Revised Ages for Laminated Sediment and a Holocene-Marker Diatom from the Northern California Continental Slope
E. Hemphill-Haley, J.V. Gardner
1994, Quaternary Research (41) 131-135
Conventional and accelerator mass spectrometry 14C ages indicate that laminated sediment in three cores from the northern California continental slope near 38??N and 39??N were deposited between 42,000 and 25,000 yr B.P. This revises and refines our previous estimates that laminated sediment accumulated during the late Pleistocene to early Holocene...
The geologic framework of southern Lake Michigan
D.S. Foster, D. W. Folger
1994, Journal of Great Lakes Research (20) 44-60
The bathymetry is controlled by the underlying bedrock. Bedrock comprises Silurian dolomite and Devonian limestone and shale. Quaternary sediment, 10 to 40 m thick, overlies bedrock. From Waukegan, Illinois, south to Indiana Harbor, the bottom is floored by till, sand, pebbles, and cobbvles. The lake floor is erosional or nondepositional...
Simulation of ground-water flow and the movement of saline water in the Hueco Bolson aquifer, El Paso, Texas, and adjacent areas
George E. Groschen
1994, Open-File Report 92-171
The Hueco bolson aquifer is being pumped at increasing rates to supply water for El Paso, Texas, and Ciudad Juarez, Mexico. Water-use projections for 1984-2000 indicate that the upward trend in pumping rates probably will continue, which will put an increasing burden on the limited freshwater resources of the aquifer....
The Venus geologic mappers' handbook
Kenneth L. Tanaka, H. J. Moore, G.G. Shaber, M. G. Chapman, E.B. Stofan, D.B. Campbell, P. A. Davis, J. E. Guest, G.E. McGill, P.G. Rogers, R.S. Saunders, J. R. Zimbelman
1994, Open-File Report 94-438
Habitat impacts of offshore drilling, eastern Gulf of Mexico
Eugene A. Shinn, Barbara H. Lidz, Christopher D. Reich
1994, Open-File Report 94-130
In this survey six offshore exploratory drill sites in a variety of environments and water depths were examined using a small research submersible. Sites varied from locations off northwest Florida to as far west as offshore Alabama. Water depths ranged from 21 m (70 ft) to 149 m (489 ft),...
Genetic diversity in Arctic-nesting geese: Implications for management and conservation
Craig R. Ely, Kim T. Scribner
Richard E. McCabe, Kelly G. Wadsworth, editor(s)
1994, Conference Paper, Transactions of the fifty-ninth North American wildlife and natural resources conference
The North Pacific Rim harbors breeding populations of many unique wildlife resources, of which waterfowl are among the most abundant and taxonomically diverse. Arctic nesting geese in particular are wide-spread in distribution (Figure 1), and though only seasons residents, they have evolved many unique adaptations for breeding in northern latitudes....
Tectonic Speleogenesis of Devils Hole, Nevada, and Implications for Hydrogeology and the Development of Long, Continuous Paleoenvironmental Records
A.C. Riggs, W. J. Carr, Peter T. Kolesar, R.J. Hoffman
1994, Quaternary Research (42) 241-254
Devils Hole, in southern Nevada, is a surface collapse into a deep, planar, steeply dipping fault-controlled fissure in Cambrian limestone and dolostone. The collapse intersects the water table about 15 m below land surface and the fissure extends at least 130 m deeper. Below water, most of the fissure is...
Detailed study of irrigation drainage in and near wildlife management areas, west-central Nevada, 1987-90. Part C. Summary of irrigation-drainage effects on water quality, bottom sediment, and biota
Ray J. Hoffman
1994, Water-Resources Investigations Report 92-4024-C
This report presents a summary of the detailed scientific study of Stillwater Wildlife Management Area and other nearby wetlands in west-central Nevada during 1987-90. The work was funded by the National Irrigation Water Quality Program of the U.S. Department of the Interior with the overall objectives of determining (1) the...
Method to identify wells that yield water that will be replaced by Colorado River water in Arizona, California, Nevada, and Utah
Richard P. Wilson, Sandra J. Owen-Joyce
1994, Water-Resources Investigations Report 94-4005
Accounting for the use of Colorado River water is required by the U.S. Supreme Court decree, 1964, Arizona v. California. Water pumped from wells on the flood plain and from certain wells on alluvial slopes outside the flood plain is presumed to be river water and is accounted for as...
