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...

1959, Florida Geological Survey Report of Investigations 20
The Biscayne aquifer is the source of all fresh ground water in the Oakland Park area of eastern Broward County, Florida. This aquifer extends from the land surface to more than 215 feet below mean sea level and is composed chiefly of sandy marine limestone, calcareous sandstone, and beds of...
Annual water-level measurements in observation wells, 1951-1955, and atlas of maps showing changes in water levels for various periods from beginning of record through 1954, New Mexico
Harold O. Reeder
1959, Technical Report 13
This report tabulates the annual measurements of water level in the observation wells in the various irrigated areas, primarily from 1951 through 1955. It summarizes changes in water level by discussion and with an atlas of nearly all the maps of change of water level for the period of record...
White-spot disease of salmon fry
J. J. Mazuranich, W. E. Nielson
1959, Progressive Fish-Culturist (21) 172-176
White-spot disease, sometimes referred to as coagulated-yolk disease, has been associated with excessive mortalities occurring among the fry and early fingerling stages of the fall chinook salmon (Oncorhynchus tshawytacha) at the U.S. Fish-Cultural Stations at Carson, Cook, Underwood, and Willard, Washington. This disease of eggs and fry should not be...
Effects on fish and wildlife of chemical treatments of large areas
J.L. George
1959, Journal of Forestry (57) 250-254
Summary: The history of field investigations of the effects of DDT on wildlife is reviewed briefly, from the initial studies in 1945 through the more recent studies of the effects of the large-scale programs for spruce-budworm control and gypsy-moth eradication. DDT dosages and procedures that are recommended for...
Observations on the fulvous tree duck in Louisiana
B. Meanley, A.G. Meanley
1959, The Wilson Bulletin (71) 33-45
The Fulvous Tree Duck is a locally common breeding bird of the rice fields of southwestern Louisiana. Observations made in 1955, 1956 and 1957, showed that this species was probably most abundant in the vicinity of Mamou, Evangeline Parish, and Roanoke, Jefferson Davis Parish. Tree ducks arrive in the rice...
Notes on Bachman's sparrow in Central Louisiana
B. Meanley
1959, The Auk (76) 232-234
Notes on the ecology of Bachman’s Sparrow (Aimophila aestivalis) were obtained during a study of birds in relation to the direct or artificial seeding of Longleaf Pine (Pinus palustris) and Loblolly Pine (P. taeda) in central Louisiana from 1955 to 1957. Stoddard (in Burleigh, “Georgia Birds,” pp. 667-668, 1958) has...
