Ground water in Myrtle Creek - Glendale area, Douglas County, Oregon
F. J. Frank
1979, Water-Resources Investigations Report 79-8
The Myrtle Creek-Glendale area covers about 400 mi2 (1,000 km2 in Douglas County in southwestern Oregon.  Although the geologic formations of the area have low permeabilities and generally yield small amounts of water to wells, ground water is the chief source of water for domestic usse in rural parts of the...
Ecological and physiological/toxicological effects of petroleum on aquatic birds: A summary of research activities FY76 through FY78
Lucille F. Stickel, Michael P. Dieter
1979, FWS/OBS 79/23
Oil and gas development and exploration in marine coastal areas and the Great Lakes will result in unavoidable spills of polluting oil. Although large oil spills may kill thousands of birds and stimulate much public concern, the bulk of oil that reaches aquatic environmentS released in the course of normal operations,...
Red Cedar River basin, Wisconsin: Low-flow characteristics
W.A. Gebert
1979, Water-Resources Investigations Report 79-29
Low-flow characteristics in the Red Cedar River basin, Wis., where surplus water may be diverted, and methods to determine low-flow characteristics at additional sites are presented. The low-flow characteristics were determined by various methods at 71 sites. For the three gaging stations in the basin, frequency analysis was used to...
Winter feeding habits of quail in longleaf-slash pine habitat
Vincent H. Reid, Phil D. Goodrum
1979, Special Scientific Report - Wildlife 220
Crops of bobwhite quail (Colinus virginianus) collected in 11 years (7,147 in winter and 92 in other seasons) in the longleaf-slash pine (Pinus palustris-P. elliottii) forest type were examined for food content. Seeds of woody plants made up 45% or more of the volume of food found in crops in...
Formation and resulfidization of a South Texas roll-type uranium deposit
Martin B. Goldhaber, Richard L. Reynolds, Robert O. Rye
1979, Open-File Report 79-1651
Core samples from a roll type uranium deposit in Live Oak County, south Texas have been studied and results are reported for Se, Mo, FeS2 and organic-carbon distribution, sulfide mineral petrology, and sulfur isotopic composition of iron-disulfide phases. In addition, sulfur isotopic compositions of dissolved sulfate and sulfide from the...
Steady-state dissolved oxygen model of the Willamette River, Oregon
Stuart W. McKenzie, W. G. Hines, D. A. Rickert, F. A. Rinella
1979, Circular 715-J
For nearly half a century the Willamette River in Oregon experienced severe dissolved-oxygen problems related to large loads of organically rich waste waters from industries and municipalities. Since the mid-1950 's dissolved oxygen quality has gradually improved owing to low-flow augmentation, the achievement of basinwide secondary treatment, and the use...
Metals in Devonian kerogenous marine strata at Gibellini and Bisoni properties in southern Fish Creek Range, Eureka County, Nevada
George A. Desborough, F. G. Poole, R. K. Hose, A. S. Radtke
1979, Open-File Report 79-530
A kerogen-rich sequence of siliceous mudstone, siltstone, and chert as much as 60 m thick on ridge 7129 in the southern Fish Creek Range, referred to as Gibellini facies of the Woodruff Formation, has been evaluated on the surface and in drill holes principally for its potential resources of vanadium,...
Origin of marcasite and its implications regarding the genesis of roll-front uranium deposits
Martin B. Goldhaber, Richard L. Reynolds
1979, Open-File Report 79-1696
Study of five roll-type uranium deposits (three in Texas and two in Wyoming) has resulted in the recognition of ore-stage marcasite in each deposit. Ore-stage marcasite is identified by its close association with uranium- and vanadium-bearing phases in the ore zones; by its close association with ferroselite at and near...
Geohydrology and digital-simulation model of the Farrington aquifer in the northern coastal plain of New Jersey
George M. Farlekas
1979, Water-Resources Investigations Report 79-106
A two-dimensional digital-computer flow model was developed to simulate the Farrington aquifer in the northern part of the Coastal Plain of New Jersey. The area of detailed study includes approximately 500 square miles in Middlesex and Monmouth Couties where the aquifer provides a large part of the municipal and industrial...
Mid- and North Atlantic multichannel seismic reflection profiles, 7, 8 A, B, and C, 12 E, F, G, H, I, and J, and 13 A, B, C, D, E, F, G, and H
Water Resources Division, U.S. Geological Survey
1979, Open-File Report 78-685
Available are four multichannel profiles collected by Digicon Geophysical Corporation in 1975 using a 48-channel streamer (3600 m long), and a 27.9 cubic liter airgun array. They were processed in Denver on the Phoenix "I" by William C. Petterson. The processing includes demultiplexing and resampling, geometry and common-depth-point, definition, velocity...
