Pacific Basins

The Canadian basins in the Pacific Ocean average a depth as deep as the CN Tower is tall!

The East Pacific Rise forms the seaward edge, while the Pacific Coastal Shelf forms the landward edge, of the East Pacific Basin. The Pacific Basin is a large and deep depression that gradually slopes towards the seafloor, forming the shape of a basin. There are two sub-basins that lie along Canada’s Pacific coast: the northern Hectate Strait is formed by a depression in the Queen Charlotte Continental Shelf, that ranges from 200 - 400 metres deep. This region is bounded by the coast of northern British Columbia, and the Queen Charlotte Islands. The more southern Strait of Georgia is formed in the Vancouver Island Shelf, and has an average depth of about 155 metres. This Strait lies in between Vancouver Island and the most southern point of British Columbia. The American coastal shelf is a large continental shelf that extends from the mainland of North and South America, steeply sloping towards the Pacific Ocean Floor.
