Total dissolved gas and water temperature in the lower Columbia River, Oregon and Washington, 2008: Quality-assurance data and comparison to water-quality standards
Dwight Q. Tanner, Heather M. Bragg, Matthew W. Johnston
2008, Open-File Report 2008-1357
Significant Findings When water is released through the spillways of dams, air is entrained in the water, increasing the downstream concentration of dissolved gases. Excess dissolved-gas concentrations can have adverse effects on freshwater aquatic life. The U.S. Geological Survey (USGS), in cooperation with the U.S. Army Corps of Engineers, collected...

Faith A. Fitzpatrick, Marie C. Peppler, John F. Walker, William J. Rose, Robert J. Waschbusch, James L. Kennedy
2008, Scientific Investigations Report 2008-5235
In June 2008, heavy rain caused severe flooding across southern Wisconsin. The floods were aggravated by saturated soils that persisted from unusually wet antecedent conditions from a combination of floods in August 2007, more than 100 inches of snow in winter 2007-08, and moist conditions in spring 2008. The flooding...

Non-random temporary emigration and the robust design: Conditions for bias at the end of a time series: Section VIII
Catherine A. Langtimm
2008, Book chapter, Modeling demographic processes in marked populations
Deviations from model assumptions in the application of capture–recapture models to real life situations can introduce unknown bias. Understanding the type and magnitude of bias under these conditions is important to interpreting model results. In a robust design analysis of long-term photo-documented sighting histories of the endangered Florida manatee,...

Slowing of coastal subsidence is good news for restoration of Louisiana's wetlands
Matthew Cimitile, Helen Gibbons
2008, Sound Waves: Coastal science and research news from across the USGS
Every year, volunteers use thousands of discarded Christmas trees to build brush fences in the coastal waters of Louisiana. The fences slow down waves and trap sediment, allowing aquatic vegetation to take root in the still water and stimulating the growth of new marsh. This is one of many efforts...
