NASA discovers mysterious ice circles in the Arctic Sea

On April 14, 2018, a NASA scientist photographed images of mysterious ice holes over the eastern Beaufort Sea. A scientist, John Sonntag, said he spotted the circles 50 miles northwest of the Mackenzie River Delta.

The main purpose of the trip was to observe the ice, but somehow the circles caught their eye. A sea scientist, Chris Polashenski, said, "he has seen these features before, but cannot properly explain them." He thought it could be just seals popping out of the water but wasn't 100 percent sure.

According to Walt Meier, a scientist at the National Snow and Ice Data Center, he also believes it could be seals surfacing for air. "Or it could be a sort of drainage feature that results from when the hole is made in the ice,” Meier told NASA.

Another scientist, Chris Shuman, a University of Maryland at Baltimore County glaciologist, believes the circles were formed in shallow waters, and that the circles were formed by warm springs. He also believes it could've formed by "groundwater flowing from the inland mountains or from certain currents making its way to the ocean’s surface," according to Newsweek.
