Quantifying differences in the impact of variable chemistry on equilibrium uranium(VI) adsorption properties of aquifer sediments
Deborah L. Stoliker, Douglas B. Kent, John M. Zachara
2011, Environmental Science & Technology (45) 8733-8740
Uranium adsorption-desorption on sediment samples collected from the Hanford 300-Area, Richland, WA varied extensively over a range of field-relevant chemical conditions, complicating assessment of possible differences in equilibrium adsorption properties. Adsorption equilibrium was achieved in 500-1000 h although dissolved uranium concentrations increased over thousands of hours owing to changes in...
Constraints on the long‐period moment‐dip tradeoff for the Tohoku earthquake
Victor C. Tsai, Gavin P. Hayes, Zacharie Duputel
2011, Geophysical Research Letters (38)
Since the work of Kanamori and Given (1981), it has been recognized that shallow, pure dip‐slip earthquakes excite long‐period surface waves such that it is difficult to independently constrain the moment (M0) and the dip (δ) of the source mechanism, with only the product M0 sin(2δ) being well constrained. Because of this,...

Publicsupply use accounted for about 70 percent of the total water withdrawn. Other categories of use...
Prediction and assimilation of surf-zone processes using a Bayesian network: Part II: Inverse models
Nathaniel G. Plant, K. Todd Holland
2011, Coastal Engineering (58) 256-266
A Bayesian network model has been developed to simulate a relatively simple problem of wave propagation in the surf zone (detailed in Part I). Here, we demonstrate that this Bayesian model can provide both inverse modeling and data-assimilation solutions for predicting offshore wave heights and depth estimates given limited wave-height...
Probability of detecting perchlorate under natural conditions in deep groundwater in California and the Southwestern United States
Miranda S. Fram, Kenneth Belitz
2011, Environmental Science & Technology (45) 1271-1277
We use data from 1626 groundwater samples collected in California, primarily from public drinking water supply wells, to investigate the distribution of perchlorate in deep groundwater under natural conditions.

Prediction and assimilation of surf-zone processes using a Bayesian network: Part I: Forward models
Nathaniel G. Plant, K. Todd Holland
2011, Coastal Engineering (58) 119-130
Prediction of coastal processes, including waves, currents, and sediment transport, can be obtained from a variety of detailed geophysical-process models with many simulations showing significant skill. This capability supports a wide range of research and applied efforts that can benefit from accurate numerical predictions. However, the predictions are only as...
Water-quality requirements, tolerances, and preferences of pallid sturgeon Scaphirhynchus albus in the lower Missouri River
Dale W. Blevins
2011, Scientific Investigations Report 2011-5186
Although numerous studies have been completed on pallid sturgeon populations and behavior, few have addressed the potential for water-quality characteristics to limit recruitment and population success of pallid sturgeon. Literature on sturgeon and water-quality data indicates recruitment of pallid sturgeon may be limited by several water-quality characteristics of the lower...

James D. Austin, Howard L. Jelks, Bill Tate, Aria R. Johnson, Frank Jordan
2011, Conservation Genetics (12) 981-989
Imperiled Okaloosa darters (Etheostoma okaloosae) are small, benthic fish limited to six streams that flow into three bayous of Choctawhatchee Bay in northwest Florida, USA. We analyzed the complete mitochondrial cytochrome b gene and 10 nuclear microsatellite loci for 255 and 273 Okaloosa darters, respectively. Bayesian clustering analyses and AMOVA reflect congruent...

Lori A. Randall, Robert H. Diehl, Barry C. Wilson, Wylie C. Barrow, Clinton W. Jeske
2011, Journal of Wildlife Management (75) 1324-1329
To protect and restore wintering waterfowl habitat, managers require knowledge of routine wintering waterfowl movements and habitat use. During preliminary screening of Doppler weather radar data we observed biological movements consistent with routine foraging flights of wintering waterfowl known to occur near Lacassine National Wildlife Refuge (NWR), Louisiana. During the...

Estimating eruption temperature from thermal emission spectra of lava fountain activity in the Erta'Ale (Ethiopia) volcano lava lake: Implications for observing Io's volcanoes
Ashley G. Davies, Laszlo P. Keszthelyi, Alfred S. McEwen
2011, Geophysical Research Letters (38)
We have analysed high-spatial-resolution and high-temporal-resolution temperature measurements of the active lava lake at Erta'Ale volcano, Ethiopia, to derive requirements for measuring eruption temperatures at Io's volcanoes. Lava lakes are particularly attractive targets because they are persistent in activity and large, often with ongoing lava fountain activity that exposes lava...

2011, Open-File Report 2011-1272
Estuarine fish serve as an important prey base in the Greater Everglades ecosystem for key fauna such as wading birds, crocodiles, alligators, and piscivorous fishes. Human-made changes to freshwater flow across the Greater Everglades have resulted in less freshwater flow into the fringing estuaries and coasts. These changes in freshwater...
