W. D. Stanley, W. J. Gwilliam, Gary Latham, Keith Westhusing
1992, American Association of Petroleum Geologists Bulletin (76) 1569-1585
Geophysical studies in the southern Washington Cascades have outlined a possible, previously unrecognized sequence of sedimentary rocks. These postulated sedimentary units are interpreted to correspond to at least the upper section of a low-resistivity (high-conductivity) assemblage of rocks at depths of 1-10 km and with thicknesses up to 15 km...

C.E. Kirschner, Arthur Grantz, M. W. Mullen
1992, American Association of Petroleum Geologists Bulletin (76) 651-679
Geophysical and subsurface geologic data suggest that the Avak structure, which underlies the Arctic Coastal Plain 12 km southeast of Barrow, Alaska, is a hypervelocity meteorite or comet impact structure. The structure is a roughly circular area of uplifted, chaotically deformed Upper Triassic to Lower Cretaceous sedimentary rocks 8 km...

It has been estimated in previous studies that 23 square miles of the Oxnard aquifer, a member of a multi-layered aquifer system beneath the Oxnard plain in Ventura County, California, has been contaminated as a result of seawater intrusion. To investigate this and other potential sources of saline water, a...
Hydrogeology of the surficial aquifer system, Dade County, Florida
J.E. Fish, M.T. Stewart
1991, Water-Resources Investigations Report 90-4108
An investigation of the surficial aquifer system in Dade County, begun in 1983, is part of a regional study of the aquifer system in southeastern Florida. Test drilling for lithologic samples, flow measurements during drilling, aquifer testing, and analyses of earlier data permitted delineation of the hydraulic conductivity distribution (on...
Lead exposure in Canada geese of the eastern prairie population
S. DeStefano, C. J. Brand, D. H. Rusch, Daniel L. Finley, Murray M. Gillespie
1991, Wildlife Society Bulletin (19) 23-32
We monitored lead exposure in Eastern Prairie Population Canada geese during summer-winter, 1986-1987 and 1987-1988 at 5 areas. Blood lead concentrations in geese trapped during summer at Cape Churchill Manitoba were below levels indicative of recent lead exposure (0.18 ppm). Geese exposed to lead (≥0.18 ppm blood lead) increased to...
Gray wolf density and its association with weights and hematology of pups from 1970 to 1988
Glenn D. DelGiudice, L. David Mech, U.S. Seal
1991, Journal of Wildlife Diseases (27) 630-636
We examined weights and hematologic profiles of gray wolf (Canis lupus) pups and the associated wolf density in the east-central Superior National Forest of northeastern Minnesota (USA) during 1970 to 1988. We collected weight and hematologic data from 117 pups (57 females, 60 males) during 1 September to 22 November...
Sedimentary facies and depositional environments of early Mesozoic Newark Supergroup basins, eastern North America
J. P. Smoot
1991, Palaeogeography, Palaeoclimatology, Palaeoecology (84) 369-423
The early Mesozoic Newark Supergroup consists of continental sedimentary rocks and basalt flows that occupy a NE-trending belt of elongate basins exposed in eastern North America. The basins were filled over a period of 30–40 m.y. spanning the Late Triassic to Early Jurassic, prior to the opening of the north...

1991, Water Data Report NY-90-1
Water resources data for the 1990 water year for New York consist of records of stage, discharge, and water quality of streams; stage, contents, and water quality of lakes and reservoirs; and water levels in observation wells. This volume contains records of water discharge at 97 gaging stations; stage only...
Hydrology of the Texas Gulf Coast aquifer systems
Paul D. Ryder, Ann F. Ardis
1991, Open-File Report 91-64
A complex, multilayered ground-water flow system exists in the Coastal Plain sediments of Texas. The Tertiary and Quaternary clastic deposits have an areal extent of 114,000 square miles onshore and in the Gulf of Mexico. Two distinct aquifer systems are recognized within the sediments, which range in thickness from a...

G. A. Payne
1991, Water-Resources Investigations Report 88-4016
Water-quality investigations in six interconnected lakes that comprise most of the surface area of Voyageurs National Park in northern Minnesota revealed substantial differences in water-quality. Three large lakes; Sand Point, Namakan, and Rainy, near the eastern and northern boundaries of the Park; are oligotrophic to mesotrophic, having low dissolved solids...
Earth-fissure movements associated with fluctuations in ground-water levels near the Picacho Mountains, south-central Arizona, 1980-84
Michael C. Carpenter
1991, Open-File Report 90-561
The Picacho earth fissure transects subsiding alluvial sediments near the east periphery of the Picacho basin in south-central Arizona. The basin has undergone land subsidence of as much as 3.8 meters since the 1930's owing to compaction of the aquifer system in response to ground-water-level declines that have exceeded 100...

Use of Landsat imagery to estimate ground-water pumpage for irrigation on the Columbia Plateau in eastern Washington, 1985
P. C. Van Metre, Paul Seevers
1991, Water-Resources Investigations Report 89-4157
A method for estimating ground-water pumpage for irrigation was developed for the Columbia Plateau in eastern Washington. The method combines water-application rates estimated from pumpage data with acreage of irrigated crops that was mapped by using Landsat imagery. The study area consisted of Grant, Lincoln, Adams, and Franklin Counties, an...
