Canadian Arctic Archipelago72.6N 99.4W
The Canadian Arctic Archipelago is an archipelago north of the Canadian mainland in the Arctic. Covering about 1,424,500 km2 (550,000 sq mi), this group of 36,563 islands comprises most of the territory of Nunavut and part of that of the Northwest Territories.
The archipelago extends some 2,400 km (1,500 mi) longitudinally and 1,900 km (1,200 mi) from the mainland to Cape Columbia, the northernmost point on Ellesmere Island.
It is bounded on the west by the Beaufort Sea; on the northwest by the Arctic Ocean; on the east by Greenland, Baffin Bay and Davis Strait; and on the south by Hudson Bay and the Canadian mainland.
The various islands are separated from each other and the continental mainland by a series of waterways collectively known as the Northwestern Passages. Here, most of such waterways are covered by ice, which appears to be cracking with the warmer summer temperatures.
