Antarctic tunnels: 820-foot-high channels have been discovered under Antarctic ice
So. And these amazing structures are nearly as tall as the Eiffel Tower. Can you imagine?
From there, you can’t see anything! But it is beneath this deep ice shelf in Antarctica that scientists have discovered 820-foot-high channels. The mysterious tunnels are nearly as high as the Eiffel tower.
This project led by the British Antarctic Survey flew a plane over the Flichner-Ronne Ice Shelf. And there, at the bottom of the ice, they spotted (radars and satellite images) under-ice tunnels. They suggest these long cavities were formed by meltwater flowing underneath the ice, over land, and into the ocean.
This would signify that water underneath ice sheets pours out into the ocean in focused channels and not in thin, continuous layers, as previously thought.
Now, it would be so great to know if these Antarctica underground channels are only present under the Flichner-Ronne Ice Shelf or homogeneously distributed under Antarctica’s ice cap!
