The term iceberg basically refers to a large piece of freshwater ice that has broken off a glacier or an ice shelf and is floating freely in open water. This incredible video that you’re about to see shows the largest iceberg break up ever filmed in known history. Continue reading for more.
If you haven’t experienced a break up live, 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.
