Laurentian Channel

Beneath the Gulf of St. Lawrence, the Laurentian Channel forms a great submarine valley stretching from the Atlantic shelf towards the mouth of the Saguenay River. Its deep waters pass through Cabot Strait between Newfoundland and Cape Breton, with shallower fishing banks on either side. Ocean water moves inland along the trench beneath the fresher surface outflow. Cod gather at its edges, while sea pens and other creatures live on the deep channel floor.
