Ice bergs sing! I mean they produce sound waves! This is what the scientists claim. But, how is it so that expeditors, who walked on the surfaces at the poles, never talked of it? Scientists have explanations also for it. They say, the icebergs produce sound waves of frequency of around 0.5 hertz, which is too low to be heard by humans. But, they claim that by playing them at higher speed the iceberg sounded like a swarm of bees or an orchestra warming up. Don’t the poles sound interesting and entertaining now? 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. They further say that the tune plays up and down like music.
