The cold Labrador current descends from the Arctic, bringing its chill to the Atlantic provinces
The cold Labrador Current flows from the Arctic, southward along the Labrador Coast. Some of the cold water from this current enters the Gulf of St. Lawrence, but the most of the water continues to move south, dividing into two arms. One of these arms, the cold inshore current, moves along the southern coast of Newfoundland, dipping around the edge of the province to enter the Gulf of St. Lawrence. The rest of the inshore branch of this current continues south and contributes to the Nova Scotia Current. The offshore branch of the Labrador Current is slightly warmer, and is responsible for the movement of pack ice and icebergs around the Grand Banks.
