Island group, northern Canada.
Part of the Canadian Arctic archipelago, it comprises all the islands north of latitude 74k30′ N, including the Parry and Sverdrup island groups. The islands, the largest of which are Melville , Devon, and Axel Heiberg, have a total land area of over 150,000 sq mi (390,000 sq km). Probably first visited by the Vikings с AD 1000, they were partially explored (1615–16) by English navigators William Baffin and Robert Bylot. The islands, which are administratively split between the Northwest Territories and Nunavut , were named in 1953 to honour Queen Elizabeth II .
