. Cadigan, Keith Robinson
1982, Open-File Report 82-491
Samples collected from the contact metamorphic zone of the Notch Peak intrusive area, House Range, Millard County, Utah, indicate the occurrence of low-grade uranium and thorium ore. Maximum abundances in the altered mineralized rocks in the contact zone are 450 ppm uranium and 480 ppm thorium. Interpretation of factor analysis...
The effects of channel excavation on water-quality characteristics of the Black River and on ground-water levels near Dunn, North Carolina
C.E. Simmons, S.A. Watkins
1982, Water-Resources Investigations Report 82-4083
During 1976-81 data were collected at three sites on the Black River near Dunn, N.C., to define the effects of channel excavation on stream quality and on ground-water levels in nearby areas. One of the data sites was located upstream from the five-mile long excavated reach and served as a...
The economic feasibility of operational earth sensing from space
Alden P. Colvocoresses
1982, Open-File Report 82-250
Earth-sensing satellites designed to follow Landsat involve spatial resolution in the order of 10 to 30 m as compared to the 80 m of the Landsat Multispectral Scanner (MSS). At these higher resolutions such satellites will perform inspection functions of high importance to government agencies and which are beyond the...
