Scientists discover singing iceberg in Antarctica
BERLIN (Reuters) - 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.
The German Alfred Wegener institute for polar and marine research publish the results of its study, done in 2002, in Science magazine on Friday.
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.
Tracking the signal, the scientists found a 50 by 20 kilometer 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," said scientist 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."
Somehow, this article makes me smile.
In the midst of all that is doom and gloom about the environment, it's nice to know that icebergs sing...

You always find something really good. 
) the poping and whining was very eerie sounding.
