Identify large craters with meteor impact below 1 km glaciers in Greenland



It was the first time a collision zone was found where a large meteorite fell from Greenland's snow and ice layer.

The collision zone, about 1 km below the ice, is about 1 km from the glacier of Hiawata Gulf, Greenland, northwest, 31 km across and is located within the 25th largest meteorite collision zone on Earth.

Dr. Kjarr initially analyzed the ground map of the Greenland Glacier created by the US NASA in July 2015 and was the first sign of a round recess in the Hiawatta region.

The team of Dr. Kjarr did not initially believe it was a meteor conflict, but after three years of control, he concluded that the collapse was caused by a meteor conflict of about 1 km. In diameter and the results reported in the Science Journal & Sys last issue.

Researchers placed a next-generation radar on the Alfred Wegener Research Center aircraft and flew over the Hiawatta Glacier to accurately measure the ground under the ice layer. Hence, they observed a typical rim, mean altitude and basic rock remains.
