Obstacles facing the Venus radar mapper - The implications of gestalt formation in stereo-radargrammetry
R.L. Wildey
1986, Earth, Moon and Planets (36) 41-48
The question of adapting to radar images the existing hardware that form topographic maps through stereo-photogrammetric models, is examined in principle. Such hardware utilizes a human/computer hybrid. Although the problem of brightness differentials between corresponding landmarks can be dealt with pseudo-photoclinometrically, the main problem is whether the perspective in a...

Uranium geochemistry in geopressured-geothermal aquifers of the U.S. Gulf Coast
T. F. Kraemer, Y.K. Kharaka
1986, Geochimica et Cosmochimica Acta (50) 1233-1238
Formation water from U.S. Gulf Coast geopressured-geothermal sandstone aquifers has been analyzed to determine the geochemistry of uranium in these systems. Results of chemical analyses and chemical equilibrium modeling indicate the formation waters are in equilibrium with uraninite (UO2) and coffinite (USiO4). The 234U238U">234U238U activity ratios...

From a national perspective, these were years of great development and change in the use of energy, trouble in the coal industry, and...
Patterns and causes of change in a cliff swallow colony during a 17-year period
Gary L. Krapu
1986, Prairie Naturalist (18) 109-114
The number of cliff swallow (Petrochelidon pyrrhonata) nests at a farmstead in southeastern North Dakota increased at an average annual rate of 87% with house sparrow (Passer domesticus) removal during 1957-60 and 1970-72. Harassment of nesting cliff swallows by house sparrows, adult swallow mortality from cold weather in late May,...

Effects of vegetation manipulation on breeding waterfowl in prairie wetlands--a literature review
H.A. Kantrud
1986, Fish and Wildlife Technical Report 3
Literature on the effects of fire and grazing on the wetlands used by breeding prairie waterfowl is reviewed. Both dabbling and diving ducks and their broods prefer wetlands with openings in the marsh canopy. Decreased use is commonly associated with decreased habitat heterogeneity caused by tall, robust hydrophytes such as...
Techniques for studying nest success of ducks in upland habitats in the prairie pothole region
Albert T. Klett, Harold F. Duebbert, C. A. Faanes, K.F. Higgins
1986, Resource Publication 158
Selected procedures are described for conducting nesting studies of upland nesting ducks in the prairie pothole region. Emphasis is on the use of standard procedures so that comparable results can be obtained. Major topics addressed are finding nests by flushing hens with drags pulled by vehicles, recording of appropriate data,...

Solubility relations in the system potassium chloride-ferrous chloride-water between 25 and 75.degree.C at 1 atm
I.-M. Chou, L.D. Phan
1986, Journal of Chemical and Engineering Data (31) 154-156
Solubility relations in the ternary system KCl-FeCl2-H2O have been determined by means of the visual polythermal method at 1 atm from 18 to 75??C along 10 composition lines. Solubilities of sylvite were measured along five composition lines defined by mixing KCl with five aqueous FeCl2 solutions containing 10, 20, 30,...
Volcano monitoring at the U.S. Geological Survey's Hawaiian Volcano Observatory
1986, Earthquakes & Volcanoes (USGS) (18) 4-69
The island of Hawaii has one of the youngest landscapes on Earth, formed by the frequent addition of new lava to its surface. Because Hawaiian eruptions are generally nonexplosive and easily accessible, the island has long attracted geologists interested in studying the extraordinary power of volcanic eruption. The U.S. Geological...
Guidelines to classification and nomenclature of Arabian felsic plutonic rocks
C.R. Ramsay, D. B. Stoeser, A.R. Drysdall
1986, Journal of African Earth Sciences (4) 13-20
Well-defined procedures for classifying the felsic plutonic rocks of the Arabian Shield on the basis of petrographic, chemical and lithostratigraphic criteria and mineral-resource potential have been adopted and developed in the Saudi Arabian Deputy Ministry for Mineral Resources over the...
Geohydrology of the Lloyd aquifer, Long Island, New York
M. S. Garber
1986, Water-Resources Investigations Report 85-4159
The Lloyd aquifer contains only about 9% of the water stored in Long Island 's groundwater system but is the only source of potable water for several communities near the north and south shores. The Lloyd aquifer is virtually untapped throughout most of central Long Island because current legal restrictions...
Ground-water movement in the upper glacial aquifer in the Manorville area, Town of Brookhaven, Long Island, New York, in November 1983
D. A. Eckhardt, E. J. Wexler
1986, Water-Resources Investigations Report 85-4035
Water levels in 52 wells near the Manorville scavenger-waste disposal facility in the Town of Brookhaven were measured in November 1983 to determine the direction and gradients of groundwater flow in the upper glacial aquifer. Groundwater moves south-southeastward (S22 degrees E) from the groundwater divide, about 6 miles north of...

Feeding ecology of sandhill cranes during spring migration in Nebraska
K. J. Reinecke, Gary L. Krapu
1986, Journal of Wildlife Management (50) 71-79
We studied the food habits of midcontinent sandhill cranes (Grus canadensis) during spring 1978 and 1979 at their primary staging area along the Platte River and compared population food and foraging habitat requirements with availability. Crane diets varied among the 3 principal foraging habitats, but not between sexes, ages, or...
