Membrane-micelle model for humus in soils and sediments and its relation to humification
Robert L. Wershaw
1994, Water Supply Paper 2410
Humification, the process whereby biomass consisting of dead plant and animal remains is converted into soil organic matter (humus), is one of the basic processes of the carbon cycle. The organic compounds that make up plant and animal tissue are thermodynamically unstable in the oxidizing atmosphere at the surface of...
Regional Aquifer-System Analysis Program of the U.S. Geological Survey, 1978-1992
Ren Jen Sun, Richard H. Johnston
1994, Circular 1099
The major ground-water systems of the United States have been investigated by the U.S. Geological Survey (USGS) through its Regional Aquifer-System Analysis (RASA) Program. During the first 15 years of the program (1978-92), 25 regional aquifer systems, including the most heavily pumped aquifers in the Nation, were intensively studied. As...
United States Geological Survey, programs in Texas
Water Resources Division, U.S. Geological Survey
1994, Fact Sheet 043-95
Meteorologic and physiographic factors in parts of Texas combine to produce some of the most intense rainstorms in the Nation; these rainstorms cause severe, destructive floods somewhere in the State almost every year. A recent example is the catastrophic flooding in the Houston area in October 1994 that resulted in...
Maps showing interpretation, using R-mode factor analysis, of trace-element abundances in heavy-mineral concentrate samples, Delta 1° x 2° quadrangle, Utah
David R. Zimbelman
1994, Miscellaneous Field Studies Map 2081-G
A set of heavy-mineral concentrate data for the Delta 1° x 2° quadrangle, Utah Conterminous U.S. Mineral Assessment Program (CUSMAP) project was compiled from results of analyses of samples collected during the National Uranium Resource Evaluation Program (SURE), as well as results obtained from samples collected more recently by the...
Stream-aquifer interactions in the Straight River area, Becker and Hubbard counties, Minnesota
J. R. Stark, David S. Armstrong, Daniel R. Zwilling
1994, Water-Resources Investigations Report 94-4009
The Straight River, in north-central Minnesota, is a trout stream having cold, clear water. The 75-square-mile Straight River watershed contributes flow to the stream. The watershed is underlain by highly transmissive surficial and confined-drift aquifers. Ground-water discharge from these aquifers sustains flow in the Straight River, and the cold water...
Reconnaissance of ground-water quality at selected wells in the Beaver Creek watershed, Shelby, Fayette, Tipton, and Haywood Counties, west Tennessee, July and August 1992
A. M. Fielder, A. J. Roman-Mas, M. W. Bennett
1994, Open-File Report 93-366
A reconnaissance of water-quality conditions of the water-table aquifer in the Beaver Creek watershed and other rural areas of Shelby, Fayette, Tipton, and Haywood Counties, Tennessee, was conducted during July and August 1992. The reconnaissance was conducted by the U.S. Geological Survey, in cooperation with the Tennessee Department of Agriculture...
Annual replenishment of bed material by sediment transport in the Wind River near Riverton, Wyoming
M.L. Smalley, W. W. Emmett, A.M. Wacker
1994, Water-Resources Investigations Report 94-4007
The U.S. Geological Survey, in cooperation with the Wyoming Department of Transportation, conducted a study during 1985-87 to determine the annual replenishment of sand and gravel along a point bar in the Wind River near Riverton, Wyoming. Hydraulic- geometry relations determined from streamflow measurements; streamflow characteristics determined from 45 years...
Black Hills hydrology study
D.G. Driscoll
1994, Open-File Report 94-344
The Black Hills area of western South Dakota is a valuable resource center. The area has attracted numerous residents and industries because of the availability of mineral, timber, agricultural, recreational, and water resources. The water resources of the area have been stressed locally by increasing population, periodic drought, and...
Overview of environmental and hydrogeologic conditions at McGrath, Alaska
J.M. Dorava
1994, Open-File Report 94-119
The remote village of McGrath along the Kuskokwim River in southwestern Alaska has long cold winters and short summers. The village is located on the flood plain of the Kuskokwim River and obtains drinking water for its 533 residents from the Kuskokwim River. Surface spills and disposal of hazardous materials...
Quality of water in the Red River alluvial aquifer, pool 1, Red River waterway area, Vick, Louisiana
C. W. Smoot, R. C. Seanor, G. F. Huff
1994, Water-Resources Investigations Report 93-4184
Water-quality changes in the Red River alluvial aquifer within the area affected by pool 1 near Vick, Louisiana, were monitored during pre-construction (1974-78) and post-construction (1984-92) of Lock and Dam 1. Changes greater or less than background values have occurred in an area within 2 miles of Lock and Dam...
Use of boreal forested wetlands by Pacific loons (Gavia pacifica Lawrence) and horned grebes (Podiceps auritus L.): Relations with limnological characteristics
P.J. Heglund, J.R. Jones, L.H. Fredrickson, M.S. Kaiser
1994, Book chapter, Developments in Hydrobiology: Aquatic birds in the trophic web of lakes: Proceedings of a symposium held in Sackville, New Brunswick, Canada, in August 1991
Our objective was to determine if the occurrence and abundance of Pacific loons (Gavia pacifica Lawrence) and horned grebes (Podiceps auritus L.) on 123 wetlands of Yukon Flats National Wildlife Refuge in east central Alaska were related to the limnological characteristics of those wetlands. Aquatic bird-wetland...
Revised correlation chart of coal beds, coal zones, and key stratigraphic units in the Pennsylvanian rocks of eastern Kentucky
Charles L. Rice, John K. Hiett
1994, Miscellaneous Field Studies Map 2275
This report revises Miscellaneous Field Studies Map MF-1188 (Rice and Smith, 1980). Major revisions to the original correlation chart include formal naming of key marine units in Kentucky and replacement of informally named marine units incorrectly projected into Kentucky from adjacent states. Also included in the report is the proper...
Breeding patterns and reproductive success of California sea otters
Marianne L. Riedman, James A. Estes, Michelle M. Staedler, Alisa A. Giles, David R. Carlson
1994, Journal of Wildlife Management (58) 391-399
Following commercial exploitation in the eighteenth and nineteenth centuries, sea otter (Enhydra lutris) populations in Alaska, British Columbia, and Washington recovered at 17-20% a year, yet the California population increased at only 5% a year. This slow rate of increase is perplexing, given that unoccupied and apparently favorable habitats occur...
