Chemical analyses of thermal and nonthermal springs in Lassen Volcanic National Park and vicinity, California
J. M. Thompson
1983, Open-File Report 83-311
Most thermal waters issuing in Lassen Volcanic National Park (LVNP) are acidic (pH =3.5), low-Cl (concentrations =30 mg/L) hot springs which are characteristic of vapor-dominated hydrothermal systems and, as such, are not useful for liquid chemical geothermometry. Thermal waters at Drakesbad and in Little Hot Springs Valley, hot spring localities...
Isopach and structure contour maps of the Burro Canyon(?) Formation in the Mesa Golondrina and Mesa de los Viejos areas, Chama Basin, New Mexico
Jennie L. Ridgley
1983, Miscellaneous Field Studies Map 1496-A
In the Chama Basin a wequence of conglomerate, sandstone, and red, gray-green, and pale-purple mudstone occurs stratigraphically between the Upper Jurassic Morrison Formation and Upper Cretaceous Dakota Sandstone. This stratigraphic interval has been called the Burro Canyon Formation by several workers (Craig and others, 1959; Smith and others, 1961; Saucier,...
Preliminary stage-discharge relations for Tombigbee River at Gainesville Dam, near Gainesville, Alabama
G. H. Nelson, C. O. Ming
1983, Open-File Report 83-942
The construction of Gainesville Dam and other related channel alterations, completed in 1979, has resulted in changes to the stage-discharge relations in the vicinity. The lack of current-meter measurements, coupled with backwater conditions, makes definition of a single stage-discharge relation impossible. However, limit curves can be defined that would encompass...
Regional geohydrology of the northern Louisiana salt-dome basin, part IV, hydraulic characteristics of the Wilcox-Carrizo aquifer
G.N. Ryals
1983, Water-Resources Investigations Report 83-4132
The Wilcox Group of Paleocene-Eocence age and the Carrizo Sand of Eocene age compose the Wilcox-Carrizo aquifer. Results of 25 aquifer tests and permeability determinations from 43 sidewall cores show that the hydraulic characteristics of the aquifer are variable. Studies of the Carrizo showed that hydraulic conductivity increased as sand-bed...
Habitat Suitability Index Models: Alewife and blueback herring
Garland B. Pardue
1983, FWS/OBS 82/10.58
Alewives and blueback herring are anadromous clupeids found along the Atlantic coast in marine, estuarine, and riverine habitats, depending upon life stage. Both are important commercial species, used fresh or salted for human consumption, and used as crab bait, fish meal (particularly in animal food manufacturing), and fish oil. Alewife...
Habitat Suitability Index Models: Roseate spoonbill
James C. Lewis
1983, FWS/OBS 82/10.50
The roseate spoonbill is a long-legged wading bird with a height of approximately 80 cm (31.5 inches), a wingspan of 1.3 m (4.3 ft), and a weight of 1.6 kg (3.5 Ib }. The bill is narrower near the base (2-3 em, 0.8-1.2 inches) than at the flattened tip (5...
Bryozoan fauna of the Upper Clays Ferry, Kope, and Lower Fairview formations (Edenian, Upper Ordovician) at Moffett Road, northern Kentucky
Olgerts L. Karklins
1983, Open-File Report 83-21
The geology, water movement, and sediment characteristics in the upstream part of the Spring River basin have been appraised, to assist the U.S. EPA in their study of dioxin contamination in the area. The U.S. Environmental Protection Agency has confirmed that the dioxin compound, TCDD (2,3,7 ,8-tetrachlorodibenzo-p-dioxin), is present in...
Ground-water exploration in the South Kohala district, Hawaii County, Hawaii, using vertical electrical sounding
James P. Kauahikaua, Dallas B. Jackson
1983, Open-File Report 83-67
Ten deep electrical resistivity soundings were completed across the island of Hawai?i near the town of Waimea in an effort to locate high-level, dike-impounded water. The resistivity data did not support the existence of a high-level water occurrence. Instead, the data show that a thick basal fresh-water lens underlies the...
Description of slides showing aeromagnetic and gravity data for regional mineral exploration in Colorado, New Mexico, and Arizona
Douglas P. Klein
1983, Open-File Report 83-703
Examples of aeromagnetic and gravity data over 1? x 2? areas are presented for regions near the Cripple Creek mining area, Colorado, and the Lordsburg-Tyrone-Silver City mining areas, southern New Mexico and Arizona. These data indicate broad crustal structures and compositional variations that are marked by magnetization and density contrasts....
Base flow and ground water in upper Sweetwater Valley, Tennessee
R. D. Evaldi, J.G. Lewis
1983, Water-Resources Investigations Report 83-4068
Base flow measurements showed interbasin transfer of water among sub-basins of upper Sweetwater Valley. In general, topographically higher sub-basins have deficient surface outflow unless significant spring flow occurs in the basin. Topographically lower areas adjacent to the main channel of Sweetwater Creek generally have surplus flow. Major flow surpluses were...
