Greenland 12,000 A few years ago, a huge iron meteorite left behind a large crater over Paris, which was recently discovered under ice by modern radar.
It is the first crater ever found in Greenland and in common with all Earth's land ice caps. According to the size of this crater is 25 of all known on our planet, writes in the journal Science Advances.
The 31-kilometer crater is under the ice of the Hawthorne. The meteorite had to have a significant impact in the region, perhaps even in the world, the scientists said. But his story begins to tell.
"It was necessary to throw the atmosphere out of particles that had to affect the climate." There may have been a lot of ice fragments, and lots of fresh water hit the paper barrier between Canada and Greenland, which affected the ocean currents throughout the region, "said one of the authors. John Padan, a professor of electrical engineering and computer science at the University of Kansas.
"The evidence shows that the collision probably took place after GreenLink's green ice, but the team is still looking at the exact time," he said.
The discovery was made in 2015, but the team has since confirmed the findings.
The initial discovery was made on the basis of the Arctic Arctic Climate Assessment Program (Arctic Regional Climate Assessment Program, PARCA) And the data from Operation IceBridge's Polar Ice Tracking mission.
Later, additional data was collected using more advanced radar technology.
"It is still not possible to give the crater to a direct date, but its condition is very suggestive of the fact that it was created after the ice began to cover Greenland, so it is under $ 3 million a year, and perhaps (created) only 12 thousand.Year, near the end of the last ice age "Said Prof. Kurt Keuer, a professor at the University of Pittsburgh. Kurt Keuer of the Danish Institute of Natural History, Center for Geomatics.
Scientists plan to try to take material from the bottom of the glacier to help them find out more about the collision time and its impact on Earth at the same time.
