Allison Glacier, Ice stream at Big Ben massif, Heard Island and McDonald Islands, Australia.
Allison Glacier extends from the Big Ben massif down to the sea south of Cape Gazert, with an approximate thickness of 55 meters.
The glacier received its name in recognition of Ian Allison, an Australian glaciologist who conducted research during the French-Australian Antarctic Expedition of 1971.
Scientific research at Allison Glacier contributes to understanding climate patterns and environmental changes in the subantarctic region of the Southern Indian Ocean.
The glacier's location at coordinates 53°04′S 73°24′E makes it accessible for research vessels conducting studies in the Southern Ocean region.
The total glacial area on Heard Island decreased from 288 square kilometers in 1947 to 257 square kilometers by 1988, indicating substantial ice mass reduction.
