Catherine B. Enomoto, James L. Coleman Jr., Christopher S. Swezey, Patrick W. Niemeyer, Frank T. Dulong
2015, Open-File Report 2015-1061
Reconnaissance field mapping and outcrop sampling for geochemical and mineralogical analyses indicate that the Middle Devonian Marcellus Shale in the Broadtop synclinorium and nearby areas from southeastern West Virginia to south-central Pennsylvania has an organic content sufficiently high and a thermal maturity sufficiently moderate to be considered for a shale...

Peter R. Claggett, Hearn Jr., David I. Donato
2015, Open-File Report 2014-1125
The Southeast Regional Partnership for Planning and Sustainability (SERPPAS) was formed in 2005 as a partnership between the Department of Defense (DOD) and State and Federal agencies to promote better collaboration in making resource-use decisions. In support of this goal, the U.S. Geological Survey (USGS) conducted a study to evaluate...
A field investigation of the basaltic ring structures of the Channeled Scabland and the relevance to Mars
Laszlo P. Keszthelyi, Windy L. Jaeger
2015, Geomorphology (240) 34-43
The basaltic ring structure (BRS) is a class of peculiar features only reported in the Channeled Scabland of eastern Washington State. They have been suggested to be good analogs, however, for some circular features on Mars. BRSs are found where Pleistocene floods scoured the Columbia River Basin, stripping off the...

Andrew J. Massey, Richard J. Verdi
2015, Open-File Report 2015-1081
The U.S. Geological Survey (USGS) deployed a temporary monitoring network of six storm surge sensors and four barometric pressure sensors along the Atlantic coast in eastern Massachusetts, from Plymouth to Newburyport, before the blizzard of January 26–28, 2015 (Blizzard of January 2015), to record the timing and magnitude of storm...
Thiaminase activity in native freshwater mussels
Carrie J. Blakeslee, Stephanie Sweet, Heather S. Galbraith, Dale C. Honeyfield
2015, Journal of Great Lakes Research (41) 516-519
Thiamine (vitamin B1) deficiency in the Great Lakes has been attributed to elevated levels of thiaminase I enzyme activity in invasive prey species; however, few studies have investigated thiaminase activity in native prey species. Some of the highest levels of thiaminase activity have been measured in invasive dreissenid mussels with...
Inter-laboratory variation in the chemical analysis of acidic forest soil reference samples from eastern North America
Donald S. Ross, Scott W Bailiey, Russell D Briggs, Johanna Curry, Ivan J. Fernandez, Guinevere Fredriksen, Christine L. Goodale, Paul W. Hazlett, Paul R Heine, Chris E. Johnson, John T Larson, Gregory B. Lawrence, Randy K Kolka, Ouimet, D Pare, Daniel D. Richter, Charles D Shirmer, Richard A.F. Warby
2015, Ecosphere (6) 1-22
Long-term forest soil monitoring and research often requires a comparison of laboratory data generated at different times and in different laboratories. Quantifying the uncertainty associated with these analyses is necessary to assess temporal changes in soil properties. Forest soil chemical properties, and methods to measure these properties, often differ from...
Population connectivity of endangered Ozark big-eared bats (Corynorhinus townsendii ingens)
Dana N. Lee, Richard C. Stark, William L. Puckette, Meredith J. Hamilton, David M. Leslie Jr., Ronald A. Van Den Bussche
2015, Journal of Mammalogy (96) 522-530
The endangered Ozark big-eared bat (Corynorhinus townsendii ingens) is restricted to eastern Oklahoma and western and north-central Arkansas, where populations may be susceptible to losses of genetic variation due to patchy distribution of colonies and potentially small effective population sizes. We used mitochondrial D-loop DNA sequences and 15 nuclear microsatellite...
Comparison of three preservation techniques for slowing dissolution of calcareous nannofossils in organic rich sediments
Ellen Seefelt, Jean Self-Trail, Arthur P. Schultz
2015, Micropaleontology (61) 149-164
In an attempt to halt or reduce dissolution of calcareous nannofossils in organic and/or pyrite-rich sediments, three different methods of short-term storage preservation were tested for efficacy: vacuum packing, argon gas replacement, and buffered water. Abundance counts of calcareous nannofossil assemblages over a six month period showed that none of...
What lies beneath: geophysical mapping of a concealed Precambrian intrusive complex along the Iowa–Minnesota border
Benjamin J. Drenth, Raymond R. Anderson, Klaus J. Schulz, Joshua M. Feinberg, Val W. Chandler, William F. Cannon
2015, Canadian Journal of Earth Sciences (52) 279-293
Large-amplitude gravity and magnetic highs over northeast Iowa are interpreted to reflect a buried intrusive complex composed of mafic–ultramafic rocks, the northeast Iowa intrusive complex (NEIIC), intruding Yavapai province (1.8–1.72 Ga) rocks. The age of the complex is unproven, although it has been considered to be Keweenawan (∼1.1 Ga). Because...

