Do icebergs sing?
Do electric sheep dream of rechargeable batteries?
Between July and November 2002 researchers picked up incredily clear acoustic signals when recording seismic signals to measure earthquakes and tectonic movements on the Ekstroem ice shelf on Antarctica’s South Atlantic coast. The sound waves from the iceberg had a frequency of around 0.5 hertz, but if you’d like to listen to the sounds pitched up into human hearing levels, have a listen to this recording as a .WAV file. Tracking the signal, the scientists found a 50 by 20 kilometre iceberg that had collided with an underwater peninsula which it was slowly scraping against it. Check the bit three minutes into the file – that iceberg was angry! Read more here
