Why is the Gulf of St. Lawrence unique?
The Gulf of St. Lawrence is similar to an inland sea with a distinct ecosystem, characterized by partial isolation from the North Atlantic, freshwater runoff from the land, a deep trough running along its length, seasonal ice, the presence of a cold intermediate layer, shallow depths, and high biological productivity and diversity. The distinct qualities of the physical and biological components of the Gulf combine to create its unique environment. This environment also governs how humans settle and use the resources within it. As a result, a wide variety of human activities occur within and adjacent to the Gulf of St. Lawrence. Many depend on its resources for their livelihood. The human environment of the Gulf is also unique. It is surrounded by five provinces of which populations are composed of Anglophones and Francophones and many First Nations, which create a wide array of culturally and socially distinct settlements.
