What sound can be heard when approaching an iceberg?

a cracking noise
a fizz
a roar
a whisper
When a piece of iceberg ice melts, it makes a fizzing sound called "Bergie Seltzer". This sound is made when the wa­ter-ice in­ter­face reaches com­pressed air bubbles trapped in the ice. As this happens, each bubble bursts, making a 'pop­ping' sound. The bubbles contain air trapped in snow layers very early in the history of the ice, that even­tu­al­ly got buried to a given depth (up to several kilo­me­ter­s) and pres­sur­ized as it trans­formed into firn then to glacial ice.
