2005, Book chapter, Amphibian declines: The conservation status of United States species
Many species of amphibians have declined substantially in distribution or number of populations in the United States and globally, and a variety of anthropogenic and natural factors have been suggested as causal agents in these declines. Evidence for the causal action of these agents derives from many types of sources,...

South Fork Iowa River watershed selected for a national water-quality study
M.L. Erwin, Stephen J. Kalkhoff
2005, Fact Sheet 2005-3064
The U.S. Geological Survey (USGS) is studying seven watersheds across the Nation to better understand how natural factors and agricultural management practices (AMPs) affect the transport of water and chemicals. Natural factors include climate and landscape (soil type, topography, geology), and AMPs include practices related to tillage, irrigation, and chemical...

Las Vegas and Pahrump are two of the fastest growing cities in the US, and the shortage of water looms as among the greatest future problems for these cities. These new maps of the Las Vegas 30 x 60-minute quadrangle provide a geologic and geophysical framework and fundamental earth...
Comparison of diffusion- and pumped-sampling methods to monitor volatile organic compounds in ground water, Massachusetts Military Reservation, Cape Cod, Massachusetts, July 1999–December 2002
Stacey A. Archfield, Denis R. LeBlanc
2005, Scientific Investigations Report 2005-5010
To evaluate diffusion sampling as an alternative method to monitor volatile organic compound (VOC) concentrations in ground water, concentrations in samples collected by traditional pumped-sampling methods were compared to concentrations in samples collected by diffusion-sampling methods for 89 monitoring wells at or near the Massachusetts Military Reservation, Cape Cod. Samples...

The New Hampshire watershed tool: a geographic information system tool to estimate streamflow statistics and ground-water-recharge rates
Scott A. Olson, Robert H. Flynn, Craig M. Johnston, Gary D. Tasker
2005, Open-File Report 2005-1172
Estimates of low-flow statistics, flow durations, and ground-water-recharge rates are needed to assist water-resource managers in assessing surface-water resources and ground-water availability. Often these estimates are required at ungaged sites where no observed streamflow data are available for analysis. Regression equations for estimating low-flow statistics and flow durations, and for...
Correlated declines in Pacific arctic snow and sea ice cover
Robert P. Stone, David C. Douglas, Gennady I. Belchansky, Sheldon Drobot
2005, Arctic Research of the United States (19) 18-25
Simulations of future climate suggest that global warming will reduce Arctic snow and ice cover, resulting in decreased surface albedo (reflectivity). Lowering of the surface albedo leads to further warming by increasing solar absorption at the surface. This phenomenon is referred to as “temperature–albedo feedback.” Anticipation of such a feedback...

Monitoring of oceanographic properties of Glacier Bay, Alaska 2004
Erica N. Madison, Lisa L. Etherington
2005, Report
Glacier Bay is a recently (300 years ago) deglaciated fjord estuarine system that has multiple sills, very deep basins, tidewater glaciers, and many streams. Glacier Bay experiences a large amount of runoff, high sedimentation, and large tidal variations. High freshwater discharge due to snow and ice melt and the presence...
S-wave refraction survey of alluvial aggregate
Karl J. Ellefsen, Gary J. Tuttle, Jackie M. Williams, Jeffrey E. Lucius
2005, Scientific Investigations Report 2005-5012
An S-wave refraction survey was conducted in the Yampa River valley near Steamboat Springs, Colo., to determine how well this method could map alluvium, a major source of construction aggregate. At the field site, about 1 m of soil overlaid 8 m of alluvium that, in turn, overlaid sedimentary bedrock....
Vitrinite reflectance data for the Permian Basin, west Texas and southeast New Mexico

Effects of aquifer heterogeneity on ground-water flow and chloride concentrations in the Upper Floridan aquifer near and within an active pumping well field, west-central Florida
A. B. Tihansky
2005, Scientific Investigations Report 2004-5268
Chloride concentrations have been increasing over time in water from wells within and near the Eldridge-Wilde well field, near the coast in west-central Florida. Variable increases in chloride concentrations from well to well over time are the combined result of aquifer heterogeneity and ground-water pumping within the Upper Floridan aquifer....
