Integrated geophysical characterization of the Winthrop Landfill Southern Flow Path, Winthrop, Maine
Cian B. Dawson, John W. Lane Jr., Eric A. White, Marcel Belaval
None, Conference Paper, Proceedings: Symposium on the application of geophysics to engineering and environmental problems
The U.S. Geological Survey (USGS), in cooperation with United Technologies Corporation, used an integrated suite of borehole, surface, and water-borne geophysical methods near the site of the former Winthrop Landfill, Winthrop, Maine, to investigate the hydrogeology controlling the transport of leachate from the landfill to nearby Annabessacook Lake. During the...
Perspectives on the diagnosis, epizootiology, and control of the 1973 duck plague epizootic in wild waterfowl at Lake Andes, South Dakota
Gary L. Pearson, Delmar R. Cassidy
None, Journal of Wildlife Diseases (33 ) 681-705
An epizootic of duck plague occurred in early 1973 in a population of 163,500 wild waterfowl, primarily mallards (Anas platyrhynchos), wintering on Lake Andes and the nearby Missouri River in southeastern South Dakota (USA). The diagnosis was based on pathologic lesions and confirmed by virus isolation. Control measures included quarantine, attempts...
Exsolved magmatic fluid and its role in the formation of comb-layered quartz at the Cretaceous Logtung W-Mo deposit, Yukon Territory, Canada
Jacob B. Lowenstern, W. David Sinclair
None, Book chapter, The Third Hutton symposium on the origin of granites and related rocks
Comb-layered quartz is a type of unidirectional solidification texture found at the roofs of shallow silicic intrusions that are often associated spatially with Mo and W mineralisation. The texture consists of multiple layers of euhedral, prismatic quartz crystals (Type I) that have grown on subplanar aplite substrates. The layers are...
Geodetic monitoring of the southern San Andreas Fault, California, 1980-1991
James C. Savage, Michael Lisowski
None, Journal of Geophysical Research (100) 8185-8192
Five geodetic arrays (10 to 40 km aperture) located along the San Andreas fault have been surveyed frequently (several times in most years) over the 1980–1991 interval to detect possible fluctuations in the deformation rate. In each survey of an array the distances between the same four to seven pairs...
The ecology of Humboldt Bay, California, an estuarine profile
R.A. Barnhart, M.J. Boyd , J.E. Pequegnat
None, Report
Synthesizes data on the ecological relationships and functions of the estuary, including information on physical aspects of the bay environment; describes the biotic communities and their relationships; provides management considerations in terms including environmental concerns; and identifies research and management information gaps. Portions of the bay are managed as a national wildlife...
Storm‐dominated bottom boundary layer dynamics on the Northern California Continental Shelf: Measurements and predictions
D.A. Cacchione, W.D. Grant, D.E. Drake, S.M. Glenn
None, Journal of Geophysical Research C: Oceans (92) 1817-1827
Measurements of near‐bottom velocity profiles in 85 m water depth during a storm on the continental shelf off northern California using the GEOPROBE tripod in December 1979 provided estimates of shear velocities, , and roughness lengths, , when the near‐bottom velocity profiles were logarithmic. These estimates agree within 90% confidence...
Vegetation pattern on channel features in the Passage Creek Gorge, Virginia
Cliff R. Hupp
None, Castanea (48) 62-72
Persistent distribution patterns of woody vegetation within the bottomland forest of Passage Creek, Virginia, were related to fluvial landforms, channel geometry, streamflow characteristics, and sediment-size characteristics. Vegetation patterns were determined from species presence as observed in...
PIERRE PERRAULT: THE MAN AND HIS CONTRIBUTION TO MODERN HYDROLOGY
R. L. Nace
None, JAWRA (10) 633-647
ABSTRACT: Pierre Perrault, member of a bourgeois provincial family whose roots were in the Touraine region of France, grew up in Paris. One of six illustrious Brothers, all characterized by brilliance and diversity, he was educated as a lawyer but turned to finance and rose to a high position under...
Relations between geological structure and aeromagnetic anomalies in central Nevada
Edwin S. Robinson
None, Bulletin of the Geological Society of America (81) 2045-2060
An aeromagnetic survey of a 6000-km2 area in central Nevada has been complied by the U.S. Geological Survey. An interpretation of the aeromagnetic data is developed to establish relations between near-surface geological features and structure extending to intermediate depths in the crust.A three-dimensional distribution of magnetized material is described which would...
Xenoliths in the honolulu volcanic series, Hawaii
E. D. Jackson, T. L. Wright
None, Journal of Petrology (11) 405-433
The Pleistocene to Holocene Honolulu Volcanic Series was erupted from about 37 vents scattered over the older Koolau tholeiite shield. The rocks of this series are compositionally zoned with respect to the shield; near the Koolau caldera the predominant rocks are melilitenepheline basalts, but these give way outward to nepheline...
Garnet types from the Cazadero area, California
D. E. Lee, R. G. Coleman, Richard C. Erd
None, Journal of Petrology (4) 460-492
This is the third in a series of papers on glaucophane schists from the Franciscan Formation near Cazadero, California. Previous papers describe three distinct types of glaucophane-bearing Franciscan metamorphic rocks near Cazadero.The purpose of this study is to investigate the garnets present in metamorphic types III (bedrock schists)...
Effect on evaporation of releases from reservoirs on Salt River, Arizona
G.E. Koberg
None, International Association of Scientific Hydrology - Bulletin (5) 37-44
By means of the energy-budget method, measurements of evaporation losses from four reservoirs on Salt River, Ariz., were determined to range from 57.5 to 69.9 inches for the 12-month period April 1958 to March 1959. Water is withdrawn from Roosevelt Lake at considerable depth and released through three run-of-the-river reservoirs. Because...
