  2. Iceberg - Wikipedia

    en.wikipedia.org/wiki/Iceberg

    An iceberg in the Arctic Ocean. An iceberg is a piece of fresh water ice more than 15 meters (16 yards) long [1] that has broken off a glacier or an ice shelf and is floating freely in open water. [2] [3] Smaller chunks of floating glacially derived ice are called "growlers" or "bergy bits".

  3. Ice calving - Wikipedia

    en.wikipedia.org/wiki/Ice_calving

    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 ...

  4. Ice - Wikipedia

    en.wikipedia.org/wiki/Ice

    Ice which calves (breaks off) from an ice shelf or a coastal glacier may become an iceberg. [46] The aftermath of calving events produces a loose mixture of snow and ice known as Ice mélange. [47] Sea ice forms in several stages. At first, small, millimeter-scale crystals accumulate on the water surface in what is known as frazil ice.

  5. Ice rafting - Wikipedia

    en.wikipedia.org/wiki/Ice_rafting

    This debris-covered iceberg was calved from the terminus of Alaska's Sheridan Glacier.. Ice rafting is the transport of various materials by ice.Various objects deposited on ice may eventually become embedded in the ice.

  6. Glacier morphology - Wikipedia

    en.wikipedia.org/wiki/Glacier_morphology

    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]

  7. Ice shelf - Wikipedia

    en.wikipedia.org/wiki/Ice_shelf

    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 ...

  9. Seabed gouging by ice - Wikipedia

    en.wikipedia.org/wiki/Seabed_gouging_by_ice

    Iceberg drifting into shallower waters and gouging the seabed as it comes into contact with it. Drifting sea ice pressure ridges can also gouge the seabed. Seabed gouging by ice is a process that occurs when floating ice features (typically icebergs and sea ice ridges) drift into shallower areas and their keel comes into contact with the seabed.
