Preparation of dart tags for use in the field
Joseph R. Higham
1966, Progressive Fish-Culturist (28) 205
Tagging in the field requires an efficient method of preparing the tags for dispensation under a wide range of conditions. The method described here was very efficient in an extensive tagging program on Oahe Reservoir, South Dakota....
Some effects of sublethal concentrations of sodium arsenite on bluegills and the aquatic environment
P.A. Gilderhus
1966, Transactions of the American Fisheries Society (95) 289-296
Bluegills were exposed to sodium arsenite at various concentrations and treatment frequencies in outdoor pools. The effects of the treatments on the fish and invertebrates in the pools were assessed. Applications totaling 4.0 ppm or more of NaAsO2 during the experiment were reflected in reduced survival and growth of the...
The tullibee
Stanford H. Smith
1966, Minnesota Conservation Volunteer (29) 49-50
Early explorers and settlers of the northeastern United States and southern Canada found lakes teeming with fish that had white flesh and were good to eat. The larger of these they called whitefish, differentiating two kinds- the lake whitefish and the round or menominee whitefish. These looked much...
Some alkali and titania analyses of tektites before and after G-1 precision monitoring
D.B. Tatlock
1966, Geochimica et Cosmochimica Acta (30) 123-128
A comparison of 55 older analyses of Australasian tektites with 110 modern precisely monitored analyses suggests that more than half of the older alkali and titania determinations are decidedly inaccurate and misleading. Deviations of the older analyses from the restricted values of the...
Chemical composition of phosphorites of the Phosphoria Formation
R. A. Gulbrandsen
1966, Geochimica et Cosmochimica Acta (30) 769-778
The chemical composition, both major and minor constituents, of 60 samples of phosphorite from the Phosphoria Formation was determined. Major constituents of the average phosphorite are, by weight per cent: SiO2, 11·9; Al2O3, 1·7; Fe2O3,1·1; MgO, 0·3; CaO, 44·0; Na2O, 0·6; K2O, 0·5; total H2O, 2·2; H2O−, 0·6; TiO2, 0·1;...
Mineral exploration and soil analysis using in situ neutron activation
F. E. Senftle, A.F. Hoyte
1966, Nuclear Instruments and Methods (42) 93-103
A feasibility study has been made to operate by remote control an unshielded portable positive-ion accelerator type neutron source to induce activities in the ground or rock by “in situ” neutron irradiation. Selective activation techniques make it possible to detect some thirty or...
Hydrologic and climatologic data collected through 1964, Salt Lake County, Utah
W.V. Iorns, Reed W. Mower, C. A. Horr
1966, Utah Basic-Data Release 11
An investigation of the water resources of Salt Lake County, Utah, was undertaken by the Water Resources Division of the U.S. Geological Survey in July 1963. This investigation is a cooperative project financed equally by the State of Utah and the Federal Government in accordance with an agreement between the...
Hydrologic and climatologic data, 1965, Salt Lake County, Utah
W.V. Iorns, Reed W. Mower, C. A. Horr
1966, Utah Basic-Data Release 12
An investigation of the water resources of Salt Lake County, Utah, was undertaken by the Water Resources Division of the U.S. Geological Survey in July 1963. This investigation is a cooperative project financed equally by the State of Utah and the Federal Government in accordance with an agreement between the...
Leveling
1966, Topographic instructions of the United States geological survey 2E1-2E5
Geodetic leveling by the U.S. Geological Survey provides a framework of accurate elevations for topographic mapping. Elevations are referred to the Sea Level Datum of 1929....
