Records of water levels in unconsolidated deposits in eastern South Dakota
Wendell L. Bradford
1981, Open-File Report 81-924
This report, prepared in cooperation with the South Dakota Department of Water and Natural Resources and the South Dakota Geological Survey, contains a tabulation of water levels measured by the U.S. Geological Survey (USGS) and State agencies.Wells owned by the U.S. Bureau of Reclamation (USBR) were measured as part of...
Water-level records for the Big Sioux aquifer, Minnehaha County, South Dakota
Wendell L. Bradford
1981, Open-File Report 81-222
This report contains a tabulation of water levels in wells tapping the Big Sioux aquifer in Minnehaha County, S. Dak. Included is a compilation of all water levels in 43 wells measured by the U.S. Geological Survey and State agencies during the period 1957-80. The data are presented in tabular...
Water levels in bedrock aquifers in South Dakota
Wendell L. Bradford
1981, Open-File Report 81-627
This report on water levels in bedrock aquifers in South Dakota is the result of a continuing investigation begun in 1959 by the U.S. Geological Survey in cooperation with the South Dakota Department of Water and Natural Resources. The purpose of the investigation is to collect data on the artesian...
Real time monitoring of radon as an earthquake precursor in Iceland
Wallace S. Broecker, J.C. Goddard, Egill Hauksson
1981, Open-File Report 81-877
We report radon data collected during 1980 from geothermal wells in Iceland. Discrete radon samples are being collected weekly from nine stations in the Southern Iceland Seismic Zone (SISZ) and two stations in the Northern Iceland-Tjornes Fracture Zone (TFZ) to determine the potential for earthquake prediction. We also monitor volume...
Alluvial aquifer of the Cache and St. Francis River basins, northeastern Arkansas
Matthew E. Broom, Forest P. Lyford
1981, Open-File Report 81-476
The alluvial aquifer underlies about 9,000 square miles of the study area. Well yields from the aquifer commonly are from 1,000 to 2,000 gallons per minute. Flow toward the main area of pumping stress is eastward from the Cache River and westward from the St. Francis River. The Memphis aquifer...
Tabulation of the ostracode assemblages and associated organisms from selected bottom grab samples taken in the northeast Gulf of Alaska, F.R.S. Townsend Cromwell Cruise IGAL-75-KC, 1975
Elisabeth M. Brouwers
1981, Open-File Report 81-1314
The U.S. Geological Survey is conducting studies of the Alaskan continental shelf, identifying areas and processes of geological hazard that may affect resource development offshore. These hazards include areas of rapid accumulation of unconsolidated sediment, areas of intense erosional activity, and regions of submarine sliding and slumping; shallow faults are...
Simulated hydrologic effects of possible ground-water and surface-water management alternatives in and near the Platte River, south-central Nebraska
Alan W. Burns
1981, Open-File Report 81-1116
Digital computer models were developed and used to simulate the hydrologic effects of hypothetical water-management alternatives on the wetland habitat area near Grand Island, Nebr. Areally distributed recharge to and discharge from the aquifer system adjacent to the Platte River between Overton and Grand Island were computed for four hypothetical...
Plankton studies in San Francisco Bay; II, Phytoplankton abundance and species composition, July 1977-December 1979
Raymond L. J. Wong, James E. Cloern
1981, Open-File Report 81-214
Data are presented on the phytoplankton species composition and abundance in San Francisco Bay from July 1977 through December 1979. Phytoplankton identification and enumerations were made at selected stations. Sample collections were made at selected stations in the main channel of the Bay from Rio Vista on the Sacramento River...
