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...
Lithium metaborate flux in silicate analysis
C.O. Ingamells
1970, Analytica Chimica Acta (52) 323-334
Lithium metaborate is an effective flux for silicates and other rock-forming minerals. The glass resulting from fusion is mechanically strong, reasonably nonhygroscopic, and is readily soluble in dilute acids. These characteristics lead to its use in X-ray spectrography and in methods which require whole-rock solutions,...
UV identification and quantitative measurement of quinaldine residues in fish
J. L. Allen, J.B. Sills
1970, Journal of the Association of Official Analytical Chemists (53) 1170-1171
A method for the confirmatory analysis of quinaldine residue in fish is described. The method utilizes the same extraction and cleanup procedure as the GLC method reported previously. The lower limit of sensitivity for quinaldine residue in fish muscle is 0.01 ppm. Identification is accomplished by comparing the UV spectra...

Toxicity of 33NCS (3'-chloro-3-nitrosalicylanilide) to freshwater fish and sea lampreys
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...

Caldera collapse in the Galápagos Islands, 1968
T. Simkin, K. A. Howard
1970, Science (169) 429-437
The summit caldera of Isla Fernandina, a large, uninhabited basaltic shield volcano, was further enlarged by 1 to 2 km3 in June 1968. A small quake and large vapor cloud on 11 June were followed 4 hours later by a remarkable volcanic ash cloud and, after another hour, by a...
Chemotherapy of fish diseases: A review
R. L. Herman
1970, Journal of Wildlife Diseases (6) 31-34
Fish suffer from environmental, nutritional, viral, bacterial, parasitic, and neoplastic diseases, many of which are similar to those of higher animals. The prevention and treatment of these diseases follow the same principles as diseases of other animals. Fish culture is similar to poultry husbandry in that large numbers of animals...
A new technique for pumping hydrogen gas
I. Friedman, K. Hardcastle
1970, Geochimica et Cosmochimica Acta (34) 125-126
A system for pumping hydrogen gas without isotopic fractionation has been developed. The pump contains uranium metal, which when heated to about 80°C reacts with hydrogen to form UH3. The UH3 is heated to above 500°C to decompose the hydride and regenerate the hydrogen....

Aerial infrared surveys of Reykjanes and Torfajökull thermal areas, Iceland, with a section on cost of exploration surveys
G. Pálmason, J. D. Friedman, R. S. Williams Jr., J. Jonsson, K. Saemundsson
1970, Geothermics (2) 399-412
In 1966 and 1968 aerial infrared surveys were conducted over 10 of 13 high-temperature thermal areas in Iceland. The surveys were made with an airborne scanner system, utilizing radiation in the 4.5–5.5 μm wavelength band.Supplementary ground geological studies were made in the Reykjanes and Torfajökull thermal areas to interpret features...
Fin degeneration of young-of-the-year Alosa pseudoharengus (Clupeidae) in southern Lake Michigan
Edward H. Brown Jr., Carroll R. Norden
1970, Copeia (1970) 766-769
Young-of-the-year alewives, Alosa pseudoharengus, with extremely shortened caudal fins were observed at four locations in southern Lake Michigan between 1964 and 1968. Some of the fins appeared stunted or underdeveloped, but microscopic examination revealed a deterioration of the fins and not an ontogenetic abnormality. Deterioration of the caudal fin was...

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),...
The effect of temperature on the rate of development and survival of alewife eggs and larvae
Thomas A. Edsall
1970, Transactions of the American Fisheries Society (99) 376-380
Eggs from Lake Michigan alewives (Alosa pseudoharengus) were incubated at 79 different temperatures from 42.1 to 87.0 F. Hatching occurred at 44.4-84.9 F and was optimum (38% hatched) at about 64 F. Incubation time varied from 15 days at 45 F to 3.7 days at 70 F and 2.1 days...
New homes for prairie ducks
Harold A. Doty
1970, Report
This pamphlet describes how to make, install and care for inexpensive duck nesting baskets. Ducks have been attracted to these structures in the prairies of eastern North and South Dakota, western Minnesota, and northern Iowa. Nesting structures can help increase the number of local nesting ducks, especially mallards....
