It accelerates the slow discovery of the Antarctic discovery

A radioactive source of heat that helps to get the ice dissolution from the heart of the Earth Antarctica. It is close to the magnetic South Pole and, in the future, it can cool the mass of the water that accumulates in the base of the glaciers. According to surveys conducted by the British Antarctic Survey (UK), British public researcher in Antarctica published and published its findings in the Journal of Scientific Records.

"The discovery reaffirms that the decommissioning of Antarctic ice also suffers from local effects, such as radioactive sources or volcanoes, as it is an ice-covered continent, that is, unlike the ocean covered in ice on the continent, climate warmth," said Antonio Meloni, the Italian of Antarctica President of the National Scientific Committee, with ANSA.

On the ground too

Under the Antarctic ice, the remains of ancient lost continents are hidden, according to Goce European satellites, and a review of the Earth's gravity was conducted from 2009 to 2013. There are at least three parts, one that was earlier in Africa, Australia, and India, the oldest is the age of 1,000 million and 550 million years.

Published in the Scientific Records Magazine, due to the discovery by the German University of Kiel and the British Antarctic Survey (Bas). The researchers analyzed the data of the European Space Agency (ESA), and the subtle variants of severity evaluated an 80 kilometer resolution and compared the seismic wave trajectory. which allows the internal scan of the planet. Thus, in the depths of the Earth and, in particular, a 3D map of continental plates that opened a window of Antarctica were obtained.

These images of gravity "are revolutionizing the ability to investigate Antarctica in less known continents," said Fausto Ferraccioli, head of research and geology and geophysics. Under the eastern part of Antarctica, we will see an exciting mosaic called "parts of the lost continents". The Antarctic and the rest of the continents reveal the similarities and differences between the crust, "which lasted 160 million years." years ".

In the west of Antarctica was also found a thinner crust with an area of ​​20 to 35 km thick in the eastern part of Antarctica, the relics of the ancient continents were formed by a thickness of 40 to 60 km. youth The remains are at least three and the oldest are part of the Crater Mawson, traces hidden behind the southern parts of Australia and Queen Maud. Both parts are separated by the foot of Mount Gamburtsev, buried under ice.

The third part reflects what Weddell is in the sea and South Pole. Three outsourced from Goce data and, according to researchers, "represent an important Antarctic research element".
