Forecasting carbon budget under climate change and CO2 fertilization for subtropical region in China using integrated biosphere simulator (IBIS) model
Q. Zhu, H. Jiang, J. Liu, C. Peng, X. Fang, S. Yu, G. Zhou, X. Wei, W. Ju
2011, Polish Journal of Ecology (59) 3-24
The regional carbon budget of the climatic transition zone may be very sensitive to climate change and increasing atmospheric CO2 concentrations. This study simulated the carbon cycles under these changes using process-based ecosystem models. The Integrated Biosphere Simulator (IBIS), a Dynamic Global Vegetation Model (DGVM), was used to evaluate the...

Kishor Jaiswal, David J. Wald, Paul S. Earle, Keith A. Porter, Mike Hearne
2011, Book chapter, Human casualties in earthquakes: progress in modelling and mitigation
Since the launch of the USGS’s Prompt Assessment of Global Earthquakes for Response (PAGER) system in fall of 2007, the time needed for the U.S. Geological Survey (USGS) to determine and comprehend the scope of any major earthquake disaster anywhere in the world has been dramatically reduced to less than...
Overview of prohibited and permitted plant regulatory listing systems
Randy G. Westbrooks, Alan V. Tasker
2011, Book chapter, Invasive plant management issues and challenges in the United States: 2011 Overview
Pest risk analysis is a process that evaluates the risks involved with a proposed species to help determine whether it should be permitted or denied entry into a country, and how the risks could be managed if it is imported. The prohibited listing approach was developed in the late 1800s...
Variations in eruption style during the 1931A.D. eruption of Aniakchak volcano, Alaska
R.S. Nicholson, J.E. Gardner, C.A. Neal
2011, Journal of Volcanology and Geothermal Research (207) 69-82
The 1931 A.D. eruption of Aniakchak volcano, Alaska, progressed from subplinian to effusive eruptive style and from trachydacite to basaltic andesite composition from multiple vent locations. Eyewitness accounts and new studies of deposit stratigraphy provide a combined narrative of eruptive events. Additional field, compositional, grain size, componentry, density, and grain morphology...

Peter D. Warwick, Alexander K. Karlsen, Matthew D. Merrill, Brett J. Valentine, editor(s)
2011, Book chapter, Geologic assessment of coal in the Gulf of Mexico coastal plain
The Wilcox Group of central Texas contains shallow (less than 500 ft) coal deposits that are mined for use in mine-mouth electric power generating plants. These coal deposits range in apparent rank from lignite to sub-bituminous (Pierce et al., 2011) and are similar in rank and composition to shallow coal...
Strategy to control the invasive alien tree Miconia calvescens in Pacific islands: Eradication, containment or something else?
Jean-Yves Meyer, Lloyd Loope, Anne-Claire Goarant
C.R. Veitch, M.N. Clout, D. R. Towns, editor(s)
2011, Conference Paper, Island invasives: Eradication and management
Miconia calvescens (Melastomataceae) is a notorious plant invader in the tropical islands of French Polynesia, Hawaii and New Caledonia. A small tree native to Central and South America, it was first introduced as an ornamental in private botanic gardens in Tahiti (1937), Honolulu (1961), and...

Christopher R. Sherwood
Julie D. Rosati, Ping Wang, Tiffany M. Roberts, editor(s)
2011, Conference Paper, The proceedings of the Coastal Sediments 2011
Roughness lengths are used in wave-current bottom boundary layer models to parameterize drag associated with grain roughness, the effect of saltating grains during sediment transport, and small-scale bottom topography (ripples and biogenic features). We made field measurements of flow parameters and recorded sonar images of ripples at the boundary of...

