Determination of niobium in the parts per million range in rocks
F. S. Grimaldi
1960, Analytical Chemistry (32) 119-121
A modified niobium thiocyanate spectrophotometric procedure relatively insensitive to titanium interference is presented. Elements such as tungsten, molybdenum, vanadium, and rhenium, which seriously interfere in the spectrophotometric determination of niobium, are separated by simple sodium hydroxide fusion and leach; iron and magnesium are used as carriers for the niobium. Tolerance...

Collection and preservation of fish and other materials exposed to pesticides
Oliver B. Cope
1960, Progressive Fish-Culturist (22) 103-108
The effects of pesticides on fish have become improtant to fish conservation since World War II, when DDT first came into common use. With the development of other potent insecticides and the increasing use of massive dosages in more recent years, the threat to fish and fish foods has increased....

Effect of FeS on the unit cell edge of sphalerite, a revision
Brian J. Skinner, P. B. Barton Jr., G. Kullerud
1959, Economic Geology (54) 1040-1046
Redeterminations of the relation between the composition and unit-cell size of Fe-bearing sphalerites, necessitated because of partial oxidation of the FeS sample used in earlier measurements, are presented. It is noted that the Fe-ZnS solvus curve may also require revision and should be used with caution, particularly for temperature determinations...

The purpose of this paper is to present the results obtained with seven different diets used as starting diets of chinook salmon fry....
Etiology of sockeye salmon 'virus' disease
Raymond W. Guenther, S.W. Watson, R.R. Rucker, A. J. Ross
1959, Special Scientific Report - Fisheries 296
Violent epizootics among hatchery reared sockeye salmon fingerlings (Oncorhynchus nerka) caused by a filterable agent have occurred. In 1954, one source of this infectious, filterable agent was found to be adult sockeye viscera used in the diet for the fingerlings. The results of observations on an epizootic in 1958 indicate...
Mycobacterial infections in adult salmon and steelhead trout returning to the Columbia River Basin and other areas in 1957
1959, Report
The degree of incidence of acid -fast bacillus infections in adult salmonid fishes was determined. The disease was shown to be widely distributed in the area examined. It is believed the primary source of infection is derived from the hatchery practice of feeding infected salmon products to juvenile fish. One...

The papers comprising the various parts of this report contain preliminary results of the U. S. Geological Survey investigations in the U12b.03 and U12b.04 tunnels at the Nevada Test Site, Nye County, Nevada (fig. 1). The geologic studies were undertaken to define the structural, chemical, mineralogic, and some of the...

Thickness, character, and structure of upper Permian evaporites in part of Eddy County, New Mexico
Charles Leslie Jones
1959, Trace Elements Memorandum 1033
Between Project Gnome site and the International Minerals and Chemical Corporation's plant site, in central eastern Eddy County, N. Mex., unconsolidated deposits of Quaternary age and redbeds of Triassic age attain a thickness of about 700 feet, and rest unconformably on evaporites of late Permian age. The upper Permian evaporites...

Gravity and seismic exploration in Yucca Valley, Nevada test site, January-April, 1959
William H. Diment, D.L. Healey, J.C. Roller
1959, Trace Elements Investigations 545
The thickness of the alluvial and tuffaceous deposits that overlie bedrock in Yucca Valley has been inferred from gravity and seismic measurements. Preliminary interpretations indicate that these deposits are thickest in a narrow north-trending trough in the eastern part of the valley. The gravity data delineate a buried north-trending ridge...

Comparison of thickness, grade, and depth of radioactive layers as determined by gamma-ray logging and by core sampling
Carl M. Bunker
1959, Trace Elements Investigations 612
Thickness, grade, and depth data were obtained by analyzing gamma-ray logs and core samples from 56 diamond drill holes penetrating uranium deposits in the Colorado Plateau. The data from the two methods were compared to determine variations found in gamma-ray log interpretation and chemical and radiometric analyses of the drill core. Correlations within each parameter...

Ground-water levels and related hydrologic data from selected observation wells in Nassau County, Long Island, New York
John Isbister
1959, Bulletin GW-41
Nassau County has experienced a rapid growth in population and industry in the past 20 years that has resulted in increased development of its ground-water resources. The county is located in west-central Long Island and its boundaries enclose a land area of 274 square miles. The climate is relatively mild...
Ground-water resources of the Oakland Park area of eastern Broward County, Florida
