Physio-chemical and morphological characteristics of avian encephalomyelitis virus
L.H. Gosting, B.W. Grinnell, M. Matsumoto
1980, Veterinary Microbiology (5) 87-100
Avian encephalomyelitis virus (AEV) was purified from infected chick embryos by a gradient centrifugation in cesium chloride. The virus had a buoyant density of 1.31 to 1.32 g/ml and a sedimentation coefficient of 148 S. The purified AEV was resistant to treatments with chloroform, acid pH or trypsin. The presence...
Observations of wing-feather molt and summer feeding ecology of Steller's Eiders at Nelson Lagoon, Alaska
Margaret R. Petersen
1980, Wildfowl (31) 99-106
The population size, moult chronology, food habits, and feeding behaviour of Steller's Eiders Polysticta stelleri were studied at Nelson Lagoon, Alaska from May to October 1977. Sub-adults were flightless from late July to late August and the adult males were flightless from late August to mid September. Adult females were...

Ground-water resources and geology of Washington and Ozaukee Counties, Wisconsin
H. L. Young, W. G. Batten
1980, Wisconsin Geological & Natural History Survey Information Circular 38
Population growth is placing increased demands on water supplies in Washington and Ozaukee Counties. Water from three principal aquifers supplies most municipal, industrial, irrigation, residential, and farm water needs in these counties. These are the sand-and-gravel, Niagara, and sandstone aquifers. As much as 15 gallons per minute can be obtained...
Modern sedimentary facies of the open Pacific coast and Pleistocene analogs from Montery Bay, California
W.R. Dupre, H.E. Clifton, R. E. Hunter, Michael E. Field
Michael E. Field, et al., editor(s)
1980, Conference Paper, Quaternary depositional environments of the Pacific Coast : Pacific Coast Paleogeography Symposium 4
Depositional processes and sedimentary structures of wave-dominated Pacific coastal environments vary systematically with water depth. The depth-limited open-coast facies identifiable by their sedimentary structures are the inner shelf, barred or nonbarred nearshore, beach, and coastal dune facies. These facies are most commonly preserved in shallowing-upward progradational sequences. The...
Ground-water data for the Salt Basin, Eagle Flat, Red Light Draw, Green River Valley and Presidio Bolson in westernmost Texas
Donald E. White, Joseph S. Gates, James T. Smith, Bonnie J. Fry
1980, Report 259
From October 1971 through October 1974. the U.S. Geological Survey collected ground-water data in the basins in Texas west of the Pecos River drainage area and northwest of the Big Bend country. The basins included are, from east to west: The Presidio Bolson; the Salt Basin; Green River Valley, Eagle...
Development of Ground Water in the Houston District, Texas, 1970-1974
R.K. Gabrysch
1980, Report 241
Total withdrawals of ground water in the Houston district increased 9 percent from about 488 million gallons per day (21.4 cubic meters per second) in 1970 to about 532 million gallons per day (23.3 cubic meters per second) in 1974. The average annual rate of increase from 1960 to 1969...
Mineralogy and diagenesis of low-permeability sandstones of Late Cretaceous age, Piceance Creek Basin, northwestern Colorado
Paula L. Hansley, Ronald C. Johnson
1980, Mountain Geologist (17) 88-106
This report presents preliminary results of a mineralogic and diagenetic study of some low-permeability sandstones from measured surface sections and cores obtained from drill holes in the Piceance Creek Basin of northwestern Colorado. A documentation of the mineralogy and diagenetic history will aid in the exploration for natural gas and...
Summary groundwater resources of Centre County, Pennsylvania
Charles R. Wood
1980, Water Resource Report 48
The northwest third of Centre County lies in the Appalachian Plateaus physiographic province. The higher altitudes are underlain by the Conemaugh, Allegheny, and Pottsville Groups, which consist of sandstone, shale, and thin limestone and coal beds. The average yield of nondomestic wells in the Allegheny Group is 20 gpm (gallons...

Salym: potential W. Siberian oil giant
James W. Clarke, Jack Rachlin
1980, Oil & Gas Journal (78) 132-135
SALYM oil field is on the Lempa high of the Salym uplift in the eastern part of the Khanty-Mansiysk depression in the Middle Ob region of West Siberia. The Salym uplift is about 50 km long and 45 km wide and trends north. The Lempa high is 25 km long and...
Textural and structural evidence for a predeformation hydrothermal origin of the Tungsten Queen Deposit, Hamme District, North Carolina
M. P. Foose, J. F. Slack, T. Casadevall
1980, Economic Geology (75) 515-522
The Hamme tungsten district is composed of a series of steeply dipping quartz-wolframite veins in the Piedmont of North Carolina. Veins are concentrated near the border of the lower Paleozoic Vance County pluton, along its western contact with green-schist-facies metapelites and metavolcanic rocks of the Carolina slate belt. One of...
Pliocene intrusive rocks and mineralization near Rico, Colorado
C. W. Naeser, C. G. Cunningham, R. F. Marvin, J. D. Obradovich
1980, Economic Geology (75) 122-133
Fission-track and potassium-argon studies of intrusive rocks in the vicinity of Rico, Colorado, have shown that there are at least two periods of igneous activity and that significant ore mineralization is associated with alaskites and latites that are 3 to 5 m.y. old. Discordant fission track ages of apatite and...

Seepage study of the West Side and West Canals, Box Elder County, Utah
R.W. Cruff
1980, Technical Publication 67
A study of the gains or losses of the West Side and West Canals from Cutler Reservoir to near Penrose, Box Elder County, Utah, was made to aid in water allocation for the canal system. Four sets of seepage measurements made in 1978 were used in the analysis. Adjustments for...
Chemical quality of water in abandoned zinc mines in northeastern Oklahoma and southeastern Kansas
Stephen J. Playton, Robert E. Davis, Roger G. McClaflin
1980, Circular 82
Onsite measurements of pH, specific conductance, and water temperature show that water in seven mine shafts in northeastern Oklahoma and southeastern Kansas is stratified. With increasing sampling depth, specific conductance and water temperature tend to increase, and pH tends to decrease. Concentrations of dissolved solids and chemical constituents in mine-shaft...

Paleoecological evaluation of Late Eocene biostratigraphic zonations of the Pacific Coast of North America
Kristin McDougall
1980, Paleontological Monograph (2) 1-75
The late Eocene zonal criteria of the west coast of North America are to a large extent controlled by paleoecology and, therefore, the correlation of coeval but environmentally different benthic foraminiferal faunas cannot be achieved before paleoecological control of the biostratigraphy is understood. The faunal trends, morphology, characteristic occurrences and...
