Researchers say they have recognized a submerged mainland 66% the extent of Australia, and they are calling it Zealandia.

This recently proposed mainland is around 1.74 million square miles in size and 94 percent submerged. Be that as it may, at its most elevated focuses, it projects over the sea surface as New Zealand and New Caledonia, as per a paper distributed in GSA Today, the diary of the Geological Society of America.


The proposed acknowledgment of the mainland of Zealandia does not speak to the revelation of another land mass. Rather,the paper contends that the topographical confirmation recommends the land mass ought to be grouped not as an accumulation of islands and sections but rather as a true blue landmass.

“On the off chance that we could pull the fitting on the seas, it is clear to everybody we have mountain chains and a major, high-standing mainland over the sea hull,” Nick Mortimer, a geologist at GNS Science in Dunedin, New Zealand, told Reuters.

Mortimer was the lead creator of the paper, “Zealandia: Earth’s Hidden Continent.”

New revelations about the geography of the locale demonstrate what has for some time been suspected, he said.

“Since about the 1920s, every once in a while in geography papers individuals utilized “mainland” to depict different parts of New Zealand and the Catham Islands and New Caledonia,” Mortimer said.

“The distinction now is that we feel we’ve sufficiently accumulated data to change “mainland” to the thing ‘landmass,'” he included.

The land mass meets the topographical meaning of a landmass, as indicated by the paper. It has high height contrasted with the sea outside layer. It has certain topographical parts, including an outside thicker than sea hull. Furthermore, it has very much characterized confines around a range sufficiently huge to be viewed as a landmass as opposed to a part.

Zealandia is accepted to have split far from Australia around 80 million years back and sunk underneath the ocean as a feature of the separation of the super-landmass Gondwanaland.

By complexity, present day individuals are accepted to have developed just around 200,000 years prior.

Mortimer perceives that the paper now speaks to the making of a geographical case — the opening of a contention as opposed to its determination.

“The litmus test will truly be if Zealandia shows up in maps and chart books in five or 10 years time,” he said.
