The determination of low levels of cobalt-60 in environmental waters by liquid scintillation counting
H.C. Claassen
1970, Analytica Chimica Acta (52) 229-235
A method for determination of cobalt-60 in waters at levels greater than 0.5 pCi per sample is presented. A modification of the method may be used to analyze fluvial sediments and soils. After the cobalt has been separated, first as the hydroxide and then as...

Waterfowl breeding habitat in agricultural and nonagricultural land in Manitoba
T.J. Dwyer
1970, Journal of Wildlife Management (34) 130-136
Waterfowl populations and habitat characteristics were examined on 33 potholes in each of two 16-square-mile study areas of agricultural and nonagricultural land in southwestern Manitoba. The agricultural land potholes, lacking in or incompletely surrounded by trees, received greater use by lesser scaup (Aythya affinis), canvasback (A. valisineria), redhead (A. americana),...
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, 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...

Effect of sample inhomogeneity in K Ar dating
J. C. Engels, C.O. Ingamells
1970, Geochimica et Cosmochimica Acta (34) 1007-1017
Error in K-Ar ages is often due more to deficiencies in the splitting process, whereby portions of the sample are taken for potassium and for argon determination, than to imprecision in the analytical methods. The effect of the grain size of a sample and of the composition of a contaminating...

Search for organic compounds in the lunar dust from the Sea of Tranquillity

1970, Science (167) 760-762
A sample of lunar dust was examined for organic compounds. Carbon detected in concentrations of 157 micrograms per gram had a δ13C per mil (PDB) value of + 20. Treatment with hydrochloric acid yielded hydrocarbons of low molecular weight, suggesting the presence of carbides. The gas chromatogram of the acylated...
Taunton River basin
John R. Williams, Richard E. Willey
1970, Massachusetts Hydrologic - Data Report 12
The Taunton River, emptying into an arm of Narragansett Bay at Fall River, drains 528 square miles of interior southeastern Massachusetts. The Taunton River basin is separated from the basins of short streams draining to the coast by low divides on the east, south, and southwest. On the west and...
The diffusion of ions in unconsolidated sediments
F.T. Manheim
1970, Earth and Planetary Science Letters (9) 307-309
Diffusion in unconsolidated sediments generally proceeds at rates ranging from half to one twentieth of those applying to diffusion of ions and molecules in free solution. Diffusion rates are predictable with respect to porosity and path tortuosity in host sediments, and can be conveniently measured by determinations of electrical resistivity...
Lunar Maria and circular basins-a review
D.E. Stuart-Alexander, K. A. Howard
1970, Icarus (12) 440-456
Lunar Orbiter data make it possible to examine the distribution and relations of maria and large circular basins over the entire Moon. The restricted distribution and age of the maria are in marked contrast to the apparently random distribution in time and place of the circular basins, some of which...
Photogeologic and thermal infrared reconnaissance surveys of the Los Negritos-Ixtlan de los Hervores geothermal area, Michoacan, Mexico
Valle R. Gomez, J. D. Friedman, S.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...
UThPb age of Apollo 12 rock 12013
M. Tatsumoto
1970, Earth and Planetary Science Letters (9) 193-200
A UThPb isotopic study of three chips from lunar rock 12013 indicates that parental material of the intrusion breccia formed quite early in the moon's history, possibly 3.9 to 4.3 by ago. The UThPb characteristics of the rock are distinctly different from those of other Apollo 12 igneous rocks and...
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...

Toxicity of 33 NCS to freshwater fish and sea lamprey
Leif L. Marking, Everett L. King, Charles R. Walker, John H. Howell
1970, Investigations in Fish Control 38
The chemical 33NCS (3'-chloro-3-nitrosalicylanilide) was evaluated as a fish control agent and as a larvicide for sea lampreys at the Fish Control Laboratories of the Bureau of Sport Fisheries and Wildlife and the Hammond Bay Biological Station of the Bureau of Commercial Fisheries. The chemical is rapidly toxic to many...

Accumulation of radionuclides in bed sediments of the Columbia River between Hanford reactors and McNary Dam
Jack L. Nelson, W.L. 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...
