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 .
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]
The ice cap was mapped during the 1952–54 British North Greenland expedition led by Commander James Simpson. It was named in honor of the Royal Air Force in order to commemorate the air transport supplied to the expedition. The name "Adastra Ice Cap" had been suggested by Brian Roberts, but finally "Ad Astra Ice Cap" became the approved name. [2]
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 Agassiz Ice Cap formerly Agassiz Glacier [1] is an ice cap on the central eastern side of Ellesmere Island, Nunavut, Canada. [2] The Agassiz ice cap is about 21,000 km 2 (8,100 sq mi) in area. [2] It is located between the North Ellesmere ice field to the north and the Prince of Wales Icefield to the south.
The Stikine Icecap (sometimes referred to as the Stikine Icefield) is a large icefield straddled on the Alaska–British Columbia boundary in the Alaska Panhandle region. [1] ...
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]
Langjökull (Icelandic pronunciation: [ˈlauŋkˌjœːkʏtl̥] ⓘ, Icelandic for "long glacier") is the second largest ice cap in Iceland (870 km 2 (340 sq mi)), [1] after Vatnajökull. It is situated in the west of the Icelandic interior or Highlands of Iceland and can be seen clearly from Haukadalur .
