|Scientists from the Alfred Wegener's Institute for polar research had captured the sounds made by a colliding iceberg.
" 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.' "
