A common misconception would be that icebergs are silent, white giants, moving noiselessly through the freezing waters of the polar seas. In fact, this couldn’t be further from the truth. Though at the opposite end of the world, crew members of Sir Ernest Shackleton’s Imperial Trans-Antarctic Expedition (1914-1917) commented on the sheer variety of sounds heard in the presence of the Rampart Berg:
“Close to the berg the pressure makes all sorts of quaint noises. We heard tapping as from a hammer, grunts, groans and squeaks, electric trams running, birds singing, kettles boiling noisily, and an occasional swish as a large piece of ice, released from pressure, suddenly jumped or turned over.”
