Multichannel seismic reflection and sonobuoy refraction data in the outer southern California Borderland
James K. Crouch, M.L. Holmes, T. H. McCulloh, A. T. Long, R.H. Brune
1978, Open-File Report 78-706
During the L1-78-SC cruise of the USGS research vessel S. P. Lee (April 25 - May 11, 1978) seven sonobuoy profiles and 200 km of 24-channel seismic reflection data were recorded in the outer southern California Continental Borderland. These data were obtained, at the request of the Deep Sea Drilling...
Technique for estimating magnitude and frequency of floods in Delaware
R.H. Simmons, D.H. Carpenter
1978, Water-Resources Investigations Report 78-93
A flood-estimating method is presented which applies to drainage basins in Delaware without urban development and covers selected recurrence intervals from 2 to 100 years. The method was developed by multiple-regression techniques. The State is divided into two regions and sets of equations for calculating peak discharges based on physical...
Uranium values from ion-filter water sampling compared with values from bulk-water sampling
Robert Allen Cadigan, J. Karen Felmlee
1978, Open-File Report 78-472
Analytical values of uranium from well water sampled by means of ion-filters were compared with analytical values of the same water sampled by the standard bulk (1-liter) water-sampling technique (Brown, Skougstad and Fishman, 1970). A fluorometric extraction method of analysis was used on both sets of samples. Duplicate samples from...
Cross-section data for selected Puerto Rico streams
Eloy Colon-Dieppa, Ralph Gonzalez
1978, Open-File Report 78-882
The data presented in this report were originally collected for the purpose of delineating the inundation which could be expected by floods of selected magnitudes. As this study progressed, it became apparent that further analysis would be a duplication of effort as the United States Flood Insurance Administration was requiring...
Water-table map of Milwaukee County, Wisconsin
Marvin G. Sherrill, J.J. Schiller, John R. Erickson
1978, Water-Resources Investigations Report 79-40
A map (scale 1:100,000) of the water table in Milwaukee County in southeastern Wisconsin was prepared using water levels from more than 135 wells. The work was done as a cooperative project between the U.S. Geological Survey and the Southeastern Wisconsin Regional Planning Commission. The map shows the altitude of...
The hydrothermal system of Long Valley Caldera, California
M.L. Sorey, Robert Edward Lewis, F. H. Olmsted
1978, Professional Paper 1044-A
Long Valley caldera, an elliptical depression covering 450 km 2 on the eastern front of the Sierra Nevada in east-central California, contains a hot-water convection system with numerous hot springs and measured and estimated aquifer temperatures at depths of 180?C to 280?C. In this study we have synthesized the results...
Water quality in the Ozark National Scenic Riverways, Missouri
James H. Barks
1978, Water Supply Paper 2048
The Current River and its principal tributary, Jacks Fork, are the Ozark National Scenic Riverway's primary natural features. About 60 percent of the baseflow in the two streams is derived from the seven largest springs in the basin. The springs are supplied by diffuse contributions from the regional aquifer system...
Mean annual runoff in the upper Ohio River basin, 1941-70, and its historical variation
Robert M. Beall
1978, Water Supply Paper 2042
A map of the Ohio River basin above the Muskingum River shows patterns of mean annual runoff for the new climatologic and hydrologic reference period, 1941-70, and provides an up-to-date, consistent basis for consideration of this streamflow characteristic. The primary data base consisted of 98 long-term gaging-station records collected within...
Improvements in magnetic observatory construction and operation in permafrost areas
John B. Townshend
1978, Open-File Report 78-213
The operation of the Barrow, Alaska, magnetic observatory (lat. 71.32°N, long. 156.62°W) has been complicated because foundations for the instrument piers must be constructed on permafrost. Better understanding of environmental conditions and the availability of more modern instrumentation since the original construction have led to the design and construction of...
Preferred and observed conditions for sockeye salmon in Ozette Lake and its tributaries, Clallam County, Washington
Gilbert C. Bortleson, N. P. Dion
1978, Water-Resources Investigations Report 78-64
Ozette River and Ozette Lake and its tributaries in Washington have many of the water-quality and stream-hydraulic characteristics that are generally supportive of good sockeye salmon production. Ozette Lake is a large, deep lake and a natural rearing area and for young sockeye. In the summer of 1976 water temperatures...
