High-resolution seismic-reflection profiling data from the inner continental shelf of southeastern Massachusetts
Charles J. O’Hara
1980, Open-File Report 80-178
Six hundred-seventy kilometers of closely spaced high-resolution seismic-­reflection data have been collected from eastern Rhode Island Sound and Vineyard Sound, Mass, by the U.S. Geological Survey in cooperation with the Massachusetts Department of Public Works. These data were obtained during the June 1975 cruise of the R/V ASTERIAS as part...
Long-term highwall stability in the northwestern Powder River basin, Wyoming and Montana
William K. Smith
1980, Open-File Report 80-1229
Time-dependent behavior of natural and and excavated slopes in sedimentary rocks is a subject that is poorly understood at present but that is now an important consideration in the design, operation, and reclamation of energy-extraction facilities, in part because of the environmental considerations mandated by the Surface Mining Control and...
A one-dimensional, steady-state, dissolved-oxygen model and waste-load assimilation study for Little Lick and Big Lick Creeks, Blackford and Delaware counties, Indiana
James G. Peters, Charles G. Crawford, William G. Wilber
1980, Open-File Report 80-73
The Indiana State Board of Health is developing a State water-quality management plan that includes establishing limits for liquid wastes discharged into Indiana streams. A digital computer model was used to predict alternatives for future waste loadings on Little Lick and Big Lick Creeks that would be compatible with Indiana...
Simulated effects of ground-water development on potentiometric surface of the Floridan Aquifer, west-central Florida
William Edward Wilson, James M. Gerhart
1980, Open-File Report 79-1271
A digital model of two-dimensional ground-water flow was used to predict changes in the potentiometric surface of the Floridan aquifer, 1976-2000, in a 5,938-square-mile area of west-central Florida. In 1975, ground water withdrawn from the Floridan aquifer for irrigation, phosphate mines, other industries, and municipal supplies averaged about 649 million...
Seismic evidence for an extensive gas-bearing layer at shallow depth, offshore from Prudhoe Bay, Alaska
Gary Wynn Boucher, Erk Reimnitz, Edward W. Kempema
1980, Open-File Report 80-809
High resolution seismic reflection data recorded offshore from Prudhoe Bay, Alaska, were processed digitally to determine the reflectivity structure of the uppermost layers of the seafloor. A prominent reflector found at 27 m below the mudline (water depths 7-9 m) has a negative reflection coefficient greater than 0.5. The large...
Chemical analyses of stream deposits in the West Pioneer Mountains, Beaverhead County, Montana
David F. Siems, Eric P. Welsch, Wendy S. Speckman
1980, Open-File Report 80-309
The U.S. Geological Survey commenced a mineral-resource assessment of the West Pioneer Mountains, Montana in 1970. The study consists of coordinated geological, geochemical, and geophysical studies with the objective of evaluating the potential for mineral deposits in the area. The geochemical survey consists of the collection of bulk stream sediments...
Seismic damage assessment for high-rise buildings
Roger E. Scholl
1980, Open-File Report 81-381
The problem considered in this project, conducted by URS/John A. Blume & Associates, Engineers (URS/Blume), for the U.S. Geological Survey, is the identification, evaluation, and correlation of ground-motion and structural parameters in order to improve procedures for predicting dollar losses for high-rise structures damaged by earthquakes. Ground-motion data bases, analytical...
An oilspill risk analysis for the Kodiak Island (proposed sale 46) Outer Continental Shelf lease area
William B. Samuels, Kenneth J. Lanfear, Anastase Nakassis
1980, Open-File Report 80-175
An oilspill risk analysis was conducted to determine the relative environmental hazards of developing oil in different regions of the Kodiak Island Outer Continental Shelf (OCS) lease area. The study analyzed the probability of spill occurrences, likely paths of oil slicks, and locations of resources vulnerable to spilled oil. The...
An oilspill risk analysis for the Central and Northern California (proposed Sale 53) Outer Continental Shelf lease area
William B. Samuels, Kenneth J. Lanfear
1980, Open-File Report 80-211
An oilspill risk analysis was conducted to determine the relative environmental hazards of developing oil in different regions of the Central and Northern California Outer Continental Shelf (OCS) lease area. The study analyzed the probability of spill occurrences, likely paths of oil slicks, and locations of resources vulnerable to spilled...
Notes on the geology of Tibet and adjacent areas; report of the American plate tectonics delegation to the People's Republic of China
A.W. Bally, Clarence R. Allen, R.B. Geyer, W.B. Hamilton, C.A. Hopson, P.H. Molnar, J.E. Oliver, N.D. Opdyke, George Plafker, F.T. Wu
1980, Open-File Report 80-501
Mean water levels in wells across Georgia were from 3.03 feet higher to 11.67 feet lower in 1979 than in 1978, and in some areas were the lowest on record. Water levels in the principal artesian aquifer underwent a long-term decline during the period 1970-79. In some areas water levels...
