Myung Woong Lee, Timothy S. Collett
2011, Book, Proceedings of the 7th International Conference on Gas Hydrates
High quality logging-while-drilling (LWD) well logs were acquired in seven wells drilled during the Gulf of Mexico Gas Hydrate Joint Industry Project Leg II in the spring of 2009. These data help to identify three distinct types of gas hydrate reservoirs: isotropic reservoirs in sands, vertical fractured reservoirs in shale,...

2011, Conference Paper, Proceedings of the 7th international conference on gas hydrates (ICGH 2011)
Gas hydrate was recovered from the Alaskan Beaufort Sea slope north of Camden Bay in August 2010 during a U.S. Coast Guard Cutter Healy expedition (USCG cruise ID HLY1002) under the direction of the U.S. Geological Survey (USGS). Interpretation of multichannel seismic (MCS) reflection data collected in 1977 by the...
Developing seismogenic source models based on geologic fault data
Kathleen M. Haller, Roberto Basili
2011, Seismological Research Letters (82) 519-525
Calculating seismic hazard usually requires input that includes seismicity associated with known faults, historical earthquake catalogs, geodesy, and models of ground shaking. This paper will address the input generally derived from geologic studies that augment the short historical catalog to predict ground shaking at time scales of tens, hundreds, or...

Miguel L. Villarreal, Laura M. Norman, Robert H. Webb, Diane E. Boyer, Raymond M. Turner
2011, Conference Paper, Proceedings of MULTITEMP 2011, 6th International Workshop on the Analysis of Multitemporal Remote Sensing Images
A significant amount of research conducted in the Sonoran Desert of North America has documented, both anecdotally and empirically, major vegetation changes over the past century due to human land use activities. However, many studies lack coincidental landscape-scale data characterizing the spatial and temporal manifestation of these changes. Vegetation changes...

2011, American Fisheries Society Symposium (77) 335-347
Anthropogenic alterations to Iowa’s landscape have greatly altered lotic systems with consequent effects on the biodiversity of freshwater fauna. Ictalurids are a diverse group of fishes and play an important ecological role in aquatic ecosystems. However, little is known about their distribution and status in lotic systems throughout Iowa. The...

2011, Journal of Environmental & Engineering Geophysics (16) 145-164
Self-potential and direct current resistivity surveys are carried out at the Hidden Dam site in Raymond, California to assess present-day seepage patterns and better understand the hydrogeologic mechanisms that likely influence seepage.

Density estimation in a wolverine population using spatial capture-recapture models
J. Andrew Royle, Audrey J. Magoun, Beth Gardner, Patrick Valkenbury, Richard E. Lowell
Kevin McKelvey, editor(s)
2011, Journal of Wildlife Management (75) 604-611
Classical closed-population capture-recapture models do not accommodate the spatial information inherent in encounter history data obtained from camera-trapping studies. As a result, individual heterogeneity in encounter probability is induced, and it is not possible to estimate density objectively because trap arrays do not have a well-defined sample area. We applied...

Treatment of anchor pixels in the METRIC model for improved estimation of sensible and latent heat fluxes
Ramesh K. Singh, A. Irmak
2011, Hydrological Sciences Journal (56) 895-906
Reliable estimation of sensible heat flux (H) is important in energy balance models for quantifying evapotranspiration (ET). This study was conducted to evaluate the value of adding the Priestley-Taylor (PT) equation to the METRIC (Mapping Evapotranspiration at high Resolution with Internalized Calibration) model. METRIC was used to estimate energy fluxes...
Hydrologic assessment of three drainage basins in the Pinelands of southern New Jersey, 2004-06
Richard L. Walker, Robert S. Nicholson, Donald A. Storck
2011, Scientific Investigations Report 2011-5056
The New Jersey Pinelands is an ecologically diverse area in the southern New Jersey Coastal Plain, most of which overlies the Kirkwood-Cohansey aquifer system. The demand for groundwater from this aquifer system is increasing as local development increases. Because any increase in groundwater withdrawals has the potential to affect streamflows...

2011, Quaternary Science Reviews (30) 364-376
Quantitative estimates of land-level change during the giant AD 1700 Cascadia earthquake along the Oregon coast are inferred from relative sea-level changes reconstructed from fossil foraminiferal assemblages preserved within the stratigraphic record. A transfer function, based upon a regional training set of modern sediment samples from Oregon estuaries, is calibrated...
