Ballast water - water carried in tanks on ships to help provide stability and aid steering - is likely the single greatest source for introduction of non-native and invasive aquatic species. Ballast water is collected in one body of water and discharged into another body of water, usually large distances apart. At least one new invasive species is found in the Great Lakes every year, with Lake Superior being particularly at risk. Scientists from the U.S.
This project will provide a protocol for prioritizing sites in the St. Louis Area of Concern (AOC ) for restoration based on site-specific bioavailability considerations. Despite large data collection efforts focused on sediment chemistry, the extent to which sediment with moderate levels of contamination is available for uptake into biota and therefore contributing to Beneficial Use Impairments (BUI)s is still largely unknown.
This project will collect real-time parameter data for specific conductance, water temperature, pH, dissolved oxygen, turbidity and stream flow at the United States geological Survey (USGS) gaging stations located at Fargo, ND and Grand Forks, ND on the Red River of the North; and publish the data both on the USGS NWIS website and in the USGS Annual Report.
