Warren F. Agena, Myung W. Lee, Patrick E. Hart
2001, Open-File Report 2001-330
Contained on this set of two CD-ROMs are stacked and migrated multi-channel seismic-reflection data for 44 lines recorded in the Chukchi Sea, northern Alaska, by the United States Geological Survey in 1977, 1978, and 1980. All data were reprocessed by the USGS in 2000 using updated methods. The resulting final...
Potentiometric surface, carbonate-rock province, southern Nevada and southeastern California, 1998-2000
J.W. Wilson
2001, Open-File Report 2001-335
The carbonate-rock aquifer that underlies most of southern Nevada occupies part of what is known as the carbonate-rock province, a physiographic region that encompasses the eastern two-thirds of the Great Basin. The potential for development of water resources in this aquifer has prompted Federal, State, and local authorities to seek...

Drilling, Construction, Water-Level, and Water-Quality Information for the Kualapuu Deep Monitor Well, 4-0800-01, Molokai, Hawaii
Delwyn S. Oki, Glenn R. Bauer
2001, Open-File Report 2001-350
A monitor well was completed in January 2001 by the U.S. Geological Survey in the Kualapuu area of central Molokai, Hawaii that allows for monitoring the thicknesses of the freshwater body and the upper part of the underlying freshwater-saltwater transition zone. The well was drilled in cooperation with the State...
Gravity data along LARSE (Los Angeles Regional Seismic Experiment) Line II, southern California
R .J. Wooley, V.E. Langenheim
2001, Open-File Report 2001-375
The U.S. Geological Survey conducted a detailed gravity study along part of the Los Angeles Regional Seismic Experiment (LARSE) transect across the San Fernando Basin and Transverse Ranges to help characterize the structure underlying this area. 249 gravity measurements were collected along the transect and to augment regional coverage near...

2001, Open-File Report 01-163
The August 17, 1999 Izmit (Turkey) earthquake (Mw=7.4) will be remembered as one of the largest earthquakes of recent times that affected a large urban environment (U.S. Geological Survey, 1999). This significant event was followed by many significant aftershocks and another main event (Mw=7.2) that occurred on November 12,...

Interpretive geologic cross sections for the Death Valley regional flow system and surrounding areas, Nevada and California
D. S. Sweetkind, R. P. Dickerson, R.J. Blakely, Paul Denning
2001, Miscellaneous Field Studies Map 2370
This report presents a network of 28 geologic cross sections that portray subsurface geologic relations within the Death Valley regional ground-water system, a ground-water basin that encompasses a 3? x 3? area (approximately 70,000 km2) in southern Nevada and eastern California. The cross sections transect that part of the southern...
Water quality in the upper Shoal Creek basin, southwestern Missouri, 1999-2000
John G. Schumacher
2001, Water-Resources Investigations Report 2001-4181
Results of a water-quality investigation of the upper Shoal Creek Basin in southwestern Missouri indicate that concentrations of total nitrite plus nitrate as nitrogen (NO2t+NO3t) in water samples from Shoal Creek were unusually large [mean of 2.90 mg/L (milligrams per liter), n (sample size)=60] compared to other Missouri streams (mean of 1.02...
Susceptibility index to surface contamination for the Little Cross Creek watershed, Cumberland County, North Carolina
M. J. Giorgino, Silvia Terziotti
2001, Water-Resources Investigations Report 2001-4143
An index of surface-water contamination potential was constructed for the Little Cross Creek Basin, a 9.7-square-mile, water-supply watershed in Cumberland County, North Carolina. The index was developed because previous water-quality investigations raised concerns regarding inputs of bacteria, suspended sediment, and phosphorus from nonpoint sources in the watershed. A geographic information...

2001, Circular 1196-A
In 1998, 175 metric tons (t) of refined gold was recovered by U.S. refiners from old and new scrap. The overall recycling rate was 29 percent when scrap consumption was compared with apparent domestic supply. Sources of old scrap includes discarded jewelry, dental materials, plating solutions, and electronic equipment. A...
