The WAIS (West Antarctic Ice Sheet) Divide deep ice core was recently completed to a total depth of 3405 m, ending ∼50 m above the bed. Investigation of the visual stratigraphy and grain characteristics indicates that the ice column at the drilling location is undisturbed by any large-scale overturning or...
Widespread gas hydrate instability on the upper U.S. Beaufort margin
Benjamin J. Phrampus, Matthew J. Hornbach, Carolyn D. Ruppel, Patrick E. Hart
2014, Journal of Geophysical Research B: Solid Earth (119) 8594-8609
The most climate-sensitive methane hydrate deposits occur on upper continental slopes at depths close to the minimum pressure and maximum temperature for gas hydrate stability. At these water depths, small perturbations in intermediate ocean water temperatures can lead to gas hydrate dissociation. The Arctic Ocean has experienced more dramatic warming...
U.S. Geological Survey unconventional petroleum systems research in south Mississippi: Observations on burial history and thermal maturity in the Cretaceous
Paul C. Hackley, Brett J. Valentine, Catherine B. Enomoto, James L. Coleman
2014, Mississippi Geological Society Bulletin (63) 9-15
Shale hydrocarbon ‘resource’ plays have revolutionized the United States energy mix over the last 5 years. These plays are diverse in lithology and age but share the common feature of occurring in ‘tight’ formations which require hydraulic (hydro-) fracturing for economic flow rates. In general, economic success requires an organic-rich reservoir with a...

Ieda Del’Arco Sanches, Carlos Roberto de Souza Filho, Raymond F. Kokaly
2014, ISPRS Journal of Photogrammetry and Remote Sensing (97) 111-122
This paper explores the use of spectral feature analysis to detect plant stress in visible/near infrared wavelengths. A time series of close range leaf and canopy reflectance data of two plant species grown in hydrocarbon-contaminated soil was acquired with a portable spectrometer. The ProSpecTIR-VS airborne imaging spectrometer was used to...

2014, Journal of Hydrology (519) 3010-3027
Organic matter (OM) is abundant in Fanno Creek, Oregon, USA, and has been tied to a variety of water-quality concerns, including periods of low dissolved oxygen downstream in the Tualatin River, Oregon. The key sources of OM in Fanno Creek and other Tualatin River tributaries have not been fully identified,...
The effects of spilled oil on coastal ecosystems: Lessons from the Exxon Valdez spill
James L. Bodkin, Daniel Esler, Stanley D. Rice, Craig O. Matkin, Brenda E. Ballachey, Brooke Maslo, Julie L. Lockwood
2014, Book chapter, Coastal conservation
Oil spilled from ships or other sources into the marine environment often occurs in close proximity to coastlines, and oil frequently accumulates in coastal habitats. As a consequence, a rich, albeit occasionally controversial, body of literature describes a broad range of effects of spilled oil across several habitats, communities,...
Shale: an overlooked option for US nuclear waste disposal
Christopher E. Neuzil
2014, Bulletin of the Atomic Scientists
Toss a dart at a map of the United States and, more often than not, it will land where shale can be found underground. A drab, relatively featureless sedimentary rock that historically attracted little interest, shale (as used here, the term includes clay and a range of clay-rich rocks) is...
Characterizing phosphorus dynamics in tile-drained agricultural fieldsof eastern Wisconsin
Allison Madison, Matthew Ruark, Todd D. Stuntebeck, Matthew J. Komiskey, Laura W. Good, Nancy Drummy, Eric Cooley
2014, Journal of Hydrology (519 A) 892-901
Artificial subsurface drainage provides an avenue for the rapid transfer of phosphorus (P) from agricultural fields to surface waters. This is of particular interest in eastern Wisconsin, where there is a concentrated population of dairy farms and high clay content soils prone to macropore development. Through collaboration with private landowners,...

Jose Javier Alvaro, Fouad Benziane, Robert Thomas, Gregory J. Walsh, Abdelaziz Yazidi
2014, Journal of African Earth Sciences (98) 19-33
In the last two decades, great progress has been made in the geochronological, chrono- and chemostratigraphic control of the Neoproterozoic and Cambrian from the Anti-Atlas Ranges and the Ouzellagh promontory (High Atlas). As a result, the Neoproterozoic is lithostratigraphically subdivided into: (i) the Lkest-Taghdout Group (broadly interpreted at c. 800–690 Ma)...

2014, Canadian Journal of Forest Research (45) 185-193
Northern peatlands represent a long-term net sink for atmospheric CO2, but these ecosystems can shift from net carbon (C) sinks to sources based on changing climate and environmental conditions. In particular, changes in water availability associated with climate control peatland vegetation and carbon uptake processes. We examined the influence of...
