A preliminary assessment of geologic framework and sediment thickness studies relevant to prospective US submission on extended continental shelf
Deborah R. Hutchinson, Jonathan R. Childs, Erika Hammar-Klose, Shawn Dadisman, N. Terrence Edgar, Ginger A. Barth
2004, Open-File Report 2004-1447
Under the provisions of Articles 76 and 77 of the United Nations Convention on the Law of the Sea (UNCLOS), coastal States have sovereign rights over the continental shelf territory beyond 200-nautical mile (nm) from the baseline from which the territorial sea is measured if certain conditions are met regarding...
Channel-morphology data for the Tongue River and selected tributaries, southeastern Montana, 2001-02
Katherine J. Chase
2004, Open-File Report 2004-1260
Coal-bed methane exploration and production have begun within the Tongue River watershed in southeastern Montana. The development of coal-bed methane requires production of large volumes of ground water, some of which may be discharged to streams, potentially increasing stream discharge and sediment load. Changes in stream discharge or sediment load...
Airborne Digital Sensor System and GPS-aided inertial technology for direct geopositioning in rough terrain
Richard D. Sanchez
2004, Open-File Report 2004-1391
High-resolution airborne digital cameras with onboard data collection based on the Global Positioning System (GPS) and inertial navigation systems (INS) technology may offer a real-time means to gather accurate topographic map information by reducing ground control and eliminating aerial triangulation. Past evaluations of this integrated system over relatively flat terrain...
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...
Is the extraction of thorium onto MnO2-coated filter cartridges uniform?
Peter W. Swarzenski, M. Baskaran
2004, Open-File Report 2004-1421
Large-volume (i.e., 102 - 103 L) seawater samples are traditionally required to study the partitioning of particle-reactive radionuclides between solution and size-fractionated particulate matter. One of the most frequently used methods to preconcentrate the short-lived isotopes of Th (234Th and 228Th) from such large volumes of water involves the effective...
Mineral production and mining trends for selected non-fuel commodities in Idaho and Montana, 1905-2001
Jeremy C. Larsen, Keith R. Long, Kenneth C. Assmus, Michael L. Zientek
2004, Open-File Report 2004-1414
Idaho and Montana state mining statistics were obtained from historical mineral production records and compiled into a continuous record from 1905 through 2001. To facilitate comparisons, the mineral production data were normalized by converting the units of measure to metric tons for all included commodities. These standardized statistical data include...
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...
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...
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...
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...
