Scientists have captured audio of the Antarctic ice shelf ‘singing’ and it sounds decidedly eerie. The low-frequency sounds, which have to be sped up for humans to hear them, are the vibrations caused by the wind as it blows across the snow dunes.
The sound has actually always been there and occurs constantly – the only difference now is that scientists have found a way to record it and make it audible.
“It’s kind of like you’re blowing a flute, constantly,” said geophysicist Julien Chaput.
The audio was captured using sensitive sensors buried two meters beneath the ice. Scientists are hoping that the sounds could help them to monitor the collapse of the ice shelf.
An example recording of the phenomenon can be heard in the video below.
