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...
Survival and development of lake herring (Coregonus artedii) eggs at various incubation temperatures
Peter J. Colby, L.T. Brooke
C.C. Lindsey, C.S. Woods, editor(s)
1970, Book chapter, Biology of coregonid fishes
Lake herring eggs stripped and fertilized from a local stock were incubated in a constant-flow incubator at constant temperatures ranging from 0 to 12.1° C. Rate of development, percentage survival, percentage of abnormal and normal hatching, and length of fry at hatching were determined. The average incubation time from fertilization...

Sr87/Sr86 ratios of Quaternary lavas of the Cascade Range, northern California
Zell E. Peterman, I. S. E. Carmichael, A. L. Smith
1970, Bulletin of the Geological Society of America (81) 311-317
Quaternary lavas from Mount Lassen, Mount Shasta, and Medicine Lake, which range in composition from olivine basalt to rhyolite, have Sr87/Sr86 values that fall between 0.7030 and 0.7043, corrected to 0.7080 for the Eimcr and Amend (MIT) SrCO3 standard. These values are very close to average (corrected)...

Clay minerals: A guide to their x-ray identification
Dorothy Carroll
1970, Book
This paper is a guide to the X-ray examination of clay minerals; it incorporates background information concerning the principal crystallographic features of clay minerals, and how this is used in the X-ray identification of these minerals, together with laboratory techniques and the application of X-ray diffractometry to the diagnosis of...
Palynology of the Cretaceous-Tertiary boundary in the northern Rocky Mountain and Mississippi Embayment regions
Robert H. Tschudy
Robert M. Kosanke, Aureal T. Cross, editor(s)
1970, Book chapter, Symposium on Palynology of the Late Cretaceous and Early Tertiary
In both the Rocky Mountain and the Mississippi Embayment regions it is often difficult to distinguish Upper Cretaceous from lower Tertiary rocks on the basis of physical characteristics; the transition can be recognized with relative ease, however, on the basis of abrupt qualitative changes in plant microfossils. Many Cretaceous species...
IASH Commission of Snow and Ice meeting: Paris, France, September 3-5, 1969
Mark Frederick Meier
1970, Eos, Transactions, American Geophysical Union (51) 30-30
The IASH Commission of Snow and Ice met jointly with the Working Group on Glaciology of the Special Committee on Antarctic Research (SCAR).Five technical guides have been prepared by the Commission of Snow and Ice for major IHD projects and have been in press at Unesco for more than a...
On the theory of evolution of river nets
A. E. Scheidegger
1970, International Association of Scientific Hydrology - Bulletin (15) 109-114
An investigation is made of the growth of river basins based on the two current models of the structure of such basins: the cyclic model and the random-graph model. Based on the assumption that the networks grow allometrically, the structure of the network that evolves has...

A brief history of commercial fishing in Lake Erie
Vernon C. Applegate, Harry D. Van Meter
1970, Fishery Leaflet 630
Salient features of the development of the industry from about 1815 to 1968, changes in fishing gears and methods, changes in the kinds and abundance of fishes caught, and the attendant effects of disappearing species on the stability of the fishery are described. The history and present status of the...

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...
Effects of gossypol on rainbow trout Salmo gairdneri Richardson
Roger L. Herman
1970, Journal of Fish Biology (2) 293-303
Rainbow trout were fed gossypol acetate or cottonseed meals containing gossypol for 14 months. Toxic effects were indicated by growth depression, reduced hematocrit, hemo-globin, and total plasma protein. Histological changes were noted, particularly in the liver and kidney....
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....
Immunization of fishes: A review
S. F. Snieszko
1970, Journal of Wildlife Diseases (6) 24-30
Immune response in fishes, which are ectothermic animals, depends on temperature. The optimum response is at the optimum temperature for the species. It is, however, slower in coldwater fishes, such as salmonids, and faster in warmwater fishes.Serum of fishes contains proteins very similar, but not identical, with those of mammals....

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...
Salmonid viruses: Double infection of RTG-2 cells with Egtved and infectious pancreatic necrosis viruses
K. Wolf, P. E. Vestergard Jorgensen
1970, Archiv Fur Die Gesamte Virusforschung (29) 337-342
Egtved and infectious pancreatic necrosis (IPN) viruses were applied at high multiplicity alone and in combination to RTG-2 cells in liquid medium. Procedures were used which selectively suppressed one or the other virus, and the yields were determined after 64 hours at 15°C. The viruses showed an increase of 280...
