You can listen to the underwater sound of the Antarctic Ocean via the Perennial Acoustic Observatory in the Antarctic Ocean (PALAOA). Underwater sound is recorded by means of two hydrophones by PALAOA, an autonomous, wind and solar powered observatory located on the Ekström ice shelf (Boebel et al., 2006). The data stream is transmitted via wireless LAN from PALAOA to the German Neumayer Base. From there, a permanent satellite link transmits the data to the AWI in Germany. PALAOA's Livestream page has links to the audio stream in both MP3 and OGG-Vorbis.
