2001, Fact Sheet 032-01
Our Nation faces the simultaneous challenges of increasing demand for energy, declining domestic production from existing oil and gas fields, and increasing expectations for environmental protection. The Energy Information Administration (2000) forecasts that worldwide energy consumption will increase 32 percent between 1999 and 2020 because of growth of the world...
Characterization of Northern California petroleum by stable carbon isotopes
Paul G. Lillis, Leslie B. Magoon, Richard G. Stanley, Robert J. McLaughlin, Augusta Warden
2001, Open-File Report 99-164
The purpose of this study is to characterize natural occurrences of petroleum at the surface and in the subsurface within northern California in order to define and map petroleum systems for U.S. Geological Survey energy resource assessments. Furthermore, the chemical characterization and mapping of natural petroleum occurrences could also be...
System and boundary conceptualization in ground-water flow simulation
T. E. Reilly
2001, Techniques of Water-Resources Investigations 03-B8
Ground-water models attempt to represent an actual ground-water system with a mathematical counterpart. The conceptualization of how and where water originates in the ground-water-flow system and how and where it leaves the system is critical to the development of an accurate model. The mathematical representation of these boundaries in the...

The Roseburg 30' x 60' Quadrangle covers the southeastern margin of the Oregon Coast Range and its tectonic boundary with Mesozoic terranes of the Klamath Mountains (see figures 1 and 2 in pamphlet, also shown on map sheet). The geologic framework of the Roseburg area was established by the pioneering...
The rainfall-triggered landslide and flash-flood disaster in northern Venezuela, December 1999
Matthew C. Larsen, Gerald F. Wieczorek, L.S. Eaton, Heriberto Torres-Sierra
2001, Conference Paper, Proceedings of the Seventh Federal Interagency Sedimentation Conference
Rainstorms in December 1999 induced thousands of landslides along the northern slopes of the Cordillera de la Costa mountain range principally in the state of Vargas, Venezuela. Rainfall accumulation of 293 millimeters during the first 2 weeks ofDecember was followed by an additional 911 millimeters of rainfall on December 14 through 16. The landslides and...

Intermittent feeding in a migratory omnivore: Digestion and body composition of American Black Duck during autumn
Perry S. Barboza, Dennis G. Jorde
2001, Physiological and Biochemical Zoology (74) 307-317
Birds fast intermittently during weather disturbances and migration. We tested responses of black duck to lost feeding days during autumn mass gain. Nine adult males were fed a pelleted diet (1.5% fat, 15.8% protein, and 18.3% neutral detergent fiber) and caged indoors during September and October (12 h light; 17°–24°C)...
Coastal-zone hazard maps and recommendations: Eastern Puerto Rico
David M. Bush, Bruce M. Richmond, William J. Neal
2001, Environmental Geosciences (8) 38-60
A series of coastal zone hazard maps cover the area impacted by Hurricane Hugo (1989) in eastern Puerto Rico. The mapping strategy was to develop a tool for quick visualization of multiple hazards for use by coastal planners, managers, property owners, and potential property owners. The Puerto Rico shoreline is...

Sediment-quality assessment of Franklin D. Roosevelt Lake and the upstream reach of the Columbia River, Washington, 1992
Gilbert Carl Bortleson, S.E. Cox, M.D. Munn, R.J. Schumaker, E. K. Block
2001, Water Supply Paper 2496
Elevated concentrations of trace elements were found in bed sediment of Lake Roosevelt and the Columbia River, its principal source of inflow. Trace-element concentrations in whole water samples did not exceed criteria for freshwater organisms. Bed sediments of Lake Roosevelt were analyzed for organic compounds associated with wood-pulp waste. Dioxins...

Geochemical results of a hydrothermally altered area at Baker Creek, Blaine County, Idaho
James A. Erdman, Falma J. Moye, Paul K. Theobald, Anne E. McCafferty, Richard K. Larsen
2001, Bulletin 2064-GG
The area immediately east of Baker Creek, Blaine County, Idaho, is underlain by a thick section of mafic to intermediate lava flows of the Eocene Challis Volcanic Group. Widespread propylitic alteration surrounds a zone of argillic alteration and an inner core of phyllic alteration. Silicified breccia is present along an east-trending...
Model coupling intraparticle diffusion/sorption, nonlinear sorption, and biodegradation processes
Hrissi K. Karapanagioti, Chris M. Gossard, Keith A. Strevett, Randall L. Kolar, David A. Sabatini
2001, Journal of Contaminant Hydrology (48) 1-21
Diffusion, sorption and biodegradation are key processes impacting the efficiency of natural attenuation. While each process has been studied individually, limited information exists on the kinetic coupling of these processes. In this paper, a model is presented that couples nonlinear and nonequilibrium sorption (intraparticle diffusion) with biodegradation kinetics. Initially, these...
