Antarctic ice shelf 'sings' as winds blow across its surface
Winds blowing across Antarctica's Ross Ice Shelf causes its surface to vibrate, producing a near-constant set of seismic "tones", according to a new research. It was also found that the pitch of this seismic hum changed when weather conditions altered the surface. "It's kind of like youâre blowing a flute, constantly, on the ice shelf," one of the researchers said.
