Scientists set sail to study 'lost 8th continent' Zealandia
Scientists from the International Ocean Discovery Program on Friday set sail to explore the "lost continent" of Zealandia, a huge underwater landmass east of Australia. Zealandia broke away from the Gondwana super-continent roughly 75 million years ago. Researchers said it should be considered a new continent as it was a distinct geological entity meeting the criteria applying to other continents.
