Name Type Definition Description
Crevasse_C Feature Type A deep crack or fissure in a glacier that results from differential movement of ice. -
Crevasse_S Feature Type A deep crack or fissure in a glacier that results from differential movement of ice. -
Esker_C Feature Type A long, narrow ridge of sand and gravel deposited by a glacial stream. -
Esker_S Feature Type A long, narrow ridge of sand and gravel deposited by a glacial stream. -
Glacier_S Feature Type A large mass or river of ice formed by accumulation and compaction of snow on higher ground that is moving slowly down a slope or valley from above the snowline. -
IceCap_S Feature Type A permanent layer of ice covering a tract of land (especially a polar region) or the top of a mountain. Usually includes a surface layer of snow.
IceCliff_C Feature Type The vertical face of a glacier or ice shelf. -
IceCliff_S Feature Type The vertical face of a glacier or ice shelf. -
IcePeak_P Feature Type A rocky peak projecting above a surrounding ice field that may be perpetually covered with ice. -
IcePeak_S Feature Type A rocky peak projecting above a surrounding ice field that may be perpetually covered with ice. -
IceShelf_S Feature Type A floating ice sheet of considerable thickness that is normally attached to the land along its landward edge. Ice shelves are the seaward extension of land glaciers. Limited areas of the ice shelf may be aground where the glacier first enters the water and possibly in other places offshore. Ice shelves are usually of great horizontal extent and have a level or gently undulating surface. The seaward edge of an ice shelf is termed an 'ice cliff'.
PackIce_S Feature Type Term used in a wide sense to include any area of sea ice other than fast ice. Pack ice commonly consists of connected floating plates of ice and has a mosaic look. Fast Ice is defined as sea ice which remains fast, generally in the position where originally formed, and which may attain a considerable thickness. Fast ice is found along coasts, where it is attached to the shore, or over shoals, where it may be held in position by islands, grounded icebergs, or grounded polar ice.
Pingo_P Feature Type A cone or dome shaped mound or hill of peat or soil, usually with a core of ice. It is found in tundra regions and is produced by the pressure of water or ice accumulating underground and pushing upward.
Pingo_S Feature Type A cone or dome shaped mound or hill of peat or soil, usually with a core of ice. It is found in tundra regions and is produced by the pressure of water or ice accumulating underground and pushing upward.
PolarIce_S Feature Type Sea ice that is more than one year old and more than 3 metres thick. Sea ice is any form of ice which has originated from sea water.
SnowIceField_S Feature Type A large area permanently covered by snow and/or ice. May cover land and/or water.
