Correction of bias in belt transect studies of immotile objects
David R. Anderson, R.S. Pospahala
1970, Journal of Wildlife Management (34) 141-146
Unless a correction is made, population estimates derived from a sample of belt transects will be biased if a fraction of, the individuals on the sample transects are not counted. An approach, useful for correcting this bias when sampling immotile populations using transects of a fixed width, is presented....

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...

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...
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...
Atmospheric collection of debris from the Revelstoke and Allende fireballs
M. H. Carr
1970, Geochimica et Cosmochimica Acta (34) 689-700
In two separate events, Revelstoke and Allende, the air through which a fireball had been observed to pass was sampled for meteoritic debris. Particulate matter was collected on fibrous filters, which were mounted on aircraft and flown downwind from the site of 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...

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...

Discharge measurements at gaging stations
Thomas J. Buchanan, William P. Somers
1969, Techniques of Water-Resources Investigations 03-A8
The techniques used in making discharge measurements at gaging stations are described in this report. Most of the report deals with the current-meter method of measuring discharge, because this is the principal method used in gaging streams. The use of portable weirs and flumes, floats, and volumetric tanks in measuring...
