Scientists researching the Ross Ice Shelf in Antarctica were able to capture an eerie cicada-like hum coming from the depths of the frozen wonder via monitors buried in 2014.
“If this vibration were audible, it would be analogous to the buzz produced by thousands of cicada bugs when they overrun the tree canopy and grasses in late summer,” glaciologist Douglas MacAyeal from the University of Chicago — who was not involved in the study — commented on the report published in the journal Geographical Research Letters.
The Texas-sized slab in the Southern Ocean wasn’t originally sought out for its typically inaudible noises. The expedition’s purpose was to monitor changes in the ice shelf brought on by climate change.
