Austfonna is an ice cap located on Nordaustlandet in the Svalbard archipelago in Norway. Covering an area of 7,800 km2,[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 km2.[3]
Austfonna has a thickness of up to 560 metres (235 meters average thickness), and is 200 km in circumference. The ice dome reaches an elevation of 783 meters above sea level.Script error: No such module "Unsubst".
The southern third of Austfonna is sometimes called Sørfonna, which is a separate ice cap, separated from the main part of Austfonna by a long, ice-filled depression, and forming a separate crestal dome.[4]
Vegafonna ice cap in the southwest is also connected to Austfonna proper, specifically to Sørfonna, and is separated from it by Erica Valley.[4] Vegafonna also forms a separate dome. Immediately west of Vegafonna is Glittne ice cap,[4] which is considered part of the former.Script error: No such module "Unsubst".
Vestfonna in the northwest of the island is a totally separate ice cap (the third largest of Svalbard and Norway).Script error: No such module "Unsubst".
