2013, Atmospheric Measurement Techniques (6) 677-696
Sulphur dioxide emission rate measurements are an important tool for volcanic monitoring and eruption risk assessment. The SO2 camera technique remotely measures volcanic emissions by analysing the ultraviolet absorption of SO2 in a narrow spectral window between 300 and 320 nm using solar radiation scattered in the atmosphere. The SO2...

2013, Scientific Investigations Report 2013-5168
An investigation was completed to document recent (circa 1998 to 2011) channel-migration rates at 970 meander bends along 38 of the largest streams in Indiana. Data collection was completed by using the Google Earth™ platform and, for each selected site, identifying two images with capture dates separated by multiple years....
Nickel-cobalt laterites: a deposit model
Erin E. Marsh, Eric D. Anderson, Floyd Gray
2013, Scientific Investigations Report 2010-5070-H
Nickel-cobalt (Ni-Co) laterite deposits are supergene enrichments of Ni±Co that form from intense chemical and mechanical weathering of ultramafic parent rocks. These regolith deposits typically form within 26 degrees of the equator, although there are a few exceptions. They form in active continental margins and stable cratonic settings. It takes...

Lois M. Voronin, Jill N. Densmore, Peter Martin, Charles F. Brush, Carl S. Carlson, David M. Miller
2013, Scientific Investigations Report 2013-5101
Groundwater withdrawals began in 1992 from the Langford Basin within the Fort Irwin National Training Center (NTC), California. From April 1992 to December 2010, approximately 12,300 acre-feet of water (averaging about 650 acre-feet per year) has been withdrawn from the basin and transported to the adjacent Irwin Basin. Since withdrawals...

2013, Scientific Investigations Report 2013-5153
Continuous streamflow and turbidity data collected from October 1, 2010, to September 30, 2012, at a site upstream and downstream from Clinton Lake, Kansas, were used to compute the total suspended-sediment load delivered to and released from the reservoir as well as the sediment trap efficiency for the reservoir. Ongoing...
MODFLOW–LGR—Documentation of ghost node local grid refinement (LGR2) for multiple areas and the boundary flow and head (BFH2) package
Steffen W. Mehl, Mary C. Hill
2013, Techniques and Methods 6-A44
This report documents the addition of ghost node Local Grid Refinement (LGR2) to MODFLOW-2005, the U.S. Geological Survey modular, transient, three-dimensional, finite-difference groundwater flow model. LGR2 provides the capability to simulate groundwater flow using multiple block-shaped higher-resolution local grids (a child model) within a coarser-grid parent model. LGR2 accomplishes this...
Report of geomagnetic pulsation indices for space weather applications
Z. Xu, Jennifer L. Gannon, Erin J. Rigler
2013, Open-File Report 2013-1166
The phenomenon of ultra-low frequency geomagnetic pulsations was first observed in the ground-based measurements of the 1859 Carrington Event and has been studied for over 100 years. Pulsation frequency is considered to be “ultra” low when it is lower than the natural frequencies of the plasma, such as the ion...

