SHUTTLE IMAGING RADAR PROVIDES FRAMEWORK FOR SUBSURFACE GEOLOGIC EXPLORATION IN EGYPT AND SUDAN.
Carol S. Breed, John F. McCauley, Gerald G. Schaber
1984, Conference Paper
Shuttle Imaging Radar provides a pictorial framework to guide exploration for mineral resources (potential placers), groundwater sources, and prehistoric archaeological sites in the Western Desert of Egypt and Sudan. Documented penetration by the SIR-A signal of dry surficial sediment to depths of a meter or more revealed bedrock geologic features...
[Book review] The wildfowl of Britain and Europe
Gary L. Krapu
1984, The Auk (101) 213-214
Of about 140 extant species of waterfowl in the world, 54 occur in the western Pale- arctic. In this, his most recent book, Ogilvie introduces the reader to the waterfowl of Europe including occasional visitors and introduced species. Although written primarily for laymen, ornithologists will find the book informative but...
Climbing in the high volcanoes of central Mexico
R. J. Secor
1984, Earthquake Information Bulletin (USGS) (16) 136-146
A chain of volcanoes extends across central Mexico along the 19th parallel, a line just south of Mexico City. The westernmost of these peaks is Nevado de Colima at 4,636 feet above sea level. A subsidiary summit of Nevado de Colima is Volcan de Colima, locally called Fuego (fire) it...
Blue Mountain Lake, New York, earthquake of October 7, 1983.
G. Wendt
1984, Earthquake Information Bulletin (USGS) (16) 23-23
The October 7 earthquake near Blue Mountain Lake in the central Adirondack Mountains registered a preliminary Richter magnitude of 5.2. It was widely felt throughout the Northeastern United States and Canada and occurred in an area that has been periodically shaken by earthquakes throughout recorded history. Since 1737, at least...
Mineral resources of the Atlantic Exclusive Economic Zone
William P. Dillon
1984, Conference Paper, Oceans Conference Record (IEEE)
Potential mineral resources of the Atlantic Exclusive Economic Zone (including the Gulf of Mexico and US Caribbean areas) include petroleum, sand and gravel, phosphorite, placer deposits of heavy mineral sands, ferromanganese nodules, and fresh water. Although major efforts have been made to search for petroleum, the oil and gas resources...
Comparison of nonlinear least squares and log transformation procedures for calculating volatilization coefficients
R. E. Rathbun, D. Y. Tai
1984, Chemosphere (13) 715-730
A nonlinear least squares procedure and a log transformation procedure for calculating first-order rate coefficients from experimental concentration-versus-time data were compared using laboratory measurements of the volatilization from water of 1,1,1-trichloroethane and 1,2-dichloroethane and the absorption of oxygen by water. Ratios of the nonlinear least squares to log transformation volatilization...
Alaska seismic studies
J. Rogers
1984, Earthquake Information Bulletin (USGS) (16) 28-33
Seismic monitoring in Alaska by the U.S Geological Survey consists of a network of 46 stations focused on the following four areas: Yakatut Bay to Prince William Sound, centered on the Yakatage seismic gap. Anchorage, and the surrounding region of rapid growth and development.  The active Cook Inlet volcanoes-Iliamna,Redoubt and Spurr. (Two of...
Eyewitness account of the 1931 great earthquake at Hawke’s Bay, New Zealand
H. Spall
1984, Earthquake Information Bulletin (USGS) (16) 12-20
No part of New Zealand is far from a known earthquake origin. The magnitude 7.9 earthquake of 1931 at Hawke's Bay, North Island, on February 3, 1931, was the most serious event recorded in New Zealand hsitory. It was responsible for 256 deaths. The Modified Mercalli intensity reached XI in...
Ice and debris in the fretted terrain, Mars
Baerbel K. Lucchitta
1984, Journal of Geophysical Research (89) 409-418
Viking moderate- and high-resolution images along the northern highland margin were studied monoscopically and stereoscopically to contribute to an understanding of the development of fretted terrain. Results support the hypothesis that the fretting process involved flow facilitated by interstitial ice. The process apparently continued for a long period of time,...
The relationship of Landsat digital data to the properties of Arizona rangelands
Emil H. Horvath, D. F. Post, J. B. Kelsey
1984, Soil Science Society of America Journal (48) 1331-1334
Pedon descriptions, vegetation transect information, and Landsat digital data were obtained for 110 sites on the Tonto National Forest in central Arizona. Using the field and satellite data, 33 variables were evaluated and prediction models were generated using stepwise multiple regression techniques. The following six factors explained 84% of the...
Banded iron-formations of late Proterozoic age in the central eastern desert, Egypt: Geology and tectonic setting
P.K. Sims, H. L. James
1984, Economic Geology (79) 1777-1784
In the central Eastern Desert of Egypt, deposits of iron-formation of the Algoma type occur as sharply defined stratigraphic units within layered volcanogenic rocks of late Proterozoic age. The volcanic sequence is characterized by interfingering and repetition of rocks of dominantly andesite-basalt composition and by tectonically juxtaposed ophiolitelike assemblages; it...
Elk and deer diets in old-growth forests in western Washington
David M. Leslie Jr., Edward E. Starkey, Martin Vavra
1984, Journal of Wildlife Management (48) 762-775
Dietary quality and overlap of sympatric Roosevelt elk (Cervus elaphus roosevelti) and Columbian black-tailed deer (Odocoileus hemionus columbianus) were investigated in old-growth forests of the Hoh Valley, Olympic National Park, Washington. Diets of both cervids were comprised mainly of common old-growth flora, particularly in winter. High dietary overlap suggested competitive...
FEDERAL MINERAL LAND INFORMATION SYSTEM.
Richard L. Kleckner
1984, Conference Paper, Technical Papers of the American Congress of Surveying and Mapping
The ability of geographic information systems to combine point, line, and areal data has been widely documented, although the establishment of a particular data base presents its own unique problems. The U. S. Geological Survey is developing a geographic information system consisting of information on Federal surface ownership, Federal subsurface...
Fish cell lines: Characterization by isozyme analysis
B. C. Lidgerding, S.R. Phelps, W. B. Schill
1984, In Vitro (20) 167-171
The electrophoretic mobilities of isozymes from 16 enzyme systems were determined for nine fish cell lines. The relative migration of the malate dehydrogenase and 6-phosphoglucose dehydrogenase isozymes could be used together to distinguish between seven of the fish cell lines. Two cyprinid cell lines could not be distinguished from each...
Predation on lake whitefish eggs by longnose suckers
Robert T. Nester, Thomas P. Poe
1984, Journal of Great Lakes Research (10) 327-328
In November 1981, we observed intense predation on lake whitefish (Coregonus clupeaformis) eggs by longnose suckers (Catostomus catostomus) on lake whitefish spawning grounds in northwestern Lake Huron. Since longnose suckers commonly frequent the same habitat used by spawning lake whitefish, there exists the potential for high losses of eggs due...
