An assessment of Landsat data acquisition history on identification and area estimation of corn and soybeans
M. M. Hixson, M. E. Bauer, Donna K. Scholz
1982, Remote Sensing of Environment (12) 123-128
In the past decade, numerous studies have demonstrated the potential of satellite remote sensing for providing accurate timely crop area information. This study assessed the impact of Landsat data acquisition history on classification and area estimation accuracy of corn and soybeans in the U.S. Corn Belt. The results illustrate the...
On the tectonics and metallogenesis of West Africa: a model incorporating new geophysical data
David A. Hastings
1982, Geoexploration (20) 295-327
The gold, diamond and manganese deposits of Ghana have attracted commercial interest, but appropriate geophysical data to delineate the tectonic setting of these and other deposits have been lacking until recently. Recent gravity surveys, however, now cover about 75% of the country. When used in a synthesis of the sometimes...
Changes in vegetation and grazing capacity following honey mesquite control
Kirk C. McDaniel, John H. Brock, Robert H. Haas
1982, Journal of Range Management (35) 551-557
Honey mesquite kill and suppression, vegetation response, and changes in grazing use and capacity were evaluated following brush control in north-central Texas. Tree grubbing was most effective for eliminating honey mesquite, but because of soil and plant damage the treatment did not increase grazing capacity or improve range condition compared...

Use of Landsat data to evaluate lesser prairie chicken habitats in western Oklahoma
Richard W. Cannon, Fritz L. Knopf, Lawrence R. Pettinger
1982, Photogrammetric Engineering and Remote Sensing (46) 915-922
Landsat digital data were used to evaluate lesser prairie chicken (Tympanuchus pallidicinctus) habitats in western Oklahoma. Data for 7 (4,144 ha) study areas, 4 in shinnery oak (Quercus havardii), and 3 in sand sagebrush (Artemisia filifolia) rangeland, were analyzed using the Interactive Digital Image Manipulation System at the EROS Center....

1982, Book chapter, Diseases of wildlife in Wyoming, Second edition
Scabies, caused by mites of the genus Psoroptes, is widespread in free-ranging desert bighorn sheet, Rocky Mountain bighorn sheep, elk, and white-tailed deer. It has been identified on captive mule deer and may have been present on bison....
Chemical and mineralogical analysis of devonian black-shale samples from Martin County, Kentucky; Carroll and Washington counties, Ohio; Wise County, Virginia; and Overton County, Tennessee, U.S.A.
J.S. Leventhal, J. W. Hosterman
1982, Chemical Geology (37) 239-264
Core samples of Devonian shales from five localities in the Appalachian basin have been analyzed chemically and mineralogically. The amounts of major elements are similar; however, the minor constituents, organic C, S, phosphate and carbonate show ten-fold variations in amounts. Trace elements Mo, Ni, Cu, V, Co, U, Zn, Hg,...
Ultrasonic borehole televiewer investigation of oceanic crustal layer 2A, Costa Rice Rift
Mark D. Zoback, R.N. Anderson
1982, Nature (295) 375-379
In situ lithostratigraphy and the distribution of fracture and void zones in oceanic layer 2A were examined with an ultrasonic borehole televiewer at IPOD sites 501 and 504B on the south flank of the Costa Rice Rift. These records indicate a decrease in the size of basalt pillows with depth...

Analytical electron microscopy in mineralogy; exsolved phases in pyroxenes
Gordon L. Nord Jr.
1982, Ultramicroscopy (8) 109-119
Analytical scanning transmission electron microscopy has been successfully used to characterize the structure and composition of lamellar exsolution products in pyroxenes. At operating voltages of 100 and 200 keV, microanalytical techniques of x-ray energy analysis, convergent-beam electron diffraction, and lattice imaging have been used to chemically and...

Detection of diethylnitrosamine in nitrate-rich water following treatment with Rhodamine flow tracers
S. L. Abidi
1982, Water Research (16) 199-204
Extremely carcinogenic diethylnitrosamine (DENA) was found to form in up to 75% yield from the reaction of nitrite with the two commonly used water tracing dyes. Rhodamine B and Rhodamine WT, DENA was detected at trace levels (0.13–7.02 μg −1) in river water samples after treatment with the dye and nitrite....
Geothermal systems of the Cascade Range
L.J. Muffler, Charles R. Bacon, W. A. Duffield
1982, Conference Paper, Proceedings of Pacific Geothermal Conference 1982
In the central and southern Cascade Range, plate convergence is oblique, and Quaternary volcanism produces mostly basalt and mafic andesite; large andesite-dacite composite volcanoes and silicic dome fields occur in restricted areas of long-lived igneous activity. To the north, plate convergence is normal, producing widely spaced centers in which mafic...
Atlantic continental margin of the United States

The objective of this Decade of North American Geology (D-NAG) volume will be to focus on the Mesozoic and Cenozoic evolution of the U.S. Atlantic continental margin, including the onshore coastal plain, related onshore Triassic-Jurassic rift grabens, and the offshore basins and platforms. Following multiple compressional tectonic episodes between Africa...

On Nov. 8, 1980, a major earthquake (magnitude 6.5-7.2) occurred 60 km off the coast of N California. A survey of the area using high-resolution seismic-reflection and side-scan sonar equipment revealed the presence of extensive sediment failure and flows in a zone about 1 km wide and 20 km long...
