The 6 countries shaded; the smallest are dots.

The Arctic is the smallest and shallowest of the world’s oceans, about 14 million km², and much of it is covered by sea ice, thickest in winter and thinnest in September. The ice has shrunk sharply since satellite records began in 1979, and the summer Arctic may be almost ice-free within decades.

As the ice retreats, shipping routes along the coasts of Russia and Canada, and the oil, gas and fish of the Arctic, are becoming easier to reach. Five countries, the Arctic Five, ring the ocean, and they agreed in 2008 that the law of the sea, not a new treaty, would settle their claims to its seabed.

The Arctic Five5

  • Flag of Russia
    Russia

    Has about half of the ocean’s coastline. It planted a flag on the seabed at the North Pole in 2007, and claims much of the seabed along the Lomonosov Ridge.

  • Flag of Canada
    Canada

    Its Arctic Archipelago holds the Northwest Passage, which Canada counts as its own waters and others as an international strait.

  • Flag of United States

    Through Alaska’s north coast, on the Beaufort and Chukchi Seas.

  • Flag of Denmark

    Through Greenland, whose Cape Morris Jesup is one of the northernmost points of land on Earth.

  • Flag of Norway
    Norway

    Its northern coast and the Svalbard islands face the Barents Sea. Warm Atlantic water keeps its ports free of ice all year.

The sixth1

  • Flag of Iceland
    Iceland

    Its north coast faces the Greenland Sea, which is often counted as part of the Arctic Ocean. The Arctic Circle touches only its island of Grímsey.

Close calls

Finland and Sweden

Both reach well north of the Arctic Circle and are on the Arctic Council, but neither has an Arctic Ocean coast: Norway and Russia lie between them and the sea.

Where the ocean ends

The line between the Arctic and the Atlantic is drawn differently by different bodies. Counted narrowly, it passes north of Iceland, which is why Iceland is sometimes left off the list.