William C. Burton, Philip T. Harte
2013, Open-File Report 2013-1224
The Savage Municipal Well Superfund site consists of an eastward-directed plume of volatile organic compounds, principally tetrachloroethylene (PCE), in alluvium and glacial sand and gravel in the Souhegan River valley, just south of the river and about 4 kilometers west of the town of Milford, New Hampshire. Sampling of monitoring...
Biological and geochemical data of gravity cores from Mobile Bay, Alabama
Kathryn A. Richwine, Marci Marot, Christopher G. Smith, Lisa E. Osterman, C. Scott Adams
2013, Open-File Report 2013-1240
A study was conducted to understand the marine-influenced environments of Mobile Bay, Alabama, by collecting a series of box cores and gravity cores. One gravity core in particular demonstrates a long reference for changing paleoenvironmental parameters in Mobile Bay. Due to lack of abundance of foraminifers and (or) lack of...
Sex determination of duck embryos: observations on syrinx development
Robert E. Wilson, Sarah A. Sonsthagen, J. Christian Franson
2013, Avian Biology Research (6) 243-246
Ducks exhibit sexual dimorphism in vocal anatomy. Asymmetrical ossification of the syrinx (bulla syringealis) is discernable at about 10 days of age in male Pekin duck (Anas platyrhynchos domestica) embryos, but information is lacking on the early development of the bulla in wild ducks. To evaluate the reliability of this...
Songbird abundance in native and planted grassland varies with type and amount of grassland in the surrounding landscape
Stephen K. Davis, Ryan Fisher, Susan Skinner, Terry L. Shaffer, R. Mark Brigham
2013, Journal of Wildlife Management (77) 908-919
Agriculture and wildlife conservation programs have converted vast amounts of cropland into grasslands planted with exotic species. Understanding how landscape context influences avian use of native and planted grasslands is essential for developing effective conservation strategies in agricultural landscapes. Our primary objective was to determine the extent to which the...
Late Quaternary stratigraphy, sedimentology, and geochemistry of an underfilled lake basin in the Puna (north-west Argentina)
Michael M. McGlue, Andrew S. Cohen, Geoffrey S. Ellis, Andrew L. Kowler
2013, Basin Research (25) 638-658
Depositional models of ancient lakes in thin-skinned retroarc foreland basins rarely benefit from appropriate Quaternary analogues. To address this, we present new stratigraphic, sedimentological and geochemical analyses of four radiocarbon-dated sediment cores from the Pozuelos Basin (PB; northwest Argentina) that capture the evolution of this low-accommodation Puna basin over the...
Caveats on tomographic images
Gillian R. Foulger, Giuliano F. Panza, Irina M. Artemieva, Ian D. Bastow, Fabio Cammarano, John R. Evans, Warren B. Hamilton, Bruce R. Julian, Michele Lustrino, Hans Thybo, Yanovskaya
2013, Terra Nova (25) 258-281
Geological and geodynamic models of the mantle often rely on joint interpretations of published seismic tomography images and petrological/geochemical data. This approach tends to neglect the fundamental limitations of, and uncertainties in, seismic tomography results. These limitations and uncertainties involve theory, correcting for the crust, the lack of rays throughout...

Seth J. Wenger, Nicholas A. Som, Daniel C. Dauwalter, Daniel J. Isaak, Helen M. Neville, Charles H. Luce, Jason B. Dunham, Michael K. Young, Kurt D. Fausch, Bruce E. Rieman
2013, Global Change Biology (19) 3343-3354
Forecasts of species distributions under future climates are inherently uncertain, but there have been few attempts to describe this uncertainty comprehensively in a probabilistic manner. We developed a Monte Carlo approach that accounts for uncertainty within generalized linear regression models (parameter uncertainty and residual error), uncertainty among competing models (model...
Permanently enhanced dynamic triggering probabilities as evidenced by two M ≥ 7.5 earthquakes
Joan S. Gomberg
2013, Geophysical Research Letters (40) 4828-4833
The 2012 M7.7 Haida Gwaii earthquake radiated waves that likely dynamically triggered the 2013M7.5 Craig earthquake, setting two precedents. First, the triggered earthquake is the largest dynamically triggered shear failure event documented to date. Second, the events highlight a connection between geologic structure, sedimentary troughs that act as waveguides, and triggering...

Animal manures, used as a nitrogen source for crop production, are often associated with negative impacts on nutrient levels in surface water. The concentrations of estrogens in streams from these manures also are of concern due to potential endocrine disruption in aquatic species. Streams associated with livestock operations were sampled...

Leafy spurge (Euphorbia esula) affects vegetation more than seed banks in mixed-grass prairies of the Northern Great Plains
Diane L. Larson, Dustin F. Haines, Jennifer L. Larson
2013, Invasive Plant Science and Management (6) 416-432
Exotic plants have the ability to modify soil seed banks in habitats they invade, but little is known about the legacy of invasion on seed banks once an exotic plant has successfully been controlled. Natural areas previously invaded by leafy spurge in the northern Great Plains typically have one of...
