Earthquake damage in greater Los Angeles
1995, Open-File Report 95-693
Generalized regions of highest damage from three Los Angeles area earthquakes of the 20th century. The area of highest damage from the 1971 San Fernando earthquake, not shown, lay mostly within the area that experience high damage in 19947. The map illustrates that moderate magnitude earthquakes can produce series effects...
Coal resources in environmentally-sensitive lands under federal management
William D. Watson, John K. Tully, Edward N. Moser, David P. Dee, Karen Bryant, Richard Schall, Harold A. Allan
1995, Open-File Report 95-631
This report presents estimates of coal-bearing acreage and coal tonnage in environmentally-sensitive areas. The analysis was conducted to provide data for rulemaking by the Federal Office of Surface Mining (Watson and others, 1995). The rulemaking clarifies conditions under which coal can be mined in environmentally-sensitive areas. The area of the...
Ground-water resources of Kings and Queens Counties, Long Island, New York
Herbert T. Buxton, Peter K. Shernoff
1995, Open-File Report 92-76
The aquifers beneath Kings and Queens Counties supplied an average of more than 120 Mgal/d (million gallons per day) for industrial and public water supply during 1904-47, but this pumping caused saltwater intrusion and a deterioration of water quality that led to the cessation of pumping for public supply in...
U.S. Geological Survey Federal-State Cooperative Water-Resources Program fiscal year 1994
Bruce K. Gilbert
1995, Open-File Report 95-332
The Federal-State Cooperative Program is a major U.S. Geological Survey (USGS) activity for the collection, analysis, and reporting of information on the quantity, quality, and use of the Nation's water resources. The fundamental characteristic of the program is that most of the work is undertaken by the USGS through joint-funding...
Maps showing isotopic composition of methane in seawater of the Alaskan Beaufort Sea, 1994
Thomas D. Lorenson, Keith A. Kvenvolden, Peter W. Barnes, Brian N. Popp, Frank J. Sansone, Terri M. Rust, Marvin D. Lilley, Eric J. Olson
1995, Open-File Report 95-669
We are engaged in a five-year study to test the hypothesis that methane from decomposing gas hydrates may contribute methane to the atmosphere. The release of methane, a "greenhouse" gas, can enhance global warming and be a factor in global climate change. As part of the study we have measured the...
Quality-assurance plan for water-resources activities of the U.S. Geological Survey in Montana--1995
Joe A. Moreland
1995, Open-File Report 91-194
As the Nation's principal earth-science information agency, the U.S. Geological Survey has developed a worldwide reputation for collecting accurate data and producing factual, impartial interpretive reports. To ensure continued confidence in the pro- ducts, the Water Resources Division of the U.S. Geological Survey has implemented a policy that all scientific...
Well-integrity survey (Phase II) of abandoned homestead water wells in the High Plains aquifer, former Pantex Ordance Plant and Texas Tech Research Farm near Amarillo, Texas, 1995
Glenn A. Rivers
1995, Open-File Report 95-751
This report describes the methods used and the results obtained during a field search for abandoned homestead sites and water wells at the former Pantex Ordnance Plant and Texas Tech Research Farm (Pantex site) near Amarillo, Texas. The search was the second phase of a three-phase well-integrity survey at the...
Overview of the National Water-Quality Assessment Program
P.P. Leahy, T. H. Thompson
1994, Open-File Report 94-70
The Nation's water resources are the basis for life and our economic vitality. These resources support a complex web of human activities and fishery and wildlife needs that depend upon clean water. Demands for good-quality water for drinking, recreation, farming, and industry are rising, and as a result, the American...
High-resolution single-channel seismic reflection surveys of Orange Lake and other selected sites of north central Florida
Jack L. Kindinger, Jeffrey B. Davis, James G. Flocks
1994, Open-File Report 94-616
The potential fluid exchange between lakes of north central Florida and the Floridan aquifer and the process by which exchange occurs is of critical concern to the St. Johns Water Management District. High-resolution seismic tools with relatively new digital technology were utilized in collecting geophysical data from Orange, Kingsley, Lowry...
Water fact sheet; evolution of sediment yield from Mount St. Helens, Washington, 1980-1993
John E. Costa
1994, Open-File Report 94-313
The most enduring geological consequence of the eruption of Mount St. Helens, Washington, on May 18, 1980, and the most costly single element in the recovery effort, has been the persistent downstream sedimentation caused by erosion of the approximately 3 cubic kilometers (km3) of sediment deposited on the landscape surrounding...
ANALOG: a program for estimating paleoclimate parameters using the method of modern analogs
Peter N. Schweitzer
1994, Open-File Report 94-645
Beginning in the 1970s with CLIMAP, paleoclimatologists have been trying to derive quantitative estimates of climatic parameters from the sedimentary record. In general the procedure is to observe the modern distribution of some component of surface sediment that depends on climate, find an empirical relationship between climate and the character...
Quality of surface and ground water in the White Creek and Mossy Creek watersheds, White County, Georgia, 1992-93
Michael F. Peck, Jerry W. Garrett
1994, Open-File Report 94-540
Surface- and ground-water quality data were collected and evaluated from streams and wells in the White Creek and Mossy Creek watersheds in White County, Georgia, during three sampling periods in 1992 and 1993, to identify stream reaches and wells affected by nonpoint-source contaminants. Livestock operations in these watersheds account for...
