Singing Iceberg

Last month it was mice singing love-songs — now we have singing icebergs…

Iceberg

A 50 by 20 kilometre Antarctic iceberg, that had collided with an underwater peninsula and stuck fast on the sea bed, has been found to sing.

    “The water pushes through its crevasses and tunnels at high pressure and the iceberg starts singing.”

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 sounds like a swarm of bees or an orchestra warming up, the scientists say.
