A map showing the topography of Zealandia. There is still much unknown about the continent and whether the discovery of Zealandia could change historical climate models. Data for the bathymetric map was provided by the Seabed2030 project — a global effort to map the entire ocean floor by 2030. Scientists say they have identified an underwater continent two-thirds the size of Australia — and they are calling it Zealandia. Zealandia continent lost underwater.

Zealandia: Unprecedented Maps of Earth’s 8th Sunken Continent Reveal a Never-Before-Seen World Earth has eight continents, and you probably never heard about the 8th. The motions of the plates that caused Zealandia to sink continue to shape the underwater geology of the region into sunken regions called grabens and basins. "Their value is that they provide a fresh context in which to explain and understand the setting of New Zealand's volcanoes, plate boundary and sedimentary basins. Today, 94 per cent of Zealandia lies underwater – if we drained the oceans, we could see it unfurling some 4.9 million sq km across the South Pacific. Image Credit: Wikimedia Commons / Public Domain.
