Ice calving, also known as glacier calving or iceberg calving, is the breaking of ice chunks from the edge of a glacier. [1] It is a form of ice ablation or ice disruption. It is the sudden release and breaking away of a mass of ice from a glacier, iceberg, ice front, ice shelf, or crevasse. The ice that breaks away can be classified as an ...
Second, melting or weakening of ice mélange as a consequence of climate change could trigger a sudden or widespread release of tabular icebergs and lead to rapid ice-shelf disintegration. Ice-shelf rifting, a long-term process that culminates in tabular iceberg release, is strongly influenced by sea ice and other types of ice, which fill the rift.
Some named Antarctic iceshelves. Ice shelf extending approximately 6 miles into the Antarctic Sound from Joinville Island. An ice shelf is "a floating slab of ice originating from land of considerable thickness extending from the coast (usually of great horizontal extent with a very gently sloping surface), resulting from the flow of ice sheets, initially formed by the accumulation of snow ...
The Ross Ice Shelf is the main outlet for several major glaciers draining the West Antarctic Ice Sheet, which contains the equivalent of 5 m of sea level rise in its above-sea-level ice." The report added that observations of "iceberg calving" on the Ross Ice Shelf are, in their opinion, unrelated to its stability. [10]
The calving of A-38 off Ronne ice shelf. The A38-B iceberg splits. Rapid sea ice breakup along the Ronne-Filchner ice shelf, January 2010. The Filchner–Ronne Ice Shelf or Ronne–Filchner Ice Shelf is an Antarctic ice shelf bordering the Weddell Sea.

Calving is when a glacier, ice sheet, or ice shelf loses mass via chunks of ice breaking off into the ocean and forming icebergs. Subglacially-sourced channels form when buoyant meltwater from an ice sheet or glacier reaches the grounding lines and interacts with the surrounding ocean.
At the margin between glacial ice and water, ice calving takes place as glaciers begin to fracture, and icebergs break off from the large masses of ice. [11] [9] Iceberg calving is a major contributor to sea level rise, but the ocean is not the only place that can experience ice calving. [11] Calving can also take place in lakes, fjords, and ...