Modelling the enigmatic Late Pliocene Glacial Event - Marine Isotope Stage M2
Aisling M. Dolan, Alan M. Haywood, Stephen J. Hunter, Julia C. Tindall, Harry J. Dowsett, Daniel J. Hill, Steven J. Pickering
2015, Global and Planetary Change (128) 47-60
The Pliocene Epoch (5.2 to 2.58 Ma) has often been targeted to investigate the nature of warm climates. However, climate records for the Pliocene exhibit significant variability and show intervals that apparently experienced a cooler than modern climate. Marine Isotope Stage (MIS) M2 (~ 3.3 Ma) is a globally recognisable cooling event that...

Gully annealing by fluvially-sourced Aeolian sand: remote sensing investigations of connectivity along the Fluvial-Aeolian-hillslope continuum on the Colorado River
Joel B. Sankey, Amy E. East, Brian D. Collins, Joshua J. Caster
2015, Conference Paper, Proceedings of the Joint Federal Interagency Conference 2015
Processes contributing to development of ephemeral gully channels are of great importance to landscapes worldwide, and particularly in dryland regions where soil loss and land degradation from gully erosion pose long-term, land-management problems. Whereas gully formation has been relatively well studied, much less is known of the processes that anneal...
Characterization of streamflow, salinity, and selenium loading and land-use change in Montrose Arroyo, western Colorado, from 1992 to 2013
Rodney J. Richards, Jennifer L. Moore
2015, Scientific Investigations Report 2015-5039
Salinity and dissolved selenium are known water-quality impairments in the lower Gunnison River watershed of western Colorado. Salinity is a concern because of its adverse effects on agricultural land and equipment, and on municipal and industrial users. The Montrose Arroyo watershed in Montrose, Colorado, contains agricultural and residential areas as...
Sediment contributions from floodplains and legacy sediments to Piedmont streams of Baltimore County, Maryland
Mitchell Donovan, Andrew Miller, Matthew Baker, Allen C. Gellis
2015, Geomorphology (235) 88-105
Disparity between watershed erosion rates and downstream sediment delivery has remained an important theme in geomorphology for many decades, with the role of floodplains in sediment storage as a common focus. In the Piedmont Province of the eastern USA, upland deforestation and agricultural land use following European settlement led...

Potential groundwater recharge for the State of Minnesota using the Soil-Water-Balance model, 1996-2010
Erik A. Smith, Stephen M. Westenbroek
2015, Scientific Investigations Report 2015-5038
Groundwater recharge is one of the most difficult components of a water budget to ascertain, yet is an important boundary condition necessary for the quantification of water resources. In Minnesota, improved estimates of recharge are necessary because approximately 75 percent of drinking water and 90 percent of agricultural irrigation water...
National assessment of geologic carbon dioxide storage resources: allocations of assessed areas to Federal lands
Marc L. Buursink, Steven M. Cahan, Peter D. Warwick
2015, Scientific Investigations Report 2015-5021
Following the geologic basin-scale assessment of technically accessible carbon dioxide storage resources in onshore areas and State waters of the United States, the U.S. Geological Survey estimated that an area of about 130 million acres (or about 200,000 square miles) of Federal lands overlies these storage resources. Consequently, about 18...
