Influence of a local source of DDT pollution on statewide DDT residues in waterfowl wings, northern Alabama, 1978-79
W. James Fleming, T. J. O'Shea
1980, Pesticides Monitoring Journal (14) 86-89
Heavy DDT contamination resulting from a former DDT manufacturing plant in northern Alabama has influenced statewide averages of DDT, DDE, and TDE residues in duck wings tested in the National Pesticide Monitoring Program. In states where contaminant levels in duck wings are high, residue analyses of wings categorized by finer...
Hydrologic and land-cover features of the Loxahatchee River Basin, Florida
Benjamin F. McPherson, Maryann Sabanskas
1980, Water-Resources Investigations Report 80-1109
This map report represents the first published product of the Loxahatchee River estuary assessment, and primarily fulfills the first objective as outlined in the report. It presents an overview of the major physical features of the basin and presents selected information on the U.S. Geological Survey assessment. The report includes...
Digital terrain tapes: user guide
Water Resources Division, U.S. Geological Survey
1980, Report
DMATC's digital terrain tapes are a by-product of the agency's efforts to streamline the production of raised-relief maps. In the early 1960's DMATC developed the Digital Graphics Recorder (DGR) system that introduced new digitizing techniques and processing methods into the field of three-dimensional mapping. The DGR system consisted of an...
Paleolimnology of two lakes in the Klutlan Glacier region, Yukon Territory, Canada
J.P. Bradbury, M.C. Whiteside
1980, Quaternary Research (14) 149-168
Lakes developed on progressively younger end moraines of the Klutlan Glacier were initially assumed to have originated shortly after moraine emplacement and to have persisted to the present. Limnological differences between lakes on old vs young moraines were thought to result from limnological maturation within the lakes and ponds themselves...
The origin and distribution of subbottom sediments in southern Lake Champlain
R. P. Freeman-Lynde, D. R. Hutchinson, D. W. Folger, B.H. Wiley, M.J. Hewett
1980, Quaternary Research (14) 224-239
Three units, correlatable with recent Lake Champlain, late-glacial marine Champlain Sea, and proglacial Lake Vermont sediments, have been identified from about 200 km of high-resolution seismic reflection profiles and eight piston cores collected in southern Lake Champlain. Lake Vermont deposits are nonfossiliferous and range from thin to absent nearshore and...
Folding and faulting of strain-hardening sedimentary rocks
Arvid M. Johnson
1980, Tectonophysics (62) 251-278
The question of whether single- or multi-layers of sedimentary rocks will fault or fold when subjected to layer-parallel shortening is investigated by means of the theory of elastic-plastic, strain-hardening materials, which should closely describe the properties of sedimentary rocks at high levels in the Earth's crust. The most attractive feature...
Identification of bedforms in lower Cook Inlet, Alaska
A.H. Bouma, M.L. Rappeport, R.C. Orlando, M. A. Hampton
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...
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...
Plasma corticosteroid and electrolyte dynamics of hybrid striped bass (white bass x striped bass) during netting and hauling
Davis K. B. Tomasso J. R. K. B., N. C. Parker
1980, Conference Paper, Proceedings of the World Mariculture Society
Striped bass hybrids (Morone chrysops female x Morone saxatilis male) confined in a net for 10 minutes had significantly elevated corticosteroid levels (24.2 † 5.4 μg/100 ml) and significant hyperchloremia (150.02 † 2.7 meq/liter), in comparison with baseline levels of 0.8 † 0.1 μg/100 ml and 132.6 † 1.5 meq/liter,...
EROS Data Center
Water Resources Division, U.S. Geological Survey
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...
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...
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...
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...
Effects of the proposed Prosperity Reservoir on ground water and water quality in lower Center Creek basin, Missouri
Wayne R. Berkas, James H. Barks
1980, Water-Resources Investigations Report 80-88
Effects of the proposed Prosperity Reservoir on ground water and water quality in lower Center Creek basin depend partly on the effectiveness of Grove Creek as a hydrologic boundary between the reservoir site and the Oronogo-Duenweg mining belt. Results of two dye traces indicate that Grove Creek probably is not...
Effects of urban runoff and wastewater effluent on Wilsons Creek and James River near Springfield, Missouri
Wayne R. Berkas
1980, Water-Resources Investigations Report 80-27
Statistical analysis on water-quality parameters from James River upstream and downstream from the confluence of Wilsons Creek shows a significant difference for all parameters except temperature and dissolved silica at the 0.05 probability level. Regression analysis shows correlation for discharge with dissolved sodium, dissolved chloride, and dissolved potassium, and for...
Sulfate reduction in ground water of southeastern Montana
William S. Dockins, G.J. Olson, Gordon A. McFeters, S.C. Turbak, Roger W. Lee
1980, Water-Resources Investigations Report 80-9
Ground water in southeastern Montana was investigated to determine if sulfide production was bacterially mediated. Sulfate—reducing bacteria were detected in 25 of 26 ground—water samples in numbers ranging from 2.0 x 101 to greater than 2.4 x 104 bacteria per 100 milliliters. Stable sulfur isotope fractionation studies indicate a biological...
Paleohydrology of the southern Great Basin, with special reference to water table fluctuations beneath the Nevada Test Site during the late(?) Pleistocene
Isaac Judah Winograd, Gene C. Doty
1980, Open-File Report 80-569
Knowledge of the magnitude of water-table rise during Pleistocene pluvial climates, and of the resultant shortening of groundwater flow path and reduction in unsaturated zone thickness, is mandatory for a technical evaluation of the Nevada Test Site (NTS) or other arid zone sites as repositories for high-level or transuranic radioactive...
