Lurking underneath New Zealand is a long-hidden continent referred to as Zealandia, geologists say. However since no one is in control of formally designating a brand new continent, person scientists will in the end have to pass judgement on for themselves.
A crew of geologists pitches the medical case for the brand new continent within the March/April factor of GSA As of late, arguing that Zealandia is a continual expanse of continental crust overlaying round four.nine million sq. kilometers. That’s concerning the measurement of the Indian subcontinent. In contrast to the opposite most commonly dry continents, round 94 % of Zealandia hides underneath the sea. Best New Zealand, New Caledonia and a couple of small islands peek above the waves.
“If lets pull the plug at the international’s oceans, it might be moderately transparent that Zealandia stands proud about three,000 meters above the encircling ocean crust,” says find out about coauthor Nick Mortimer, a geologist at GNS Science in Dunedin, New Zealand. “If it wasn’t for the sea degree, way back we’d have known Zealandia for what it was once — a continent.”
The landmass faces an uphill fight for continent standing, regardless that. In contrast to planets and slices of geologic time (SN: 10/15/16, p. 14), no world panel exists to formally rubber-stamp a brand new continent. The present collection of continents is already obscure — generally given as six or seven, with geologists regarding Europe and Asia jointly as Eurasia. Proponents will simply have to start out the use of the time period “Zealandia” and hope it catches on, Mortimer says.

A landmass referred to as Zealandia (grey area) merits to enroll in the ranks of continents, geologists suggest. Whilst most effective 6 % of Zealandia rises above sea degree (darkish grey), together with New Zealand, swaths…
