Accumulation of radionuclides in bed sediments of the Columbia River between Hanford reactors and McNary Dam
Jack L. Nelson, William Leland Haushild
1970, Water Resources Research (6) 130-137
Amounts of radionuclides from the Hanford reactors contained in bed sediments of the Columbia River were estimated by two methods: (1) from data on radionuclide concentration for the bed sediments between the reactors and McNary Dam, and (2) from data on radionuclide discharge for river stations at Pasco, Washington, and...
Stress of anesthesia with M.S. 222 and Benzocaine in Rainbow Trout (Salmo gairdneri)
Gary Wedemeyer
1970, Journal of the Fisheries Research Board of Canada (27) 909-914
Rainbow trout (Salmo gairdneri) anesthetized with M.S. 222 for periods up to 12 min experience interrenal ascorbate depletion, uremia, and moderate hypercholesterolemia. Anesthesia with neutralized M.S. 222 (pH 7) or benzocaine prevented these changes and significantly reduced the variability in plasma glucose, cholesterol, and cortisol, indicating that the stress of anesthesia...
Precipitating antibody against Aeromonas salmonicida in serums of inbred albino Rainbow Trout (Salmo gairdneri)
Douglas P. Anderson, George W. Klontz
1970, Journal of the Fisheries Research Board of Canada 1389-1393
Precipitins in albino rainbow trout serums were demonstrated by gel diffusion after a single parenteral exposure to the soluble antigens of Aeromonas salmonicida. The fraction of the serum containing antibody activity against the presented antigens was shown by immunoelectrophoresis to be in the nonmigrating region. This corresponded to the beta-2 fraction...
Morphology of certain viruses of Salmonid Fishes. I. in vitro studies of some viruses causing Hematopoietic Necrosis
Donald F. Amend, Velma C. Chambers
1970, Journal of the Fisheries Research Board of Canada (27) 1285-1293
An electron microscope study was performed on three virus isolates that caused hematopoietic necrosis in salmonid fishes: infectious hematopoietic necrosis (IHN), Oregon Sockeye Disease (OSD), and Sacramento River Chinook Salmon Disease (SRCD). All three isolates were examined by negative staining of fathead minnow (FHM) monolayer tissue culture concentrates and IHN...
Morphology of certain viruses of Salmonid fishes. II. In vivo studies of infectious Hematopoietic Necrosis Virus
Donald F. Amend, Velma C. Chambers
1970, Journal of the Fisheries Research Board of Canada (27) 1385-1388
Juvenile sockeye salmon (Oncorhynchus nerka) were injected with the infectious hematopoietic necrosis (IHN) virus, and tissue samples from the anterior kidney, spleen, liver, intestine, and pyloric caeca of moribund fish were prepared for electron microscopy. Bullet-shaped virus particles measuring 158 × 90 mμ were observed in the hematopoietic tissues of the anterior kidney...
Control of infectious Hematopoietic Necrosis virus disease by elevating the water temperature
Donald F. Amend
1970, Journal of the Fisheries Research Board of Canada (27) 265-270
Studies were performed to determine if increasing water temperatures could control infectious hematopoietic necrosis virus (IHN) disease in sockeye salmon (Oncorhynchus nerka). Mortalities could be prevented if the water temperature was raised to at least 18 C within the first 24 hr after infection of the fish and if the fish were...
Experimental control of Columnaris sisease with a new Nitrofuran drug, P-7138
Donald F. Amend, Avron J. Ross
1970, Progressive Fish-Culturist (32) 19-25
P-7138 is a new, broad-spectrum, vinylogous, nitrofuran chemotherapeutic that was developed specifically for treating fish diseases. Although it can be added to the diet of fish, therapeutic tissue levels can be obtained in eels (Anguilla japonica) and goldfish (Carassius auratur) by absorption of the drug directly from the water. Moreover,...
Retention of mercury by salmon
Donald F. Amend
1970, Progressive Fish-Culturist (32) 192-194
Consuming fish that have been exposed repeatedly to mercury derivatives is a potential public health hazard because fish can accumulate and retain mercury in their tissues (Rucker, 1968). Concern has been expressed in the United States because mercurials have been used extensively in industry and as prophylactic and...

