During a routine flyover in the Arctic Ocean earlier this month, a NASA scientist photographed images of mysterious ice holes over the eastern Beaufort Sea. The holes seem to be the first of their kind ever recorded on film, and the researchers struggle to understand what they are and how they got there.
NASA mission researcher John Sonntag has taken the pictures on April 14 and tagged Field Record, "I can not remember seeing this kind of thing anywhere else," NASA reported. The holes were found about 50 miles northwest of the Canadian Mackenzie River Delta, and although the main purpose of the voyage was to make observations of sea ice, the mysterious holes somehow became the highlight of the voyage.

Fellow IceBridge project scientist Nathan Kurtz stated that although he can see from the image that he has holes in thin ice are not yet sure what created them. I am not sure what kind of dynamics could lead to the semicircular features surrounding the holes. I've never seen anything like it, "said Kurtz, NASA reported. 
Walt Meier, scientist.
At the moment, with just one photo, what has caused the holes will remain a mystery. At least until more information about the holes can be gathered.
