Disko Bay Disko Bay Disko Bay (; ) is a bay on the western coast of Greenland. The bay constitutes a wide southeastern inlet of Baffin Bay. To the south the coastline is complicated with multiple waterways of skerries and small islands in the Aasiaat archipelago. Qasigiannguit and Ilimanaq are the main settlements in the southeastern inlet, just south of the outflow of Ilulissat Icefjord. From the north the bay is bounded by Qeqertarsuaq, the largest island on the western coast. North of Ilulissat and west of Aluttoq Island the bay transforms into Sullorsuaq Strait separating Qeqertarsuaq from Nuussuaq Peninsula. It is
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
