The Arctic Ocean is not a single basin; rather, it is divided by the Lomonosov Ridge into two primary deep basins: the Eurasia Basin and the Amerasia Basin.1
Within these, the largest subbasin of the Arctic Ocean is the Canada Basin. It extends approximately 700 miles from the Beaufort Shelf to the Alpha Cordillera and features an average depth of 12,500 feet.1
