Solar thematic maps for space weather operations
E. Joshua Rigler, Steven M. Hill, Alysha A. Reinard, Robert A. Steenburgh
2012, Space Weather (10)
Thematic maps are arrays of labels, or "themes", associated with discrete locations in space and time. Borrowing heavily from the terrestrial remote sensing discipline, a numerical technique based on Bayes' theorem captures operational expertise in the form of trained theme statistics, then uses this to automatically assign labels to solar...

New "Risk-Targeted" Seismic Maps Introduced into Building Codes
Nicholas Luco, B. Garrett, J. Hayes
2012, Report, Seismic Waves
Throughout most municipalities of the United States, structural engineers design new buildings using the U.S.-focused International Building Code (IBC). Updated editions of the IBC are published every 3 years. The latest edition (2012) contains new "risk-targeted maximum considered earthquake" (MCER) ground motion maps, which are enabling engineers to incorporate a...

Advances in carbonate exploration and reservoir analysis
J. Garland, J. Neilson, S.E. Laubach, Katherine J. Whidden
2012, Geological Society Special Publication (370) 1-15
The development of innovative techniques and concepts, and the emergence of new plays in carbonate rocks are creating a resurgence of oil and gas discoveries worldwide. The maturity of a basin and the application of exploration concepts have a fundamental influence on exploration strategies. Exploration success often occurs in underexplored...
Fate and transport of glyphosate and aminomethylphosphonic acid in surface waters of agricultural basins
Richard H. Coupe, Stephen J. Kalkhoff, Paul D. Capel, Caroline Gregoire
2012, Pest Management Science (68) 16-30
BACKGROUND: Glyphosate [N-(phosphonomethyl)glycine] is a herbicide used widely throughout the world in the production of many crops and is heavily used on soybeans, corn and cotton. Glyphosate is used in almost all agricultural areas of the United States, and the agricultural use of glyphosate has increased from less than 10...
Using multitemporal remote sensing imagery and inundation measures to improve land change estimates in coastal wetlands
Y.C. Allen, B.R. Couvillion, J.A. Barras
2012, Estuaries and Coasts (35) 190-200
Remote sensing imagery can be an invaluable resource to quantify land change in coastal wetlands. Obtaining an accurate measure of land change can, however, be complicated by differences in fluvial and tidal inundation experienced when the imagery is captured. This study classified Landsat imagery from two wetland areas in coastal...
The population structure of Escherichia coli isolated from subtropical and temperate soils
Muruleedhara N. Byappanahalli, Tao Yan, Matthew J. Hamilton, Satoshi Ishii, Roger S. Fujioka, Richard L. Whitman, Michael J. Sadowsky
2012, Science of the Total Environment (417-418) 273-279
While genotypically-distinct naturalized Escherichia coli strains have been shown to occur in riparian soils of Lake Michigan and Lake Superior watersheds, comparative analyses of E. coli populations in diverse soils across a range of geographic and climatic conditions have not been investigated. The main objectives of this study were to:...
An investigation of element ratios for assessing suspended-sediment sources in small agricultural basins
K. Juracek
2012, Physical Geography (33) 50-67
Various sediment properties previously have been investigated for the purpose of determining sources of suspended sediment. A remaining research need is an assessment of element ratios for the determination of suspended-sediment sources in different terrestrial environments. In this study, 253 element ratios were assessed to determine which, if any, were...
GONe: Software for estimating effective population size in species with generational overlap
J.A. Coombs, B. H. Letcher, K.H. Nislow
2012, Molecular Ecology Resources (12) 160-163
GONe is a user‐friendly, Windows‐based program for estimating effective size (Ne) in populations with overlapping generations. It uses the Jorde–Ryman modification to the temporal method to account for age structure in populations. This method requires estimates of age‐specific survival and birth rate and allele frequencies measured in...
