The Arctic Basin Marine Ecozone, as defined by the Commission for Environmental Cooperation (CEC), is a Canadian marine ecozone encompassing the northwestern areas of waters on the Arctic continental shelf.

Polar nights and the midnight sun may last months in this region, which has come to characterize the stereotype of the north.

All human activity here involves scientific excursions, petroleum exploration,[3] rare hunting groups and extreme adventurers.

[4] Ice floes that are kilometres long and several metres thick are common in this Arctic Ocean ecozone.

[3] Undersea, the dominant feature is the deep Canada Basin, extending from the Beaufort Sea to the North Pole to depths reaching 3,600 m.[2] The Lomonosov Ridge represents its northern submarine extent.
