Geography and Geology
See also: Jakobshavn IsbræBaffin Bay is an arm of the Atlantic Ocean bounded by the Baffin Island in the west, Greenland in the east, and Ellesmere Island in the north. It connects to the Atlantic through the Davis Strait, and to the Arctic through several narrow channels of Nares Strait. It is a northwestern extension of the North Atlantic and Labrador Sea. It can also be viewed as a long strait separating Baffin Island and Greenland.
The bay is less than 1,000 m (3,300 ft) deep near the coast, where the sea bottom is covered with gravel, crushed stone and sand. In the center, there is a deep pit called Baffin Hollow reaching 2,136 m (7,008 ft) (see depth map), which is mostly covered in silt. Currents form a cyclonic circulation. On the eastern periphery, in summer, the West Greenland Current transports water from the Atlantic Ocean to the North. In its western part, the Baffin Island Current brings the Arctic waters to the south.

Famous quotes containing the words geography and and/or geography:
“The totality of our so-called knowledge or beliefs, from the most casual matters of geography and history to the profoundest laws of atomic physics or even of pure mathematics and logic, is a man-made fabric which impinges on experience only along the edges. Or, to change the figure, total science is like a field of force whose boundary conditions are experience.”
—Willard Van Orman Quine (b. 1908)
“Ktaadn, near which we were to pass the next day, is said to mean “Highest Land.” So much geography is there in their names.”
—Henry David Thoreau (1817–1862)
