2005, International Journal of Coal Geology (63) 205-227
With pending regulation of mercury emissions in United States power plants, its control at every step of the combustion process is important. An understanding of the amount of mercury in coal at the mine is the first step in this process. The Springfield coal (Middle Pennsylvanian) is one of the...
Demographics of an ornate box turtle population experiencing minimal human-induced disturbances
S. J. Converse, J. B. Iverson, J. A. Savidge
2005, Ecological Applications (15) 2171-2179
Human-induced disturbances may threaten the viability of many turtle populations, including populations of North American box turtles. Evaluation of the potential impacts of these disturbances can be aided by long-term studies of populations subject to minimal human activity. In such a population of ornate box turtles (Terrapene ornata ornata) in...

M. Stearns, J.A. Tindall, G. Cronin, M.J. Friedel, E. Bergquist
2005, Water, Air, & Soil Pollution (168) 33-57
Coal-bed methane (CBM) co-produced discharge waters in the Powder River Basin of Wyoming, resulting from extraction of methane from coal seams, have become a priority for chemical, hydrological and biological research during the last few years. Soil and vegetation samples were taken from affected and reference sites (upland elevations...

Kevin L. Pangle, Trent M. Sutton, Ronald E. Kinnunen, Michael H. Hoff
2005, Journal of Great Lakes Research (31) 360-366
Juvenile lake herring Coregonus artedi were exposed to rapid cooling events during two laboratory experiments to determine the effects of body size, physiological condition, and lipid content on survival. The first experiment was conducted at the onset of winter, exposing small (50 to 85 mm) and large (85 to 129 mm) fish...

An efficient algorithm for double-difference tomography and location in heterogeneous media, with an application to the Kilauea volcano
V. Monteiller, J.-L. Got, J. Virieux, P. Okubo
2005, Journal of Geophysical Research B: Solid Earth (110) 1-22
Improving our understanding of crustal processes requires a better knowledge of the geometry and the position of geological bodies. In this study we have designed a method based upon double-difference relocation and tomography to image, as accurately as possible, a heterogeneous medium containing seismogenic objects. Our approach consisted not only...
Complex channel responses to changes in stream flow and sediment supply on the lower Duchesne River, Utah
D. Gaeuman, J. C. Schmidt, P.R. Wilcock
2005, Geomorphology (64) 185-206
Channel responses to flow depletions in the lower Duchesne River over the past 100 years have been highly complex and variable in space and time. In general, sand-bed reaches adjusted to all perturbations with bed-level changes, whereas the gravel-bed reaches adjusted primarily through width changes. Gravel-bed reaches aggraded only when...

2005, Analytica Chimica Acta (549) 104-116
Polycyclic aromatic hydrocarbons (PAH) are recognized as environmentally relevant for their potential adverse effects on human and ecosystem health. This paper describes a method to determine the distribution of PAH and alkylated homolog groups in sediment samples. Pressurized liquid extraction (PLE), coupled with solid-phase extraction (SPE) cleanup, was developed to...
Magmatic unrest beneath Mammoth Mountain, California
D.P. Hill, S. Prejean
2005, Journal of Volcanology and Geothermal Research (146) 257-283
Mammoth Mountain, which stands on the southwest rim of Long Valley caldera in eastern California, last erupted ∼57,000 years BP. Episodic volcanic unrest detected beneath the mountain since late 1979, however, emphasizes that the underlying volcanic system is still active and capable of producing future volcanic eruptions. The unrest symptoms...

2005, Conference Paper, Genetic aspects of viability in small wolf populations with special emphasis on the Scandinavian wolf population
Wolf (Canis lupus) populations tend to be resilient and to persist for long periods, and several characteristics contribute to their resilience and persistence: (1) age of first reproduction (2-3 years), (2) high annual litter size (mean = 6), (3) low dispersal age (1-3 years), and (4) long potential dispersal distance...
Inhibition of calcite precipitation by natural organic material: Kinetics, mechanism, and thermodynamics
Y.-P. Lin, P.C. Singer, G. R. Aiken
2005, Environmental Science & Technology (39) 6420-6428
The inhibition of calcite precipitation by natural organic material (NOM) in solutions seeded with calcite was investigated using a pH-stat system. Experiments were carried out using three NOMs with different physical/chemical properties. For each of the materials, inhibition was found to be more effective at lower carbonate/calcium ratios and lower...

Long-term analysis of survival, fertility, and population growth rate of black bears in North Carolina
L.L. Brongo, M.S. Mitchell, J.B. Grand
2005, Journal of Mammalogy (86) 1029-1035
We estimated survival, fertility, and realized and asymptotic population growth rates from 1981 to 2002 for a protected population of black bears (Ursus americanus) in the southern Appalachian Mountains. We used Akaike's information criterion to assess the time interval for averaging observations that was best for estimating vital rates for...

L.F. Robinson, J.F. Adkins, L.D. Keigwin, J. Southon, D. P. Fernandez, S.-L. Wang, D.S. Scheirer
2005, Science (310) 1469-1473
We present a detailed history of glacial to Holocene radiocarbon in the deep western North Atlantic from deep-sea corals and paired benthic-planktonic foraminifera. The deglaciation is marked by switches between radiocarbon-enriched and -depleted waters, leading to large radiocarbon gradients in the water column. These changes played an important role in...

The Gulf of Maine Coastal Current (GMCC), which extends from southern Nova Scotia to Cape Cod Massachusetts, was investigated from 1998 to 2001 by means of extensive hydrographic surveys, current meter moorings, tracked drifters, and satellite-derived thermal imagery. The study focused on two principal branches of the GMCC, the Eastern...
Controlling for anthropogenically induced atmospheric variation in stable carbon isotope studies
E.S. Long, R.A. Sweitzer, Duane R. Diefenbach, M. Ben-David
2005, Oecologia (146) 148-156
Increased use of stable isotope analysis to examine food-web dynamics, migration, transfer of nutrients, and behavior will likely result in expansion of stable isotope studies investigating human-induced global changes. Recent elevation of atmospheric CO2 concentration, related primarily to fossil fuel combustion, has reduced atmospheric CO2 ??13C (13C/12C), and this change...
