Estimated Ground-Water Withdrawals from the Death Valley Regional Flow System, Nevada and California, 1913-98
Michael T. Moreo, Keith J. Halford, Richard J. La Camera, Randell J. Laczniak
2003, Water-Resources Investigations Report 2003-4245
Ground-water withdrawals from 1913 through 1998 from the Death Valley regional flow system have been compiled to support a regional, three-dimensional, transient ground-water flow model. Withdrawal locations and depths of production intervals were estimated and associated errors were reported for 9,300 wells. Withdrawals were grouped into three categories: mining, public-supply,...

This report gives estimates of, and presents techniques for estimating, the magnitude of peak flows for streams in Kentucky for recurrence intervals of 2, 5, 10, 25, 50, 100, 200, and 500 years. A flowchart in this report guides the user to the appropriate estimates and (or) estimating techniques for...
The National Map: from geography to mapping and back again
John A. Kelmelis, Mark L. DeMulder, Charles E. Ogrosky, J. Nicholas Van Driel, Barbara J. Ryan
2003, Photogrammetric Engineering and Remote Sensing (69) 1109-1118
When the means of production for national base mapping were capital intensive, required large production facilities, and had ill-defined markets, Federal Government mapping agencies were the primary providers of the spatial data needed for economic development, environmental management, and national defense. With desktop geographic information systems now ubiquitous, source data...
Deformation of the 2002 Denali Fault earthquakes, mapped by Radarsat-1 interferometry
Zhong Lu, Tim Wright, Charles W. Wicks Jr.
2003, Eos, Transactions, American Geophysical Union (84) 425-431
The magnitude 7.9 earthquake that struck central Alaska on 3 November 2002 was the largest strike-slip earthquake in North America for more than 150 years. The earthquake ruptured about 340 km of the Denali Fault system with observed right-lateral offsets of up to 9 m [Eberhart-Phillips et al., 2003] (Figure...

