Ice caps accumulate snow on their upper surfaces, and ablate snow on their lower surfaces. [6] An ice cap in equilibrium accumulates and ablates snow at the same rate. The AAR is the ratio between the accumulation area and the total area of the ice cap, which is used to indicate the health of the glacier. [6]
Ice caps can be round, circular, or irregular in shape. [5] Ice caps often gradually merge into ice sheets making them difficult to track and document. [5] Examples include: Jostedal Glacier, Norway; Devon Ice Cap, Canada; Barnes Ice Cap, Canada; Vatnajökull, Iceland; Flade Isblink, Greenland

An ice cap is a mass of glacial ice that covers less than 50,000 km 2 (19,000 sq mi) of land area covering a highland area and they feed outlet glaciers. [4]: 52 Many Icelandic ice caps and glaciers lie above volcanoes, such as Grímsvötn and Bárðarbunga, which lie under the largest ice cap, Vatnajökull.
Austfonna is an ice cap located on Nordaustlandet in the Svalbard archipelago in Norway. Covering an area of 7,800 km 2, [1] it is Europe's third-largest glacier by area and volume, after the Severny Island ice cap of Novaya Zemlya, Russia, and Vatnajökull in Iceland. [2] The combined area of Austfonna and the Vegafonna ice cap is 8,492 km 2. [3]
The Ad Astra Ice Cap is an ice cap in Ellesmere Island, Nunavut, Canada. [2] It is located in the Conger Range, north of the head of Tanquary Fiord. The Ad Astra ice cap has a maximum elevation of 1,676 m (5,499 ft). [3] Mummified wood was found in a valley at the base of the ice cap. [1]
