Celeste A. Journey, Karen M. Beaulieu, Rodney R. Knight, Jennifer L. Graham, Jane M. Arrington, Rebecca West, John Westcott, Paul M. Bradley
2010, Conference Paper, Proceedings of the 2010 South Carolina Water Resources Conference
Algal blooms can be harmful and a nuisance in a variety of aquatic ecosystems, including reservoirs and lakes. Cyanobacterial(blue-green algae) harmful algal blooms are notorious for producing both taste-and-odor compounds and potent toxins that may affect human health. Taste–and-odor episodes are aesthetic problems often caused by cyanobacterial-produced organic compounds (geosmin...

Extrapolating growth reductions in fish to changes in population extinction risks: Copper and Chinook salmon.
Christopher A. Mebane, David L. Arthaud
2010, Human and Ecological Risk Assessment (16) 1026-1065
Fish commonly respond to stress, including stress from chemical exposures, with reduced growth. However, the relevance to wild populations of subtle and sometimes transitory growth reductions may not be obvious. At low-level, sustained exposures, Cu is one substance that commonly causes reduced growth but little mortality in laboratory toxicity tests...
Map correlation method: Selection of a reference streamgage to estimate daily streamflow at ungaged catchments
Stacey A. Archfield, Richard M. Vogel
2010, Water Resources Research (46)
Daily streamflow time series are critical to a very broad range of hydrologic problems. Whereas daily streamflow time series are readily obtained from gaged catchments, streamflow information is commonly needed at catchments for which no measured streamflow information exists. At ungaged catchments, methods to estimate daily streamflow time series typically...

Bret A. Robinson
2010, Scientific Investigations Report 2010-5157
In recent years carbon dioxide intrusion has become recognized as a potentially serious health threat where homes are constructed on or near reclaimed surface coal mines. When carbon dioxide invades the living space of a home, it can collect near the floor, displace the oxygen there, and produce an oxygen-deficient...

Monitoring and assessment of ocean acidification in the Arctic Ocean-A scoping paper
Lisa L. Robbins, Kimberly K. Yates, Richard Feely, Victoria Fabry
2010, Open-File Report 2010-1227
Carbon dioxide (CO2) in the atmosphere is absorbed at the ocean surface by reacting with seawater to form a weak, naturally occurring acid called carbonic acid. As atmospheric carbon dioxide increases, the concentration of carbonic acid in seawater also increases, causing a decrease in ocean pH and carbonate mineral saturation...
