What is the name of the strait connecting Baffin Bay to the Labrador Sea?

The strait connecting Baffin Bay to the Labrador Sea is the Davis Strait.

Davis Strait lies between Greenland and Baffin Island in Nunavut, Canada. It forms the southern outlet of Baffin Bay and opens southward into the Labrador Sea, making it an important link between Arctic waters and the North Atlantic.

The strait is named for English explorer John Davis, who sailed in the region during attempts to find a Northwest Passage in the late 16th century. By the 17th century, the waters had also become associated with commercial whaling. Geologically, the strait contains buried basins and ridges created by ancient faulting and plate movements.

Davis Strait is comparatively shallow in places because of the Davis Sill, an underwater ridge between Greenland and Baffin Island. That sill influences the movement of deep water between the Labrador Sea and Baffin Bay. The region is also known for sea ice, strong currents, severe weather, and biologically rich Arctic marine habitats.

Hudson Strait is a different passage: it connects Hudson Bay with the Labrador Sea, farther southwest.
