The remarkable findings made by the German Alfred Wegener Institute for polar and marine research in 2002 have only now been published in Science magazine.
The institute’s research team had been tracking earth movements and recording seismic signals in Antarctica when they detected some unusual noises.
The source was found to be a 50 by 20 kilometre chunk of ice which had collided with an underwater peninsula.
“Once the iceberg stuck fast on the seabed it was like a rock in a river,” scientist Vera Schlindwein said.
“The water pushes through its crevasses and tunnels at high pressure and the iceberg starts singing.”
At a frequency of around 0.5 hertz, the sounds waves are too low for the human ear.
But sped up, the iceberg sounded like a swarm of bees or an orchestra warming up, the scientists said.
“The tune even goes up and down, just like a real song,” Ms Shlindwein added.
