Ice calving. Ice calving, also known as glacier calving or iceberg calving, is the breaking of ice chunks from the edge of a glacier. It is a form of ice ablation or ice disruption and is normally caused by the glacier expanding. It is the sudden release and breaking away of a mass of ice from a glacier, iceberg, ice front, ice shelf, or crevasse.
Glacial Mass Reduction: A Recipe. Drifting snowfall and avalanches cause accumulation, while sublimation, melting and calving cause ablation not just in the zone of ablation but anywhere on a glacier where mass loss occurs. Calving occurs when ice breaks off from part of a glacier.ccumulation happens on a glacier's upper regions in the accumulation zone. Composed mainly of ice with very little new snow, the ablation zone lies at lower altitudes where the glacier is melting, sublimating, or calving, resulting in mass loss.
