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