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...
Major Land Resource Areas (MLRA)
Adapted from U.S. Soil Conservation Service
1970, Report
This is a polygon coverage of the Land Resource Regions and Major Land Resource Areas of the conterminous United States. Land resource regions are geographic areas that are characterized by a particular pattern of soils, climate, water resources and land uses. (USDA, Soil Conservation Service, 1981). Major land...
Remote Sensor Application Studies Progress Report, July L, 1968 to June 30, 1969. Controlled Field Experiments
L. C. Rowan, Terry W. Offield, R. D. Watson, P. J. Cannon, H.J. Grolier, H. A. Pohn, Kenneth Watson
1970, Report
Field Sites have been selected for controlled experiments to analyze physical and chemical parameters affecting the response of electromagnetic radiation to geological materials. Considerations in the selection of the sites are the availability of good exposures of nearly monomineralic rocks, level of geologic understanding, and ease of access. Seven sites,...
Foraminiferal zonation and carbonate facies of Carboniferous (Mississippian and Pennsylvanian) Lisburne group, central and eastern Brooks range, Arctic Alaska
Augustus K. Armstrong, Bernard L. Mamet, J. Thomas Dutro
1970, American Association of Petroleum Geologists Bulletin (54) 687-698
The Lisburne Group carbonate rocks of the central and eastern Brooks Range contain foraminiferal assemblages assigned to zones of late Tournaisian (Osage) to early Moscovian (Atoka) age. Representatives of both Eurasiatic and American cratonic microfaunas permit correlation with the original Carboniferous type sections in western Europe as well as with...
Thermal features at Volcanoes in the cascade range, as observed by aerial infrared surveys
R.M. Moxham
1970, Bulletin Volcanologique (34) 77-106
There have been no substantial changes in the thermal patterns at the summit of Mount Rainier in the period September 1964–September 1966, within the detection limits of the infrared instrumentation. Some differences in radiance are attributed to differences in snow cover. The highest apparent temperature is at a snow-free area...
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...

Correction of bias in belt transect studies of immotile objects
David R. Anderson, R.S. Pospahala
1970, Journal of Wildlife Management (34) 141-146
Unless a correction is made, population estimates derived from a sample of belt transects will be biased if a fraction of, the individuals on the sample transects are not counted. An approach, useful for correcting this bias when sampling immotile populations using transects of a fixed width, is presented....

Testing of selected pharmacological agents for capturing waterfowl [Annual Progress Report]
D.R. Cline
1970, Report
The response of game-farm mallards (Frost strain) to seven pharmacological immobilizing agents was evaluated in Phase I of a planned four-phase study. A limited amount of testing was also done with wild mallards. Single dosages were administered to determine the mean effective dose (ED50) and mean lethal dose (LD50), The...
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....

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...

1970, Journal of Animal Ecology (39) 505-519
Between 1966 and 1967 populations of Uta stansburiana in southern Nevada increased about 40%. Over the next year they declined by about 50%. These changes are explained in terms of annual differences in fecundity and survival. Most females laid five clutches of...
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...
Winds over saltcedar
T. E. A. Van Hylckama
1970, Agricultural Meteorology (7) 217-233
An analysis of hourly wind speeds above and within a stand of saltcedar near Buckeye, Arizona, reveals that in 90% of all observed cases, the wind profiles above the stand can be represented by the simple logarithmic equation: uz=u*k1n">uz=u*k1n (zz0)">zz0) where...

C. E. Hedge, R.A. Hildreth, W.T. Henderson
1970, Earth and Planetary Science Letters (8) 434-438
The87Sr/86Sr ratios have been determined in 22 volcanic rocks from Oregon and Washington. The emphasis of the study was on andesites and dacites, but several basalts were included. Most of the samples have a very limited range in strontium isotopic composition...
Isotopic investigations of xenoliths and host basalts from the Honolulu volcanic series
J. R. O’Neil, C. E. Hedge, E.D. Jackson
1970, Earth and Planetary Science Letters (8) 253-257
Oxygen, carbon and strontium isotope ratios point to a ground-water origin for the carbonates found in Hawaiian Volcanic Series rocks. Strontium isotope ratios in the xenoliths and host basalts indicate a genetic relationship between them....
Effects of oil development in Arctic America
J. C. Reed
1970, Biological Conservation (2) 273-277
Large and important discoveries of petroleum were made in northern Alaska in 1968. The reserves were estimated then to be perhaps as much as ten thousand million barrels. Subsequent exploration has shown the resources to be much greater than was estimated earlier. Many...
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,...
