Listen: Scientists Record Spooky Ice Shelf 'Hum'

Researchers studying a massive ice shelf in Antarctica have discovered  that snow sitting atop the site emits a near-constant humming sound due  to vibrations from the wind. The intriguing observation reportedly came by way of a project which saw nearly three dozen seismic sensors  buried in the Ross Ice Shelf, which is the frosty continent's largest  such mass of frozen material. An examination of the data yielded the  previously-unknown revelation that the ice shelf produces a proverbial  'song' which 'played' continuous over the course of the two years that  the sensors were in place.

It was eventually determined that this humming sound was being created  when the wind swept over the thick layer of snow sitting on the surface  of the ice shelf. Remarkably, researchers also realized that the 'song'  would change depending on different environmental conditions, such as  storms or air temperature changes. The discovery of the sounds is being  heralded as a possible breakthrough when it comes to monitoring the  condition of ice shelves which can often collapse with little to no  observable signs ahead of time.
