Lying north of mainland Canada, the Arctic Archipelago consists of 94 major islands (greater than 130 km2) and 36,469 minor islands covering a total of 1.4 million km2. Apart from Greenland, which is almost entirely ice covered, the Canadian Arctic Archipelago forms the world's largest High Arctic land area.
Balaklava Island, 8 km2, situated off the N coast of Vancouver Island, is located between Nigel and Hurst islands, and is flanked by Queen Charlotte Str in the N and Goletas Channel in the S. It is 15 km NW of Port Hardy, BC. This tiny island has a lighthouse at Scarlett Pt (1905) to aid shipping.
Circulation is generally anticlockwise; off Greenland, relatively warm, salty water moves north, while along Baffin Island, cold, fresher water originating from the Arctic Ocean flows south. Icebergs, formed by calving off the Greenland glaciers, appear year-round, but are most numerous in August.
The Haida Gwaii include about 150 islands in a scimitar-shaped archipelago 250 km long. Graham and Moresby Islands comprise the bulk of the 10 000 km2 area. Separated by 48-140 km of open water (Hecate Strait) from the mainland islands, the Haida Gwaii are among the most isolated islands in Canada.
