In the Arctic Ocean, scientists from the NASA a series of holes in the polar ice discovered, in a random pattern. What those holes are, and how they are caused, however, have no idea of.
Space agency NASA has conducted over the past ten years numerous reconnaissance flights above the north Pole, in an attempt to include the effect of climate change on the coldest places on Earth to better understand. For its research Operation IceBridge baptized – she used the most sophisticated tools, such as laser altimeters and satellites.
Nevertheless, the organization has, to date, no explanation for the random pattern of ijsgaten that on april 14, discovered in the east of the Beaufort sea north of Canada and Alaska. An area that is already five years not more extensively was studied.
“Today we have a couple of minutes long, and these circular holes are seen,” wrote researcher John Sonntag that day in his log book. “I can’t remember that I ever had seen something like this before. Three unexplained, amoebevormige holes in a vast, further continuous piece of ice.’
NASA made the picture of Sonntag public, as possible, with the hope that someone with a plausible explanation for the ijsgaten come would come. They used him even as a submission for the ‘Puzzler from april 2018, ” a monthly contest where the general public is asked a mysterious object to describe.
Participants came with a few possibilities come up. “The holes may be remnants of meteorites, or dried-up salt lakes’, it was under more.
“We know that the ice is quite thin, soft and even flexible,” said geophysicist Don Perovich, meanwhile, to NASA. ‘That ijsgaten would be so in a natural way can arise, for example, by currents of warmer water, think glacioloog Chris Shuman.
Other scientists swear that the holes made by seals, in particular harp seals,which make their way through the ice have been bitten to the vents. ‘Meteoorinslagen seem to me to be already excluded’, according to Walt Meier of the National Snow and Ice Data Center. ‘There are the ijsgaten much to close to each other.’
