Brookian structural plays in the National Petroleum Reserve, Alaska
Christopher J. Potter, Thomas E. Moore
2003, Open-File Report 2003-266
As part of the U.S. Geological Survey assessment of undiscovered oil and gas resources in the National Petroleum Reserve-Alaska (NPRA), two structural plays were assessed in thrust-faulted and folded Upper Cretaceous rocks of the Brookian megasequence. These are the Brookian Topset Structural Play and the Torok Structural Play, located in the Brooks Range foothills...
Selenium and sediment loads in storm runoff in Panoche Creek, California, February 1998
Charles R. Kratzer, Dina K. Saleh, Celia Zamora
2003, Water-Resources Investigations Report 2002-4286
Five to nine samples were collected per storm throughout the hydrograph of four storms in February 1998 from Panoche Creek at Interstate 5, California. The rainfall total of 10.40 inches for the month was greater than any other month during 1957 to 2000, and peak streamflows on February 3 and...
The Pu‘u ‘Ō‘ō-Kūpaianaha eruption of Kīlauea Volcano, Hawai‘i: The first 20 years
Christina C. Heliker, Donald A. Swanson, Taeko Jane Takahashi, editor(s)
2003, Professional Paper 1676
The Pu'u 'O'o-Kupaianaha eruption started on January 3, 1983. The ensuing 20-year period of nearly continuous eruption is the longest at Kilauea Volcano since the famous lava-lake activity of the 19th century. No rift-zone eruption in more than 600 years even comes close to matching the duration and volume of...
Evolution of trophic transmission in parasites: Why add intermediate hosts?
Marc Choisy, Sam P. Brown, Kevin D. Lafferty, Frederic Thomas
2003, American Naturalist (162) 172-181
Although multihost complex life cycles (CLCs) are common in several distantly related groups of parasites, their evolution remains poorly understood. In this article, we argue that under particular circumstances, adding a second host to a single-host life cycle is likely to enhance transmission (i.e., reaching the target host). For instance,...
Earth Observing-1 Extended Mission
Water Resources Division, U.S. Geological Survey
2003, Fact Sheet 032-03
From its beginning in November 2000, the NASA Earth Observing-1 (EO-1) mission demonstrated the feasibility and performance of a dozen innovative sensor, spacecraft, and operational technologies. The 1-year mission tested a variety of technologies, some of which may be included on the planned 2007 Landsat Data Continuity Mission. Onboard the...
The U.S. Geological Survey Land Remote Sensing Program
Water Resources Division, U.S. Geological Survey
2003, Fact Sheet 022-03
In 2002, the U. S. Geological Survey (USGS) launched a program to enhance the acquisition, preservation, and use of remotely sensed data for USGS science programs, as well as for those of cooperators and customers. Remotely sensed data are fundamental tools for studying the Earth's land surface, including coastal and...
Trends in suspended-sediment concentration at selected stream sites in Kansas, 1970–2002
James E. Putnam, Larry M. Pope
2003, Water-Resources Investigations Report 2003-4150
Knowledge of erosion, transport, and deposition of sediment relative to streams and impoundments is important to those involved directly or indirectly in the development and management of water resources. Monitoring the quantity of sediment in streams and impoundments is important because: (1) sediment may degrade the water quality of streams...
Methods of analysis by the U.S. Geological Survey National Water Quality Laboratory-Determination of gasoline oxygenates, selected degradates, and BTEX in water by heated purge and trap/gas chromatography/mass spectrometry
Donna L. Rose, Mark W. Sandstrom
2003, Water-Resources Investigations Report 2003-4079
A method for determination of the alkyl ethers u sed as gasoline oxygenates [ethyl tert-butyl ether (ETBE), methyl tert-butyl ether (MTBE), diisopropyl ether (DIPE), and tert-amyl methyl ether (TAME)], some of their main degradates [acetone, methyl acetate, tert-butyl alcohol (tBA), and tert-amyl alcohol (tAA)], and BTEX (benzene, toluene, ethylbenzene, and...
Hydrogeology and geochemistry of aquifers underlying the San Lorenzo and San Leandro areas of the East Bay Plain, Alameda County, California
John A. Izbicki, James W. Borchers, David A. Leighton, Justin T. Kulongoski, Latoya Fields, Devin L. Galloway, Robert L. Michel
2003, Water-Resources Investigations Report 2002-4259
The East Bay Plain, on the densely populated eastern shore of San Francisco Bay, contains an upper aquifer system to depths of 250 feet below land surface and an underlying lower aquifer system to depths of more than 650 feet. Injection and recovery of imported water has been proposed for...
Use of an intact core and stable-metal isotopes to examine leaching characteristics of a fluvial tailings deposit
James F. Ranville, Kathleen S. Smith, Paul J. Lamothe, Brian P. Jackson, Katherine Walton-Day
2003, Conference Paper, Proceedings of the Sixth International Conference on Acid Rock Drainage
The upper Arkansas River south of Leadville, Colorado, USA, contains deposits of fluvial tailings from historical mining operations in the Leadville area. These deposits are possible non-point sources of acid and metal contamination to surface- and ground-water systems. We used stable-metal isotopes to help ascertain metal retention and release mechanisms...
Arsenic in ground water: Geochemistry and occurrence
Alan H. Welch, Kenneth G. Stollenwerk, editor(s)
2003, Book
Interest in arsenic in ground water has greatly increased in the past decade because of the increased awareness of human health effects and the costs of avoidance or treatment of ground water supplies used for consumption. The goal of this book is to provide a description of the basic processes...
Channel response to tectonic forcing: field analysis of stream morphology and hydrology in the Mendocino triple junction region, northern California
Noah P. Snyder, Kelin X. Whipple, Gregory E. Tucker, D.J. Merritts
2003, Geomorphology (53) 97-127
An empirical calibration of the shear stress model for bedrock incision is presented, using field and hydrologic data from a series of small, coastal drainage basins near the Mendocino triple junction in northern California. Previous work comparing basins from the high uplift zone (HUZ, uplift rates around 4 mm/year) to ones in the low uplift zone (LUZ, ∼0.5...
Characterizing benthic substrates of Santa Monica Bay with seafloor photography and multibeam sonar imagery
Brian Andrews, Peter Dartnell, Henry Chezar
2003, Marine Environmental Research (56) 47-66
Seafloor photography from three cruises is combined with multibeam sonar imagery to characterize benthic substrates and associated fauna of Santa Monica Bay, California. The multibeam EM1000 imagery was collected in 1996. Two sampling cruises (in 1998 and 1999) provided photographs at 142 sites throughout the Bay; a final cruise (in...
Changing anthropogenic influence on the Santa Monica Bay watershed
M.A. Dojka, M. Yamaguchi, S.B. Weisberg, H.J. Lee
2003, Marine Environmental Research (56) 1-14
Santa Monica Bay is an open coastal embayment located directly seaward of Los Angeles, California. The Bay provides vital economic value through its water-dependent activities, such as swimming, diving, boating, and fishing. An increase from 100,000 residents in 1900 to 10 million in 2000 has imposed numerous environmental stressors on...

Predicting rare plant occurrence in Great Smoky Mountains National Park, USA
John R. Boetsch, Frank T. van Manen, Joseph D. Clark
2003, Natural Areas Journal (23) 229-237
We investigated the applicability of biometric habitat modeling to rare plant inventory and conservation by developing and field testing a geographically explicit model for Cardamine clematitis Shuttleworth ex A. Gray (mountain bittercress), an endemic plant of the southern Blue Ridge Mountains, USA. For each of 187 confirmed coordinates for C....
