Finding paralysis that accelerates resolution under Antarctica


It was discovered under a radioactive heat source, which contributed to the dissolution of ice from the heart of the world. Antarctica. The magnetic is close to the South Pole and can accelerate the melting of frozen mass in this area with the water accumulated in the base of the glacier in the future. It was determined by surveys conducted with the British Antarctic Survey (Bas) radars, which were examined in Antarctica and published by the Scientific Reports magazine.

, The discovery confirms that the dissolution of the ice in Antarctica has been subjected to local influences such as radioactive sources or volcanoes ark unlike the Ice Sea, a glacier-covered continent. "Antonio Meloni, president of the Italian National Science Commission for Antarctica, told ANSA."

Under the ice of Antarctica, according to the European satellite Goce, who studied gravity of the Earth from 2009 to 2013, the remains of the ancient lost continents were hidden. Previously, there were at least three parts in Africa, Australia and India, with the oldest estimated from 1,000 million to 550 million years.

Published in the Journal of Scientific Reports, the discovery is due to the German Kiel University and the British Antarctic Survey (Bas). The researchers analyzed data from the mission of the European Space Agency (ESA), which measures fierce differences from one point to the other in the world with a resolution of 80 kilometers and compares it to seismic waves. This allows you to scan the inside of the planet. In this way, they obtained a 3-dimensional map of the terra- tal plates that opened a window in the depths of the world and especially in Antarctica.

K This is revolutionizing our ability to study the lesser known continent of Antarctica, # says Fausto Ferraccioli, who is responsible for the bass's geological and geophysical research. Under Eastern Antarctica, he added, "we see an exciting mosaic of parts of the continental parts where continents" united until 160 million years ago ", revealing the similarities and differences under the Antarctic and other continents. "

At the same time, it was discovered that West Antarctica had a thinner crust of 20 to 35 kilometers thick than Eastern Antarctica, leaving more of the remains of old continents of 40 to 60 kilometers. youth. The remains are at least three, while the oldest are parts of southern Australia and parts of the so-called Crater Mawson, which includes a vest hidden under the territory of Queen Maud. The mountain range buried under two parts of ice is separated by Gamburtsev.

The origin of the third part between the Weddell Sea and the South Pole is unclear. Three pieces of Goce data appeared and, according to researchers, "represents an important element for the work of Antarctica".
