Tsunami Preparedness Along the U.S. West Coast (video)
Kurt Loeffler, Justine Gesell
2010, General Information Product 105
Tsunamis are a constant threat to the coasts of our world. Although tsunamis are infrequent along the West coast of the United States, it is possible and necessary to prepare for potential tsunami hazards to minimize loss of life and property. Community awareness programs are important, as they strive to...

James S. Kuwabara, Brent R. Topping, James L. Carter, Francis Parchaso, Jason M. Cameron, Jessica R. Asbill, Steven V. Fend, John H. Duff, Anita C. Engelstad
2010, Open-File Report 2010-1062
Four sampling trips were coordinated after planned levee breaches that hydrologically reconnected both Upper Klamath Lake and Agency Lake, Oregon, to adjacent wetlands. Sets of nonmetallic pore-water profilers were deployed during these trips in November 2007, June 2008, May 2009, and July 2009. Deployments temporally spanned the annual cyanophyte bloom...

Tamara Ivahnenko, Jennifer L. Flynn
2010, Scientific Investigations Report 2010-5002
The future health and economic welfare of the people and environment of Colorado depend on a continuous supply of fresh water. Detailed, comprehensive information on the use of water from Colorado's diverse surface-water and groundwater resources is important to water managers and planners by providing information they need to quantify...
Coastwide Reference Monitoring System (CRMS)
Gregory D. Steyer
2010, Fact Sheet 2010-3018
In 1990, the U.S. Congress enacted the Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) in response to growing awareness of a land loss crisis in Louisiana. Projects funded by CWPPRA require monitoring and evaluation of project effectiveness, and there is also a need to assess the cumulative effects of...

Arthur Frankel, Stephen Harmsen, Charles Mueller, Eric Calais, Jennifer Haase
2010, Open-File Report 2010-1067
In response to the urgent need for earthquake-hazard information after the tragic disaster caused by the moment magnitude (M) 7.0 January 12, 2010, earthquake, we have constructed initial probabilistic seismic hazard maps for Haiti. These maps are based on the current information we have on fault slip rates and historical...

Lara M. Hinderstein, John C.A. Marr, Felix A. Martinez, Michael J. Dowgiallo, Richard L. Puglise, R. L. Pyle, David G. Zawada, R. Appeldoorn
2010, Coral Reefs (29) 247-251
Mesophotic coral ecosystems (MCEs) are characterized by the presence of light-dependent corals and associated communities that are typically found at depths ranging from 30 to 40 m and extending to over 150 m in tropical and subtropical regions. The dominant communities providing structural habitat in the mesophotic zone can be comprised of...
Dissolution-reprecipitation of igneous zircon in mid-ocean ridge gabbro, Atlantis Bank, Southwest Indian Ridge
J. Schwartz, Barbara E John, Michael J. Cheadle, Joseph L. Wooden, F. Mazdab, Susan Swapp, Craig B. Grimes
2010, Chemical Geology (274)-68
Zircons recovered from oceanic gabbro exposed on Atlantis Bank, Southwest Indian Ridge, typically display oscillatory and sector zoning consistent with igneous crystallization from mafic magmas. In one rock (of twenty investigated), weak-oscillatory-zonation patterns are overprinted by secondary textural features characterized by mottled, convoluted and wavy internal zonation patterns that are...
Ferromanganese crusts as archives of deep water Cd isotope compositions
T. J. Horner, M. Schonbachler, M. Rehkämper, S.G. Nielsen, H. Williams, A. N. Halliday, Z. George Xue, James R. Hein
2010, Geochemistry, Geophysics, Geosystems (11)
The geochemistry of Cd in seawater has attracted significant attention owing to the nutrient-like properties of this element. Recent culturing studies have demonstrated that Cd is a biologically important trace metal that plays a role in the sequestration of inorganic carbon. This conclusion is supported by recent isotope data for...
Multiple phases of basin formation along the Stateline fault system in the Pahrump and Mesquite Valleys, Nevada and California
Daniel S. Scheirer, Donald S. Sweetkind, John J. Miller
2010, Geosphere (6) 93-129
Two phases of deformation are needed to describe the Cenozoic tectonic evolution of the Pahrump and Mesquite basins in the southern Great Basin and eastern Mojave Desert, United States. By interpreting seismic reflection and gravity observations along with bedrock and surficial mapping, we infer an extensional phase of basin formation...
Reconnaissance geochronology of tuffs in the Miocene Barstow Formation: implications for basin evolution and tectonics in the central Mojave Desert
D. M. Miller, S.R. Leslie, John W. Hillhouse, J. L. Wooden, J.A. Vazquez, R. E. Reynolds
2010, Book, Overboard in the Mojave: 20 million years of lakes and wetlands
Early to middle Miocene lacustrine strata of the Barstow Formation are well dated in just a few places, limiting our ability to infer basin evolution and regional tectonics. At the type section in the Mud Hills, previous studies have shown that the lacustrine interval of the Barstow Formation is...

Bibek Sharma, Reynaldo Patino
2010, Chemosphere (79) 499-505
To assess interaction effects between cadmium (Cd, a putative xenoestrogen) and estradiol-17beta (E(2)) on sex differentiation and metamorphosis, Xenopus laevis were exposed to solvent-control (0.005% ethanol), Cd (10microgL(-1)), E(2) (1microgL(-1)), or Cd and E(2) (Cd+E(2)) in FETAX medium from fertilization to 75d postfertilization. Each treatment was applied to four aquaria,...
Reply to “Comment on ‘Is There a Basis for Preferring Characteristic Earthquakes over a Gutenberg–Richter Distribution in Probabilistic Earthquake Forecasting?’ by Tom Parsons and Eric L. Geist” by Jens-Uwe Klügel
Thomas E. Parsons, Eric L. Geist
2010, Bulletin of the Seismological Society of America (100) 898-899
The focus of Parsons and Geist (2009) was to test whether the key observational data used in earthquake forecasting necessitate a characteristic earthquake rupture model. The point of our article was not to suggest that a specific form of the Gutenberg–Richter earthquake distribution is a perfect representation of reality. The...
Organic petrology of subbituminous carbonaceous shale samples from Chalāw, Kabul Province, Afghanistan: Considerations for paleoenvironment and energy resource potential
Paul C. Hackley, John Sanfilipo, Gul Pacha Azizi, Philip A. Davis, Scott W. Starratt
2010, International Journal of Coal Geology (81) 269-280
Neogene (?) subbituminous carbonaceous shale deposits from Chalāw, Afghanistan, were investigated through organic petrology techniques and standard coal analyses to determine paleoenvironment and potential for resource utilization. The Chalāw deposit, approximately 30 km southeast of Kabul, currently is exploited for brick making and domestic heating and cooking. Three multiple-bench channel...

Julie V. Bednarski, Howard S. Ginsberg, Elizabeth M. Jakob
2010, Biological Invasions (12) 905-912
There are numerous reports of spiders that have become established outside of their native ranges, but few studies examine their impact on native spiders. We examined the effect of the European hammock spider Linyphia triangularis (Araneae, Linyphiidae) on the native bowl-and-doily spider Frontinella communis (Araneae, Linyphiidae)...