Modifications to the conduit flow process mode 2 for MODFLOW-2005
Thomas Reimann, S. Birk, C. Rehrl, W. Barclay Shoemaker
2012, Ground Water (50) 144-148
As a result of rock dissolution processes, karst aquifers exhibit highly conductive features such as caves and conduits. Within these structures, groundwater flow can become turbulent and therefore be described by nonlinear gradient functions. Some numerical groundwater flow models explicitly account for pipe hydraulics by coupling the continuum model with...
Ultra-high resolution four dimensional geodetic imaging of engineered structures for stability assessment
Gerald W. Bawden, Sandra Bond, J. H. Podoski, O. Kreylos, L. H. Kellogg
2012, Conference Paper, GeoCongress 2012
We used ground-based Tripod LiDAR (T-LiDAR) to assess the stability of two engineered structures: a bridge spanning the San Andreas fault following the M6.0 Parkfield earthquake in Central California and a newly built coastal breakwater located at the Kaumālapa`u Harbor Lana'i, Hawaii. In the 10 weeks following the earthquake, we...
Life history of the fluted kidneyshell Ptychobranchus subtentum
V.M. Davis, J.B. Layzer
2012, American Midland Naturalist (167) 79-95
The fluted kidneyshell Ptychobranchus subtentum (Say, 1825) is a candidate for listing under the Endangered Species Act by the US Fish and Wildlife Service. Fecundity, fish hosts, and selected population demographics were determined during 2005–2006 for the fluted kidneyshell in the upper Clinch River, Hancock County, Tennessee. Females were fertilized in Aug....
Wildfire impacts on the processes that generate debris flows in burned watersheds
M. Parise, Susan H. Cannon
2012, Natural Hazards (61) 217-227
Every year, and in many countries worldwide, wildfires cause significant damage and economic losses due to both the direct effects of the fires and the subsequent accelerated runoff, erosion, and debris flow. Wildfires can have profound effects on the hydrologic response of watersheds by changing the infiltration characteristics and erodibility...
Spatio-temporal variation in male white-tailed deer harvest rates in Pennsylvania: Implications for estimating abundance
Andrew S. Norton, Duane R. Diefenbach, Bret D. Wallingford, Christopher S. Rosenberry
2012, Journal of Wildlife Management (76) 136-143
The performance of 2 popular methods that use age-at-harvest data to estimate abundance of white-tailed deer is contingent on assumptions about variation in estimates of subadult (1.5 yr old) and adult (≥2.5 yr old) male harvest rates. Auxiliary data (e.g., estimates of survival or harvest rates from radiocollared animals) can be used...
Forest Succession and Maternity Day roost selection by Myotis septentrionalis in a mesophytic hardwood forest
Alexander Silvis, W. Mark Ford, Eric R. Britzke, Nathan R. Beane, Joshua B. Johnson
2012, International Journal of Forestry Research (2012)
Conservation of summer maternity roosts is considered critical for bat management in North America, yet many aspects of the physical and environmental factors that drive roost selection are poorly understood. We tracked 58 female northern bats (Myotis septentrionalis) to 105 roost trees of 21 species on the Fort Knox military...

Ryan Gold, William Stephenson, Jack Odum, Rich Briggs, Anthony Crone, Steve Angster
2012, Report, Guidebook: neotectonics of the Lake Tahoe and Carson and Sierra Valleys, F.O.P. 2012
The Grizzly Valley fault system (GVFS) strikes northwestward across Sierra Valley, California and is part of a network of active, dextral strike-slip faults in the northern Walker Lane (Figure 1). To investigate Quaternary motion across the GVFS, we analyzed high-resolution (0.25 m) airborne LiDAR data (Figure 2) in combination with...
Ordovician of the Sauk megasequence in the Ozark region of northern Arkansas and parts of Missouri and adjacent states
Raymond L. Ethington, John E. Repetski, James R. Derby
2012, AAPG Memoir (98) 275-300
Exposures of Ordovician rocks of the Sauk megasequence in Missouri and northern Arkansas comprise Ibexian and lower Whiterockian carbonates with interspersed sandstones. Subjacent Cambrian strata are exposed in Missouri but confined to the subsurface in Arkansas. The Sauk-Tippecanoe boundary in this region is at the base of the St. Peter...