Photogeologic and thermal infrared reconnaissance surveys of the Los Negritos-Ixtlan de los Hervores geothermal area, Michoacan, Mexico
Valle R. Gomez, J. D. Friedman, Stephen J. Gawarecki, C.J. Banwell
1970, Geothermics (2)
New techniques, involving interpretation of panchromatic, ektachrome and ektachrome infrared aerographic photogaphs and thermographic infrared imagery recording emission from the earth's surface in middle and far infrared wavelengths (3–5μm and 8–14μm), are being introduced in geothermal investigations in Mexico to identify outstanding structural and geologic features in a rapid and...
UV identification and quantitative measurement of quinaldine residues in fish
J. S. Allen, J.B. Sills
1970, Journal of the Association of Official Analytical Chemists (53) 1170-1171
A method for the confirmatory analysis of quinaldine residue in fish is described. The method utilizes the same extraction and cleanup procedure as the GLC method reported previously. The lower limit of sensitivity for quinaldine residue in fish muscle is 0.01 ppm. Identification is accomplished by comparing the UV spectra...
Middle Miocene hiatus in volcanic activity in the Great Basin area of the Western United States

A summary of potassium-argon dates shows that a high level of igneous activity in the Great Basin and adjacent regions during middle Tertiary time (40 to 20 my ago) was followed by a...
Use of microearthquakes in the study of the mechanics of earthquake generation along the San Andreas fault in central California
J. P. Eaton, W.H.K. Lee (compiler), L. C. Pakiser
1970, Tectonophysics (9) 259-282
A small, dense network of independently recording portable seismograph stations was used to delineate the slip surface associated with the 1966 Parkfield-Cholame earthquake by precise three dimensional mapping of the hypocenters of its aftershocks. The aftershocks were concentrated in a very narrow vertical zone beneath or immediately adjacent to the...
Determination of niobium in rocks by an isotope dilution spectrophotometric method
L. Paul Greenland, E.Y. Campbell
1970, Analytica Chimica Acta (49) 109-114
Rocks and minerals are fused with sodium peroxide in the presence of carrierfree 95Nb. The fusion cake is leached with water and the precipitate dissolved in hydrofluoric-sulfuric acid mixture. Niobium is extracted into methyl isobutyl ketone and further purified by ion exchange. The amount of niobium...
Strontium isotopes in Quaternary basalts of southeastern California
Z. E. Peterman, I. S. E. Carmichael, A. Peyton Smith
1970, Earth and Planetary Science Letters (7) 381-384
Strontium isotopic variations (87Sr/86Sr of 0.7029 to 0.7052) in Quaternary basalts of southeastern California, USA, are not readily explained by assimilation of crustal material similar to that contained as xenoliths in the basalt. Isotopic differences between chrome diopside (0.7016) and olivine...
Isotopic investigations of xenoliths and host basalts from the Honolulu volcanic series
J. R. O'Neil, Carl E. Hedge, E.D. Jackson
1970, Earth and Planetary Science Letters (8) 253-257
Oxygen, carbon and strontium isotope ratios point to a ground-water origin for the carbonates found in Hawaiian Volcanic Series rocks. Strontium isotope ratios in the xenoliths and host basalts indicate a genetic relationship between them....

John Wesley Powell: soldier, explorer, scientist
Water Resources Division U.S. Geological Survey
1970, Report
One hundred years ago John Wesley Powell and nine adventure-seeking companions completed the first exploration of the dangerous and almost uncharted canyons of the Green and Colorado Rivers. By this trip, Powell, a 35-year old teacher of natural history, apparently unhampered by the lack of his right forearm (amputated after...
Surface coating effects in remote sensing measurements
Robert D. Watson
1970, Journal of Geophysical Research (75) 480-484
Measurements of the infrared spectra of a liquid-(water) coated quartz substrate and a solid-(pyrophyllite) coated quartzite are compared to theoretical values. Results demonstrate that in the case of the water-coated quartz, a loss in spectral contrast of the quartz emission occurs at the principal restrahlen wavelengths of 8.5, 9.0, and...
