Clyde A. Wilson, Robert R. White, Brennon R. Orr, R. Gary Roybal
1981, Technical Report 43
The Rincon and Mesilla Valleys of New Mexico extend from Caballo Reservoir to El Paso del Norte, west of El Paso, Texas. Water supplies for this area are obtained from the Rio Grande and from the saturated sediments filling the intermontane basins of south-central New Mexico.The two major aquifers are...
The possible role of sulfate-reduction kinetics in the formation of hydrothermal uranium deposits
Charles S. Spirakis
1981, Economic Geology (76) 2236-2239
Sulfate is known to be an active oxidizing agent at high temperatures; however, both experimental and geologic evidence indicate that as a hydrothermal solution cools (to about 200 degrees C, depending on pH) kinetic factors slow the rate at which sulfate enters into redox reactions. This retardation of sulfate reduction...

The 508 square miles of the upper Connecticut River basin in north-central Connecticut include the basins of four major tributaries: the Scantic, Park, and Hockanum Rivers, and the Farmington River downstream from Tariffville. Precipitation over this area averaged 44 inches per year during 1931-60. In this period, an additional 3,800...

Substrate conditions and abundance of lake trout eggs in a traditional spawning area in southeastern Lake Michigan
John A. Dorr III, Daniel V. O’Connor, Neal R. Foster, David J. Jude
1981, North American Journal of Fisheries Management (1) 165-172
Spawning by planted lake trout (Salvelinus namaycush) was documented by sampling with a diver-assisted pump in a traditional spawning area in southeastern Lake Michigan near Saugatuck, Michigan in mid-November in 1978 and 1979. Bottom depths at the 11 locations sampled ranged from 3 to 12 m and substrate size from...
Water Resources Research October 1, 1979 - September 30, 1980: Summary statements of research activities by the Water Resources Division
Water Resources Division, U.S. Geological Survey
1981, Report
Research in the WRD had its beginnings in the late 1950's when the "core research" line item was added to the Congressional budget. Since this time the Federal program has grown from a "basic sciences" program to one that includes a broad spectrum of basic and applied scientific investigations. Water...
The EROS Data Center
Water Resources Division, U.S. Geological Survey
1981, Report
The Earth Resources Observation Systems (EROS) Program of the U.S. Department of the Interior, administered by the Geological Survey, was established in 1966 to apply remote-sensing techniques to the inventory, monitoring, and management of natural resources. To meet its primary objective, the EROS Program includes research and training in the...
Synthesis of carbon-14 and deuterium labeled N-nitroso-2 (3',7'-dimethyl-2',6'-octadienyl) aminoethanols
S. L. Abidi, A.L. Idelson
1981, Journal of Labelled compounds and Radiopharmaceuticals (18) 1215-1225
Methods of preparation of carbon-14 and deuterium labeled N-nitroso-2(3,7-dimethyl-2,6-octadienyl) aminoethanols are described. The primary synthetic method involved alkylation of ethanolamine or ethylglycine with suitable chlorides and subsequent mild nitrosation. Isomeric 14C-nitrosamines were also prepared by selective -cleavage of the di-substituted ethanolamine with nitrous acid....

United States Geological Survey Yearbook, fiscal year 1980
Water Resources Division, U.S. Geological Survey
1981, Report
It is not very often that a single event is so overwhelming that it changes public perceptions of natural hazards for generations. Perhaps for the U.S. Geological Survey, the explosive volcanic activity of Mount St. Helens began such a change. After 101 years of careful science of the Earth's past...
Residues of isobornyl thiocyanoacetate (Thanite) and a metabolite in fish and treated ponds
J. L. Allen, J.B. Sills, V. K. Dawson, R.T. Amel
1981, Journal of Agricultural and Food Chemistry (29) 634-636
Isobornyl thiocyanoacetate (Thanite) is an insecticide that induces a surfacing response in fish and therefore has been considered to have potential as a fish collection agent. Analyses for residues of Thanite in carp (Cyprinus carpio) and largemouth bass (Micropterus salmoides) exposed to chemical yielded only a trace of the parent...
Plasma corticosteroid dynamics in channel catfish, Ictalurus punctatus (Rafinesque), during and after oxygen depletion
Davis K. B. Tomasso J.R. K. B., N. C. Parker
1981, Journal of Fish Biology (18) 519-526
Plasma corticosteroid concentrations in channel catfish, Ictalurus punctatus, (normally 1.0 ± 0.3 μg/100 ml) increased significantly (to 5.9 ± 1.2μg/100 ml) in response to acute oxygen depletion and then returned to control levels within 30 min after the dissolved oxygen concentration was increased; however, a secondary increase in plasma corticosteroid...
Studying the Earth from space
Water Resources Division, U.S. Geological Survey
1981, Report
Space age technology contains a key to increased knowledge about the Earth's resources; this key is remote sensing detecting the nature or condition of something without actually touching it. An early and still most useful form of remote sensing is photography which records the scene, as man sees it, on film...
"Duck stamp" dollars reserve native prairie tracts
K.F. Higgins
1981, Rangelands (3) 190-191
Ducks and wetlands are inseparable in the prairies. Hunters know this, bird watchers know this, wildlife managers know this, and most importantly people who manage the croplands and rangelands know this. The 1,746 tracts of native prairie within these upland-wetland complexes known as Waterfowl Production Areas are not the only...
Improved methods for national water assessment, water resources contract: WR15249270
Harold A. Thomas Jr.
1981, Report
The purpose of our research is to develop methods to make National Water Assessment more useful in estimating water availability for economic growth and more helpful in determining the effect of water resource development upon the environmental quality of related land resources. There are serious questions pertaining to the 1975...
Earth fissures and localized differential subsidence
Thomas L. Holzer, Earl H. Pampeyan
1981, Water Resources Research (17) 223-227
Long linear tension cracks associated with declining groundwater levels at four sites in subsiding areas in south-central Arizona, Fremont Valley, California, and Las Vegas Valley, Nevada, occur near points of maximum convex-upward curvature in subsidence profiles oriented perpendicular to the cracks. Profiles are based on repeated precise vertical control surveys...

Organochlorine concentrations in bald eagles: Brain/body lipid relations and hazard evaluation
K.R. Barbehenn, W. L. Reichel
1981, Journal of Toxicology and Environmental Health (8) 325-330
Residue levels of 12 organochlorine compounds found In the brains of bald eagles can be predicted from the corresponding concentrations in the carcass when expressed on a hexane‐extractable lipid basis. The compounds varied by a factor of about 3 in the degree to which they accumulated In the brain. An...
