A dome-shaped mass of glacier ice, usually situated in a highland area, and generally defined as covering up to 50,000 square kilometres (cf. ice sheet).
A dome-shaped perennial cover of ice and snow over an extensive portion of the earth's surface. Ice caps are considerably smaller than ice sheets, and it is felt improper to refer to the Greenland and
Antarctic Ice Sheets as ice caps. Most ice caps are most probably remnants of the Quaternary Ice Age. The term was first used for the supposedly perennial ice cover at both poles of the earth. However, since it has been found that the ice of arctic waters is largely seasonal, the use of this term to denote arctic polar ice is now considered improper.
A dome-shaped mass of glacier ice that spreads out in all directions; an ice cap is usually larger than an icefield but less than 50,000 square-kilometers (12 million acres).
A dome-shaped ice body with radial flow, largely obscuring the subsurface topography and generally defined as covering less than 50 000 km2 (see ice sheet). The flow pattern is less influenced by the
subsurface topography than is true of icefields and valley glaciers. The definition embraces small as well as large ice bodies. The usage '(polar) ice cap' for the sea ice cover of the Arctic Ocean or Southern Ocean is confusing and best avoided.
Dome shaped ice mass; Approximately radial ice flow; Upstanding ice mass over bedrock; Not to be interpreted as_ mountain ice cap; Dome shaped ice mass with radial flow; May incorporate Ice domes; Lon
gitudinal profile is in almost all cases even/regular
A dome-shaped accumulation of glacier ice and perennial snow that completely covers a mountainous area or island, so that no peaks or Nunataks poke through.
A cave of ice, usually underneath a glacier and formed by meltwater; cave entrances are often enlarged near a glacier terminus by warm winds; most common on stagnant portions of glaciers.
A vertical face of ice, normally formed where a glacier terminates in the sea, or is undercut by streams. These terms are also used more specifically for the face that forms at the seaward margin of a
n ice sheet or ice cap, and that rests on bedrock at or below sea level.
