An early model to explain the asymmetry between the conjugate eastern Australian and northern Zealandia margins (comprising the Dampier Ridge‐Middleton Basin‐Lord Howe Rise‐New Caledonia Trough‐Norfolk Ridge; Figure 1) invoked crustal‐scale detachments (Lister et al., 1991). The ridges rise above the sea floor to heights of 1,000–1,500 m (3,300–4,900 ft), with infrequent rocky islands rising above sea level. Stuart Rankin/Flickr (CC BY-NC 2.0), NASA.

People who work in this field are known as geologists. In geography, Zealandia refers to a sunken continent. In his work, Mortimer argues that Zealandia has all the necessary characteristics: it rises high above the oceanic crust, has important geological distinctions, the most important of which is that its land crust is significantly thicker than the oceanic, distinctly separated from the environment, and large enough.

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. When will Zealandia rise out of the ocean? There are other geologic features that rise from the seafloor. Scientists dub smaller fragments of continental crust as “microcontinents.” Those that are attached to larger continents are subcontinents. In modern times, there are six geologic continents: North America, South America, Eurasia, Africa, Australia and Antarctica. That means it fits better as a continent than a microcontinent, Mortimer and his colleagues maintain. He proposes that an intermediate term could help bridge the gap between microcontinent and full-blown continent. This area now has several countries with a population of around five million.

The name Zealandia was first proposed by geophysicist Bruce Luyendyk in 1995 as a collective name for New Zealand, the Chatham Rise, Campbell Plateau, and Lord Howe Rise. Some people, however, combine the last two — Europe and Asia — into one huge Eurasia. Only 4 percent of Zealandia rises above sea level (dark gray), including New Zealand. It is very dense and tends to sort of sink down when it meets and collides with continental crust. With a total area of about 4,900,000 km2 (1,900,000 sq mi), Zealandia is substantially bigger than any features termed microcontinents and continental fragments. Zealandia’s official website describes itself as “A portal for geoscience webmaps and information on the Te Riu-a-Māui / Zealandia region.” The name Te Riu-a-Māui is what Zealandia translates to in the Maori language.

But swaths of other continents also are submerged along their margins (light-shaded regions). These islands rise east of Australia in the Southern Hemisphere. Only New Zealand, New Caledonia and a few small islands peek above the waves over it. The EM1/EM2 signature is likely emphasized here because a higher volume of oceanic lithosphere has been recycled in northern Zealandia in the last 100 Ma compared to the south. The narrower eastern ridge forms New Caledonia, Norfolk Ridge, the Northland peninsula of New Zealand and the Chatham Rise. Zealandia is about six times larger. But there is no such group to officially validate new continents.

Because sea levels rise and fall over time, geological definitions of continents consider the continental crust and not just the part above sea level today. Astronomers of the International Astronomical Union (IAU) created this three-part scientific definition of a planet in August 2006 to determine Pluto’s status. The mantle is semi-solid and generally divided into an upper and lower mantle. The figure above shows land masses in green and the entire continent of Zealandia in grey.

Zealandia comprises of two parallel ridges that rise above the seafloor to heights of around 1,000–1,500 m. The ridges are separated by a failed rift that overtime has become filled with a graben (a depressed block of the crust). Scientists will have to judge for themselves if Zealandia should be added to the ranks of continents. La limite du continent est tirée d'informations venant de : « Nick Mortimer; Hamish Campbell (2014) Zealandia - Our Continent Revealed, Londres: Penguin Books, p. 54 ISBN: 978-0-143-57156-8.

Users are able to pan around the maps and switch layers to “rise” above the seafloor. ... Scientists believe that Zealandia split from Gondwana, an ancient super-continent that included the land mass in present-day Southern Hemisphere, some 85 million years ago. But having continental crust isn’t enough to confirm Zealandia is a new continent. Scientists previously assumed that New Zealand and its neighbors were an assortment of islands — fragments of long-gone continents and other geologic odds and ends. He is a geologist at GNS Science in Dunedin, New Zealand. Implicit in Luyendyk’s paper was that this was a large region of continental crust, although this was only mentioned in passing and he did not characterize and define Zealandia as we do here. And unlike the others, around 94 percent of Zealandia hides beneath the ocean. The publication, as well as Science News magazine, are published by the Society for Science, a nonprofit 501(c)(3) membership organization dedicated to public engagement in scientific research and education. Zealandia illustrates that the large and obvious in natural science can be overlooked. Il y a quelques mois, nous vous parlions de Zealandia, ce nouveau continent découvert par des scientifiques dans les eaux autour de la Nouvelle-Zélande et immergé à 1000 mètres de profondeur. Prime examples of these objects: Pluto and Ceres. As it turns out, we might have one more continent to add to Earth’s collection. And many wingless arthropods (ancestors to spiders and insects) colonized the land. (Both submerged and dry areas contribute to a continent’s overall size.) It also could aid in the study of how geologic forces reshape landmasses over time. Over the past twenty years, mounting evidence has pointed to a lost continent straddling the Australian and Pacific plates: Zealandia. If this lower size limit is accepted, Zealandia would become the scrawniest continent by far. Because ocean crust is thinner than continental crust, it doesn’t rise up as far. Ocean crust typically is made of basalt, a type of volcanic rock. This area hosts numerous countries, largely New Zealand but also parts of Australia and others.

Its discovery illustrates that “the large and obvious can be overlooked in science,” he says. He is a geologist at Carleton University in Ottawa, Canada. To accomplish the third feat, the object must be big enough to have pulled neighboring objects into the planet itself or to have slung them around the planet and off into outer space. continent     (in geology) The huge land masses that sit upon tectonic plates.
