Hydrogeologic data for the Eagle River-Chugiak area, Alaska
Paula R. Johnson
1979, Water-Resources Investigations Report 79-59
Water for the Eagle River-Chugiak area is provided by private, subdivision and trailer court wells. Data from these wells were stud-ied to determine aquifer materials, yield, well depth and depth to water. The aquifer material is unconsolidated glacial or alluvial gravel and sand and bedrock from the McHugh Complex, the...
Subsurface stratigraphy and geochemistry of late Quaternary evaporites, Searles Lake, California, with a section on radiocarbon ages of stratigraphic units
George I. Smith, Minze Stuiver
1979, Professional Paper 1043
Searles Lake is a dry salt pan, about 100 km 2 in area, that lies on the floor of Searles Valley, in the desert of southeast California. Several salt bodies of late Quaternary age lie beneath the surface, mostly composed of sodium and potassium carbonate, sulfate, chloride, and borate minerals....
Data compilation of periphyton colonized on artificial substrates placed in the Sacramento and Feather rivers, California, 1975
Linda J. Britton, Rodger F. Ferreira
1979, Open-File Report 79-696
Periphyton was collected from artificial substrates placed in the Sacramento and Feather rivers, California, and analyzed to determine the rate of colonization and succession of periphyton types with time. Samples for determination of water-quality characteristics, especially suspended-sediment concentrations, that might have a direct effect on the growth of periphyton were...
Some peat deposits in Penobscot County, Maine
Cornelia Clermont Cameron, Walter A. Anderson
1979, Open-File Report 79-1096
Twenty of the peat deposits in Penobscot County, Maine contain an estimated 29,282,000 short tons air-dried peat. The peat is chiefly sphagnum moss and reed-sedge of high quality according to ASTM standards for agricultural and horticultural use. Analyses show that this same volume has high fuel value, low sulfur and...
Petrology, sedimentology, and diagenesis of hemipelagic limestone and tuffaceous turbidities in the Aksitero Formation, central Luzon, Philippines
Robert E. Garrison, E. Espiritu, L.J. Horan, L.E. Mack
1979, Professional Paper 1112
The Aksitero Formation of central Luzon is an upper Eocene and lower Oligocene sequence of evenly bedded hemipelagic limestone with a few thin interlayers of tuffaceous turbidites. The limestone consists chiefly of planktonic foraminifers and calcareous nannofossils, with up to 30 percent of noncarbonate components, chiefly volcaniclastic debris. The tuff...
Hydrologic records, Verna well-field area, City of Sarasota, Florida, 1962-76: a data report
Horace Sutcliffe, Anthony Buono
1979, Open-File Report 79-1259
A short history of the development and operation of the Verna well field in Florida is presented. Also included are geological , drillers ' and selected geophysical logs of test and production wells; chemical analyses; specific capacity tests; pumpage; physical dimensions of wells; and source for other data available as...
Impact of flow regulation and powerplant effluents on the flow and temperature regimes of the Chattahoochee River— Atlanta to Whitesburg, Georgia
Robert E. Faye, Harvey E. Jobson, Larry F. Land
1979, Professional Paper 1108
A calibrated and verified transient flow-temperature model was used to evaluate the effects of flow regulation and powerplant loadings on the natural temperature regime of the Chattahoochee River in northeast Georgia. Estimates were made of both instantaneous and average natural temperatures in the river during an 8-day period in August...
Outer Continental Shelf oil and gas information program; Pacific index
Mitre
1979, Open-File Report 79-1327
The Outer Continental Shelf Lands Act of 1953, as amended in 1978, (43 U.S.C. 1331 et seq.), grants to the Secretary of the Interior the authority to issue leases for minerals on the U.S. Outer Continental Shelf (OCS). It provides the authority and guidelines which the Secretary utilizes for expeditious...
Progress in remote sensing as it applies to missions of Committee for Coordination of Joint Prospecting for Mineral Resources in Asian Offshore Areas
William A. Fischer
1979, Open-File Report 79-598
The major thrusts of investigations of the use of space data for understanding our Earth continue to focus on the land and near-shore environments. This is expectable; people live on the land, draw most of their resources from the land or near-shore areas, and in these areas environmental degradation or...
