Assessment of source probabilities for potential tsunamis affecting the U.S. Atlantic coast
E.L. Geist, T. Parsons
2009, Marine Geology (264) 98-108
Estimating the likelihood of tsunamis occurring along the U.S. Atlantic coast critically depends on knowledge of tsunami source probability. We review available information on both earthquake and landslide probabilities from potential sources that could generate local and transoceanic tsunamis. Estimating source probability includes defining both size and recurrence distributions for...

Scenarios are possible future states of the world that represent alternative plausible conditions under different assumptions. Often, scenarios are developed in a context relevant to stakeholders involved in their applications since the evaluation of scenario outcomes and implications can enhance decision-making activities. This paper reviews the state-of-the-art of scenario development...
Selenium and trace element mobility affected by periodic displacement of stratification in the Great Salt Lake, Utah
K. Beisner, D. L. Naftz, W.P. Johnson, X. Diaz
2009, Science of the Total Environment (407) 5263-5273
The Great Salt Lake (GSL) is a unique ecosystem in which trace element activity cannot be characterized by standard geochemical parameters due to the high salinity. Movement of selenium and other trace elements present in the lake bed sediments of GSL may occur due to periodic stratification displacement events or...
Flood frequency analysis for nonstationary annual peak records in an urban drainage basin
G. Villarini, J. A. Smith, F. Serinaldi, J. Bales, P.D. Bates, W.F. Krajewski
2009, Advances in Water Resources (32) 1255-1266
Flood frequency analysis in urban watersheds is complicated by nonstationarities of annual peak records associated with land use change and evolving urban stormwater infrastructure. In this study, a framework for flood frequency analysis is developed based on the Generalized Additive Models for Location, Scale and Shape parameters (GAMLSS), a tool...
Paragneiss zircon geochronology and trace element geochemistry, North Qaidam HP/UHP terrane, western China
C.G. Mattinson, J. L. Wooden, J.X. Zhang, D.K. Bird
2009, Journal of Asian Earth Sciences (35) 298-309
In the southeastern part of the North Qaidam terrane, near Dulan, paragneiss hosts minor peridotite and UHP eclogite. Zircon geochronology and trace element geochemistry of three paragneiss samples (located within a ???3 km transect) indicates that eclogite-facies metamorphism resulted in variable degrees of zircon growth and recrystallization in the three...
Timing of occurrence of large submarine landslides on the Atlantic Ocean margin
H.J. Lee
2009, Marine Geology (264) 53-64
Submarine landslides are distributed unevenly both in space and time. Spatially, they occur most commonly in fjords, active river deltas, submarine canyon-fan systems, the open continental slope and on the flanks of oceanic volcanic islands. Temporally, they are influenced by the size, location, and sedimentology of migrating depocenters, changes in...
Spatial and temporal spawning dynamics of native westslope cutthroat trout, Oncorhynchus clarkii lewisi, introduced rainbow trout, Oncorhynchus mykiss, and their hybrids
C.C. Muhlfeld, T.E. McMahon, D. Belcer, J. L. Kershner
2009, Canadian Journal of Fisheries and Aquatic Sciences (66) 1153-1168
We used radiotelemetry to assess spatial and temporal spawning distributions of native westslope cutthroat trout (Oncorhynchus clarkii lewisi; WCT), introduced rainbow trout (Oncorhynchus mykiss; RBT), and their hybrids in the upper Flathead River system, Montana (USA) and British Columbia (Canada), from 2000 to 2007. Radio-tagged trout (N = 125) moved...

