Denmark Strait , which exploded with the loss of all but three of its 1,418 crew; was seriously damaged in the engagement. "Bismarck" entered the Atlantic through the Strait, but damage sustained in the battle—combined with British aircraft search-and-destroy missions—led to its sinking three days later. Denmark Strait The Denmark Strait () or Greenland Strait (, 'Greenland Sound') is an oceanic strait between Greenland (to its northwest) and Iceland (to its southeast). The Norwegian island of Jan Mayen lies northeast of the strait. The strait connects the Greenland Sea, an extension of the Arctic Ocean, to the Irminger Sea, a part of
Davis Strait Davis Strait 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 strike-slip faulting transferred plate-tectonic motions in the Labrador Sea to Baffin Bay. It is the world's broadest strait. 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. The strait is famous for its fierce tides that can range from , which discouraged many earlier explorers. US Geological Survey has
