Scientists discover 'Singing Iceberg'
Scientists monitoring earth movements in Antarctica believe they have found a singing iceberg .
Sound waves from the iceberg had a frequency of around 0.5 hertz, too low to be heard by humans, but by playing them at higher speed the iceberg sounded like a swarm of bees or an orchestra warming up, the scientists said.
Between July and November 2002 researchers picked up acoustic signals of unprecedented clarity when recording seismic signals to measure earthquakes and tectonic movements on the Ekstroem ice shelf on Antarctica's South Atlantic coast.
"The tune even goes up and down, just like a real song."
