2014, GSA Field Guides (35) 129-160
The recent development of unconventional oil and natural gas resources in the United States builds upon many decades of research, which included resource assessment and the development of well completion and extraction technology. The Eastern Gas Shales Project, funded by the U.S. Department of Energy in the 1980s, investigated the...
Fine-grained linings of leveed channels facilitate runout of granular flows
B.P. Kokelaar, R. L. Graham, J.M.N.T. Gray, James W. Vallance
2014, Earth and Planetary Science Letters (385) 172-180
Catastrophic dense granular flows, such as occur in rock avalanches, debris flows and pyroclastic flows, move as fully shearing mixtures that have approximately 60 vol.% solids and tend to segregate to form coarse-grained fronts and leveed channels. Levees restrict spreading of unconfined flows and form as coarse particles that become...
Self-recognition in corals facilitates deep-sea habitat engineering
Sebastian J Hennige, Cheryl L. Morrison, Armin U. Form, Janina Buscher, Nicholas A. Kamenos, J. Murray Roberts
2014, Scientific Reports (4) 1-7
The ability of coral reefs to engineer complex three-dimensional habitats is central to their success and the rich biodiversity they support. In tropical reefs, encrusting coralline algae bind together substrates and dead coral framework to make continuous reef structures, but beyond the photic zone, the cold-water coral Lophelia pertusa also...
Evaluation of potential protective factors against metabolic syndrome in bottlenose dolphins:feeding and activity patterns of dolphins in Sarasota Bay, Florida
Randall S. Wells, Katherine A. McHugh, David C. Douglas, Steve Shippee, Elizabeth Berens McCabe, Nélio B. Barros, Goldie T. Phillips
2014, Frontiers in Endocrinology (4) 1-16
Free-ranging bottlenose dolphins (Tursiops truncatus) living in Sarasota Bay, Florida appear to have a lower risk of developing insulin resistance and metabolic syndrome compared to a group of dolphins managed under human care. Similar to humans, differences in diet and activity cycles between these groups may explain why Sarasota dolphins...

Laurel J. Lacher, Dale S. Turner, Bruce Gungle, Brooke M. Bushman, Holly E. Richter
2014, Water (6) 3495-3527
The San Pedro River originates in Sonora, Mexico, and flows north through Arizona, USA, to its confluence with the Gila River. The 92-km Upper San Pedro River is characterized by interrupted perennial flow, and serves as a vital wildlife corridor through this semiarid to arid region. Over the past century,...
Earthquake mechanism and seafloor deformation for tsunami generation
Eric L. Geist, David D. Oglesby
Michael Beer, Ioannis A. Kougioumtzoglou, Edoardo Patelli, Ivan Siu-Kui Au, editor(s)
2014, Book chapter, Encyclopedia of earthquake engineering
Tsunamis are generated in the ocean by rapidly displacing the entire water column over a significant area. The potential energy resulting from this disturbance is balanced with the kinetic energy of the waves during propagation. Only a handful of submarine geologic phenomena can generate tsunamis: large-magnitude earthquakes, large landslides, and...

Well log and 2D seismic data character of the Wilcox Group in south-central Louisiana
Catherine B. Enomoto
2014, Gulf Coast Association of Geological Societies Transactions (64) 105-118
Well logs and 2D seismic data were used to interpret the depth and morphology of potential Paleocene and lower Eocene Wilcox Group slope and basin-floor reservoirs in south-central Louisiana. These may occur in a poorly explored area previously estimated by the U.S. Geological Survey to contain a mean undiscovered conventional...
Age estimation of burbot using pectoral fin rays, brachiostegal rays, and otoliths
Zachary B. Klein, Marc M. Terrazas, Michael C. Quist
2014, Intermountain Journal of Sciences (20) 57-67
Throughout much of its native distribution, burbot (Lota lota) is a species of conservation concern. Understanding dynamic rate functions is critical for the effective management of sensitive burbot populations, which necessitates accurate and precise age estimates. Managing sensitive burbot populations requires an accurate and precise non-lethal alternative. In an effort...
Preliminary testing of flow-ecology hypotheses developed for the GCP LCC region
Shannon K. Brewer, Mary Davis
2014, Cooperator Science Series FWS/CSS-108-2014
The Ecological Limits of Hydrological Alteration (ELOHA) framework calls for the development of flow-ecology hypotheses to support protection of the flow regime from ecologically harmful alteration due to human activities. As part of a larger instream flow project for the Gulf Coast Prairie Landscape Conservation Cooperative (GCP LCC), regional flow-ecology...

Stephen M. Howard, Joshua J. Picotte, Michael Coan
2014, Conference Paper, The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, Volume XL-1,
In 2006, the Monitoring Trends in Burn Severity (MTBS) project began a cooperative effort between the US Forest Service (USFS) and the U.S.Geological Survey (USGS) to map and assess burn severity all large fires that have occurred in the United States since 1984. Using Landsat imagery, MTBS is mandated to...

Craig R. Ely, William J.L. Sladen, Heather M. Wilson, Susan E. Savage, Kristine M. Sowl, Bill Henry, Mike Schwitters, James Snowden
2014, Wildfowl (64) 132-147
North American Tundra Swans Cygnus c. columbianus are composed of two wellrecognised populations: an Eastern Population (EP) that breeds across northern Canada and north of the Brooks Range in Alaska, which migrates to the eastern seaboard of the United States, and a Western Population (WP) that breeds in coastal regions of Alaska south of the Brooks...
Multielevation calibration of frequency-domain electromagnetic data
Burke J. Minsley, M. Andy Kass, Greg Hodges, Bruce D. Smith
2014, Geophysics (79) E201-E216
Systematic calibration errors must be taken into account because they can substantially impact the accuracy of inverted subsurface resistivity models derived from frequency-domain electromagnetic data, resulting in potentially misleading interpretations. We have developed an approach that uses data acquired at multiple elevations over the same location to assess calibration errors....

Estuarine removal of glacial iron and implications for iron fluxes to the ocean
Andrew W. Schroth, John Crusius, Ian Hoyer, Robert Campbell
2014, Geophysical Research Letters (41) 3951-3958
While recent work demonstrates that glacial meltwater provides a substantial and relatively labile flux of the micronutrient iron to oceans, the role of high-latitude estuary environments as a potential sink of glacial iron is unknown. Here we present the first quantitative description of iron removal in a meltwater-dominated estuary. We...
Borehole radar interferometry revisited
Lanbo Liu, Chunguang Ma, John W. Lane Jr., Peter K. Joesten
2014, Conference Paper, Proceedings of the 15th International Conference on Ground Penetrating Radar
Single-hole, multi-offset borehole-radar reflection (SHMOR) is an effective technique for fracture detection. However, commercial radar system limitations hinder the acquisition of multi-offset reflection data in a single borehole. Transforming cross-hole transmission mode radar data to virtual single-hole, multi-offset reflection data using a wave interferometric virtual source (WIVS) approach has been...
