AbstractThe Laurentian Channel is a wide, deep, U-shaped, glacially-excavated, cross-shelf trough in Atlantic Canada. It extends NW-SE approximately 700 km from the mouth of the St Lawrence River, across the Gulf of St Lawrence and terminates at the edge of the continental shelf south of Newfoundland (Fig. 1a, e). The Laurentian Channel was a major conduit of ice-stream flow on the SE margin during several advances of the Laurentide Ice Sheet.
Summary(Plain Language Summary, not published)
The Laurentian Channel is a wide, deep, U-shaped, glacially-excavated, cross-shelf trough in Atlantic Canada that extends northwest-southeast approximately 700 km from the mouth of the St. Lawrence River, across the Gulf of St. Lawrence, and terminates at the edge of the continental shelf south of Newfoundland. The Laurentian Channel was a major conduit of glacier flow on the southeast margin of the Laurentide Ice Sheet.
