Single and superimposed bedforms: A synthesis of San Francisco Bay and flume observations
D. M. Rubin, D. S. McCulloch
1980, Sedimentary Geology (26) 207-231
Tidal currents with maximum depth-averaged velocities ranging up to 250 cm/sec have generated ripples, two- and three-dimensional sand waves, and upper flat beds on the floor of central San Francisco Bay. Determination of the hydraulic conditions under which the observed beds exist, indicates that the bed configuration at any point...
Identification of bedforms in lower Cook Inlet, Alaska

1980, Sedimentary Geology (26) 157-177
The seafloor of the central part of lower Cook Inlet, Alaska, is characterized by the presence of different sizes and types of bedforms. The bedforms in the sandy sediments include straight-crested to sinuous to lunate ripples, small, medium, and large sand waves, sand ridges, sand ribbons, and sand patches. In...
Geochronology of archean gneisses in the Lake Helen area, southwestern Big Horn Mountains, Wyoming
Joseph G. Arth, F. Barker, T. W. Stern
1980, Precambrian Research (11) 11-22
The Rb-Sr and U-Pb methods were used to study gneisses in the 712-minute">712-minute Lake Helen quadrangle of the Big Horn Mountains, Wyoming. Two episodes of magmatism, deformation and metamorphism occurred during the Archean. Trondhjemitic to tonalitic orthogneisses and amphibolite of the first episode (E-1) are cut...
First-order analysis of deformation of a thrust sheet moving over a ramp
Philip Berger, Arvid M. Johnson
1980, Tectonophysics (70) T9-T24
John L. Rich introduced the revolutionary concept that many folds in the Appalachian Mountains can be explained as superficial structures formed by passive translation of thrust blocks over ramps in detachment surfaces. The amount of layer-parallel shortening can be negligible in the formation of these folds. Rich primarily was concerned...

K.A. Kvenvolden, D.J. Blunt, M.A. McMenamin, S.E. Straham
1980, Physics and Chemistry of the Earth (12) 321-332
Concentrations of amino acids and their corresponding dl">dl enantiomeric ratios have been measured in shells of the bivalve mollusk Saxidomus from eleven localities, ranging in age from modern to probably more than 500,000 yr, along the Pacific coast of North America. Natural logarithms of amino acid concentrations correlate...
Preliminary evaluation of lake susceptibility to water-quality degradation by recreational use, Alpine Lakes Wilderness Area, Washington
Robert J. Gilliom, D. P. Dethier, S. A. Safioles, P.L. Heller
1980, Water-Resources Investigations Report 80-1124
The relative susceptibility of lakes in the Alpine Lakes Wilderness Area to water-quality degradation was evaluated from two perspectives: (1) water-quality sensitivity, which is the tendency of a lake 's water quality to degrade in response to pollutant loading, and (2) pollutant-loading likelihood, which is determined by the presence of...

1980, Report
The Earth Resources Observation Systems (EROS) Data Center, located in Sioux Falls, SD, is a data management, systems development, and research field center of the U.S. Geological Survey's National Mapping Division. The Center was established in the early 1970's to receive, process, and distribute data from National Aeronautics and Space...
Additional studies of competition and performance in OCS oil and gas sales, 1954-1975
Walter J. Mead, Philip Edward Sorensen
1980, Report
Economic rent is commonly defined in economics as any payment to a factor of production in excess of the minimum necessary to engage it in production. In the case of OCS lands owned by the federal government, the minimum supply price necessary to induce the federal government to lease production...
Handbook of acute toxicity of chemicals to fish and aquatic invertebrates : summaries of toxicity tests conducted at Columbia National Fisheries Research Laboratory, 1965-78
W. Waynon Johnson, Mack T. Finley
1980, Resource Publication 137
Acute toxicity is a major subject of research at Columbia National Fisheries Research Laboratory for evaluating the impact of toxic chemicals on fishery resources. The Laboratory has played a leading role in developing research technology for toxicity testing and data interpretation. In 1965-78, more than 400 chemicals were tested against...
Maps showing coal resources of the Crumpler quadrangle, Mercer, McDowell, and Wyoming Counties, West Virginia
Gary D. Stricker
1980, Miscellaneous Field Studies Map 1250
Coal GeologyThe Crumpler quadrangle lies in the Appalachian Plateaus province, with the coal bearing Pocahontas and New River Formations of Pennsylvanian age having a gentle dip toward the northwest. Coal bed maps were prepared (figures 1-7) and resources were estimated (table 1) for seven of the many coal beds in...
Selected water-level records for Oklahoma, 1979-80
Willard B. Mills, Dannie E. Spiser
1980, Open-File Report 80-975
A systematic program to collect water-level records in Oklahoma began in 1937. The objectives of this program are (1) to provide long-term records of water-level fluctuations in representative wells, (2) to facilitate the prediction of water-level trends and indicate future availability of ground-water supplies, and (3) to provide information for...
The Rocky Mountain population of the western Canada goose: Its distribution, habitats, and management
William B. Krohn, Elwood G. Bizeau
1980, Special Scientific Report - Wildlife 229
The western Canada goose (Branta canadensis moffitti) was divided into a Rocky Mountain population (RMP) and a Pacific population (PP) on the basis of band recovery patterns examined in this study and recovery data from other investigators. Habitat information obtained from nine cooperating wildlife agencies within the RMP's range provided...

Breeding biology and relation of pollutants to black skimmers and gull-billed terns in South Carolina
Lawrence J. Blus, Charles J. Stafford
1980, Special Scientific Report - Wildlife 230
The breeding biology and relation of pollutants to black skimmers (Ryn chops niger) and gull-billed terns (Gelochelidon nilotica) were investigated in South Carolina from 1969 through 1975. With few exceptions, the two species nested together in colonies located on barrier islands. We located 10 colonies, 7 of which were on...
