What does melting ice sound like? It鈥檚 usually too quiet to hear. But as icebergs crack and crumble they also vibrate. Douglas MacAyeal, a glaciologist at the University of Chicago, discovered that he could use a seismometer to record iceberg vibrations, speed them up and make them audible to the human ear. Listen to those recordings here, along with music that MacAyeal created with the art collective Luftwerk.
