- One Scientist on the Flight said he would never see anything like it.
An annual NASA airborne mission over both poles revealed mysterious holes
NASA's Earth Observatory was spotted April 14 north of Canada in the eastern Beaufort Sea during a flight as part of the Arctic Circle's sea ice of the Operation IceBridge mission, which maps changes in sea ice every year at the North and South Poles. Mission scientist John Sunday spotted the ice holes some 50 miles northwest of Canada's Mackenzie River Delta,
"We saw these sorta-circular features only for a few minutes today," Sunday said in his field observations.

Exploring the cause of those ice holes is difficult. It's possible, NASA said, that they've come through the ice and formed the hole so they have a place to pop up and breathe above the surface. Walt Meier told NASA.
One thing is clear: The ice seen in the above picture is fairly new, and it's thin, the theory of the cause of those holes is plausible, the witnesses said.
"It's definitely an area of thin ice, as you can see the rafting near the holes and the color is gray enough to indicate little snow cover," he says. IceBridge project scientist Nathan Kurtz told NASA. "I'm not sure what kind of dynamics could lead to the semicircle-shaped features surrounding the holes.
