Putin lays claim to enormous swath of North Pole

Russia is using new evidence gathered recently in order to justify a claim of 460,000 square feet of the North Pole.

A UN convention says no one can claim jurisdiction over the Arctic seabed because the geological structure does not match the surrounding continental shelves.

But Russian scientists have returned from a six-week mission on a nuclear ice-breaker to claim that the 1,220-mile long underwater Lomonosov Ridge is geologically linked to the Siberian continental platform – and similar in structure.