James E. Vogelmann, Brian L. Tolk, Zhiliang Zhu
2009, Remote Sensing of Environment (113) 1739-1748
Landsat time series data sets were acquired for the Santa Fe National Forest in New Mexico. This area includes the San Pedro Parks Wilderness area, which was designated as an official wilderness in 1964. Eight autumnal Landsat Thematic Mapper (TM) scenes acquired from 1988 to 2006 were analyzed to determine...
Absolute stellar photometry on moderate-resolution FPA images
T.C. Stone
2009, Metrologia (46)
An extensive database of star (and Moon) images has been collected by the ground-based RObotic Lunar Observatory (ROLO) as part of the US Geological Survey program for lunar calibration. The stellar data are used to derive nightly atmospheric corrections for the observations from extinction measurements, and absolute calibration of the...
Age, differential growth and mortality rates in unexploited populations of Florida gar, an apex predator in the Florida Everglades
D.J. Murie, D.C. Parkyn, L.G. Nico, J.J. Herod, W.F. Loftus
2009, Fisheries Management and Ecology (16) 315-322
Florida gar, Lepisosteus platyrhincus DeKay, were sampled in two canal systems in south Florida during 2000-2001 to estimate age, growth and mortality as part of the Everglades ecosystem-restoration effort. Tamiami (C-4) and L-31W canal systems had direct connections to natural wetlands of the Everglades and harboured large Florida gar populations....
Process recognition in multi-element soil and stream-sediment geochemical data
E.C. Grunsky, L.J. Drew, D. M. Sutphin
2009, Applied Geochemistry (24) 1602-1616
Stream-sediment and soil geochemical data from the Upper and Lower Coastal Plains of South Carolina (USA) were studied to determine relationships between soils and stream sediments. From multi-element associations, characteristic compositions were determined for both media. Primary associations of elements reflect mineralogy, including heavy minerals, carbonates and clays, and the...
Osprey: Worldwide sentinel species for assessing and monitoring environmental contamination in rivers, lakes, reservoirs, and estuaries
Robert A. Grove, Charles J. Henny, James L. Kaiser
2009, Journal of Toxicology and Environmental Health, Part B: Critical Reviews (12) 25-44
In the United States, many fish and wildlife species have been used nationwide to monitor environmental contaminant exposure and effects, including carcasses of the bald eagle (Haliaeetus leucocephalus), the only top avian predator regularly used in the past. Unfortunately, bald eagles are sensitive to investigator intrusion at the nest. Thus,...
Wide-area estimates of saltcedar (Tamarix spp.) evapotranspiration on the lower Colorado River measured by heat balance and remote sensing methods
Pamela L. Nagler, Kiyomi Morino, Kamel Didan, J. Erker, John Osterberg, Kevin R. Hultine, Edward P. Glenn
2009, Ecohydrology (2) 18-33
In many places along the lower Colorado River, saltcedar (Tamarix spp) has replaced the native shrubs and trees, including arrowweed, mesquite, cottonwood and willows. Some have advocated that by removing saltcedar, we could save water and create environments more favourable to these native species. To test these assumptions we compared sap...
Mapping and monitoring Mt. Graham Red Squirrel habitat with GIS and thematic mapper imagery
James R. Hatten, John L. Koprowski
H. Reed Sanderson, John L. Koprowski, editor(s)
2009, Book chapter, The Last Refuge of the Mt. Graham Red Squirrel
To estimate the Mt. Graham red squirrel (MGRS) population, personnel visit a proportion of middens each year to determine their occupancy (Snow in this vol.). The method results in very tight confidence intervals (high precision), but the accuracy of the population estimate is dependent upon knowing where all the middens...
A Miocene to Pleistocene climate and elevation record of the Sierra Nevada (California)
A. Mulch, Andrei M. Sarna-Wojcicki, M. E. Perkins, C. P. Chamberlain
2009, PNAS (105) 6819-6824
Orographic precipitation of Pacific-sourced moisture creates a rain shadow across the central part of the Sierra Nevada (California) that contrasts with the southern part of the range, where seasonal monsoonal precipitation sourced to the south obscures this rain shadow effect. Orographic rainout systematically lowers the hydrogen isotope composition of precipitation...

Selenium Recycling in the United States in 2004
Micheal W. George, Lorie A. Wagner
2009, Circular 1196-T
The vast majority of selenium consumption in the United States is in dissipative uses, such as alloys, animal feeds, fertilizers, glass decolorizer, and pigments. The nondissipative use as a photoreceptor for xerographic copiers is declining. As a result of a lack of a substantial supply of selenium-containing scrap, there are...
