Zealandia is a mostly submerged microcontinent about 3,500,000 km 2 (1,350,000 mi 2) in extent, larger than India or Greenland and just under half the size of Australia.The 7% of the continent that is above water makes up the two islands of New Zealand. It's almost all under water, but Zealandia should be considered a continent, say researchers. GNS Science. Today, this eighth continent is 93 percent underwater, so unless you’re a mermaid the only way to see it is by heading to the South Pacific and visiting the unique islands, separated by vast oceans but connected beneath the seas, that make up the remaining visible part of Zealandia. Zealandia broke off from Antarctica about 100 million years ago, and then from Australia about 80 million years ago. The new eighth continent – Zealandia, fulfills the definition of a continent. The concept of Zealandia isn't new. That’s about the size of the Indian subcontinent. physics, biology, astronomy, chemistry, and futurism. A new report published by the journal of the Geological Society of America recommends recognising the 4,900,000km2 sunken land mass of Zealandia – of which the islands of New Zealand and New Caledonia are the principle exposed features – as a fully independent continent, separate from Australia, Antarctica or any other neighbours. Michael is a longtime wiseGEEK contributor who specializes in topics relating to paleontology, WHY SHOULD ZEALANDIA BE CONSIDERED AS A CONTINENT? It was discovered using satellite mapping. Zealandia lies on the boundary between two tectonic plates, the Australian plate and the Pacific plate. Want to access Geographical on your tablet or smartphone? A new report published by the journal of the Geological Society of America recommends recognising the 4,900,000km 2 sunken land mass of Zealandia – of which the islands of New Zealand and New Caledonia are the principle exposed features – as a fully independent continent, separate from Australia, Antarctica or any other neighbours.. And that is even with counting the underwater area of Zealandia. It includes land that is mostly submerged, but during ice ages, was above sea level. Central America and New Zealand are recognised as continents, the latter being nine-tenths submerged, and there are four microcontinents: Rockall, Seychelles, Agulhas, and Jan Mayen.’, Spatial limits of Zealandia. It has variously been described as a submerged continent, a continental fragment, a microcontinent, and a continent. Having this said, there are only four continents, America, Afro-Eurasia, Australia, and Antarctica. Want to stay up to date with breaking Geographical stories? Zealandia is thought to have broken apart from a much larger continent called Gondwanaland between 83 and 79 million years ago. In fact, Luyendyk coined the word in 1995. Among the evidence for Zealandia: The crust that makes up Zealandia is much shallower than the surrounding oceanic crust, and its geologic makeup looks more like continental versus oceanic crust.

Zealandia is a lost continent beneath the waves of the South Pacific Ocean. A new report published by the journal of the Geological Society of America recommends recognising the 4,900,000km 2 sunken land mass of Zealandia – of which the islands of New Zealand and New Caledonia are the principle exposed features – as a fully independent continent, separate from Australia, Antarctica or any other neighbours.. Much of Zealandia is thought to contain fossils from times when life thrived on more of the continent. He has also worked for the The figure above shows land masses in green and the entire continent of Zealandia in grey. New Zealand’s flora and fauna differs from every other large land-mass on earth due to its long isolation and uniqueness as a (near) mammal-free environment. NC–New Caledonia; WTP–West Torres Plateau; CT–Cato Trough; Cf, NEVER MISS A STORY - Follow Geographical on Social, Copyright © 2019 Syon Geographical Ltd. All Rights Reserved. But still, some would argue about it and will say that there is still one more continent, the 8th continent, Zealandia. But Luyendyk says it was never intended to describe a new continent. Zeelandië, Zeelandia, Zealandia of Tasmantis is een verzonken stuk continentale korst rondom Nieuw-Zeeland en Nieuw-Caledonië.Tussen 85 tot 130 miljoen jaar geleden scheidde een stuk continentale korst dat Nieuw-Zeeland en Australië omvatte van Antarctica af. A continent is commonly defined as a large piece of landmass separated by natural features like sea, mountain, desert etc. Earlier this year, scientists argued that the known seven continents had a long-lost brother Zealandia, a narrow strip of land that encompasses New Zealand and lies off the east coast of Australia, and whose landmass is mostly 3,280 feet (1,000 meters) below sea level beneath the ocean's surface. When that vast supercontinent of Gondwanaland broke up into five continent-sized pieces, it created South America, Africa, Antarctica, India, Australia – and Zealandia. “Zealandia is the youngest, thinnest, and most submerged” continent and the scientific value of including Zealandia to the list of continents could be huge. The Zealandia continent, also known as Te Riu-a-Māui, is a 5-million-square-kilometer (2-million-square-mile) continent found in the southwest Pacific.

Scientists studying Zealandia say it has several of the key characteristics of a continent, including a distinctive geology, and an elevation above the surrounding sea bed. Roughly 94 per cent underwater, Zealandia has been found to be a piece of continental crust which once formed as much as five per cent of the super-continent of Gondwana, but has failed to gain widespread recognition alongside the larger, more obvious continents of Africa and the Americas. Zealandia is also known as Tasmantis, the New Zealand continent, and the Zealandia continent. It surrounds New Zealand and stretches north to New Caledonia and south beyond subantarctic Campbell Island.

A new continent may be about to join the seven we recognize today. And it’s not uninhabited.That’s because roughly six percent of the landmass’s nearly two million square miles are still above sea level as New Zealand and its outlying islands. Zealandia is the geological continent that encompasses New Zealand and New Caledonia. Scientists studying Zealandia say it has several of the key characteristics of a continent, including a distinctive geology, and an elevation above the surrounding sea bed. So, how do we actually determine what is and isn’t a continent? While the name ‘Zealandia’ wasn’t coined until 1995, the idea of it was first noted by J Graham Cogley in 1984 in a Reviews of Geophysics report, when he calculated the total area of the 14 land masses he deemed as continents to be 210,400,000km² – roughly 41 per cent of the Earth’s surface.

The isolated species living here were affected dramatically around 800 years ago, when humans from Polynesia settled in New Zealand. Nick Mortimer, a geologist with GNS Science in New Zealand, and his fellow authors of the most recent report, have a definitive answer: ‘Following Cogley and the vagaries of general conventional usage, we propose that the name continent be applied to regions of continental crust that are >1 Mkm2 [1,000,000km2] in area and are bounded by well-defined geologic limits. In these terms, Zealandia emerges as nearly five times larger than necessary to constitute a separate geological continent, making it the seventh largest, as well as the ‘youngest, thinnest, and most submerged’. Abut 94% of Zealandia is now submerged underwater -- but some parts of the continent are still above land, making up New Zealand and other small islands.

More areas of Zealandia will be mined in the future. It was discovered using satellite mapping. Informative, authoritative and educational, this site’s content covers a wide range of subject areas, including geography, culture, wildlife and exploration, illustrated with superb photography. However, which terra exactly constitute those ‘major land masses’ is harder to determine than the six/seven we may have learnt about in school, or the five which make up the iconic Olympic rings (Europe and Asia being, clearly, not geologically separate in any way, and therefore defined on a more cultural basis than anything else). These are the highest points of what was once a much larger expanse of land.As a result, Zealandia wasn’t so much discovered as recognized. Zealandia is a submerged continent buried deep beneath the waves of the Pacific. In general it is agreed there are seven continents in the world: Africa, Antarctica, Asia, ...
