Submerged continent

A submerged continent or sunken continent is a region of continental crust, extensive in size but mainly undersea. The terminology is used by some paleogeologists and geographers in reference to some landmasses (none of which is as large as any of the generally recognized continents).

The definition of this term is unclear. If continental fragments and microcontinents smaller than 2,500,000 km2 (970,000 sq mi), which is approx. one third of the area of mainland Australia, are excluded, then Zealandia (approx. 4,900,000 km2 (1,900,000 sq mi)) would be the only geological feature which can be classified as a submerged continent.

Other notable submerged landmasses include Beringia, Doggerland, the Kerguelen Plateau, Mauritia, Sahul, and Sunda.

Submerged continents have been sought and speculated about in regard to a possible "lost continent" underwater in the Atlantic Ocean.[1][2] There was also a search in the 1930s for Lemuria, thought to have been a submerged continent between the Indian and African coasts.[3]
