2011, Book chapter, Earthquake Data in Engineering Seismology: Predictive Models, Data Management, and Networks
The PEER NGA ground-motion prediction equations (GMPEs) were derived by five developer teams over several years, resulting in five sets of GMPEs. The teams used various subsets of a global database of ground motions and metadata from shallow earthquakes in tectonically active regions in the development of the equations. Since...

2011, Book chapter, Advances in environmental remote sensing
Land-cover composition and change have profound impacts on terrestrial ecosystems. Land-cover and land-use (LCLU) conditions and their changes can affect social and physical environments by altering ecosystem conditions and services. Information about LCLU change is often used to produce landscape-based metrics and evaluate landscape conditions to monitor LCLU status and...

2011, Book chapter, Camera traps in animal ecology
Automated photography of tigers Panthera tigris for purely illustrative purposes was pioneered by British forester Fred Champion (1927, 1933) in India in the early part of the Twentieth Century.

Geologic framework influences on the geomorphology of an anthropogenically modified barrier island: Assessment of dune/beach changes at Fire Island, New York
Erika E. Lentz, Cheryl Hapke
2011, Geomorphology (126) 82-96
Antecedent geology plays a crucial role in determining the inner-shelf, nearshore, and onshore geomorphology observed in coastal systems. However, the influence of the geologic framework on a system is difficult to extract when evaluating responses to changes due to storms and anthropogenic modifications, and few studies have quantified the potential...

2011, Conference Paper, Proceedings of the workshop on engineered barrier performance related to low-level radioactive waste, decommissioning, and uranium mill tailings facilities (NUREG/CP-0195)
In 1976 the U.S. Geological Survey (USGS) began studies of unsaturated zone hydrology next to the Nation’s first commercial disposal facility for low-level radioactive waste (LLRW) near Beatty, NV. Recognizing the need for long-term data collection, the USGS in 1983 established research management areas in the vicinity of the waste-burial...

2011, Journal of the American Water Resources Association (47) 254-264
Mass loadings were calculated for four pesticides in two watersheds with different land uses in the Central Valley, California, by using two parametric models: (1) the Seasonal Wave model (SeaWave), in which a pulse signal is used to describe the annual cycle of pesticide occurrence in a stream, and (2)...
Coherence of river and ocean conditions along the US West Coast during storms
T. A. Kniskern, Jonathan A. Warrick, K.L. Farnsworth, R. A. Wheatcroft, M.A. Goni
2011, Continental Shelf Research (31) 789-805
The majority of water and sediment discharge from the small, mountainous watersheds of the US West Coast occurs during and immediately following winter storms. The physical conditions (waves, currents, and winds) within and acting upon the proximal coastal ocean during these winter storms strongly influence dispersal patterns. We examined this...

Management case study: Tampa Bay, Florida
Gerold Morrison, Holly Greening, Kimberly K. Yates
Eric Wolanski, Donald S. McLusky, editor(s)
2011, Book chapter, Management of Estuaries and Coasts
Tampa Bay, Florida, USA, is a shallow, subtropical estuary that experienced severe cultural eutrophication between the 1940s and 1980s, a period when the human population of its watershed quadrupled. In response, citizen action led to the formation of a public- and private-sector partnership (the Tampa Bay Estuary Program), which...
Chapter 3: Changes to the Wyoming Basins landscape from oil and natural gas development
Sean P. Finn, Steven T. Knick
2011, Book chapter, Sagebrush ecosystem conservation and management: Ecoregional assessment tools and models for the Wyoming Basins
Oil and natural gas have been produced in Wyoming since the late 1800s although the rate of extraction has increased substantially in the last two decades. Well pads, roads, and infrastructure built to support resource development alter native vegetation configuration; however, the rate and effect of land cover change resulting...
Mechanical analysis of fault slip data: Implications for paleostress analysis
J. Ole Kaven, F. Maerten, D. D. Pollard
2011, Journal of Structural Geology (33) 78-91
Stress inversions are a useful and popular tool for structural geologist and seismologist alike. These methods were first introduced by Wallace (1951) and Bott (1959) and subsequent studies continue to be based on their assumptions: the remote stress tensor is spatially uniform for the rock mass containing the faults and temporally constant over the history of...

B. G. Katz, S. M. Eberts, L. J. Kauffman
2011, Journal of Hydrology (397) 151-166
A detailed review was made of chemical indicators used to identify impacts from septic tanks on groundwater quality. Potential impacts from septic tank leachate on groundwater quality were assessed using the mass ratio of chloride–bromide (Cl/Br), concentrations of selected chemical constituents, and ancillary information (land use, census data, well...
Water quality and trophic status of Fort Cobb Reservoir, southwestern Oklahoma, 2016: Chapter 8 in Assessment of conservation practices in the Fort Cobb Reservoir watershed, southwestern Oklahoma
James F. Fairchild, Ann L. Allert, Kathy R. Echols
2011, Scientific Investigations Report 2010-5257-8
Eutrophication of reservoirs frequently occurs because of excessive nutrient inputs caused by anthropogenic activities, including row-crop agriculture. The trophic status of Fort Cobb Reservoir, Oklahoma, was assessed in April, July, and September 2006. The Fort Cobb Reservoir was highly eutrophic, with the greatest concentrations of nutrients and chlorophyll-a being measured...
Effect of land cover change on runoff curve number estimation in Iowa, 1832-2001
Loren L. Wehmeyer, Frank H. Weirich, Thomas F. Cuffney
2011, Ecohydrology (4) 315-321
Within the first few decades of European-descended settlers arriving in Iowa, much of the land cover across the state was transformed from prairie and forest to farmland, patches of forest, and urbanized areas. Land cover change over the subsequent 126 years was minor in comparison. Between 1832 and 1859, the...
Proposed standard weight (W(s)) equations for interior cutthroat trout
C.G. Kruse, W.A. Hubert
2011, North American Journal of Fisheries Management (17) 784-790
We developed standard weight (W(s); length-specific standard weight for the species) equations for inland cutthroat trout Oncorhynchus clarki using the regression-line-percentile technique. Length and weight data from samples of 117 cutthroat trout populations (48 lentic and 69 lotic) over the interior range of the species were used. Separate W(s) equations...

Dale W. Griffin, C. Gonzalez, N. Teigell, Terry Petrosky, D.E. Northup, M. Lyles
2011, Aerobiologia (27) 25-35
The influence of sample-collection-time on the recovery of culturable airborne microorganisms using a low-flow-rate membrane-filtration unit and a high-flow-rate liquid impinger were investigated. Differences in recoveries were investigated in four different atmospheric environments, one mid-oceanic at an altitude of ~10.0 m, one on a mountain top at an altitude of ~3,000.0 m,...

2010, Open-File Report 2010-1146
A coastal vulnerability index (CVI) was used to map the relative vulnerability of the coast to future sea-level rise along the Northern Gulf of Mexico from Galveston, TX, to Panama City, FL. The CVI ranks the following in terms of their physical contribution to sea-level rise-related coastal change: geomorphology, regional...
Patterns of use and distribution of king eiders and black scoters during the annual cycle in northeastern Bristol Bay, Alaska
Jason L Schamber, Paul L. Flint, Abby N. Powell
2010, Marine Biology (157) 2169-2176
Northeastern Bristol Bay, Alaska, which includes three large estuaries, is used by multiple sea duck species during the annual cycle. Limited aerial surveys indicate that this area supports tens of thousands of king eiders and black scoters during spring migration and the autumn molt. Existing satellite telemetry data were used...
