Curious Circles in Arctic Sea Ice

April 14, 2018, IceBridge mission scientist John Sonntag spotted something he had never seen before.

Sonntag snapped this photograph from the window of the P-3 research plane while flying over the eastern Beaufort Sea. At the time, the aircraft’s location was 69.71° North and 138.22° West, about 50 miles northwest of Canada’s Mackenzie River Delta. “We saw these sorta-circular features only for a few minutes today,” Sonntag wrote from the field. “I don’t recall seeing this sort of thing elsewhere.”

The features are more of a curiosity than anything else. The main purpose of the flight that day was to make observations of sea ice in an area that lacked coverage by the mission prior to 2013. Still, the image sparked a fair amount of intrigue, so we set out to see what we could learn. That’s not always easy based on a photograph or satellite image alone, so the following ideas are speculation.

Some aspects of the image are easy to explain. The sea ice here is clearly young ice growing within what was once a long, linear area of open water, or lead. “The ice is likely thin, soft, and mushy and somewhat pliable,” said Don Perovich, a sea ice geophysicist at Dartmouth College. “This can be seen in the wave-like features in front of the middle ‘amoeba.’”

You would think those Sub Conning Towers would be vulnerable popping through that ice.

Concentrated Salt water. Salt is first pushed out over the initial freeze and take much longer to freeze, it forms pools.

I'm thinking methane from natural gas seeps.

Arctic Ice is melting, sea levels rising hundreds of feet, we are all going to die, women and children first. Al Gore drowns.

(Seal breathing holes probably)

Underwater volcano activity is the probable reason for Arctic ice thinning. Can’t be explained by the atmospheric temperature.

The article states that sea ice was not there until 2013 . So much for “global warming” B.S.
