The expedition aimed to establish that the eastern section of seabed passing close to the Pole, known as the Lomonosov and Mendeleyev Ridges, is in fact an extension of Russia's landmass. The expedition came as several countries are trying to extend their rights over sections of the Arctic Ocean floor. Both Norway and Denmark are carrying out surveys to this end. Vladimir Putin made a speech on a nuclear icebreaker on 3 May 2007, urging greater efforts to secure Russia's "strategic, economic, scientific and defense interests" in the Arctic.
