History of salmon in the Great Lakes, 1850-1970
John W. Parsons
1973, Technical Paper 68
This history of the salmon in the Great Lakes describes the decline and extinction of the Atlantic salmon (Salmo salar) in Lake Ontario in the 1800's; the failure to establish, by salmon culture, permanent or sizable populations of Atlantic or Pacific salmon in any of the Great Lakes in 1867-1965;...
An empirical NaKCa geothermometer for natural waters
R.O. Fournier, A.H. Truesdell
1973, Geochimica et Cosmochimica Acta (37) 1255-1275
An empirical method of estimating the last temperature of water-rock interaction has been devised. It is based upon molar Na, K and Ca concentrations in natural waters from temperature environments ranging from 4 to 340°C. The data for most geothermal waters cluster near a straight line when plotted as the...
87Sr/86Sr ratios in basalts from islands in the Indian Ocean
C. E. Hedge, N.D. Watkins, R.A. Hildreth, W. P. Doering
1973, Earth and Planetary Science Letters (21) 29-34
87Sr/86Sr ratios of basalts from islands in the Indian Ocean (0.7040) are higher than those of basalts dredged from the Mid-Indian Ocean Ridge (0.7034). The sources of the island basalts have apparently not been in equilibrium with the source of the...
Fish viruses: Buffers and methods for plaquing eight agents under normal atmosphere
K. Wolf, M. C. Quimby
1973, Applied Microbiology (25) 659-664
A universal procedure was sought for plaque assay of eight fish viruses (bluegill myxovirus, channel catfish virus, eel virus, Egtved virus, infectious hematopoietic necrosis virus, infectious pancreatic necrosis virus, lymphocystis virus, and the agent of spring viremia of carp (Rhabdovirus carpio), in dish cultures of various fish cells. Eagle minimal...
Endrin uptake and release by fingerling channel catfish (Ictalurus punctatus)
R.L. Argyle, G.C. Williams, H.K. Dupree
1973, Journal of the Fisheries Research Board of Canada (30) 1743-1744
Fingerling channel catfish (Ictalurus punctatus) offered diets containing 0.04–4.0 μg endrin/g food (dry weight) rapidly accumulated the pesticide. Amounts in the tissues were directly proportional to amounts in the food. Dietary endrin had no measurable effect on growth or mortality. After endrin was withdrawn from the diet, it rapidly disappeared and...
Application of theory and research in fishery management of the Laurentian Great Lakes
Stanford H. Smith
1973, Transactions of the American Fisheries Society (102) 156-163
The Great Lakes have a high potential for the conduct of research and useful application of research findings, but the history of the Great Lakes indicates that extensive research and intensive management have failed to prevent deterioration of the fisheries. At times the research was not done before a loss...
The selenium content of U.S.G.S. standard rocks
M. M. Schnepfe, F.J. Flanagan
1973, Chemical Geology (12) 77-80
Selenium was determined in duplicate portions from three bottles of six U.S.G.S. standard rocks by a spect rofluorimetric procedure. The following averages, as p.p.m. Se, were obtained: PCC-1, 0.031; GSP-1, 0.088; BCR-1, 0.12; SCo-1, 0.91; MAG-1, 1.3; and SGR-1, 3.7. One-way analysis...
Point of zero charge of weathered forsterite
R.W. Luce, George A. Parks
1973, Chemical Geology (12) 147-153
The point of zero charge of forsterite shifts from an estimated 8.9 for the unaltered mineral to 8.4 and 8.0, respectively, after being weathered artificially for 1 h and 4 h. These results corroborate the presence of magnesium-deficient surfaces on the weathered...
Ferdinand Vandiveer Hayden and the founding of the Yellowstone National Park
Water Resources Division, U.S. Geological Survey
1973, Report
Following the Civil War, the United States intensified the exploration of her western frontiers to gain a measure of the vast lands and natural resources in the region now occupied by our Rocky Mountain States. As part of this effort, the U.S. Geological and Geographical Survey of the Territories was...
An incident of fenthion mosquito control and subsequent avian mortality
R.W. Seabloom, G.L. Pearson, L.W. Oring, J.R. Reilly
1973, Journal of Wildlife Diseases (9) 18-20
Mass mortality among migratory birds at Grand Forks, North Dakota, was attributed to a mosquito control operation employing the insecticide fenthion. The factors involved may have included the toxicity of the pesticide for birds, the method of application and coincidence with the peak of the spring warbler migration....
Floods in New York, 1971
F. Luman Robison
1973, Report
This report, for the calendar year 1971, was prepared at the request of the New York State Department of Transportation under provisions of an agreement between the New York State Department of Environmental Conservation and the U.S. Geological Survey fore a cooperative statewide program investigate the water resources of the...
A method to determine waterfowl shooting distances
D.A. Davenport, G.A. Sherwood, H. W. Murdy
1973, Wildlife Society Bulletin (1) 101-105
Long-range shooting at ducks and geese frequently results in a high crippling loss, unretrieved birds and frustrated hunters. A principal problem has been the general inability of hunters or observers to properly judge distance of birds. This paper describes a reasonably accurate method developed to determine shooting distances to geese....
More on noble gases in Yellowstone National Park hot waters
E. Mazor, R.O. Fournier
1973, Geochimica et Cosmochimica Acta (37) 515-525
Water and gas samples from research wells in hydrothermal areas of Yellowstone National Park, U.S.A., have been mass spectrometrically analyzed for their rare gas contents and isotopic composition. In agreement with previous findings, the rare gases have been found to originate from infiltrating...
The sorption of silver by poorly crystallized manganese oxides
B.J. Anderson, E. A. Jenne, T. T. Chao
1973, Geochimica et Cosmochimica Acta (37) 611-622
The sorption of silver by poorly crystallized manganese oxides was studied using synthesized samples of three members of the manganous manganite (birnessite) group, of different chemical composition and crystallinity, and a poorly organized γ-MnO2. All four oxides sorbed significant quantities of silver. The manganous manganites showed the greatest sorption (up...
Inorganic chemical investigation by x-ray fluorescence analysis: The Viking Mars Lander
P. Toulmin III, A. K. Baird, B. C. Clark, Klaus Keil, H. J. Rose Jr.
1973, Icarus (20) 153-178
The inorganic chemical investigation added in August 1972 to the Viking Lander scientific package will utilize an energy-dispersive X-ray fluorescence spectrometer in which four sealed, gas-filled proportional counters will detect X-rays emitted from samples of the Martian surface materials irradiated by X-rays from radioisotope sources (55Fe and 109Cd). The output...
Radial particle-size segregation during packing of particulates into cylindrical containers
C.D. Ripple, R.V. James, J. Rubin
1973, Powder Technology (8) 165-175
In a series of experiments, soil materials were placed in long cylindrical containers, using various packing procedures. Soil columns produced by deposition and simultaneous vibratory compaction were dense and axially uniform, but showed significant radial segregation of particle sizes. Similar results were obtained with deposition and simultaneous impact-type compaction when...
