Feral Cats: Too Long a Threat to Hawaiian Wildlife
Steven C. Hess, Paul C. Banko
2006, Fact Sheet 2006-3006
BACKGROUND Domestic cats (Felis catus) were first brought to Hawai`i aboard sailing ships of European explorers and colonists. The job of these predators was to control mice and rats on the ships during the long voyages. As in other places, cats were taken in and adopted by the families of Hawai`i...
The 20th-Century Topographic Survey as Source Data for Long-Term Landscape Studies at Local and Regional Scales
Dalia Varanka
2006, Open-File Report 2006-1002
Historical topographic maps are the only systematically collected data resource covering the entire nation for long-term landscape change studies over the 20th century for geographical and environmental research. The paper discusses aspects of the historical U.S. Geological Survey topographic maps that present constraints on the design of a database for...

Michael T. Koterba, A. Scott Andres, Joseph Vrabel, Dianna M. Crilley, Zoltan Szabo, John F. DeWild, George R. Aiken, Betzaida Reyes-Padro
2006, Scientific Investigations Report 2006-5011
In January 2001, mercury (Hg) was detected (500 nanograms per liter, ng/L, or greater) in the distribution system of the Long Neck Water Company (LNWC), Pot Nets, Delaware. By April 2001, two LNWC production wells had been taken off-line because discharge concentrations of total mercury (HgT) either had exceeded or...

Geoffrey S. Plumlee, Gregory P. Meeker, John K. Lovelace, Robert J. Rosenbauer, Paul J. Lamothe, Edward T. Furlong, Charles R. Demas
2006, Open-File Report 2006-1023
Introduction: The flooding in the greater New Orleans area that resulted from Hurricanes Katrina and Rita in September, 2005, left behind accumulations of sediments up to many centimeters thick on streets, lawns, parking lots, and other flat surfaces. These flood sediment deposits have been the focus of extensive...
Simulation of saltwater movement in the Upper Floridan aquifer in the Savannah, Georgia-Hilton Head Island, South Carolina, area, predevelopment-2004, and projected movement for 2000 pumping conditions
Alden M. Provost, Dorothy F. Payne, Clifford I. Voss
2006, Scientific Investigations Report 2006-5058
A digital model was developed to simulate ground-water flow and solute transport for the Upper Floridan aquifer in the Savannah, Georgia–Hilton Head Island, South Carolina, area. The model was used to (1) simulate trends of saltwater intrusion from predevelopment to the present day (1885–2004), (2) project these trends from the...

2006, Open-File Report 2006-1063
Introduction: The Republic of the Philippines has some 19 coal districts that contain coal deposits ranging from Eocene to Pleistocene in age. These coal districts include: (1) Catanduanes (Eocene); (2) Cebu, Zamboanga Sibuguey, Bukidnon, Maguindanao, Sarangani, and Surigao (Oligocene to Miocene); (3) Batan Island, Masbate, Semirara (including Mindoro), and...
Benthic foraminifera from a relict flood tidal delta along the Virginia/North Carolina Outer Banks
Marci M. Robinson, R.A. McBride
2006, Micropaleontology (52) 67-80
Examination of benthic foraminifera from six vibracores collected from a relict flood tidal delta near the Virginia/North Carolina border documents the assemblages associated with a former inlet and provides geologic evidence of this former inlet that once defined the boundary between Virginia and North Carolina along the Outer Banks. Three...
Predicting toxic effects of copper on aquatic biota in mineralized areas by using the Biotic Ligand Model
Kathleen S. Smith, James F. Ranville, M. Adams, LaDonna M. Choate, Stan E. Church, David L. Fey, Richard B. Wanty, James G. Crock
2006, Conference Paper, Proceedings of the Seventh International Conference on Acid Rock Drainage
The chemical speciation of metals influences their biological effects. The Biotic Ligand Model (BLM) is a computational approach to predict chemical speciation and acute toxicological effects of metals on aquatic biota. Recently, the U.S. Environmental Protection Agency incorporated the BLM into their regulatory water-quality criteria for copper. Results from three...
Integrating bioavailability approaches into waste rock evaluations
James F. Ranville, E. P. Blumenstein, M. J. Adams, LaDonna M. Choate, Kathleen S. Smith, Thomas R. Wildeman
2006, Conference Paper, Proceedings of the Seventh International Conference on Acid Rock Drainage
The presence of toxic metals in soils affected by mining, industry, agriculture and urbanization, presents problems to human health, the establishment and maintenance of plant and animal habitats, and the rehabilitation of affected areas. A key to managing these problems is predicting the fraction of metal in a given soil...
Simulating Arctic climate warmth and icefield retreat in the last interglaciation
Bette L. Otto-Bliesner, Shawn J. Marshall, Jonathan T. Overpeck, Gifford H. Miller, Aixue Hu, P. Anderson, O. Bennike, J. Brigham-Grette, M. Duvall, M. Edwards, B. Frechette, S. Funder, S. Johnsen, J. Knies, R. Koerner, A.V. Lozhkin, G. MacDonald, J. Matthiessen, M. Montoya, Daniel R. Muhs, N. Reeh, H.P. Sejrup, C. Turner, A.A. Velichko
2006, Science (311) 1751-1753
In the future, Arctic warming and the melting of polar glaciers will be considerable, but the magnitude of both is uncertain. We used a global climate model, a dynamic ice sheet model, and paleoclimatic data to evaluate Northern Hemisphere high-latitude warming and its impact on Arctic...
Major- and trace-element concentrations in rock samples collected in 2004 from the Taylor Mountains 1:250,000-scale quadrangle, Alaska
Edward P. Klimasauskas, Marti L. Miller, Dwight Bradley, Susan M. Karl, James F. Baichtal, Robert B. Blodgett
2006, Open-File Report 2006-1070
The Kuskokwim mineral belt of Bundtzen and Miller (1997) forms an important metallogenic region in southwestern Alaska that has yielded more than 3.22 million ounces of gold and 400,000 ounces of silver. Precious-metal and related deposits in this region associated with Late Cretaceous to early Tertiary igneous complexes extend into...
Concepts and procedures required for successful reduction of tensor magnetic gradiometer data obtained from an unexploded ordnance detection demonstration at Yuma Proving Grounds, Arizona
Robert E. Bracken, Philip J. Brown II
2006, Open-File Report 2006-1027
On March 12, 2003, data were gathered at Yuma Proving Grounds, in Arizona, using a Tensor Magnetic Gradiometer System (TMGS). This report shows how these data were processed and explains concepts required for successful TMGS data reduction. Important concepts discussed include extreme attitudinal sensitivity of vector measurements, low attitudinal sensitivity...

Raymond H. Johnson, Douglas B. Yager
2006, Open-File Report 2006-1030
In the late nineteenth century, San Juan County, Colorado, was the center of a metal mining boom in the San Juan Mountains. Although most mining activity ceased by the 1990s, the effects of historical mining continue to contribute metals to ground water and surface water. Previous research by the U.S....

County-level estimates of nutrient inputs to the land surface of the conterminous United States, 1982-2001
Barbara C. Ruddy, David L. Lorenz, David K. Mueller
2006, Scientific Investigations Report 2006-5012
Nutrient input data for fertilizer use, livestock manure, and atmospheric deposition from various sources were estimated and allocated to counties in the conterminous United States for the years 1982 through 2001. These nationally consistent nutrient input data are needed by the National Water-Quality Assessment Program for investigations of stream- and...
