Spectral characteristics of geomagnetic field variations at low and equatorial latitudes
W.H. Campbell
1977, Journal of Atmospheric and Terrestrial Physics (39) 1217-1227
Geomagnetic field spectra from eight standard observations at geomagnetic latitudes below 30?? were studied to determine the field characteristics unique to the equatorial region. Emphasis was placed upon those variations having periods between 5 min and 4 hr for a selection of magnetically quiet, average, and active days in 1965....
The chronic toxicity of 3-chloro-4-methyl benzamine HCl to birds
Edward W. Schafer Jr., Ronald B. Brunton, Donald J. Cunningham, Norman F. Lockyer
1977, Archives of Environmental Contamination and Toxicology (6) 241-248
3-Chloro-4-methyl benzamine HCl (DRC-1339), an avian toxicant, was fed to five species of birds for periods up to 120 days. The 30-day LC50 of uniformly treated feed for starlings was 4.7 ppm and the 90-day LC50 was 1.0 ppm. The 28-day LC50 for coturnix was 18 ppm. The 30-day LC50 for pigeons was...
Hydraulic conductivity and water quality of the shallow aquifer, Palm Beach County, Florida
W. B. Scott
1977, Water-Resources Investigations Report 76-119
Subsurface geophysical logs were correlated with logs of drill cuttings to determine the permeability of selected zones of the shallow aquifer, Palm Beach County, Fla. The hydraulic conductivity of the aquifer is estimated to range from 1 to 130 feet per day, based on lithology and physical properties. The yield...
Survival of two bacterial fish pathogens (Aeromonas salmonicida and the Enteric Redmouth Bacterium) in ozonated, chlorinated, and untreated waters
Gary A. Wedemeyer, Nancy C. Nelson
1977, Journal of the Fisheries Research Board of Canada (34) 429-432
Ozone and chlorine inactivation curves were determined in three water types at 20 °C for the destruction of the fish pathogens Aeromonas salmonicida, the etiologic agent of furunculosis, and the enteric redmouth bacterium (ERM). In phosphate-buffered distilled water, 0.01 mg/ℓ ozone inactivated 103 cells/ml of ERM and A. salmonicida in 1/2 and 10 min, respectively. Chlorine at...
Nationwide residues of mercury, lead, cadmium, arsenic, and selenium in starlings, 1973
Donald H. White, J. R. Bean, J. R. Longcore
1977, Pesticides Monitoring Journal (11) 35-39
Starlings (Sturnus vulgaris) collected in 1973 at 51 sites throughout the continental United States were analyzed for mercury, lead, cadmium, arsenic, and selenium. All samples contained detectable levels of these elements. In general, residues were low: mercury residues ranged from <0.01 to 0.20 ppm: lead, from <0.10 10 3.20 ppm:...
Water resources data for Washington, water year 1976: Vol. 1 - Western Washington
Water Resources Division, U.S. Geological Survey
1977, Water Data Report WA-76-1
Water resources data for the 1976 water year for Washington, consist of records, of stage, discharge, and water quality of streams; stage, contents, and water quality of lakes and reservoirs; and water levels in wells and springs. This report, in two volumes, contains discharge records for 248 gaging stations; stage...
The measurement of adenosine triphosphate in pure algal cultures and natural aquatic samples
W. Thomas Shoaf, Bruce W. Lium
1976, Journal of Research of the U.S. Geological Survey (4) 241-245
Three methods for the extraction of adenosine triphosphate (ATP) neutral dimethyl sulfoxide (DMSO), boiling tris buffer, and butanol-octanol extraction were equally effective on the alga Chlorella vulgwia. Dilution of extracted ATP samples was linear. Filtration of different volumes of samples resulted in proportional values for ATP in the extracts. Measurement...
The heat capacities at low temperatures and entropies at 298.15 K of low albite, analbite, microline, and high sanidine
R. E. Openshaw, Bruce S. Hemingway, Richard A. Robie, David R. Waldbaum, K. M. Krupka
1976, Journal of Research of the U.S. Geological Survey (4) 204
The heat capacities of low albite and analbite, NaAlSi3O8, and of microcline and high sanidine, KAlSi3Og, have been measured from 15 to 375 K using an adiabatic calorimeter. Tables of the thermodynamic functions C°p, (H°T–H°0)/T, (G°T–H°0)/T, and S°T–S°0 are presented for these four feldspars from 0 to 370 K. At...
Developing a state water plan: Ground-water conditions in Utah, spring of 1976
C.T. Sumison, W.N. Jibson, E.L. Bolke, R. W. Mower, L. R. Herbert, R.M. Cordova, V.L. Jensen, M. D. ReMillard, G. W. Sandberg, L.J. Bjorklund
1976, Cooperative Investigations Report 15
This report is the thirteenth in a series of annual reports that describe ground-water conditions in Utah. Reports in this series, prepared cooperatively by the U.S. Geological Survey and the Utah Division of Water Resources, provide data to enable interested parties to keep abreast of changing ground-water conditions.This report, like...
