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. Zealandia is thought to have broken apart from a much larger continent called Gondwanaland between 83 and 79 million years ago. It would be the smallest continent, by far. Researchers from GNS Science in New Zealand have announced that they mapped the shape and size of the Zealandia continent in unprecedented detail. You can see that it … In fact, Luyendyk coined the word in 1995. Aside … Scientists have just returned from a major expedition to Zealandia, a "hidden" Earth continent, likely submerged beneath the sea surface more than 80 million years ago. Massive?

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. Milford Sound in Fiordland National Park on New Zealand's South Island is actually a tiny tip of the lost continent of Zealandia peeking up from the ocean © kris1138 via Getty Images Much of Zealandia is thought to contain fossils from times when life thrived on more of the continent. WHY SHOULD ZEALANDIA BE CONSIDERED AS A CONTINENT? To know this let’s first understand what is a continent? Zealandia (/ z iː ˈ l æ n d i ə /), also known as Te Riu-a-Māui or Tasmantis, is an almost entirely submerged mass of continental crust that subsided after breaking away from Gondwanaland 83–79 million years ago. It surrounds New Zealand and stretches north to New Caledonia and south beyond subantarctic Campbell Island. Published in the UK since 1935, Geographical is the official magazine of the Royal Geographical Society (with IBG). Zealandia continent lost underwater Zealandia's total area has been mapped to be nearly 2 million square miles (5 million square kilometers). 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 at one time, it was above water. 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. By this definition India, prior to its collision with Eurasia, would be termed a continent.’. (CNN) Under New Zealand, there lies a vast continent on the sea floor.

The isolated species living here were affected dramatically around 800 years ago, when humans from Polynesia settled in New Zealand. A microcontinent is a landmass that has broken off from a main continent. It meets all the criteria for being a continent, and it's not like it's all underwater either. Scientists are making a renewed claim for Zealandia—a land mass that is 94 percent submerged under water and includes New Zealand—to be recognized as a new continent. In addition to being an avid blogger, Michael is particularly The figure above shows land masses in green and the entire continent of Zealandia in grey. 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. 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. New Zealand is a top of a much larger, yet, wholly underwater continent. As the report notes, the Glossary of Geology describes a continent as being: ‘one of the Earth’s major land masses, including both dry land and continental shelves.’. In broad terms, the Australian plate is moving north while the Pacific plate is moving west. The 7% of the continent that is above water makes up the two islands of New Zealand.

The new eighth continent – Zealandia, fulfills the definition of a continent. The Continent of Zealandia The Continent of ZEALANDIA 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. Therefore, how do we define a separate continent, as opposed to being part of a larger neighbour, or merely a microcontinent? He has also worked for the NZ is the last remaining non-submerged part of a land mass called Zealandia, which is considered a current or former continent by some. La Zealandia è una massa quasi interamente sommersa della crosta continentale.

The continent of Zealandia is primarily composed of two parallel mountain ranges, mostly underwater. Zealandia’s landmass was probably completely submerged by about 23 million years ago, and most of it (93%) remains submerged beneath the Pacific Ocean. When that vast supercontinent of Gondwanaland broke up into five continent-sized pieces, it created South America, Africa, Antarctica, India, Australia – and Zealandia. "The scientific value of classifying Zealandia as a continent is much more than just an extra name on a list," the researchers explained. And that is even with counting the underwater area of Zealandia. Zealandia is a submerged continent buried deep beneath the waves of the Pacific. “Zealandia is the youngest, thinnest, and most submerged” continent and the scientific value of including Zealandia to the list of continents could be huge.

It covers some 4.9 million square kilometers (1.9 million square miles). 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. Zealandia, a huge mass of land, is a lost continent that has now sunk to the ocean bed below New Zealand. So, how do we actually determine what is and isn’t a continent?

That’s about the size of the Indian subcontinent. 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). Thankfully for Zealandia, the other three criteria – a significantly high elevation relative to the surrounding oceanic crust, a range of igneous, metamorphic, and sedimentary rocks, and a satisfactorily thick underlying continental crust – also produce results which the authors believe pass the necessary tests: ‘We argue that Zealandia is not a collection of partly submerged continental fragments but is a coherent 4.9Mkm2 continent. Explaining the larger-than-expected number of continents, he wrote: ‘Although Eurasia is still the largest continent, it does not include the separate continents India and Arabia and surrenders northeastern Siberia to North America.
