Geoscientists for international development
David A. Hastings
1980, The British Geologist (6) 104-106
Professional societies are usually concerned with the advancement of scientific knowledge, but a relative newcomer to the international scene has a different focus - geoscience development in the Third World. David Hastings, a member of AGID, explains....
Landsat wildland mapping accuracy
William J. Todd, Dale G. Gehring, J. F. Haman
1980, Photogrammetric Engineering and Remote Sensing (46) 509-520
A Landsat-aided classification of ten wildland resource classes was developed for the Shivwits Plateau region of the Lake Mead National Recreation Area. Single stage cluster sampling (without replacement) was used to verify the accuracy of each class....
Atlantic Flyway review: Region V: Laurel, Prince Georges County, MD (390-0765)
Chandler S. Robbins
1980, North American Bird Bander (5) 34-34
Despite a 22% increase in net-hours, the number of new birds banded dropped 26% from 1977. The decrease was noted in each month and was spread among all of the commonest species, including summer residents, winter residents, permanent residents, and transients. The greatest declines were in Scarlet Tanager (84%), Blue...
Metamorphic infrastructure in the northern Ruby Mountains, Nevada
Keith A. Howard
1980, Book chapter, Cordilleran metamorphic core complexes
The metamorphic complex of the northern Ruby Mountains in northeastern Nevada exposes Paleozoic strata that are metamorphosed to sillimanite grade, migmatized, and recumbently folded. Nappes are variously overturned to the east, north, south, and west. The deeper part of this metamorphic infrastructure is a migmatitic zone pervaded by pegmatitic two-mica...
The composition, structure, and stability of guinier-preston zones in lunar and terrestrial orthopyroxene
Gordon L. Nord Jr.
1980, Physics and Chemistry of Minerals (6) 109-128
Lunar and terrestrial orthopyroxenes (Mg,Fe,Ca)2Si2O6 contain varying abundances of coherent, Ca-enriched Guinier-Preston (G.P.) zones. G.P. zones 5-6 unit cells thick have been found in one lunar sample whereas all other examples (lunar and terrestrial) are only one unit-cell-thick. Electron diffraction maxima from the larger lunar G.P. zones indicate that d100=18.52...

Role of physical barriers in the control of sea lamprey (Petromyzon marinus)
J. B. Hunn, W.D. Youngs
1980, Canadian Journal of Fisheries and Aquatic Sciences (37) 2118-2122
Mechanical and electromechanical barriers played a significant role in the initial attempts to control sea lamprey (Petromyzon marinus) populations in the upper Great Lakes. More recently electromechanical weirs have been used to assess the relative abundance of spawning-run sea lampreys in Lake Superior. Development of an integrated control approach to...
Flood risks and the willingness to purchase flood insurance
M.R. Karlinger, E. D. Attanasi
1980, Water Resources Research (16) 617-622
Computer simulation experiments were conducted to determine the effects of alternative sources of uncertainty on the willingness to pay for flood insurance. Two alternative insurance protection schemes were investigated: coinsurance and fixed coverage. The question investigated here is to what extent does the insurance scheme influence how purchasers respond to...
Some constraints on levels of shear stress in the crust from observations and theory
Art McGarr
1980, Journal of Geophysical Research Solid Earth (85) 6231-6238
In situ stress determinations in North America, southern Africa, and Australia indicate that on the average the maximum shear stress increases linearly with depth to at least 5.1 km measured in soft rock, such as shale and sandstone, and to 3.7 km in hard rock, including granite and quartzite. Regression...

Seismic hazard study of the western portion of the Garlock fault [California]
J.C. Stepp, John LaViolette, Gary Christenson
1980, Open-File Report 80-1172
Investigations of the western segment of the Garlock fault were conducted at Castac Lake, Twin Lakes and Oak Creek Canyon. Studies were concentrated on the youngest fault trace as delineated by Clark (1973). Seismic refraction surveys, topographic surveys and geologic mapping provided positive evidence for fault offsets in Quaternary deposits...

Water quality of Tampa Bay, Florida, June 1972 - May 1976
Carole L. Goetz, Carl R. Goodwin
1980, Water-Resources Investigations Report 80-12
A comprehensive assessment of the water quality of Tampa Bay, Florida, was initiated in 1970 to provide background information to evaluate the effects of widening and deepening the ship channel to the port of Tampa. This report provides results of water-quality sampling in the bay from 1972 to 1976, prior...

Maps showing hydrologic conditions in the San Francisco River area, Greenlee County, Arizona, 1978: A reconnaissance study
Larry J. Mann
1980, Open-File Report 80-441
The San Francisco River area includes about 950 square miles in Greenlee County in east-central Arizona. Water-resources development has been slight compared with that in many areas in Arizona. In 1978 about 500 acre-feet of water was diverted for irrigation from the San Francisco and Blue Rivers, and about 550...
