Simulated water sources and effects of pumping on surface and ground water, Sagamore and Monomoy flow lenses, Cape Cod, Massachusetts
Donald A. Walter, Ann T. Whealan
2005, Scientific Investigations Report 2004-5181
The sandy sediments underlying Cape Cod, Massachusetts, compose an important aquifer that is the sole source of water for a region undergoing rapid development. Population increases and urbanization on Cape Cod lead to two primary environmental effects that relate directly to water supply: (1) adverse effects of land use...

A Cenozoic diffuse alkaline magmatic province (DAMP) in the southwest Pacific without rift or plume origin
Carol A. Finn, R. Dietmar Muller, Kurt S. Panter
2005, Geochemistry, Geophysics, Geosystems (6)
Common geological, geochemical, and geophysical characteristics of continental fragments of East Gondwana and adjacent oceanic lithosphere define a long-lived, low-volume, diffuse alkaline magmatic province (DAMP) encompassing the easternmost part of the Indo-Australian Plate, West Antarctica, and the southwest portion of the Pacific Plate. A key to generating the Cenozoic magmatism...
Threats, conservation strategies, and prognosis for suckers (Catostomidae) in North America: insights from regional case studies of a diverse family of non-game fishes
Steven J. Cooke, Christopher M. Bunt, Steven J. Hamilton, Cecil A. Jennings, Micheal P. Pearson, Michael S. Cooperman, Douglas F. Markle
2005, Biological Conservation (121) 317-331
Catostomid fishes are a diverse family of 76+ freshwater species that are distributed across North America in many different habitats. This group of fish is facing a variety of impacts and conservation issues that are somewhat unique relative to more economically valuable and heavily managed fish species. Here, we present...
Arsenic, microbes and contaminated aquifers
Ronald S. Oremland, John F. Stolz
2005, Trends in Microbiology (13) 45-49
The health of tens of millions of people world-wide is at risk from drinking arsenic-contaminated well water. In most cases this arsenic occurs naturally within the sub-surface aquifers, rather than being derived from identifiable point sources of pollution. The mobilization of arsenic into the aqueous phase is the first crucial...
Water resources data, Arkansas, 2004
T.H. Brossett, T.P. Schrader, D.A. Evans
2005, Water Data Report AR-04-1
The U.S. Geological Survey Arkansas Water Science Center, in cooperation with State, Federal, and other local governmental agencies, obtains a large amount of data pertaining to the water resources of Arkansas each year. These data, accumulated during many water years, constitute a valuable database for developing an improved understanding of...

Structure and mechanics of the San Andreas–San Gregorio fault junction, San Francisco, California
Tom Parsons, Terry R. Bruns, Ray W. Sliter
2005, Geochemistry, Geophysics, and Geosystems (6)
[1] The right‐lateral San Gregorio and San Andreas faults meet west of the Golden Gate near San Francisco. Coincident seismic reflection and refraction profiling across the San Gregorio and San Andreas faults south of their junction shows the crust between them to have formed shallow extensional basins that are dissected...
Summary of suspended-sediment concentration data, San Francisco Bay, California, Water Year 2003
Paul A. Buchanan, Neil K. Ganju
2005, Data Series 113
Suspended-sediment concentration data were collected in San Francisco Bay during water year 2003 (October 1, 2002-September 30, 2003). Optical sensors and water samples were used to monitor suspended-sediment concentration at two sites in Suisun Bay, three sites in San Pablo Bay, one site in Central San Francisco Bay, and three...

2005, Scientific Investigations Report 2005-5002
During May and June 2003, the U.S. Geological Survey installed monitoring wells and collected data to characterize the effectiveness of natural attenuation processes for remediating petroleum-contaminated ground water at Operable Unit A of the former Naval complex on Adak Island, Alaska. In addition, the evidence for petroleum biodegradation in ground...
Development of a local meteoric water line for southeastern Idaho, western Wyoming, and south-central Montana
Lyn Benjamin, LeRoy L. Knobel, L. Flint Hall, L. DeWayne Cecil, Jaromy R. Green
2005, Scientific Investigations Report 2004-5126
Linear-regression analysis was applied to stable hydrogen (H) and oxygen (O) isotope data in 72 snow-core and precipitation samples collected during 1999-2001 to determine the Local Meteoric Water Line (LMWL) for southeastern Idaho, western Wyoming, and south-central Montana. On the basis of (1) residuals from the regression model, (2) comparison...
Summary of sediment data from the Yampa river and upper Green river basins, Colorado and Utah, 1993-2002
John G. Elliott, Steven P. Anders
2005, Scientific Investigations Report 2004-5242
The water resources of the Upper Colorado River Basin have been extensively developed for water supply, irrigation, and power generation through water storage in upstream reservoirs during spring runoff and subsequent releases during the remainder of the year. The net effect of water-resource development has been to substantially modify the...
Direct measurement of methane hydrate composition along the hydrate equilibrium boundary
S. Circone, Stephen H. Kirby, Laura A. Stern
2005, Journal of Physical Chemistry B (109) 9468-9475
The composition of methane hydrate, namely nw for CH4·nwH2O, was directly measured along the hydrate equilibrium boundary under conditions of excess methane gas. Pressure and temperature conditions ranged from 1.9 to 9.7 MPa and 263 to 285 K. Within experimental error, there is no change in hydrate composition with increasing pressure along...
