Dinkum Sands
Erk Reimnitz, Robin Ross, Peter W. Barnes
1980, Open-File Report 80-360
The State/Federal Beaufort Sea lease sale in December 1979 attracted over one billion dollars in bids. Tracts with the highest bids, and apparently with the highest oil potential, lie in the area south of Dinkum Sands, and within a three-mile radius of the shoal (Fig. 1). Jurisdiction over the tracts...
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...
Ground-water data for the Riley and Andrews Resource Areas, southeastern Oregon
Paul J. Townley, Constance M. Soja, W.C. Sidle
1980, Open-File Report 80-419
Appraisals of the resources of selected management areas in eastern Oregon are being made by the U.S. Bureau of Land Mangement. To provide needed hydrologic information, the Bureau of Land Management requested the U.S. Geological Survey to inventory ground-water data for the Riley and Andrews Resource Areas. The inventory included...
Scintillation detectors in gamma spectral logging; geometry, absorption and calibration
Ulrich Schimschal
1980, Open-File Report 80-688
The theory for the evaluation of the effects of geometry in gamma ray absorption is developed for cylindrical scintillation detectors as applicable to borehole gamma spectrometry. The results of a laboratory experiment are shown for comparison. A calibration procedure to determine detector efficiency is given for application to borehole probes....
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...
Land-surface subsidence in the Texas coastal region
Karl W. Ratzlaff
1980, Open-File Report 80-969
Land-surface subsidence has been mapped in the Houston-Galveston area and is known to have occurred in other areas within the Texas coastal region. Most of the subsidence has been caused by both the withdrawal of ground water and by the production of oil, gas, and associated ground water. Land-surface subsidence was...
Mid-Atlantic multichannel seismic-reflection profiles 14, 15, 16, and 17
John Stevens Schlee
1980, Open-File Report 80-624
The U. S. Geological Survey (USGS) is making available four multi­channel profiles collected by Teledyne Exploration in 1977 by means of a 48-channel streamer (3600 m long) and four airguns (2160 in). Profiles 15 and 16 were processed by.Teledyne Exploration and profiles 14 and 17 were processed on the Phoenix...
Geological Survey research 1980
Water Resources Division, U.S. Geological Survey
1980, Professional Paper 1175
A summary of recent significant scientific and economic results accompanied by a list of geologic, hydrologic, and cartographic investigations in progress....
Hydrology and water quality of the copper-nickel study region, northeastern Minnesota
Donald I. Siegel, Donald W. Ericson
1980, Open-File Report 80-739
Data were collected on the hydrology of the Copper-Nickel study region to identify the location and nature of groundwater resources, determine the flow characteristics and general quality of the major streams, and determine the potential effects of mining copper and nickel on the hydrologic stream. Groundwater generally occurs in local...
Hydrologic analysis of the proposed Badger-Beaver Creeks artificial-recharge project: Morgan County, Colorado
Alan W. Burns
1980, Water-Resources Investigations Report 80-46
A hydrologic analysis of the proposed Badger-Beaver Creeks artificial-recharge project in Morgan County, Colo., was made with the aid of three digital computer models: A canal-distribution model, a ground-water flow model, and a stream-aquifer model. Statistical summaries of probable diversions from the South Platte River based on a 27-year period...
Water-quality assessment of the Cypress Creek watershed, Warrick County, Indiana
Linda L. Bobo, Charles A. Peters
1980, Water-Resources Investigations Report 80-35
The U.S. Soil Conservation Service needs chemical, biological, microbiological, and hydrological data to prepare an environmental evaluation of the water quality in the Cypress Creek watershed, Warrick County, Ind., before plans can be devised to (1) improve water quality, (2) minimize flooding, (3) reduce sedimentation, and (4) provide adequate outlets...
Nitrogen in ground water and surface water from sewered and unsewered areas, Nassau County, Long Island, New York
Stephen E. Ragone, B. G. Katz, G.E. Kimmel, J.B. Lindner
1980, Water-Resources Investigations Report 80-21
Data on nitrogen in groundwater and surface waters in the sewered and unsewered parts of Nassau County were analyzed to evaluate the principal sources of nitrogen and to determine what factors significantly affect its concentration in the upper glacial aquifer and the underlying Magothy aquifer. Nitrate data for water samples...
Ground-water quality in North Idaho
D. J. Parliman, Harold R. Seitz, Michael L. Jones
1980, Open-File Report 80-596
From July 1977 to May 1978, water samples were collected from 116 wells north of the Palouse River in Idaho to define water-quality conditions, on a reconnaissance level, in major aquifers. Geologic and hydrologic data were combined with water-quality data to develop an understanding of factors affecting present and future...
