Calculation of hydrocarbon-in-place in gas and gas-condensate reservoirs - Carbon dioxide sequestration
Mahendra K. Verma
2012, Open-File Report 2012-1033
The Energy Independence and Security Act of 2007 (Public Law 110-140) authorized the U.S. Geological Survey (USGS) to conduct a national assessment of geologic storage resources for carbon dioxide (CO2), requiring estimation of hydrocarbon-in-place volumes and formation volume factors for all the oil, gas, and gas-condensate reservoirs within the U.S....

Cory P. McDonald, Jennifer Rover, Edward G. Stets, Robert G. Striegl
2012, Limnology and Oceanography (57) 597-606
We analyzed complete geospatial data for the 3.5 million lakes and reservoirs larger than 0.001 km2, with a combined surface area of 131,000 km2, in the contiguous United States (excluding the Laurentian Great Lakes) and identified their regional distribution characteristics. For Alaska, we also analyzed (1) incomplete data that suggest...

Database for volcanic processes and geology of Augustine Volcano, Alaska
Jacqueline McIntire, David W. Ramsey, Evan Thoms, Richard B. Waitt, James E. Beget
2012, Data Series 677
Augustine Island (volcano) in lower Cook Inlet, Alaska, has erupted repeatedly in late-Holocene and historical times. Eruptions typically beget high-energy volcanic processes. Most notable are bouldery debris avalanches containing immense angular clasts shed from summit domes. Coarse deposits of these avalanches form much of Augustine's lower flanks. This geologic map...
The role of fire-return interval and season of burn in snag dynamics in a south Florida slash pine forest
John D. Lloyd, Gary L. Slater, James R. Snyder
2012, Fire Ecology (8) 18-31
Standing dead trees, or snags, are an important habitat element for many animal species. In many ecosystems, fire is a primary driver of snag population dynamics because it can both create and consume snags. The objective of this study was to examine how variation in two key components of...

Paul M. Bradley, Celeste A. Journey, Julie D. Kirshtein, Mary A. Voytek, Pierre J. Lacombe, Thomas E. Imbrigiotta, Francis H. Chapelle, Claire R. Tiedeman, Daniel J. Goode
2012, Remediation Journal (22) 21-32
Significant microbial reductive dechlorination of [1,2 14C] cis-dichloroethene (DCE) was observed in anoxic microcosms prepared with unamended, fractured rock aquifer materials, which were colonized in situ at multiple depths in two boreholes at the Naval Air Warfare Center (NAWC) in West Trenton, New Jersey. The lack of significant reductive dechlorination...
Algal community characteristics and response to nitrogen and phosphorus concentrations in streams in the Ozark Plateaus, Southern Missouri, 1993-95 and 2006-07
Suzanne R. Femmer

Nutrient and algae data were collected in the 1990s and 2000s by the U.S. Geological Survey for the National Water- Quality Assessment program in the Ozark Highlands, southern Missouri. These data were collected at sites of differing drainage area, land use, nutrient concentrations, and physiography. All samples were collected at...
Sea-level history during the Last Interglacial complex on San Nicolas Island, California: implications for glacial isostatic adjustment processes, paleozoogeography and tectonics
Daniel R. Muhs, Kathleen R. Simmons, R. Randall Schumann, Lindsey T. Groves, Jerry X. Mitrovica, Deanna Laurel
2012, Quaternary Science Reviews (37) 1-25
San Nicolas Island, California has one of the best records of fossiliferous Quaternary marine terraces in North America, with at least fourteen terraces rising to an elevation of ~270 m above present-day sea level. In our studies of the lowest terraces, we identified platforms at 38-36 m (terrace 2a), 33-28...

Surface Mass Balance of the Columbia Glacier, Alaska, 1978 and 2010 Balance Years
Shad O’Neel
2012, Data Series 676
Although Columbia Glacier is one of the largest sources of glacier mass loss in Alaska, surface mass balance measurements are sparse, with only a single data set available from 1978. The dearth of surface mass-balance data prohibits partitioning of the total mass losses between dynamics and surface forcing; however, the...
Dissolved oxygen as an indicator of bioavailable dissolved organic carbon in groundwater
Francis H. Chapelle, Paul M. Bradley, Peter B. McMahon, Karl Kaiser, Ron Benner
2012, Ground Water (50) 230-241
Concentrations of dissolved oxygen (DO) plotted vs. dissolved organic carbon (DOC) in groundwater samples taken from a coastal plain aquifer of South Carolina (SC) showed a statistically significant hyperbolic relationship. In contrast, DO-DOC plots of groundwater samples taken from the eastern San Joaquin Valley of California (CA) showed a random...
Land change variability and human-environment dynamics in the United States Great Plains
Mark A. Drummond, Roger F. Auch, Krista A. Karstensen, Kristi Sayler, Janis L. Taylor, Thomas R. Loveland
2012, Land Use Policy (29) 710-723
Land use and land cover changes have complex linkages to climate variability and change, biophysical resources, and socioeconomic driving forces. To assess these land change dynamics and their causes in the Great Plains, we compare and contrast contemporary changes across 16 ecoregions using Landsat satellite data and statistical analysis. Large-area...
Life histories, salinity zones, and sublethal contributions of contaminants to pelagic fish declines illustrated with a case study of San Francisco Estuary, California, USA
Marjorie L. Brooks, Erica Fleishman, Larry R. Brown, Peggy W. Lehman, Inge Werner, Nathaniel Scholz, Carys Michelmore, James R. Loworn, Michael L. Johnson, Daniel Schlenk
2012, Estuaries and Coasts (35) 603-621
Human effects on estuaries are often associated with major decreases in abundance of aquatic species. However, remediation priorities are difficult to identify when declines result from multiple stressors with interacting sublethal effects. The San Francisco Estuary offers a useful case study of the potential role of contaminants in declines of...
Bird-habitat relationships in interior Columbia Basin shrubsteppe
S.L. Earnst, A.L. Holmes
2012, The Condor (114) 15-29
Vegetation structure is considered an important habitat feature structuring avian communities. In the sagebrush biome, both remotely-sensed and field-acquired measures of big sagebrush (Artemisia tridentata) cover have proven valuable in understanding avian abundance. Differences in structure between the exotic annual cheatgrass (Bromus tectorum) and native bunchgrasses are also expected to...
Nonlinear effects of group size on the success of wolves hunting elk
Daniel R. MacNulty, Douglas W. Smith, L. David Mech, John A. Vucetich, Craig Packer
2012, Behavioral Ecology (23) 75-82
Despite the popular view that social predators live in groups because group hunting facilitates prey capture, the apparent tendency for hunting success to peak at small group sizes suggests that the formation of large groups is unrelated to prey capture. Few empirical studies, however, have tested for nonlinear relationships between...
