Estimating water‐table altitudes for regional ground‐water flow modeling, U.S. Gulf Coast
T.A. Williams, A. K. Williamson
1989, Groundwater (27) 333-340
Water‐table altitude, a controlling factor for ground‐ water flow, was estimated from detailed topographic data by subtracting the estimated depth‐to‐water. Land‐surface altitude of the Coastal Plain in the south‐central United States varies from 0 to more than 800 feet above sea level. Predevelopment depth‐to‐water in 6,825 wells less than 150 feet deep...
Geochemical evidence for suppression of pelagic marine productivity at the Cretaceous/Tertiary boundary
James Zachos, M.A. Arthur, Walter E. Dean
1989, Nature (337) 61-64
The normal, biologically productive ocean is characterized by a gradient of the 13C/12C ratio from surface to deep waters. Here we present stable isotope data from planktonic and benthic micro-fossils across the Cretaceous/Tertiary boundary in the North pacific, which reveal a rapid and complete breakdown in this biologically mediated gradient. The...
Efficacy of benzocaine as an anesthetic for salmonid fishes
P.A. Gilderhus
1989, North American Journal of Fisheries Management (9) 150-153
Benzocaine was tested in the laboratory to determine the effective concentrations for anesthetizing juvenile chinook salmon Oncorhynchus tshawytscha and rainbow trout O. mykiss (formerly Salmo gairdneri). Tests were conducted at three water temperatures, in waters ranging from very soft to very hard, and with groups of rainbow trout from 5 to 47 cm long and...
Regression models for estimating urban storm-runoff quality and quantity in the United States
N. E. Driver, B.M. Troutman
1989, Journal of Hydrology (109) 221-236
Urban planners and managers need information about the local quantity of precipitation and the quality and quantity of storm runoff if they are to plan adequately for the effects of storm runoff from urban areas. As result of this need, linear regression models were developed for the estimation of storm-runoff...
Dynamics of liquefaction during the 1987 Superstition Hills, California, earthquake
T.L. Holzer, T. L. Youd, Thomas C. Hanks
1989, Science (244) 56-59
Simultaneous measurements of seismically induced pore-water pressure changes and surface and subsurface accelerations at a site undergoing liquefaction caused by the Superstition Hills, California, earthquake (24 November 1987; M = 6.6) reveal that total pore pressures approached lithostatic conditions, but, unexpectedly, after most of the strong motion ceased. Excess pore pressures were...
Snow cover of the Upper Colorado River Basin from satellite passive microwave and visual imagery
E.G. Josberger, E. Beauvillain
1989, Nordic Hydrology (20) 73-84
A comparison of passive microwave images from the Nimbus-7 Scanning Multichannel Microwave Radiometer (SMMR) and visual images from the Defense Meteorological Satellite Program (DMSP) of the Upper Colorado River Basin shows that passive microwave satellite imagery can be used to determine the extent of the snow cover. Eight cloud-free DMSP...
Heat flow and hydrothermal circulation in the Cascade Range, north-central Oregon
S. E. Ingebritsen, D. R. Sherrod, Robert H. Mariner
1989, Science (243) 1458-1462
In north-central Oregon a large area of near-zero near-surface conductive heat flow occurs in young volcanic rocks of the Cascade Range. Recent advective heat flux measurements and a heat-budget analysis suggest that ground-water circulation sweeps sufficient heat out of areas where rocks younger than 6 Ma (million years ago) are...
Assessment of smolt condition for travel time analysis. Annual report 1988
D.W. Rondorf, J.W. Beeman, J.C. Faler, M.E. Free, E.J. Wagner
1989, Report
Estimates of migration rates and travel times of juvenile salmonids within index reaches of the Columbia River basin are collected through the Smolt Monitoring Program for use by the Fish Passage Center. With increased reliance upon travel time estimates in 1988 by the Fish Passage Center, this study was implemented...
Spatial, seasonal and diel distribution of fishes in a California reservoir dominated by native fishes
Bruce C. Vondracek, Donald M. Baltz, Larry R. Brown, Peter B. Moyle
1989, Fisheries Research (7) 31-53
During 21 months of sampling with various techniques, we captured 24 species of fish in Britton Reservoir. Nine species comprised over 96% of the number of fish captured and approximately 88% of the biomass. Five native non-game species accounted for over 77% of the catches.The native non-game fishes have maintained...

Irrigation-induced contamination--How real a problem
Jonathan P. Deason
1989, Journal on Irrigation Drainage Engineering (115)
The U.S. Department of the Interior has embarked on a series of reconnaissance‐level investigations throughout the western states to identify, evaluate, and respond to irrigation‐induced water quality problems. A series of water, sediment, and biological samples are being analyzed for 17 inorganic constituents and a number of pesticides. 19 studies...

Geochemical expression of early diagenesis in middle Eocene-lower Oligocene pelagic sediments in the southern Labrador Sea, Site 647, ODP Leg 105

1989, Proceedings of the Ocean Drilling Program: Scientific Results (105) 111-135
Geochemical analyses of the middle Eocene through lower Oligocene lithologic Unit IIIC (260-518 meters below sea floor [mbsf]) indicate a relatively constant geochemical composition of the detrital fraction throughout this depositional interval at Ocean Drilling Program (ODP) Site 647 in the southern Labrador Sea. The main variability occurs in redox-sensitive...
Changes in redox conditions in deep‐sea sediments of the subarctic North Pacific Ocean: Possible evidence for the presence of North Pacific Deep Water
Walter E. Dean, J. V. Gardner, Eileen Hemphill-Haley
1989, Paleoceanography (4) 639-653
Cores of upper Quaternary and Holocene sediment from the subarctic North Pacific north of about 48°N contain one or more layers of oxidized brown sediment interbedded within predominantly reduced green sediment. The brown layers are enriched in several trace elements, especially Mn, Mo, Ni, and Co, relative to the green...

Accuracy of acoustic velocity metering systems for measurement of low velocity in open channels
Antonius Laenen, R. E. Curtis Jr.
1989, Water-Resources Investigations Report 89-4090
Acoustic velocity meter (AVM) accuracy depends on equipment limitations, the accuracy of acoustic-path length and angle determination, and the stability of the mean velocity to acoustic-path velocity relation. Equipment limitations depend on path length and angle, transducer frequency, timing oscillator frequency, and signal-detection scheme. Typically, the velocity error from this...
Acid rain publications by the U.S. Fish and Wildlife Service, 1979-1989
Rita F. Villella
1989, Biological Report 80(40.28)
Pollution of aquatic and terrestrial ecosystems has been a concern to society since the burning of fossil fuels began in the industrial revolution. In the past decade or so, this concern has been heightened by evidence that chemical transformation in the atmosphere of combustion by-products and subsequent long-range transport can...

Lead poisoning: The invisible disease
Milton Friend
1989, Fish and Wildlife Leaflet 13.2.6
Lead poisoning is an intoxication resulting from absorption of hazardous levels of lead into body tissues. Lead pellets from shot shells, when ingested, are the most common source of lead poisoning in migratory birds. Other far less common sources include lead fishing sinkers, mine wastes, paint pigments, bullets, and other...
