In 2014 Denmark made a submission that the Lomonosov Ridge is a natural prolongation of the Greenland landmass, and that it constitutes a submarine elevation the Greenland continental shelf will extend beyond the North Pole.

The global mid-ocean ridge system is the most extensive magmatic system on our planet and is the site of 75 per cent of Earth’s volcanism – Nature August 2019 . A US sonar survey in 2001 rev...
