Advanced systems data for mapping Emperor Penguin habitats in Antarctica
Richard D. Sanchez, Gerald L. Kooyman
2004, Open-File Report 2004-1379
Commercial orbital sensor systems combined with other resource data from the U.S. Geological Survey National Civil Applications Program (NCAP) may offer an effective way of mapping Emperor penguin habitats and their response to regional climate change in Antarctica. This project examined these resources to determine their applicability for mapping Emperor...
1999 Volcanic activity in Alaska and Kamchatka: Summary of events and response of the Alaska Volcano Observatory
Robert G. McGimsey, Christina A. Neal, Olga Girina
2004, Open-File Report 2004-1033
The Alaska Volcano Observatory (AVO) monitors 41 historically active volcanoes along the Aleutian Arc. Twenty are seismically monitored and for the rest, the AVO monitoring program relies mainly on daily analysis of satellite images, pilot reports, and observations of local residents and ship's crews. In 1999, AVO responded to eruptive...
Digital data used to relate nutrient inputs to water quality in the Chesapeake Bay watershed, version 3.0
John W. Brakebill, Stephen D. Preston
2004, Open-File Report 2004-1433
Chesapeake Bay restoration efforts are focused on improving water quality, living resources, and ecological habitats by 2010. One aspect of the water-quality restoration is the refinement of strategies designed to implement nutrient-reduction practices within the Bay watershed. These strategies are being refined and implemented by resource managers of the Chesapeake...
Water-resources investigations in Wisconsin, 2004
Jennifer L. Bruce, Michelle M. Greenwood, Susan Z. Jones
2004, Open-File Report 2004-1403
The statewide average precipitation for the 2003 water year was 27.42 inches, which was 5.22 inches less than the normal annual precipitation of 32.64 inches for water years 1971–2000. Average precipitation values affecting streamflow conditions ranged from 67 percent in southeast Wisconsin to 99 percent in northeast Wisconsin with a...
Surficial materials in the conterminous United States
David R. Soller, Marith C. Reheis
2004, Open-File Report 2003-275
Introduction: The Earth's bedrock is overlain in many places by a loosely compacted and mostly unconsolidated blanket of sediments in which soils commonly are developed. These sediments generally were eroded from underlying rock, and then were transported and deposited. In places, they exceed 1,000 ft (330 m) in thickness. Where...
Water-quality and lake-stage data for Wisconsin Lakes, water year 2003
W. J. Rose, H.S. Garn, G. L. Goddard, D.L. Olson, Dale M. Robertson
2004, Open-File Report 2004-1087
 The U.S. Geological Survey (USGS), in cooperation with local and other agencies, collects data at selected lakes throughout Wisconsin. These data, accumulated over many years, provide a data base for developing an improved understanding of the water quality of lakes. To make these data available to interested parties outside the...
Geologic map of the Reyes Peak quadrangle, Ventura County, California
Scott A. Minor
2004, Open-File Report 2004-1420
New 1:24,000-scale geologic mapping in the Cuyama 30' x 60' quadrangle, in support of the USGS Southern California Areal Mapping Project (SCAMP), is contributing to a more complete understanding of the stratigraphy, structure, and tectonic evolution of the complex junction area between the NW-trending Coast Ranges and EW-trending western Transverse...
Triangle area water supply monitoring project, October 1988 through September 2001, North Carolina -- description of the water-quality network, sampling and analysis methods, and quality-assurance practices
Carolyn J. Oblinger
2004, Open-File Report 2004-1278
The Triangle Area Water Supply Monitoring Project was initiated in October 1988 to provide long-term water-quality data for six area water-supply reservoirs and their tributaries. In addition, the project provides data that can be used to determine the effectiveness of large-scale changes in water-resource management practices, document differences in water...