2011, Conference Paper, The proceedings of the Coastal Sediments 2011
This study demonstrates the applicability of a Bayesian probabilistic model as an effective tool in predicting post-storm beach changes along sandy coastlines. Volume change and net shoreline movement are modeled for two study sites at Fire Island, New York in response to two extratropical storms in 2007 and 2009. Both...
Cold-water coral distributions in the Drake Passage area from towed camera observations - Initial interpretations
Rhian G. Waller, Kathryn Scanlon Catanach, Laura F. Robinson
2011, PLoS ONE (6)
Seamounts are unique deep-sea features that create habitats thought to have high levels of endemic fauna, productive fisheries and benthic communities vulnerable to anthropogenic impacts. Many seamounts are isolated features, occurring in the high seas, where access is limited and thus biological data scarce. There are numerous seamounts within the...
Historical trends of hypoxia in Changjiang River estuary: Applications of chemical biomarkers and microfossils
X. Li, T.S. Bianchi, Z. Yang, L.E. Osterman, M. A. Allison, Steven F. DiMarco, G. Yang
2011, Journal of Marine Systems (86) 57-68
Over the past two decades China has become the largest global consumer of fertilizers, which has enhanced river nutrient fluxes and caused eutrophication and hypoxia in the Yangtze (Changjiang) large river delta-front estuary (LDE). In this study, we utilized plant pigments, lignin-phenols, stable isotopes (δ13C and δ15N) and foraminiferal microfossils...

John Y. Takekawa, N.J. Hill, A.K. Schultz, S. A. Iverson, C.J. Cardona, W.M. Boyce, J.P. Dudley
2011, Journal of Visualized Experiments (54)
Wild birds have been implicated in the spread of highly pathogenic avian influenza (HPAI) of the H5N1 subtype, prompting surveillance along migratory flyways. Sampling of wild birds for avian influenza virus (AIV) is often conducted in remote regions, but results are often delayed because of the need to transport samples...

R.A. Locke II, I.G. Krapac, J.L. Lewicki, E. Curtis-Robinson
2011, Conference Paper, Energy Procedia
The Midwest Geological Sequestration Consortium is conducting a large-scale carbon capture and storage (CCS) project in Decatur, Illinois, USA to demonstrate the ability of a deep saline formation to store one million tonnes of carbon dioxide (CO2) from an ethanol facility. Beginning in early 2011, CO2 will be injected at...

S.J. Wilson, R.B. Hunter, Timothy S. Collett, S. Hancock, R. Boswell, B.J. Anderson
2011, Marine and Petroleum Geology (28) 460-477
A series of gas hydrate development scenarios were created to assess the range of outcomes predicted for the possible development of the “Eileen” gas hydrate accumulation, North Slope, Alaska. Production forecasts for the “reference case” were built using the 2002 Mallik production tests, mechanistic simulation, and geologic studies conducted...
Distribution, population status and trends of Kittlitz's murrelet Brachyramphus brevirostris in Lower Cook Inlet and Kachemak Bay, Alaska
Kathy J. Kuletz, Suzann G. Speckman, John F. Piatt, E.A. Labunski
2011, Marine Ornithology: Journal of Seabird Research and Conservation (39) 85-95
Lower Cook Inlet (LCI) in south-central Alaska is unusual among the breeding areas of Kittlitz's Murrelet Brachyramphus brevirostris because of human impacts on the marine and terrestrial environments and because of the lack of tidewater glaciers. In LCI the Kittlitz's Murrelet co-exists with the more abundant Marbled Murrelet, which complicates...

Integration of paleoseismic data from multiple sites to develop an objective earthquake chronology: Application to the Weber segment of the Wasatch fault zone, Utah
C. B. DuRoss, S. F. Personius, A. J. Crone, S.S. Olig, W.R. Lund
2011, Bulletin of the Seismological Society of America (101) 2765-2781
We present a method to evaluate and integrate paleoseismic data from multiple sites into a single, objective measure of earthquake timing and recurrence on discrete segments of active faults. We apply this method to the Weber segment (WS) of the Wasatch fault zone using data from four fault-trench studies completed...
