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

The Academy of Sciences Glacier (Russian: ледник Академии наук; Lednik Akademii Nauk) is a large ice cap on Komsomolets Island, Severnaya Zemlya, Russian Federation. It is the largest in Severnaya Zemlya and is also the largest single glacier formation of Russia.
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.
An ice cap climate is a polar climate where no mean monthly temperature exceeds 0 °C (32 °F). The climate generally covers areas at high altitudes and polar regions (60–90° north and south latitude), such as Antarctica and some of the northernmost islands of Canada and Russia .
The ice cap is located south of Amundsen Land and the Nordpasset, at the western end of the De Long Fjord area, east of Freuchen Land across the inner J.P. Koch Fjord, west of Odin Fjord and south of the O.B. Bøggild Fjord. [9]
