2005, Conference Paper, Directions in strong motion instrumentation: Proceedings of the NATO SFP workshop on future directions in instrumentation for strong motion and engineering seismology, Kusadasi, Izmir, May 17-21, 2004
An integrated set of four borehole arrays and ten surface installations is installed in the city of San Francisco, California to measure the response of soft-soil deposits to strong earthquake ground motions. The borehole arrays extend through thick layers of soft water-saturated soils of Holocene age and older more consolidated...
Native fishes of the Sacramento-San Joaquin drainage, California: A history of decline
Larry R. Brown, Peter B. Moyle
2005, American Fisheries Society Symposium (45) 75-98
In this paper, we review information regarding the status of the native fishes of the combined Sacramento River and San Joaquin River drainages (hereinafter the "Sacramento-San Joaquin drainage") and the factors associated with their declines. The Sacramento-San Joaquin drainage is the center of fish evolution in California, giving rise to...

What can seismology say about hotspots?
Bruce R. Julian
Gillian R. Foulger, James H. Natland, Dean C. Presnall, Don L. Anderson, editor(s)
2005, Book chapter, Plates, plumes and paradigms
Seismological methods offer the highest-resolution views of the structure of the mantle. Since deep mantle plumes were proposed to explain melting anomalies (“hotspots”), increasingly powerful seismologic studies have sought to detect them, but so far without definitive success. This paper summarizes the relevant seismological methods and results for Earth scientists...
Environmental exposure modeling and monitoring of human pharmaceutical concentrations in the environment
D.J. Versteeg, A. C. Alder, V. L. Cunningham, D.W. Kolpin, R. Murray-Smith, T. Ternes
2005, Book chapter, Human pharmaceuticals: Assessing the impacts on aquatic ecosystems
Human pharmaceuticals are receiving increased attention as environmental contaminants. This is due to their biological activity and the number of monitoring programs focusing on analysis of these compounds in various environmental media and compartments. Risk assessments are needed to understand the implications of reported concentrations; a fundamental part of the...
Photogrammetric analysis of the Mars Global Surveyor mapping data
Jie Shan, Jong-suk Yoon, D. Scott Lee, Randolph L. Kirk, Gregory Neumann, Charles H. Acton
2005, Photogrammetric Engineering and Remote Sensing (1) 97-108
This paper studies the photogrammetric mapping properties and capabilities of the Mars Global Surveyor (MGS) mapping data. Starting from the raw MGS data, we decompress the MOC narrow angle images, extract, and calculate their exterior orientation from the SPICE kernels, and calculate the 3D coordinates of MOLA footprints from MOLA...

Evolution of a late Cenozoic supradetachment basin above a flat-on-flat detachment with a folded lateral ramp, SE Idaho
Alexander N. Steely, Susanne U. Janecke, Sean P. Long, Stephanie M. Carney, Robert Q. Oaks Jr., Victoria E. Langenheim, Paul K. Link
Joel L. Pederson, Carol M. Dehler, editor(s)
2005, Book chapter, Interior western United States
Uplift and exposure of the Bannock detachment system and the synextensional basin fill deposits of the Salt Lake Formation provide a unique exposure of the three-dimensional geometries of a low-angle normal fault system and the stratal architecture of the overlying supradetachment basin. Within this system, structural and stratigraphic analyses, outcrop...

Not only do “Volcanoes assail the senses …” (Decker and Decker, 1997, p. vii), but they also assail the environment when they erupt, terrifying and fascinating humankind for countless millennia. Volcanic processes and products – beneficial and hazardous – have profoundly impacted and continue to impact society (Chester, 1993, Chapter...
Identifying major sedimentary basins beneath the West Antarctic ice sheet from aeromagnetic data analysis

Dieter Karl Futterer, Detlef Damaske, Georg Kleinschmidt, Hubert Miller, Franz Tessensohn, editor(s)
2005, Book chapter, Antarctica: Contributions to global earth sciences
In the Ross Sea, large sedimentary basins reflect primarily the major extensional event associated with the Late Cretaceous breakup of Gondwana. Within the Interior Ross Embayment, no similar large basins have been identified to date. We have used aerogravity and Werner deconvolution methods applied to aeromagnetic data to map depth...

We compare recent magnetotelluric investigations of four large fault systems: (i) the actively deforming, ocean-continent interplate San Andreas Fault (SAF); (ii) the actively deforming, continent-continent interplate Dead Sea Transform (DST); (iii) the currently inactive, trench-linked intraplate West Fault (WF) in northern Chile; and (iv) the Waterberg...

Unsaturated zone flow processes
John R. Nimmo
2005, Book chapter, Encyclopedia of hydrological sciences, part 13, groundwater
Water flow in the unsaturated zone is greatly influenced by unsaturated hydrostatics (water content, energy, pressure, and retention) and by unsaturated hydrodynamics (diffuse flow and preferential flow). Important multiphase processes include the transport of gases, nonaqueous liquids, and solid particles. Numerous means are available for determination of unsaturated conditions and...
Sexual differentiation in the distribution potential of northern jaguars (Panthera onca)
Erin E. Boydston, Carlos A. Lopez Gonzalez
2005, Proceedings RMRS-P-36
We estimated the potential geographic distribution of jaguars in the southwestern United States and northwestern Mexico by modeling the jaguar ecological niche from occurrence records. We modeled separately the distribution of males and females, assuming records of females probably represented established home ranges while male records likely included dispersal movements....

2005, Open-File Report 2004-1064
A coastal vulnerability index (CVI) was used to map the relative vulnerability of the coast to future sea-level rise within Cape Hatteras National Seashore (CAHA) in North Carolina. The CVI ranks the following in terms of their physical contribution to sea-level rise-related coastal change: geomorphology, regional coastal slope, rate of...
The bear that never was

From campfire stories to sensational books detailing gory attacks, Alaska's bears have long been maligned as deadly marauders capable of acquiring a taste for human flesh. Tall tales make for good storytelling but force bad reputations on the bears. When myth is compared to fact, the three North American's leading...
