What does the Antarctic glacier really sound like?
Antarctica's largest ice shelf, the Ross Glacier, is about the size of France, and 90% of its volume is under water.
Scientists plunged 34 highly sensitive seismic sensors into the ice. By analyzing the data coming from them, scientists discovered what they did not expect: constant vibration. The wind passing through the huge snow dunes emitted its own sound. It is interesting that when gusts of wind displaced snow masses on the surface of the glacier, or when the temperature on the surface changed, the sound also changed.
This noise is too low for people to hear without special equipment. But scientists believe that they can follow it, and these sounds can even warn about the state of the Ross Glacier in the face of climate change.Do you like the article?
