Annual water-resources review, White Sands Missile Range: 1971
R. R. Cruz
1972, Report
This report presents water-resource information that was collected at White Sands Missile Range during 1971 and early 1972 by personnel of the U.S. Geological Survey, Water Resources Division. Data on ground-water pumpage and resulting water-level fluctuation, chemical quality, percipitation, and surface-water runoff are summarized in the report. The data were...
Distribution and isotopic composition of uranium in lower Nueces River, Nueces Bay and Corpus Christi Bay, Texas
Charles W. Holmes, Elizabeth Ann Slade
1972, Gulf Coast Association of Geological Societies Transactions (22) 315-322
The uranium concentration and isotopic composition of water and suspended sediment from the Nueces River, Nueces Bay and Corpus Christi Bay were determined by alpha-spectroscopy. The average dissolved uranium concentration and radioactivity ratio (U234/U238) of Nueces River water were determined to be 2.44 µg/1 and 1.15 respectively. Water from a...
The EROS Data Center
Water Resources Division, U.S. Geological Survey
1972, Report
The EROS Data Center in Sioux Falls, South Dakota, is operated for the Earth Resources Observation Systems Program of the Department of the Interior by the Topographic Division of the Geological Survey to provide access to Earth Resources Technology Satellite (ERTS) imagery, USGS aerial photography, and NASA aircraft data for...
Acoustic-reflection profiles, eastern Greater Antilles: Leg 3, 1971 cruise, UNITEDGEO I
Louis E. Garrison
1972, Report
IntroductionAs part of a cooperative marine research program designated the Internataional Decade of Ocean Exploration (IDOE), the United states Geological Survey is participating in an investigation of the geologic framework and resource potential of continental margins and small ocean basins in the Gulf of Mexico, Caribbean Sea, and west African...
Acoustic-reflection profiles, Bay of Campeche: International Decade of Ocean Exploration, U.S. Geological Survey, Leg 1, 1971 cruise, UNITEDGEO I
George William Moore
1972, Report
IntroductionAs part of a cooperative marine research program designated the International Decade of Ocean Exploration (IDOE), the United States Geological Survey is participating in an investigation of the geologic framework and resource potential of continental margins and small ocean basins in the Gulf of Mexico, Caribbean Sea, and west African...
Studies on the control of whirling disease (Myxosoma cerebralis)
G.L. Hoffman Sr., G.L. Hoffman Jr.
1972, Journal of Wildlife Diseases (8) 49-53
Based on presumptive evidence of death (extrusion of polar filaments and disintegration of sporoplasm) 1.0%, 0.5%, and 0.25% calcium oxide or potassium hydroxide killed the spores of Myxosoma cerebrallis in vitro. Chlorine at 400 ppm destroyed 36% to 90% of the spores but 13% to 37% of those in the controls...
Fish rhabdoviruses: Morphology and ultrastructure of North American salmonid isolates
R. W. Darlington, R. Trafford, K. Wolf
1972, Archiv Fur Die Gesamte Virusforschung (39) 257-264
The morphology and ultrastructure of three North American salmonid pathogens, Oregon sockeye salmon, chinook salmon and infectious hematopoietic necrosis viruses, were examined by thin sectioning and negative staining after growth in fathead minnow cells at 10 ° C. The viruses matured at the plasma membrane of these cells. They were...
Exposure times necessary for antimycin and rotenone to eliminate certain freshwater fish
P.A. Gilderhus
1972, Journal of the Fisheries Research Board of Canada (29) 199-202
In laboratory flowing-water troughs exposure required to induce 100% mortality, regardless of time to death for antimycin and rotenone against selected freshwater fish species was determined. Carp and white suckers required shorter exposures to antimycin (6 hr) than to rotenone (18–24 hr) at field-use concentrations of 5 and 50 ppb respectively. Bullheads were...
Population biology of alewives, Alosa pseudoharengus, in Lake Michigan, 1949-70
Edward H. Brown Jr.
1972, Journal of the Fisheries Research Board of Canada (29) 477-500
Alewives were unknown in Lake Michigan before 1949, but became extremely abundant in the 1960s and soon exceeded the carrying capacity of the lake. In 1967 they were decimated by a lakewide mass mortality, and have since been less abundant as "adults" (≥120 mm long), although numerous young were produced in...
