NOAA & Smithsonian Say U.S. Waters Safer from Invasive Species If Ships Flush and Fill Ballast Water at Sea (Sep 24, 2007) DOC. National Oceanic and Atmospheric Administration.
The technical report released finds ship captains can dramatically reduce the supply of invasive aquatic species delivered to U.S. ports, if they flush and refill ballast tanks with ocean water before arrival. The report describes the effectiveness of ballast water exchange procedures as a way to reduce aquatic invasive species discharged into U.S. waters, including the Great Lakes and Chesapeake Bay.
