Arctic realm

The Arctic realm is one of the planet's twelve marine realms, as designated by the WWF and Nature Conservancy. It includes the coastal regions and continental shelves of the Arctic Ocean and adjacent seas, including the Arctic Archipelago, Hudson Bay, and the Labrador Sea of northern Canada, the seas surrounding Greenland, the northern and eastern coasts of Iceland, and the eastern Bering Sea.

The Arctic realm transitions to the Temperate Northern Atlantic realm in the Atlantic Basin, and the Temperate Northern Pacific realm in the Pacific Basin.
