500 |a"Risks for the introduction of nonindigenous marine species into the Estuary and Gulf of St. Lawrence (EGSL) by foreign commercial shipping activities were evaluated by conducting three different surveys to characterize 1) the vessel traffic of foreign origin in the EGSL, 2) ballasting operations of foreign vessels entering ports of the EGSL, and 3) the biodiversity and species richness of protistan and meta-zoan taxa found in ballast water and sediment of incoming foreign vessels."--Page ix.
