Surface water records of Cook Inlet basin, Alaska, through September 1975
David R. Scully, Larry S. Leveen, Raymond S. George
1978, Open-File Report 78-498
This report summarizes records of streamflow and water temperature collected prior to October 1, 1975, in the Cook Inlet Basin of south-central Alaska. Streamflow records for gaging stations are tabulated as monthly and annual summaries and annual extremes. For those gaging stations at which continuous or daily water temperature records...
A comparison of rock and soil samples for geochemical mapping of two porphyry-metal systems in Colorado
George J. Neuerburg, H. N. Barton, J.R. Watterson, E. P. Welsch
1978, Open-File Report 78-383
Paired rock and soil samples were collected at widely spaced locations in large segments of the porphyry-metal systems of the Montezuma district in central Colorado and of a northwestward extension of the Summitville district into Crater Creek in southern Colorado. The paired samples do not covary closely enough for one...
Geohydrology of the Antlers aquifer, southeastern Oklahoma
D.L. Hart, Robert Ellis Davis
1978, Open-File Report 78-766
The Antlers aquifer, which consists of as much as 900 feet of friable sandstone, silt, clay, and shale, crops out in area of 1,860 square miles and underlies about 4,400 square miles in southeastern Oklahoma. Precipitation ranges from 34 to 50 inches per year across the outcrop area which is...
Analyses and description of geochemical samples, Cranberry Wilderness Study Area, Pocahontas and Webster counties, West Virginia
J. M. Motooka, J.C. Negri, J. D. Sharkey, F. G. Lesure
1978, Open-File Report 78-215
Semiquantitative spectrographic and other analyses on 104 stream sediment and 100 rock and mineral samples are reported here in detail. Location for all samples are in universal Transverse Mercator (UTM) coordinates. Brief descriptions of rock and mineral samples are included. Rocks analyzed include sandstone and shale; two samples of pyrite...
Low-cost computer classification of land cover in the Portland area, Oregon, by signature extension techniques
Leonard Gaydos
1978, Open-File Report 78-186
Computer-aided techniques for interpreting multispectral data acquired by Landsat offer economies in the mapping of land cover. Even so, the actual establishment of the statistical classes, or "signatures," is one of the relatively more costly operations involved. Analysts have therefore been seeking cost-saving signature extension techniques that would accept training...
Maps showing formation temperatures and configurations of the tops of the Minnelusa Formation and the Madison Limestone, Powder River basin, Wyoming, Montana, and adjacent areas
William J. Head, Kevin Thomas Kilty, Richard K. Knottek
1978, Open-File Report 78-905
This report is part of a study to describe the hydrogeologic framework needed to evaluate the water resources of the Paleozoic age aquifers in the Northern Great Plains coal region. Preliminary studies by the U.S. Geological Survey and State agencies in Wyoming, Montana, and South Dakota have indicated that these...
Floods in the Skunk River basin, Iowa
Albert J. Heinitz, Sulo Werner Wiitala
1978, Open-File Report 79-272
Evaluation of flood hazards, and the planning, design, and operation of various facilities on flood plains require information on floods. This report provides information on flood stages and discharges, flood magnitudes and frequency, and flood profiles for the Skunk River and some of its tributaries. It covers the Skunk --...
Chemical and biological quality of Lakes Faith, Hope, and Charity at Maitland, Florida, with emphasis on the effects of storm runoff and bulk precipitation, 1971-1974
Neville G. Gaggiani, A. G. Lamonds
1978, Open-File Report 77-491
Located in a closed basin, near Orlands, Fla., Lake Faith, Hope, and Charity cover a combined area of 132 acres and are surrounded by residential, citrus grove and undeveloped areas. All of these areas affect the water quality of the lakes through storm runoff and transport of windborne material. During...
Profiles showing potentiometric surfaces and changes in effective stress in aquifers in Harris and Galveston counties, Texas, 1977-78
R.K. Gabrysch
1978, Open-File Report 78-299
These profiles were prepared by the U.S. Geological Survey in cooperation with the Harris-Galveston Counties Coastal Subsidence District and the Texas Department of Water Resources to show the changes in the altitudes of the potentiometric surfaces and, consequently, the changes in effective stress on the framework of the aquifers as...
Isotopic and chemical data from carbonate cements in surface rocks over and near four Oklahoma oil fields
Mitchell E. Henry, Terrence J. Donovan
1978, Open-File Report 78-927
Carbonate cements in outcropping sandstones overlying the Doyle, Fox-Graham, Velma, and part of Wheeler oil fields, Oklahoma, were analyzed for their C13/ 12, 018/016, iron, and manganese compositions. The peculiar areal distribution of the values obtained is interpreted to be the direct result of hydrocarbon microseepage....
