Recently, the Coast Guard has been approached by the Smithsonian 

 Institution to assist In developing a module on the aquatic 

 nuisance threat for an upcoming exhibit on "Oceans In Peril". 

 The Coast Guard welcomes this opportunity and Is providing 

 educational materials and expertise. 



THE SHIPPING STUDY 



The Nonlndlgenous Aquatic Nuisance Prevention and Control Act 

 required the Coast Guard to conduct a Shipping Study to explore 

 the Impact of shipping on the Introduction of ballast water Into 

 ports other than on the Great Lakes. Conducted under the 

 direction of Dr. James Carlton of Williams College, Mystic, 

 Connecticut, this 400 plus page report Identifies ports that may 

 be at risk from aquatic nuisance species being transported by 

 ballast water. The report also recommends possible control 

 options. The report estimates that 11,507,000,000 gallons of 

 ballast water arrived In United States ports In 1991 with New 

 Orleans receiving the highest amount of total ballast. Virtually 

 all U.S. ports receive ballast water from throughout the world 

 and northern Europe and the Pacific rim are the major 

 contributors. The report Is currently In agency clearance In 

 preparation for forwarding to Congress.
