Concern is mounting regarding the human health and environmental effects of bisphenol A (BPA), a high-production-volume chemical used in synthesis of plastics. We have reviewed the growing literature on effects of low doses of BPA, below 50 mg/(kg day), in laboratory exposures with mammalian model organisms. Many, but not all, effects of...

2007, Condor (109) 199-205
We investigated the occurrence and potential ecotoxicological significance of elevated concentrations of strontium (Sr) in eggshells of nine passerine birds from four regions in Arizona. Concentrations of Sr in eggshells ranged from 70 to 1360 µg g−1 dry weight (overall mean = 684 ± 345 SD µg g−1 dw) for the four...
GIS for the Gulf: A reference database for hurricane-affected areas
Dave Greenlee
2007, Circular 1306-4C
A week after Hurricane Katrina made landfall in Louisiana, a collaboration among multiple organizations began building a database called the Geographic Information System for the Gulf, shortened to "GIS for the Gulf," to support the geospatial data needs of people in the hurricane-affected area. Data were gathered from diverse sources...
Restoring resilience to the Gulf of Mexico coast
Gregory J. Smith
2007, Circular 1306-1A
Hurricane Katrina and its destructive aftermath in 2005 were unprecedented. Hurricanes Dennis, Rita, and Wilma were also powerful hurricanes affecting the Gulf of Mexico that year. These storms highlighted the need to integrate science that supports restoration of natural landscapes with intelligent coastal planning. The following essay describes both the...

Water quality of Lake Pontchartrain and outlets to the Gulf of Mexico following Hurricanes Katrina and Rita: Chapter 7E in Science and the storms-the USGS response to the hurricanes of 2005
Stanley C. Skrobialowski, W. Reed Green, Joel M. Galloway
2007, Circular 1306-7E
Water-quality samples collected from drainage canals, from Lake Pontchartrain, La., and from flood waters contained contaminants typically found in waters influenced by urban runoff. Pesticides and wastewater compounds were detected in all water samples, but none exceeded U.S. Environmental Protection Agency (EPA) drinking water or aquatic life criteria. Although metals...
Monitoring Hurricane Rita Inland Storm Surge
Benton D. McGee, Roland W. Tollett, Burl B. Goree
2007, Circular 1306-7J
Pressure transducers (sensors) are accurate, reliable, and cost-effective tools to measure and record the magnitude, extent, and timing of hurricane storm surge. Sensors record storm-surge peaks more accurately and reliably than do high-water marks. Data collected by sensors may be used in storm-surge models to estimate when, where, and to...
Pattern and potential causes of White-faced Ibis, Plegadis chihi, establishment in the northern prairie and parkland region of North America

2007, Canadian Field-Naturalist (121) 46-56
The Northern Prairie and Parkland Waterbird Conservation Plan calls for renewed attention to determining the current status of waterbird populations, their distributions, and conservation needs. It highlights the need for baseline information on the White-faced Ibis (Plegadis chihi). In response, we examined the historical and current distribution of the ibis...

2007, FEMS Microbiology Ecology (60) 85-97
The identity of the numerically dominant N2-fixing bacteria in biological soil crusts of the Colorado Plateau region and two outlying areas was determined using multiple approaches, to link the environmental diversity of nifH gene sequences to cultured bacterial isolates from the regions. Of the nifH sequence-types detected in soil crusts...
Potential consequences of saltwater intrusion associated with Hurricanes Katrina and Rita
Gregory D. Steyer, Brian C. Perez, Sarai C. Piazza, Glenn Suir
2007, Circular 1306-6C
Hurricanes Katrina and Rita pushed salt water from the Gulf of Mexico well inland into freshwater marsh communities in coastal Louisiana. This paper describes the spatial extent of saltwater intrusion and provides an initial assessment of impacts (salt stress) to coastal marsh vegetation communities....
Data access and dissemination for emergency response and long-term recovery efforts related to Hurricanes Katrina and Rita
Scott Wilson, Chris Cretini
2007, Circular 1306-4B
The U.S. Geological Survey's (USGS) National Wetlands Research Center (NWRC) responded to Hurricanes Katrina and Rita by providing geospatial support to Federal, State, and local partners. The NWRC used its data and information management systems to deliver aerial photography and maps to emergency responders in a time of critical need....

Trends of brominated diphenyl ethers in fresh and archived Great Lakes fish (1979-2005)
Stuart Batterman, Sergei Chernyak, Erica Gwynn, David Cantonwine, Chunrong Jia, Linda J. Begnoche, James P. Hickey
2007, Chemosphere (69) 444-457
While few environmental measurements of brominated diphenyl ethers (BDEs) were completed prior to the mid-1990s, analysis of appropriately archived samples might enable the determination of contaminant trends back to the introduction of these chemicals. In this paper, we first investigate the stability of BDEs in archived frozen and extracted fish...

2007, Journal of Geophysical Research B: Solid Earth (112)
[1] A new three-dimensional P wave velocity model for the greater San Francisco Bay region has been derived using the double-difference seismic tomography method, using data from about 5,500 chemical explosions or air gun blasts and approximately 6,000 earthquakes. The model region covers 140 km NE-SW by 240...
Multiple-methods investigation of recharge at a humid-region fractured rock site, Pennsylvania, USA
C.S. Heppner, J. R. Nimmo, G.J. Folmar, W.J. Gburek, D. W. Risser
2007, Hydrogeology Journal (15) 915-927
Lysimeter-percolate and well-hydrograph analyses were combined to evaluate recharge for the Masser Recharge Site (central Pennsylvania, USA). In humid regions, aquifer recharge through an unconfined low-porosity fractured-rock aquifer can cause large magnitude water-table fluctuations over short time scales. The unsaturated hydraulic characteristics of the subsurface porous...

2007, Conference Paper, Proceedings of SPIE - The International Society for Optical Engineering
The dynamics of rainstorm plumes in the coastal waters of southern California was studied during the Bight'03 Regional Water Quality Program surveys. Measurements of surface salinity and bacterial counts collected from research vessels were compared to MODIS-Aqua satellite imagery. The spectra of normalized water-leaving radiation (nLw) were different in plumes...
