Subsidence and volcanism of the Haleakala Ridge, Hawaii
James G. Moore, D. A. Clague, K.R. Ludwig, R. K. Mark
1990, Journal of Volcanology and Geothermal Research (42) 273-284
Side-looking sonar (GLORIA) mapping has revealed a series of four arcuate bands of high sonic backscatter on the crest of the Haleakala Ridge, a major rift-zone ridge extending 135 km east of the island of Maui. Dredge recovery indicates that the shallowest of these bands is a drowned coral reef,...
Palaeobotanical evidence for a marked temperature increase following the Cretaceous/Tertiary boundary
J. A. Wolfe
1990, Nature (343) 153-156
Correspondence analysis of dicot leaf physiognomy of modern vegetational samples from a wide range of environments indicates that >70% of physiognomic variation corresponds to water or temperature factors, or both. Despite wide variation in single physiognomic characters, overall trends can be used to distinguish between samples from different climates. Some...

Consolidation, triaxial shear-strength, and index-property characteristics of organic-rich sediment from the Peru continental margin: Results from Leg 112
Homa J. Lee, Robert E. Kayen, William McArthur
1990, Proceedings of the Ocean Drilling Program: Scientific Results 112-43
Sites 679, 680, and 681 of the Ocean Drilling Program were drilled along an east-west transect across an organic-rich, diatomaceous, coastal upwelling facies that occurs as a shelf/slope lens along the Peru continental margin. Seven 60-cm-long, unsplit core sections from these sites were tested for consolidation, triaxial shear strength, and...

Pattern of solute movement from snow into an upper Michigan stream
R. Stottlemyer, D. Toczydlowski
1990, Canadian Journal of Fisheries and Aquatic Sciences (47) 290-300
Precipitation, snowpack, snowmelt, and streamwater samples were collected in a small gauged watershed draining into Lake Superior during winter 1987–88 to assess the importance of snowmelt pattern and meltwater pathways in the occurrence of solute pulses in streamwater. The snowpack along the south shore of Lake Superior can contain 50%...
Kidney lesions associated with mortality in chickens inoculated with waterfowl influenza viruses
R.D. Slemons, L. N. Locke, Martha G. Sheerar, R. M. Duncan, Virginia S. Hinshaw, B.C. Easterday
1990, Avian Diseases (34) 120-128
Seventy-six type A influenza viruses recovered from waterfowl in Wisconsin, California, South Dakota, Florida, Texas, Alabama, and Nebraska were tested for virulence in chickens. The challenge to chickens was intravenous inoculation of first-, second-, or third-egg-passage virus. Each of the virus strains was tested separately in three or four chickens....
Land-surface subsidence resulting from ground-water withdrawals in the Houston-Galveston region, Texas, through 1987
R.K. Gabrysch, L.S. Coplin
1990, Report
The ground-water system in the Houston-Galveston region, Texas is composed of layers of sand and compressible clay. The system has been divided into two major aquifers, the Chicot and Evangeline, and the underlying Burkeville confining unit. The Chicot aquifer overlies the Evangeline aquifer. The Chicot aquifer contains the most permeable sand layers and...
Bioaccumulation of selenium in birds at Kesterson Reservoir, California
Harry M. Ohlendorf, Roger L. Hothem, Christine M. Bunck, Katherine C. Marois
1990, Archives of Environmental Contamination and Toxicology (19) 495-507
This study was conducted to determine selenium (Se) concentrations in tissues of birds collected during the 1983-1985 nesting seasons at Kesterson Reservoir (an area receiving high-Se irrigation drainage water), compare them with birds from reference sites within California's Central Valley, and relate them to food-chain Se concentrations at the study...
Acid precipitation and food quality: Inhibition of growth and survival in black ducks and mallards by dietary aluminum, calcium and phosphorus
Donald W. Sparling
1990, Archives of Environmental Contamination and Toxicology (19) 457-463
In areas impacted by acid precipitation, water chemistry of acidic ponds and streams often changes, resulting in increased mobilization of aluminum and decreased concentration of calcium carbonate. Aluminum binds with phosphorus and inhibits its uptake by organisms. Thus, invertebrate food organisms used by waterfowl may have inadequate Ca and P...

Age and depositional setting of siliceous sediments in the upper Paleozoic Havallah sequence near Battle Mountain, Nevada; Implications for the paleogeography and structural evolution of the western margin of North America
Benita L. Murchey
David S. Harwood, M. Meghan Miller, editor(s)
1990, Book chapter, Paleozoic and early Mesozoic paleogeographic relations; Sierra Nevada, Klamath Mountains, and related terranes
The upper Paleozoic Havallah sequence of central Nevada is a folded and thrust-faulted association of greenstone, siliceous marine sedimentary rocks, and deep-water clastic rocks. Microfossil assemblages (radiolarians, sponge spicules, and conodonts) are used as tools to unravel the stratigraphy and to interpret the paleoenvironments of the siliceous sedimentary rocks. Nine...
Monitoring long-term effects of offshore oil and gas development along the Southern California outer continental shelf and slope: Background environmental conditions in the Santa Maria Basin

1990, Oil and Chemical Pollution (6) 195-240
Potential environmental impacts of materials discharged from oil and gas development and production platforms off the coast of southern California (Santa Maria Basin) are being monitored during an ongoing, long-term (fiveyear) field program. The study combines hypothesis testing of platform effects...

Origin of solutes in saline lakes and springs on the Southern High Plains of Texas and New Mexico
W. Wood, B.F. Jones
Thomas C. Gustavson, editor(s)
1990, Book chapter, Geologic framework and regional hydrology: Upper Cenozoic Blackwater Draw and Ogallala Formations, Great Plains
Analysis of hydraulic heads, calculation of pore volume flushing, and analysis of solute and isotopic chemistry strongly suggest that the solutes originate from the concentration by evaporation of runoff and potable shallow ground water that discharges from the High Plains aquifer. Chloride/bromide solute ratios, which are thought to be unaffected...

Monitoring the hydrologic system for potential effects of geothermal and ground-water development in the Long Valley caldera, Mono County, California, U.S.A
Christopher Farrar, Daniel Lyster
1990, Conference Paper, Transactions - Geothermal Resources Council
In the early 1980's, renewed interest in the geothermal potential of the Long Valley caldera, California, highlighted the need to balance the benefits of energy development with the established recreational activities of the area. The Long Valley Hydrologic Advisory Committee, formed in 1987, instituted a monitoring program to collect data...
Hydrogeologic implications of increased septic-tank-soil-absorption system density, Ogden Valley, Weber County, Utah

1990, Conference Paper
Ground water in Ogden Valley occurs in perched, confined, and unconfined aquifers in the valley fill to depths of 600 feet and more. The confined aquifer, which underlies only the western portion of the valley, is overlain by cleyey silt lacustrine sediments probably deposited during the Bonneville Basin's Little Valley...
