A large iceberg breaks off the shores of the Antarctic Ice Sheet in Queen Maud Land, or Dronning Maud Land, and floats away in the Southern Ocean. Other smaller icebergs can also be seen floating between the main one and the edge of the ice sheet. Many cracks and rifts are visible in the ice sheet itself.
When a mass of ice suddenly splits off and moves away from its parent glacier, iceberg, or ice shelf in such a way, the event is called calving. Calving of ice shelves is usually preceded by a rift. This ice calving or iceberg calving is a form of ice ablation or ice disruption.
