Ice in the Davis Strait65.5N 57W
As northern hemisphere temperatures warm up, sea ice breaks apart and melts in the Davis Strait, which lies between mid-western Greenland (upper right) and Baffin Island in the Canadian territory of Nunavut (left).
With a water depth of between one and two thousand meters the strait is substantially shallower than the Labrador Sea to the south or Baffin Bay to the north.
It is underlain by complex geological features of buried grabens (basins) and ridges, probably formed by strike-slip faulting during Paleogene times about 45 million to 62 million years ago.
The strait is famous for its fierce tides, which can range from 30 to 60 feet, and discouraged many earlier explorers.
