Canadian Coast Guard Boosts Marine Survey Activities

摘要

The St. Lawrence River, the busy North American waterway that flows 3,800 kilometres to connect the Great Lakes to the Atlantic Ocean, is a vital component of the commerce and economy of Canada and the United States. Some 36 million metric tons of cargo moved through the Montreal-Lake Ontario section of the river in the nine-month navigation season of 1999, while the US locks at Messina, New York, saw nearly 3,167 vessel transits during the same period.
