Here's what it sounds like under Antarctic Ice

ALAOA, the Perennial Acoustic Observatory in the Antarctic Ocean, listens to the waters below Antarctica for the sounds of whales and other marine mammals amidst a soundscape of constantly shifting ice. Here's what they're hearing right now.

PALAOA's Livestream page has links to the audio stream in both MP3 and OGG-Vorbis.

If you're expecting to tune in and instantly hear glorious, crystal-clear whale song, you might be disappointed.
