Davis Strait lies between mid-Western Greenland and the Canadian island of Baffin Island. Water depths in Davis Strait, at around 1-2 kilometres, are substantially less than in Labrador Sea to the south and Baffin Bay to the north. Davis Strait is underlain by complex geological features of buried basins and ridges, probably formed by strike-slip faulting during Palaeogene times about 45-62 million years ago. The strike-slip faulting transferred plate-tectonic motions in Labrador Sea to Baffin Bay.
