2014, Estuaries and Coasts (37) 1107-1119
Sediment accretion was measured at four sites in varying stages of forest-to-marsh succession along a fresh-to-oligohaline gradient on the Waccamaw River and its tributary Turkey Creek (Coastal Plain watersheds, South Carolina) and the Savannah River (Piedmont watershed, South Carolina and Georgia). Sites included tidal freshwater forests, moderately salt-impacted forests at...
Environmental and physiological influences to isotopic ratios of N and protein status in a montane ungulate in winter
David D. Gustine, Perry S. Barboza, Layne G. Adams, Nathan B. Wolf
2014, PLoS ONE (9)
Winter severity can influence large herbivore populations through a reduction in maternal proteins available for reproduction. Nitrogen (N) isotopes in blood fractions can be used to track the use of body proteins in northern and montane ungulates. We studied 113 adult female caribou for 13 years throughout a series of...
Application of binomial-edited CPMG to shale characterization
Kathryn E. Washburn, Justin E. Birdwell
2014, Journal of Magnetic Resonance (246) 72-78
Unconventional shale resources may contain a significant amount of hydrogen in organic solids such as kerogen, but it is not possible to directly detect these solids with many NMR systems. Binomial-edited pulse sequences capitalize on magnetization transfer between solids, semi-solids, and liquids to provide an indirect method of detecting solid...

Nathan J. Wood, Jamie L. Ratliff, John Schelling, Craig S. Weaver
2014, Applied Geography (52) 191-203
Scenario-based, loss-estimation studies are useful for gauging potential societal impacts from earthquakes but can be challenging to undertake in areas with multiple scenarios and jurisdictions. We present a geospatial approach using various population data for comparing earthquake scenarios and jurisdictions to help emergency managers prioritize where to focus limited resources...

Linking multi-temporal satellite imagery to coastal wetland dynamics and bird distribution
Bradley A. Pickens, Sammy L. King
2014, Ecological Modelling (285) 1-12
Ecosystems are characterized by dynamic ecological processes, such as flooding and fires, but spatial models are often limited to a single measurement in time. The characterization of direct, fine-scale processes affecting animals is potentially valuable for management applications, but these are difficult to quantify over broad extents. Direct predictors are...
