A scientific mission is currently working on defining the borders of "Zealandia", or as it is known as "the lost continent", which lies below New Zealand and New Caledonia in the South Pacific.
Zealandia separated from the supercontinent "Gondwana" - which was composed of all the present-day continents of the world - 83 million years ago, according to the "Life Science" site.
With the exception of New Zealand and New Caledonia, which are considered the summit of the continent floating above the sea, most of this continent is now located at the bottom of the Pacific Ocean.
Zealandia, or Río-e-Maui, was granted a continental characterization in 2017, and since then scientists have been working on creating a map of the lost continent, of which 94 are underwater.
The research team spent 28 days aboard the "Falcour" to explore the area, mapping 14,285 square miles (37,000 square kilometers).
It is reported that, according to the US National Oceanic and Atmospheric Administration (NOAA), only about 10 percent of the seabed area on planet Earth has been mapped, using modern sonar.
