Scientists map Earth's 'lost 8th continent' Zealandia in detail

Scientists have mapped the "lost eighth continent" Zealandia in "unprecedented detail". GNS Science published the maps on an interactive website to let users explore virtually. The maps cover the shape of the ocean floor and Zealandia's tectonic profile. The continent, which has an area of nearly five million square kilometres, got submerged beneath the Pacific Ocean millions of years ago.
