Chugunov Island
Chugunov Island () is a small ice-covered island, lying at the seaward extremity of the Shackleton Ice Shelf, between the projections of Denman Glacier Denman Glacier is a glacier wide, descending north some , which debouches into the Shackleton Ice Shelf east of David Island, Queen Mary Land. It was discovered in November 1912 by the Western Base party of the Australasian Antarctic Expedition ... and Scott Glacier. It was mapped from aerial photos taken by U.S. Navy Operation Highjump, 1946–47. It was rephotographed by the Soviet expedition of 1956 and later named for N.A. Chugunov, an aerologist who lost his life in the Antarctic in 1958. See also * List of antarctic and sub-antarctic islands References * Islands of Queen Mary Land {{QueenMaryLand-geo-stub ...

Shackleton Ice Shelf
Shackleton Ice Shelf is an extensive ice shelf fronting the coast of East Antarctica from 95° E to 105° E. It extends for an along-shore distance of about , projecting seaward about in the western portion and in the east. It occupies an area of . It is part of Mawson Sea and separates the Queen Mary Coast to the west from the Knox Coast of Wilkes Land to the east. Discovery and naming The existence of this ice shelf was first made known by the USEE under Charles Wilkes who mapped a portion of it from the ''Vincennes'' in February 1840. It was explored by the Australian Antarctic Expedition under Douglas Mawson (1911–14) who named it for Sir Ernest Shackleton. The extent of the ice shelf was mapped in greater detail in 1955, using aerial photography obtained by US Navy Operation Highjump, 1946–47. Further mapping by the Soviet Expedition of 1956 showed the portion eastward of Scott Glacier to be a part of this ice shelf. Important Bird Area A 500 ha ...

Denman Glacier
Denman Glacier is a glacier wide, descending north some , which debouches into the Shackleton Ice Shelf east of David Island, Queen Mary Land. It was discovered in November 1912 by the Western Base party of the Australasian Antarctic Expedition under Sir Douglas Mawson. Mawson named the glacier for Lord Denman, Governor-General of Australia in 1911, a patron of the expedition. The canyon under Denman Glacier has been found by ''BedMachine Antarctica'' project (under the leadership of the University of California, Irvine) to be the deepest natural location on land (or at least not under liquid water) worldwide, with the bedrock being below sea level. Calving of Denman Glacier into the Mawson Sea gives rise to the periodically appearing Pobeda Ice Island. Instability and retreat A 2020 study reported Denman Glacier has retreated 5.4±0.3 km over a 20-year-period from 1996 to 2017–2018. The study projects that the glacier has the potential to undergo a rapid, irreversibl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scott Glacier (East Antarctica)
Scott Glacier () is a glacier, wide and over long, flowing north-northwest to the Antarctic coast between Denman Glacier and Mill Island. It was discovered by the Western Base Party of the Australasian Antarctic Expedition (1911-1914) under Mawson and named for Capt. Robert F. Scott.
