Based on the Köppen climate classification, Icecap Peak is located in the marine west coast climate zone of western North America. [5] Most weather fronts originate in the Pacific Ocean, and travel east toward the Coast Mountains where they are forced upward by the range (orographic lift), causing them to drop their moisture in the form of rain or snowfall.
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]
However, in ice caps, the thickness of the dome is much smaller, measuring roughly up to several hundred metres in comparison. [5] In glaciated islands, ice domes are usually the highest point of the ice cap. [5] An example of an ice dome is Kupol Vostok Pervyy in Alger Island, Franz Josef Land, 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 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]
Iceland as seen from space, with Vatnajökull appearing as the largest white area to the lower right. Vatnajökull (Icelandic pronunciation: [ˈvahtnaˌjœːkʏtl̥] ⓘ, literally "Glacier of Lakes"; sometimes translated as Vatna Glacier in English) is the largest and most voluminous ice cap in Iceland, and the second largest in area in Europe after the Severny Island ice cap of Novaya Zemlya ...
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.
The Flade Isblink has two ice domes, the North Dome and the larger South Dome. [3] Kilen is a roughly triangular stretch of unglaciated flat land in the eastern shore with its apex in the ice cap between the two domes. [4] [5] The northern section of the ice cap is drained by two outlet glaciers flowing in a
