Characteristics of the Alaskan 1-Km Advanced Very High Resolution Radiometer data sets used for analysis of vegetation biophysical properties
Carl J. Markon
1999, Open-File Report 99-401
In this study, data characteristics for composited, multitemporal Advanced Very High Resolution Radiometer data sets for Alaska were assessed for a 7- year period from 1991 to 1997. This involved consideration of the satellite sensors used, data processing performed, and data set compilation, along with an analysis of acquisition date,...
Digital Map of Surficial Geology, Wetlands, and Deepwater Habitats, Coeur d'Alene River Valley, Idaho
Arthur A. Bookstrom, Stephen E. Box, Berne L. Jackson, Theodore R. Brandt, Pamela D. Derkey, Steven R. Munts
1999, Open-File Report 99-548
The Coeur d'Alene (CdA) River channel and its floodplain in north Idaho are mostly covered by metal-enriched sediments, partially derived from upstream mining, milling and smelting wastes. Relative to uncontaminated sediments of the region, metal-enriched sediments are highly enriched in silver, lead, zinc, arsenic, antimony and mercury, copper, cadmium, manganese,...
Digital mining claim density map for federal lands in Arizona: 1996
Paul C. Hyndman, Harry W. Campbell
1999, Open-File Report 99-406
This report describes a digital map generated by the U.S. Geological Survey (USGS) to provide digital spatial mining claim density information for federal lands in Arizona as of March 1997. Mining claim data is earth science information deemed to be relevant to the assessment of historic, current, and future ecological,...
Preliminary aeromagnetic anomaly map of California
Carter W. Roberts, Robert C. Jachens
1999, Open-File Report 99-440
The magnetization in crustal rocks is the vector sum of induced in minerals by the Earth’s present main field and the remanent magnetization of minerals susceptible to magnetization (chiefly magnetite) (Blakely, 1995). The direction of remanent magnetization acquired during the rock’s history can be highly variable. Crystalline rocks generally contain...
Sources of springs supplying base flow to the Verde River headwaters, Yavapai County, Arizona
Laurie Wirt, H. W. Hjalmarson
1999, Open-File Report 99-378
Multiple lines of evidence were used to identify source aquifers, quantify their respective contributions, and trace the ground-water flow paths that supply base flow to the uppermost reach of the Verde River in Yavapai County, Arizona. Ground-water discharge via springs provides base flow for a 24-mile long reach from the mouth of Granite Creek (river mile 2.0)...
Mapping the glacial geology of the Central Great Lakes region in three dimensions: A model for state-federal cooperation
Richard C. Berg, Ned K. Bleuer, Berwyn E. Jones, Kevin A. Kincare, Richard R. Pavey, Byron D. Stone
1999, Open-File Report 99-349
Planners need to evaluate complex and competing public-policy options for managing water, land, and biological resources; they must ensure economic growth, meet the needs of an increasing population, assess hazards, and manage the environment in a sustainable manner. The State Geological Surveys of Illinois, Indiana, Michigan, and Ohio and the...
Archive of 15 cubic inch water gun data collected during USGS Cruise ALPH98013, New York Bight, 10-22, September, 1998
D.S. Foster, W. C. Schwab, W. W. Danforth, J. F. Denny, J. C. Hill, B.J. Irwin, D.R. Nichols, T.F. O’Brien
1999, Open-File Report 99-395
BackgroundThis CD-ROM contains copies of the navigation and field water gun subbottom data collected aboard the F/V Alpha & Omega II. The USGS Cruise ALPH98013 was conducted from 10-22 September, 1998, and is a collaborative involving the U.S Army Corps of Engineers, New York District and the United States Geological...
Digital elevation model (DEM) of Cascadia, latitude 39N-53N, longitude 116W-133W
Ralph A. Haugerud
1999, Open-File Report 99-369
This report contains a 250-meter digital elevation model (DEM) for Cascadia (latitude 39N - 53N, longitude 116W - 133W), a region that encompasses the Cascade volcanic arc, the Cascadia subduction zone, and the Juan de Fuca Ridge system. The DEM is distributed as file cascdem.tar.gz (39 MB; 78MB uncompressed)....
Geological map of Washington - Southwest quadrant (digital edition)
Timothy J. Walsh, Michael A. Korosec, William M. Phillips, Robert L. Logan, Henry W. Schasse, Karen L. Meagher, Ralph A. Haugerud
1999, Open-File Report 99-382
This report comprises digital spatial data that constitute a partial transcription of the 1:250,000-scale Geologic map of Washington - southwest quadrant (Walsh and others, 1987); digital base material, symbolsets, and ARC Macro Language (AML) procedures to create a geologic map on a shaded-relief base from the digital spatial data; and...
Total petroleum systems of the Bonaparte Gulf Basin area, Australia; Jurassic, Early Cretaceous-Mesozoic; Keyling, Hyland Bay-Permian; Milligans-Carboniferous, Permian
M.G. Bishop
1999, Open-File Report 99-50-P
The Bonaparte Gulf Basin Province (USGS #3910) of northern Australia contains three important hydrocarbon source-rock intervals. The oldest source-rock interval and associated reservoir rocks is the Milligans-Carboniferous, Permian petroleum system. This petroleum system is located at the southern end of Joseph Bonaparte Gulf and includes both onshore and offshore areas...
Environmental issues associated with fossil fuel resources; an evaluation of research opportunities for the U.S. Geological Survey's Energy Resources Program
M. L. Tuttle, G. N. Breit, Richard G. Stanley, R. B. Finkelman, E. I. Robbins, C. B. Cecil
1999, Open-File Report 99-590
Fossil fuel consumption in the United States has nearly tripled within the last 50 years (fig. 1), and is expected to continue increasing. As our knowledge and awareness of environmental consequences related to fossil fuel extraction and use grow, we as a nation, face the challenge of balancing our energy...
