Single-channel seismic-reflection profiles and sidescan sonar records collected during May 15-20, 1978, on the southern New England continental shelf
David C. Twichell
1980, Open-File Report 80-177
The U.S. Geological Survey completed a cruise aboard the R/V CAPE HENLOPEN during May 15-20, 1978, to map the surface character, thickness and extent of the fine-grained.sediment deposit that covers an area 100 x 200 km on the southern New England Continental Shelf. The study area lies between Great South...
A water-quality monitoring network for Vallecitos Valley, Alameda County, California
C. D. Farrar
1980, Water-Resources Investigations Report 80-59
A water-quality monitoring network is proposed to detect the presence of and trace the movement of radioisotopes in the hydrologic system in the vicinity of the Vallecitos Nuclear Center. The source of the radioisotopes is treated industrial wastewater from the Vallecitos Nuclear Center that is discharged into an unnamed tributary...
Analyses of water, core material, and elutriate samples collected near Sicily Island, Louisiana (Sicily Island area levee project)
Dennis K. Demcheck, Alton J. Dupuy
1980, Open-File Report 80-434
Samples consisting of composited core material were collected from five areas by the U.S. Army Corps of Engineers and analyzed by the U.S. Geological Survey to provide data on the impact of proposed channel excavation and levee construction in the Sicily Island area, Louisiana. Samples of receiving water from the...
Water resources data for Massachusetts and Rhode Island, water year 1979
Water Resources Division, U.S. Geological Survey
1980, Water Data Report MA-RI-79-1
Water-resources data for the 1979 water year for Massachusetts and Rhode Island consist of records of stage, discharge, and water quality of streams; contents of lakes and reservoirs; and ground-water levels. This report contains discharge records for 102 gaging stations, month end contents for 30 lakes and reservoirs, water quality...
Minisparker profiles from Jeffreys Ledge and adjacent areas in the western Gulf of Maine
Diane M. Eskenasy, Norman G. Bailey
1980, Open-File Report 80-320
A total of 250 kilometers of single-channel seismic-reflection data (28 minisparker profiles) were collected in the coastal waters of Massachusetts, north of and immediately south of Cape Ann, and on the western flank of Jeffreys Ledge, western Gulf of Maine, during the September 1978 cruise of the R/V ASTERIAS. The...
Analysis of borehole geophysical data in an evaporite sequence at Salt Valley, Utah
Jeffrey J. Daniels, James H. Scott, Robert J. Hite
1980, Open-File Report 80-525
Interpretation of the lithology of an interbed sequence (thin-bedded sediments between thick layers of salt) is often difficult due to the presence of dolomitic sandstones and halite inclusions. The most useful well logging measurements in an evaporite sequence are gamma-ray, neutron-neutron, density, and acoustic velocity. The high resistivity of salt...
Physical environment and hydrologic characteristics of coal-mining areas in Missouri
J. E. Vaill, James H. Barks
1980, Water-Resources Investigations Report 80-67
Hydrologic information for the north-central and western coal-mining regions of Missouri is needed to define the hydrologic system in these areas of major historic and planned coal development. This report describes the physical setting, climate, coal-mining practices, general hydrologic system, and the current (1980) hydrologie data base in these two...
Water resources data for Louisiana, water year 1980: Volume 2. Southern Louisiana
Water Resources Division, U.S. Geological Survey
1980, Water Data Report LA-80-2
Water resources data for the 1980 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 three volumes, contains records for water discharge at...
Thermal modeling of flow in the San Diego Aqueduct, California, and its relation to evaporation
Harvey E. Jobson
1980, Professional Paper 1122
The thermal balance of the 26-kilometer long concrete-lined San Diego Aqueduct, a canal in southern California, was studied to determine the coefficients in a Dalton type evaporation formula. Meteorologic and hydraulic variables, as well as water temperature, were monitored continuously for a 1-year period. A thermal model was calibrated by...
Revised nomenclature and stratigraphic relationships of the Fredericksburg Complex and Quantico Formation of the Virginia Piedmont
Louis Pavlides
1980, Professional Paper 1146
The Fredericksburg Complex, in part a migmatitic terrane in northeast Virginia, is subdivided on the basis of lithology, as well as aeromagnetic and aeroradiometric data, into two metamorphic suites. These suites are separated by the northeast-trending Spotsylvania lineament, a rectilinear geophysical feature that is probably the trace of an old...
Water quality of four lakes in Lakeville, Minnesota
L. H. Tornes, M.R. Have
1980, Water-Resources Investigations Report 80-66
Water-quality characteristics were determined for four selected lakes to provide background data for evaluating changes that may occur in the lakes because of urbanization. Precipitation of calcium carbonate is suggested by high pH values and a decrease in the calcium concentration when magnesium, sodium, and chloride concentrations increase. Pollution is...
Summaries of data on and lists of references to metallic and selected nonmetallic mineral deposits in fifteen quadrangles in southwestern and west-central Alaska
Edward Huntington Cobb
1980, Open-File Report 80-909
These summaries of data on metallic and selected nonmetallic mineral occurrences and lists of selected references to them in Geological Survey, U.S. Bureau of Mines, and State of Alaska Division of Geological and Geophysical Surveys (and predecessor State and Territorial agencies) reports and maps released before Jan. 1, 1980, and...
Ground-water resources investigation in the Amran Valley, Yeman Arab Republic
G. Chase Tibbitts, James Aubel
1980, Open-File Report 80-774
A program of hydrologic studies and exploratory drilling was conducted intermittently between 1974 and 1978 to evaluate the water-bearing properties of the unconsolidated alluvial sediments and associated rocks in the semi-arid Amran Valley basin, an 800-square-kilometer area in north-central Yemen Arab Republic. Inventory data from 395 wells were compiled, observation...