Laurel G. Woodruff, John W. Attig, William F. Cannon, Suzanne W. Nicholson, Klaus Schulz
2003, Open-File Report 2003-353
In 1998 the U.S. Geological Survey (USGS) initiated a study to examine the natural regional environmental impact of sulfide mineralization exposed to episodic weathering and glaciation. The study focused on the Bend copper-gold massive sulfide deposit located in the Medford District of the Chequamegon National Forest in north central Wisconsin....
Texture, Carbonate Content, and Preliminary Maps of Surficial Sediments of the Flower Garden Banks Area, Northwestern Gulf of Mexico Outer Shelf
Kathryn M. Scanlon, Seth D. Ackerman, Jill E. Rozycki
2003, Open-File Report 2003-2
The purpose of this report is to release texture and carbonate content analyses of 107 seafloor sediments collected within and near the East and West Flower Garden Banks areas of the Sanctuary and to show relationships between these data and existing bathymetric data. The sediment data, in conjunction with previously...
External quality-assurance results for the National Atmospheric Deposition Program/National Trends Network, 1997-99
John D. Gordon, Natalie E. Latysh, Sandy J. Lindholm
2003, Water-Resources Investigations Report 2003-4027
Five external quality-assurance programs were operated by the U.S. Geological Survey for the National Atmospheric Deposition Program/ National Trends Network (NADP/NTN) during 1997 through 1999: the intersite-comparison program, the blind-audit program, the field- audit program, the interlaboratory-comparison program, and the collocated-sampler program. The intersite-comparison program assesses the accuracy of pH...
Correlates to survival of juvenile sea otters in Prince William Sound, Alaska, 1992-1993
Brenda E. Ballachey, James L. Bodkin, S. Howlin, A. M. Doroff, A.H. Rebar
2003, Canadian Journal of Zoology (81) 1494-1510
We estimated survival of sea otters (Enhydra lutris) for 1 year post weaning during 1992-1993 in Prince William Sound (PWS), location of the 1989 Exxon Valdez oil spill. We sampled 38 pups in eastern PWS (EPWS), an unoiled area occupied by sea otters for <15 years, and 33 pups from oiled western PWS (WPWS), occupied for >25 years. We compared survival between areas, sexes, and condition groups. We...
Evidence of change in a low-elevation forest bird community of Hawai'i since 1979
Michelle H. Reynolds, Richard J. Camp, Bonnie M. B. Nielson, James D. Jacobi
2003, Bird Conservation International (13) 175-187
We evaluated the abundance and distribution of low-elevation forest birds on windward Hawai'i Island during August 1993-February 1994, and present evidence of changes in the species composition of the forest bird community since 1979. Endemic Hawaiian birds occurred in native-dominated forests as low as 120 m elevation. Non-native species were...
GHASTLI — Determining physical properties of sediment containing natural and laboratory-formed gas hydrate
William J. Winters, William P. Dillon, Ingo A. Pecher, David H. Mason
Michael D. Max, editor(s)
2003, Book chapter, Natural gas hydrate in oceanic and permafrost environments
Gas-hydrate samples have been recovered at about 16 areas worldwide (Booth et al., 1996). However, gas hydrate is known to occur at about 50 locations on continental margins (Kvenvolden, 1993) and is certainly far more widespread so it may represent a potentially enormous energy resource (Kvenvolden, 1988). But adverse effects...
Introduction to physical properties and elasticity models
Jack Dvorkin, Michael B. Helgerud, William F. Waite, Stephen H. Kirby, Amos Nur
2003, Book chapter, Natural gas hydrate in oceanic and permafrost environments
Estimating the in situ methane hydrate volume from seismic surveys requires knowledge of the rock physics relations between wave speeds and elastic moduli in hydrate/sediment mixtures. The elastic moduli of hydrate/sediment mixtures depend on the elastic properties of the individual sedimentary particles and the manner in which they are arranged....
The U.S. Atlantic continental margin: The best-known gas hydrate locality
William P. Dillon, Michael D. Max
M.D. Max, editor(s)
2003, Book chapter, Natural gas hydrate: In oceanic and permafrost environments
One of the few attempts to date to map gas hydrate over a large area has been made on the Atlantic continental margin of the United States (Dillon et al., 1993, 1994, 1995). This work has resulted in the production of an extensive data base of seismic reflection lines including...
The use of traditional Hawaiian knowledge in the contemporary management of marine resources
Kelson K. Poepoe, Paul K. Bartram, Alan M. Friedlander
Nigel Haggan, Claire Brignall, Louisa E. Wood, editor(s)
2003, Fisheries Center Research Reports (11) 328-339
It is traditional for Hawaiians to "consult nature" so that fishing is practiced at times and places, and with gear that causes minimum disruption of natural biological and ecological processes. The Ho'olehua Hawaiian Homestead continues this tradition in and around Mo'omomi Bay on the northwest coast of the island of...
Effects of land subsidence in the Greater Houston Area
Devin L. Galloway, Laura S. Coplin, Steven E. Ingebritsen
D.E. Agthe, R.B. Billings, N. Buras, editor(s)

Reproductive maturation and senescence in the female brown bear
Charles C. Schwartz, Kim A. Keating, Harry V. Reynolds III, Victor G. Barnes Jr., Richard A. Sellers, J. E. Swenson, Sterling D. Miller, B. N. McLellan, Jeffrey A. Keay, Robert McCann, Michael Gibeau, Wayne F. Wakkinen, Richard D. Mace, Wayne Kasworm, Rodger Smith, Steven Herrero
2003, Ursus (14) 109-119
Changes in age-specific reproductive rates can have important implications for managing populations, but the number of female brown (grizzly) bears (Ursus arctos) observed in any one study is usually inadequate to quantify such patterns, especially for older females and in hunted areas. We examined patterns of reproductive maturation and senescence...
Modeling paleoclimates
Patrick J Bartlein, Steven W. Hostetler
2003, Developments in Quaternary Sciences 564-584
Paleoclimatic data and climate models play a complimentary role in understanding climate change. This chapter provides an overview of the process of climate-system modeling, presents the taxonomy of the models recently applied in the study of Quaternary climate change and variation, and discusses the development of climate modeling since the...
