Baffin Bay separates Baffin Island from which land mass?

Baffin Bay, 689 000 km2 (266.064 sq miles), is a deep body of water located between Greenland and Baffin Island. Water depths are generally less than 1,000 m (0.6 miles), but reach a maximum 2,400 m (1.45 miles) near its centre. The bay is connected to the Arctic Ocean in the north through Nares Strait, Jones and Lancaster sounds, and to the Labrador Sea in the south by Davis Strait.

At the northern end of the bay, Canada's largest polynya, an area of open water surrounded by sea ice, provides an overwintering ground for belugas, walruses and narwhals. This polynya, the North Water, is an oasis of biological productivity in the spring and supports immense nesting populations of seabirds.

Fishing began in the bay as early as 1650, and by 1900 intensive fishing by Europeans and Americans had depleted the bay's large whale population.
