2003, Journal of Contaminant Hydrology (62-63) 731-750
This paper presents several different conceptual models of the Large Hydraulic Gradient (LHG) region north of Yucca Mountain and describes the impact of those models on groundwater flow near the potential high-level repository site. The results are based on a numerical model of site-scale saturated zone beneath Yucca Mountain. This model is used for performance assessment predictions of radionuclide transport...
Effects of spectrometer band pass, sampling, and signal‐to‐noise ratio on spectral identification using the Tetracorder algorithm
Gregg A. Swayze, Roger N. Clark, Alexander F.H. Goetz, Thomas G. Chrien, Noel S. Gorelick
2003, Journal of Geophysical Research: Planets (108) 1-30
[1] Estimates of spectrometer band pass, sampling interval, and signal‐to‐noise ratio required for identification of pure minerals and plants were derived using reflectance spectra convolved to AVIRIS, HYDICE, MIVIS, VIMS, and other imaging spectrometers. For each spectral simulation, various levels of random noise were added to the reflectance spectra after...
Numerical simulation of tsunami generation by pryoclastic flow at Aniakchak Volcano, Alaska
C. F. Waythomas, P. Watts
2003, Geophysical Research Letters (30)
Pyroclastic flows entering the sea are plausible mechanisms for tsunami generation at volcanic island arcs worldwide. We evaluate tsunami generation by pyroclastic flow using an example from Aniakchak volcano in Alaska where evidence for tsunami inundation coincident with a major, caldera-forming eruption of the volcano ca. 3.5 ka has been...
Surface complexation and precipitate geometry for aqueous Zn(II) sorption on ferrihydrite: II. XANES analysis and simulation
G.A. Waychunas, C. C. Fuller, J.A. Davis, J.J. Rehr
2003, Geochimica et Cosmochimica Acta (67) 1031-1043
X-ray absorption near-edge spectroscopy (XANES) analysis of sorption complexes has the advantages of high sensitivity (10- to 20-fold greater than extended X-ray absorption fine structure [EXAFS] analysis) and relative ease and speed of data collection (because of the short k-space range). It is thus a potentially powerful tool for characterization...
Benthic sulfate reduction along the Chesapeake Bay central channel. II. Temporal controls
M. C. Marvin-DiPasquale, W.R. Boynton, D.G. Capone
2003, Marine Ecology Progress Series (260) 55-70
Seasonal and interannual controls of benthic sulfate reduction (SR) were examined at 3 sites (upper [UB], mid- [MB] and lower [LB] bay) along the Chesapeake Bay central channel, from early spring through fall, for 6 yr (1989 to 1994). The combined influences of temperature, sulfate, organic loading and bioturbation affected...

Timing and nature of tertiary plutonism and extension in the Grouse Creek Mountains, Utah
A.E. Egger, T.A. Dumitru, E. L. Miller, C.F.I. Savage, J. L. Wooden
2003, International Geology Review (45) 497-532
The Grouse Creek-Albion-Raft River metamorphic core complex in northwestern Utah and southern Idaho is characterized by several Tertiary plutons with a range of ages and crosscutting relations that help constrain the timing of extensional deformation. In the Grouse Creek Mountains, at least three distinct, superimposed, extension-related Tertiary deformational events are bracketed by intrusive rocks, followed by a fourth event: motion on range-bounding faults. The Emigrant Pass plutonic complex...
The slow advance of a calving glacier: Hubbard Glacier, Alaska, U.S.A
D.C. Trabant, R. M. Krimmel, K.A. Echelmeyer, S.L. Zirnheld, D.H. Elsberg
2003, Annals of Glaciology (36) 45-50
Hubbard Glacier is the largest tidewater glacier in North America. In contrast to most glaciers in Alaska and northwestern Canada, Hubbard Glacier thickened and advanced during the 20th century. This atypical behavior is an important example of how insensitive to climate a glacier can become during parts of the calving...
US Atlantic coast striped bass: Issues with a recovered population
K.J. Hartman, F.J. Margraf
2003, Fisheries Management and Ecology (10) 309-312
Striped bass, Morone saxatilis (Walbaum), is an anadromous species naturally occurring along the US Atlantic coast, which historically supported valuable commercial and recreational fisheries. In response to a near order-of-magnitude decline in landings, the Atlantic States Marine Fisheries Commission enacted a management plan in 1981 protecting fish until they could...
Catchability of Walleyes to Fyke Netting and Electrofishing in Northern Wisconsin Lakes
M.W. Rogers, M.J. Hansen, T.D. Beard Jr.
2003, North American Journal of Fisheries Management (23) 1193-1206
We quantified relationships between both fyke-net catch rates (catch/net-night) and electrofishing catch rates (catch/mi) and population densities (number/acre) of walleye Sander vitreus (formerly Stizostedion vitreum) for adult population estimates and total population estimates to determine whether catchability was density dependent. Fyke-net catch rates were modeled as a nonlinear function of...

Gas bubble disease in resident fish below Grand Coulee Dam: final report of research
J.W. Beeman, D.A. Venditti, R.G. Morris, D.M. Gadomski, B.J. Adams, S.J. Vanderkooi, T.C. Robinson, A.G. Maule
2003, Report
Fish kills have occurred in the reservoir below Grand Coulee Dam possibly due to total dissolved gas supersaturation (TDGS), which occurs when water cascades over a dam or waterfall. The highest TDGS below Grand Coulee Dam has occurred after spilling water via the outlet tubes, though TDGS from upstream sources...
Effects of prairie fragmentation on the nest success of breeding birds in the midcontinental United States

2003, Conservation Biology (17) 587-594
Grassland fragmentation and habitat loss are hypothesized to be contributing to widespread grassland bird declines in North America due to the adverse effects of fragmentation on breeding bird abundance and reproductive success. To assess the effects of fragmentation on the reproductive success of grassland birds, we measured rates of nest...

Variations in flow and transport in thick desert vadose zones in response to paleoclimatic forcing (0-90 kyr): Field measurements, modeling, and uncertainties

2003, Water Resources Research (39)
An understanding of unsaturated flow and potential recharge in interdrainage semiarid and arid regions is critical for quantification of water resources and contaminant transport. We evaluated system response to paleoclimatic forcing using water potential and Cl profiles and modeling of nonisothermal liquid and vapor flow and Cl transport at semiarid...

2003, Environmental Science & Technology (37) 4083-4090
Recent U.S. government action to lower the maximum concentration levels (MCL) of total arsenic (As) (10 ppb) in drinking water has raised serious concerns about the agricultural use of As-containing biosolids such as poultry litter (PL). In this study, solid-state chemical speciation, desorbability, and total levels of...

Primary geologic and geomorphic processes that formed valley-bottom and channel features downstream from the Pelton-Round Butte dam complex are inferred from a canyon-long analysis of feature morphology, composition, location, and spatial distribution. Major controls on valley-bottom morphology are regional tectonics, large landslides, and outsized floods (floods with return periods greater...
