The latter basin is the deepest one of the Arctic Ocean and the geographic North Pole is located there.
The Eurasian Basin is bounded by Greenland, the Lomonosov Ridge, and the shelves of the Laptev Sea, Kara Sea and Barents Sea.
[1] Today, the Gakkel Ridge is the site of some of the slowest seafloor spreading on the Earth, with 10 mm/yr near the Fram Strait and 6 mm/yr near the Laptev Sea.
Initial opening of the Eurasian Basin is constrained by magnetic anomaly and geologic information to the Cenozoic: it was first created about 53 Million years ago by the spreading of the sea floor.
