The Fram Strait is the deepest gateway to the Arctic Ocean located between Greenland in the West and Svalbard in the East, the latitudinal boundaries are roughly 81°N and 77°N. With depths up to 5.6 km (in the Molloy Deep) it is the only deep connection between the Arctic Ocean and the world ocean, namely into the Greenland Sea and the Norwegian Sea. Other gateways are the Barents Sea Opening (BSO), the Bering Strait and various small channels in the Canadian Arctic Archipelago. They are all shallower or narrower than Fram Strait.
