A proposed ground water quality monitoring network for Idaho
R.L. Whitehead, D. J. Parliman
1979, Open-File Report 79-1477
A ground water quality monitoring network is proposed for Idaho. The network comprises 565 sites, 8 of which will require construction of new wells. Frequencies of sampling at the different sites are assigned at quarterly, semiannual, annual, and 5 years. Selected characteristics of the water will be monitored by both...
The quality of surface water on Sanibel Island, Florida, 1976-77
Benjamin F. McPherson, T.H. O’Donnell
1979, Open-File Report 79-1478
The quality of surface water in parts of the interior of Sanibel Island has been periodically degraded by high concentrations of salt or macronutrients and by low concentrations of dissolved oxygen. In 1976 the chloride concentration of surface water ranged from about 500 milligrams per liter to almost that of...
Streamflow Estimates in Selected Wisconsin Streams
R.P. Novitzki
1979, Open-File Report 79-1282
The Wisconsin Department of natural Resources needs streamflow information in lake basins where lake-rehabilitation programs are implemented but where long-term stream-gaging stations are not justified. The U.S. Geological Survey provided streamflow estimates for 24 streams in Wisconsin. The estimates were made by the use of (1) midmonthly measurements, (2) basin...
The subsurface geology of the Florida-Hatteras shelf, slope, and inner Blake Plateau
Charles K. Paull, William P. Dillon
1979, Open-File Report 79-448
The structure and stratigraphy of the Florida-Hatteras Slope and inner Blake Plateau was studied by means of 4,780 km of single-channel air gun seismic reflection profiles. Control for the seismic stratigraphy is provided by correlating reflecting units and paleontologically dated stratigraphic units identified in offshore wells and dredge hauls. Many...
Decollement in the southern Allegheny Plateau of Pennsylvania
Howard A. Pohn, Terri L. Purdy
1979, Open-File Report 79-1321
Recent field investigations in the Allegheny Plateau north of Williamsport, Pennsylvania have shown the presence of both southward dipping, low-angle thrust faults translated to the north and northward dipping back or antithectic thrusts translated to the south at the leading (north) edge of Barclay syncline. The presence of these thrusts,...
Investigation of the Hosgri fault, offshore southern California, Point Sal to Point Conception
C. M. Payne, O. E. Swanson, B. A. Schell
1979, Open-File Report 79-1199
A high-resolution seismic reflection survey of the inner continental shelf between Point Sal and Point Conception has revealed faults that displace post-Wisconsin strata (less than 17,000-20,000 years). These faults are the Hosgri fault, the Offshore Lompoc fault, and smaller unnamed faults. Faults trending offshore from the adjacent shoreline such as...
A plan for study of flood hydrology of foothill streams in Colorado
Jerald F. McCain, John L. Ebling
1979, Open-File Report 79-1276
A comprehensive plan is presented for researching methods of flood-data analysis and informatin transfer for foothill areas, and for establishing a hydrologic data-collection network in the foothill areas of Colorado. The research will concentrate on three areas: (1) Developing methods to analyze flood peaks in foothill areas by using gaging-station...
Thrust fault zones in the Allegheny Plateau of north-central Pennsylvania
Howard A. Pohn, Terri L. Purdy
1979, Open-File Report 79-1604
Field investigations in the Williamsport Valley identify lineaments found on Landsat III images, have shown the presence of six discrete fault zones that strike subparallel to the trend of the Appalachian folds. These zones range from 0.5 to 1.75 km in width and from at least 10 km to more...
Petroleum source potential of rocks dredged from the continental slope in the eastern Gulf of Alaska
George Plafker, George Edwin Claypool
1979, Open-File Report 79-295
A bedrock dredging program by the R/V Sea Sounder in 1977 and 1978 along the continental slope in the eastern Gulf of Alaska revealed a previously unknown Eocene sedimentary sequence that includes argillaceous rocks with favorable petroleum source rock characteristics. Seven of 36 dredge hauls that sampled outcrop contain argillaceous...
Stormwater-runoff data for a multifamily residential area, Dade County, Florida
Jack Hardee, Robert A. Miller, Harold C. Mattraw Jr.
1979, Open-File Report 79-1295
Rainfall, stormwater discharge, and water-quality data for a multifamily residential area in Dade County, Florida, are summarized in this report. Loads for 19 water-quality constituents were computed for runoff from 16 storms from May 1977 through June 1978. The 14.7 acre basin contains apartment buildings with adjacent parking lots. The...
