Charles J. Henny, Robert A. Grove, James L. Kaiser, Branden L. Johnson, Chad V. Furl, Robert J. Letcher
2011, Ecotoxicology (20) 682-697
Several polybrominated biphenyl ether (PBDE) congeners were found in all 175 osprey (Pandion haliaetus) eggs collected from the Columbia River Basin between 2002 and 2009. ΣPBDE concentrations in 2008–2009 were highest in osprey eggs from the two lowest flow rivers studied; however, each river flowed through relatively large and populous...

David A.V. Eckhardt, John H. Williams, J. Alton Anderson
2011, Open-File Report 2011-1319
Geophysical logs were collected and analyzed along with bedrock core samples and bedrock outcrops to define the bedrock stratigraphy and flow zones penetrated by 93 monitor and water-supply wells in Cayuga County, New York. The work was completed from 2001 through 2011 as part of an investigation of volatile-organic compound...

William R. Gascoigne, Dana Hoag, Lynne Koontz, Brian A. Tangen, Terry L. Shaffer, Robert A. Gleason
2011, Ecological Economics (70) 1715-1725
This study uses biophysical values derived for the Prairie Pothole Region (PPR) of North and South Dakota, in conjunction with value transfer methods, to assess environmental and economic tradeoffs under different policy-relevant land-use scenarios over a 20-year period. The ecosystem service valuation is carried out by comparing the biophysical and...

Colleen E. Rostad, Christopher J. Schmitt, John G. Schumacher, Thomas J. Leiker
2011, Water, Air, & Soil Pollution (217) 431-443
Surface water samples were collected in 2006 from a lead mine-mill complex in Missouri to investigate possible organic compounds coming from the milling process. Water samples contained relatively high concentrations of dissolved organic carbon (DOC; greater than 20 mg/l) for surface waters but were colorless, implying a lack of naturally...
Variability of albedo and utility of the MODIS albedo product in forested wetlands
David M. Sumner, Qinglong Wu, Chandra S. Pathak
2011, Wetlands (31) 229-237
Albedo was monitored over a two-year period (beginning April 2008) at three forested wetland sites in Florida, USA using up- and down-ward facing pyranometers. Water level, above and below land surface, is the primary control on the temporal variability of daily albedo. Relatively low reflectivity of water accounts for the...

2011, Open-File Report 2011-1315
In 2010, the U.S. Geological Survey (USGS), Pacific Coastal and Marine Science Center completed three cruises to map the bathymetry of the main channel and shallow intertidal mudflats in the southernmost part of south San Francisco Bay. The three surveys were merged to generate comprehensive maps of Coyote Creek (from...
Changes in low-flow frequency from 1976-2006 at selected streamgages in New York, excluding Long Island
Thomas P. Suro, Christopher L. Gazoorian
2011, Scientific Investigations Report 2011-5112
Many Federal, State, and local agencies use low-flow data to establish water-use policy and help determine the total maximum daily loads and effluent limits of point and nonpoint sources of contamination of surface water during periods of decreased streamflow. Low-flow magnitude and frequency are used often by water-supply planners, reservoir...
Use of upscaled elevation and surface roughness data in two-dimensional surface water models
J.D. Hughes, J.D. Decker, C.D. Langevin
2011, Advances in Water Resources (34) 1151-1164
In this paper, we present an approach that uses a combination of cell-block- and cell-face-averaging of high-resolution cell elevation and roughness data to upscale hydraulic parameters and accurately simulate surface water flow in relatively low-resolution numerical models. The method developed allows channelized features that preferentially connect large-scale grid cells at...

2011, Science of the Total Environment (410-411) 248-257
We surveyed four Chesapeake Bay tributaries for skin and liver tumors in brown bullhead (Ameiurus nebulosus). We focused on the South River, where the highest skin tumor prevalence (53%) in the Bay watershed had been reported. The objectives were to 1) compare tumor prevalence with nearby rivers (Severn and Rhode)...

Katharina Pfaff, Alan Koenig, Thomas Wenzel, Ian Ridley, Ludwig H. Hildebrandt, David L. Leach, Gregor Markl
2011, Chemical Geology (286) 118-134
Various models have been proposed to explain the formation mechanism of colloform sphalerite, but the origin is still under debate. In order to decipher influences on trace element incorporation and sulfur isotope composition, crystalline and colloform sphalerite from the carbonate-hosted Mississippi-Valley Type (MVT) deposit near Wiesloch, SW Germany, were investigated...

Joseph N. Mwangi, Ning Wang, Andrew Ritts, James L. Kunz, Christopher G. Ingersoll, Hao Li, Baolin Deng
2011, Environmental Toxicology and Chemistry (30) 981-987
Silicon carbide nanowires (SiCNW) are insoluble in water. When released into an aquatic environment, SiCNW would likely accumulate in sediment. The objective of this study was to assess the toxicity of SiCNW to four freshwater sediment-dwelling organisms: amphipods (Hyalella azteca), midges (Chironomus dilutus), oligochaetes (Lumbriculus variegatus), and mussels (Lampsilis siliquoidea)....

2011, Transactions of the ASABE (54) 1269-1279
The use of pond ash (fly ash that has been placed in evaporative ponds for storage and subsequently dewatered) for feedlot surfaces provides a drier environment for livestock and furnishes economic benefits. However, pond ash is known to have high concentrations of trace elements, and the runoff water-quality effects of...
National Acid Precipitation Assessment Program Report to Congress: An integrated assessment
Douglas A. Burns, Mark E. Fenn, Jill Baron, Jason A. Lynch, Bernard J. Cosby
2011, Report
Acid deposition, more commonly known as acid rain, occurs when emissions of sulfur dioxide (SO2) and nitrogen oxides (NOx) react in the atmosphere with water, oxygen, and oxidants to form various acidic compounds. Prevailing winds transport the acidic compounds hundreds of miles, often across state and national borders. These acidic...

India is an important non-breeding ground for migratory waterfowl in the Central Asian Flyway. Millions of birds visit wetlands across the country, yet information on their distribution, abundance, and use of resources is rudimentary at best. Limited information suggests that populations of several species of migratory ducks are declining due...
Serum amyloid A (SAA) as a biomarker of chronic infection due to boat strike trauma in a free-ranging Florida manatee (Trichechus manatus latirostris) with incidental polycystic kidneys
Kendal E. Harr, Renee Rember, Pamela E. Ginn, Jessica Lightsey, Martha Keller, James Reid, Robert K. Bonde
2011, Journal of Wildlife Diseases (47) 1026-1031
Watercraft-related trauma is the predominant cause of human-induced mortality in manatees (Trichechus manatus latirostris), a federal- and state-listed endangered species. Pyothorax (documented in this case report) and other secondary infections are common sequelae of inhalation of water and the open wounds caused by boat propellers. These secondary infections can lead...
