Rintaro Kinoshita, Bianca N. Moebius-Clune, Harold M. van Es, W. Dean Hively, A. Volkan Bilgilis
2012, Soil Science Society of America Journal (76) 1776-1788
Visible and near-infrared reflectance spectroscopy (VNIRS) is a rapid and nondestructive method that can predict multiple soil properties simultaneously, but its application in multidimensional soil quality (SQ) assessment in the tropics still needs to be further assessed. In this study, VNIRS (350–2500 nm) was employed to analyze 227 air-dried soil...

C. Anela Choy, Peter C. Davison, Jeffrey C. Drazen, Adrian Flynn, Elizabeth J. Gier, Joel C. Hoffman, Jennifer P. McClain-Counts, Todd W. Miller, Brian N. Popp, Steve W. Ross, Tracey T. Sutton
2012, PLoS ONE (7) 1-8
The δ15N values of organisms are commonly used across diverse ecosystems to estimate trophic position and infer trophic connectivity. We undertook a novel cross-basin comparison of trophic position in two ecologically well-characterized and different groups of dominant mid-water fish consumers using amino acid nitrogen isotope compositions. We found that trophic...
Harvest and dynamics of duck populations
James S. Sedinger, Mark P. Herzog
2012, Journal of Wildlife Management (76) 1108-1116
The role of harvest in the dynamics of waterfowl populations continues to be debated among scientists and managers. Our perception is that interested members of the public and some managers believe that harvest influences North American duck populations based on calls for more conservative harvest regulations. A recent review of...

Development of the Landsat Data Continuity Mission cloud-cover assessment algorithms
Pat Scaramuzza, M.A. Bouchard, John L. Dwyer
2012, IEEE Transactions on Geoscience and Remote Sensing (50) 1140-1154
The upcoming launch of the Operational Land Imager (OLI) will start the next era of the Landsat program. However, the Automated Cloud-Cover Assessment (CCA) (ACCA) algorithm used on Landsat 7 requires a thermal band and is thus not suited for OLI. There will be a thermal instrument on the Landsat...
Credible occurrence probabilities for extreme geophysical events: earthquakes, volcanic eruptions, magnetic storms
Jeffrey J. Love
2012, Geophysical Research Letters (39)
Statistical analysis is made of rare, extreme geophysical events recorded in historical data -- counting the number of events $k$ with sizes that exceed chosen thresholds during specific durations of time $\tau$. Under transformations that stabilize data and model-parameter variances, the most likely Poisson-event occurrence rate, $k/\tau$, applies for frequentist...

2012, Open-File Report 2012-1263
The U.S. Geological Survey (USGS) deployed a temporary monitoring network of water-level and barometric pressure sensors at 127 locations along the gulf coast from Alabama to Louisiana to record the timing, areal extent, and magnitude of hurricane storm tide and coastal flooding generated by Hurricane Isaac. This deployment was undertaken...

Krysten L. Schuler, David E. Green, Anne E. Justice-Allen, Rosemary Jaffe, Mark Cunningham, Nancy J. Thomas, Marilyn G. Spalding, S. Ip
2012, EcoHealth (9) 163-170
Eurasian collared doves (Streptopelia decaocto) have expanded their range across the United States since their introduction several decades ago. Recent mortality events in Eurasian collared doves in Arizona and Montana, USA, during the winter of 2009–2010 were the result of pigeon paramyxovirus (PPMV), a novel disease...
A low-cost method to measure the timing of post-fire flash floods and debris flows relative to rainfall
Jason W. Kean, Dennis M. Staley, Robert J. Leeper, Kevin Michael Schmidt, Joseph E. Gartner
2012, Water Resources Research (48)
Data on the specific timing of post-fire flash floods and debris flows are very limited. We describe a method to measure the response times of small burned watersheds to rainfall using a low-cost pressure transducer, which can be installed quickly after a fire. Although the pressure transducer is not designed...

2012, Environmental Science & Technology (46) 5824-5833
The functional gene diversity and structure of microbial communities in a shallow landfill leachate-contaminated aquifer were assessed using a comprehensive functional gene array (GeoChip 3.0). Water samples were obtained from eight wells at the same aquifer depth immediately below a municipal landfill or along the predominant downgradient groundwater flowpath. Functional...

William N. Batts, Andrew E. Goodwin, James R. Winton
2012, Journal of General Virology (93) 1247-1252
A bacilliform virus was isolated from diseased fathead minnows (Pimephales promelas). Analysis of the complete genome coding for the polyprotein (pp1ab), spike (S), membrane (M) and nucleocapsid (N) proteins revealed that the virus was most like white bream virus (WBV), another bacilliform virus isolated from white bream (Blicca bjoerkna L.) and...
Transcriptional profiling of the parr–smolt transformation in Atlantic salmon
Laura S. Robertson, Stephen D. McCormick
2012, Comparative Biochemistry and Physiology, Part D: Genomics and Proteomics (7) 351-360
The parr–smolt transformation in Atlantic salmon (Salmo salar) is a complex developmental process that culminates in the ability to migrate to and live in seawater. We used GRASP 16K cDNA microarrays to identify genes that are differentially expressed in the liver, gill, hypothalamus, pituitary, and olfactory rosettes of smolts compared...

Timothy P. O’Brien, William W. Taylor, Andrew S. Briggs, Edward F. Roseman
2012, Journal of Great Lakes Research (38) 776-785
Rainbow smelt are an important prey species for native and introduced salmonines in the Great Lakes. In Lake Huron, rainbow smelt populations are characterized by variable recruitment and year-class strength. To understand the influence of water temperature on reproduction, growth, and survival during larval-fish stages, we sampled spawning tributaries and...
Carbon dioxide stripping in aquaculture -- part II: development of gas transfer models
John Colt, Barnaby Watten, Tim Pfeiffer
2012, Aquacultural Engineering (47) 38-46
The basic mass transfer equation for gases such as oxygen and carbon dioxide can be derived from integration of the driving force equation. Because of the physical characteristics of the gas transfer processes, slightly different models are used for aerators tested under the non steady-state procedures, than for packed columns,...

Simulating the effect of climate extremes on groundwater flow through a lakebed
Makhan L. Virdi, Terrie M. Lee, Amy Swancar, Richard G. Niswonger
2012, Ground Water (51) 203-218
Groundwater exchanges with lakes resulting from cyclical wet and dry climate extremes maintain lake levels in the environment in ways that are not well understood, in part because they remain difficult to simulate. To better understand the atypical groundwater interactions with lakes caused by climatic extremes, an original conceptual approach...

Lisa H. Nowell, Amy S. Ludtke, David K. Mueller, Jonathon C. Scott
2012, Scientific Investigations Report 2012-5228
Beach water and sediment samples were collected along the Gulf of Mexico coast to assess differences in contaminant concentrations before and after landfall of Macondo-1 well oil released into the Gulf of Mexico from the sinking of the British Petroleum Corporation's Deepwater Horizon drilling platform. Samples were collected at 70...
Shipboard surveys track magnetic sources in marine sediments--geophysical studies of the Stono and North Edisto Inlets near Charleston, South Carolina
Anjana K. Shah, M. Scott Harris
2012, Open-File Report 2012-1112
Magnetic field data are traditionally used to analyze igneous and metamorphic rocks, but recent efforts have shown that magnetic sources within sediments may be detectable, suggesting new applications for high-resolution magnetic field surveys. Candidates for sedimentary sources include heavy mineral sand concentrations rich in magnetite or hematite, alteration-induced glauconite, or...
