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 sounds like a swarm of bees or an orchestra warming up, the scientists say.
The German Alfred Wegener Institute for Polar and Marine Research publishes the results of its study in the journal Science.
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.
They say the signal was similar to volcanic tremors from Kilauea and Mount St Helens.
Tracking the signal, the scientists found a 50 by 20 kilometre iceberg that had collided with an underwater peninsula and was slowly scraping around it.
"Once the iceberg stuck fast on the seabed it was like a rock in a river," says one of the study authors Dr Vera Schlindwein.
"The water pushes through its crevasses and tunnels at high pressure and the iceberg starts singing.
"The tune even goes up and down, just like a real song."

I saw this on the Yahoo news captions the other day but don't know how to post them. It's really interesting. Thanks for putting it up. th:

There is just something so interesting about icebergs. They are beautiful yet so dangerous. It's funny to find out they can sing! Even if there is Nancy Drew logic behind it!

I think of icebergs as one of Nature's wonders. They really are beautiful.

I love this :) even if it sounds a bit eery are you sure this isn't the soundtrack for a ghostmovie :lol:

It could be used for one, but it's the real thing. :lol:
