Preliminary volcano-hazard assessment for Kanaga Volcano, Alaska
Christopher F. Waythomas, Thomas P. Miller, Christopher J. Nye
2002, Open-File Report 2002-397
Kanaga Volcano is a steep-sided, symmetrical, cone-shaped, 1307 meter high, andesitic stratovolcano on the north end of Kanaga Island (51°55’ N latitude, 177°10’ W longitude) in the western Aleutian Islands of Alaska. Kanaga Island is an elongated, low-relief (except for the volcano) island, located about 35 kilometers west of the...
Analysis of geophysical logs from six boreholes at Lariat Gulch, former U.S. Air Force site PJKS, Jefferson County, Colorado
Frederick L. Paillet, Richard E. Hodges, Barbara S. Corland
2002, Open-File Report 2002-364
This report presents and describes geophysical logs for six boreholes in Lariat Gulch, a topographic gulch at the former U.S. Air Force site PJKS in Jefferson County near Denver, Colorado. Geophysical logs include gamma, normal resistivity, fluid-column temperature and resistivity, caliper, televiewer, and heat-pulse flowmeter. These logs were run in...
Water-quality, biological, and habitat assessment of the Boeuf River Basin, southeastern Arkansas, 1994-96
C. Shane Barks, James C. Petersen, Faron D. Usrey
2002, Water-Resources Investigations Report 2002-4187
Water-quality and biological samples were collected at several sites in the Boeuf River Basin between November 1994 and December 1996. Water-quality and benthic macroinvertebrate community samples were collected and habitat was measured once at 25 ambient monitoring sites during periods of seasonal low flow. Water-quality storm-runoff samples were collected during...
MTBE in groundwater of the U.S.: Occurrence, potential sources, and long-range transport
Michael J. Moran, John S. Zogorski, Paul J. Squillace
2002, Book chapter, Managing for healthy ecosystems
Groundwater is an important and valuable resource in the U.S. To some extent, groundwater is used in all 50 states to provide drinking water. In 1995, more than 50% of the population, more than 130 million people, relied on groundwater for drinking water supplies (Solley et al., 1998). About 30%,...
Grassland bird communities and environmental health: The role of landscape features
Douglas H. Johnson, S.F. Browder, Maiken Winter
2002, Book chapter, Managing for healthy ecosystems
Ecosystems throughout the world are imperiled by myriad anthropogenic factors. It is critical to develop tools for evaluating and monitoring the health or integrity of various ecosystems. Because of the broad scale of the problem, the urgency to address informational needs, and the limited financial resources committed to the problem,...
Application of landscape models to alternative futures analyses
A.C. Neale, K. Bruce Jones, Nash Maliha, Rick D. van Remortel, James D. Wickham, Kurt H. Riitters, Robert V. O’Neill
2002, Book chapter, Managing for healthy ecosystems
Scientists and environmental managers alike are concerned about broadscale changes in land use and landscape pattern and their cumulative impact on environmental and economic end points, such as water quality and quantity, species habitat, productivity, erosion potential, recreational value, and overall ecological health (Rapport et al., 1998). They also are...
Ground-water, surface-water, and water-chemistry data, Black Mesa Area, northeastern Arizona — 2000–2001, and performance and sensitivity of the 1988 USGS numerical model of the N aquifer
Blakemore E. Thomas
2002, Water-Resources Investigations Report 2002-4211
The N aquifer is the major source of water in the 5,400-square-mile area of Black Mesa in northeastern Arizona. Availability of water is an important issue in this area because of continued industrial and municipal use, a growing population, and precipitation of about 6 to 14 inches per year. The monitoring...
USGS Coal Desorption Equipment and a Spreadsheet for Analysis of Lost and Total Gas from Canister Desorption Measurements
Charles E. Barker, Todd A. Dallegge, Arthur C. Clark
2002, Open-File Report 2002-496
We have updated a simple polyvinyl chloride plastic canister design by adding internal headspace temperature measurement, and redesigned it so it is made with mostly off-the-shelf components for ease of construction. Using self-closing quick connects, this basic canister is mated to a zero-head manometer to make a simple coalbed methane...
Digital mapping techniques '02, workshop proceedings : May 19-22, 2002, Salt Lake City, Utah
David R. Soller
2002, Open-File Report 2002-370
The Digital Mapping Techniques '02 (DMT'02) workshop was attended by 101 technical experts from 43 agencies, universities, and private companies, including representatives from 25 state geological surveys (see Appendix A). This workshop was similar in nature to the previous five meetings, held in Lawrence, Kansas (Soller, 1997), in Champaign, Illinois...
Fifty-year flood-inundation maps for Nacaome, Honduras
David L. Kresch, M. C. Mastin, T. D. Olsen
2002, Open-File Report 2002-256
After the devastating floods caused by Hurricane Mitch in 1998, maps of the areas and depths of 50-year-flood inundation at 15 municipalities in Honduras were prepared as a tool for agencies involved in reconstruction and planning. This report, which is one in a series of 15, presents maps of areas...
