Mawson Sea
Mawson Sea is a proposed sea name along the Queen Mary Land coast of East Antarctica east of the Shackleton Ice Shelf. West of it, on the western side of Shackleton Ice Shelf, would be the Davis Sea. To the east would be Bowman Island and Vincennes Bay. The name was proposed as part of the 2002 International Hydrographic Organization (IHO) draft. This draft was never approved by the IHO (or any other organization), and the 1953 IHO document (which does not contain the name) remains currently in force. Leading geographic authorities and atlases do not use the name, including the 2014 10th edition World Atlas from the National Geographic Society and the 2014 12th edition of the Times Atlas of the World. Two important glaciers debouche into the water here: Scott Glacier and Denman Glacier. Calving of Denman Glacier gives rise to the periodically appearing Pobeda Ice Island. It would be named in honor of Australian Antarctic explorer Douglas Mawson Sir Douglas Mawson O ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Queen Mary Land
Queen Mary Land or the Queen Mary Coast () is the portion of the coast of Antarctica lying between Cape Filchner, in 91° 54' E, and Cape Hordern, at 100° 30' E. It is claimed by Australia as part of the Australian Antarctic Territory. It was discovered in February 1912 by the Australasian Antarctic Expedition (1911–14) under the leadership of Douglas Mawson, who named it for Mary of Teck, queen consort of George V George V (George Frederick Ernest Albert; 3 June 1865 – 20 January 1936) was King of the United Kingdom and the British Dominions, and Emperor of India, from 6 May 1910 until Death and state funeral of George V, his death in 1936.

East Antarctica
East Antarctica, also called Greater Antarctica, constitutes the majority (two-thirds) of the Antarctic continent, lying on the Indian Ocean side of the continent, separated from West Antarctica by the Transantarctic Mountains. It lies almost entirely within the Eastern Hemisphere and its name has been accepted for more than a century. It is generally higher than West Antarctica and includes the Gamburtsev Mountain Range in the center. The geographic South Pole is located within East Antarctica. Apart from small areas of the coast, East Antarctica is permanently covered by ice and it has relatively low biodiversity, with only a small number of species of terrestrial plants, animals, algae, and lichens. The coasts are the breeding ground for various seabirds and penguins, and the leopard seal, Weddell seal, elephant seal, crabeater seal and Ross seal breed on the surrounding pack ice in summer.

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 ...

Davis Sea
Davis Sea is an area of the sea along the coast of East Antarctica between West Ice Shelf in the west and the Shackleton Ice Shelf in the east, or between 82° and 96°E. The name "Davis Sea" appears in most leading geographically authoritative publications such as the 2014 10th edition World Atlas from the National Geographic Society and the 2014 12th edition of the ''Times Atlas of the World'', unlike neighboring proposed water body names such as the Russian-proposed Cooperation Sea to the west. According to the ''Great Soviet Encyclopedia'', it stretches from 87°E to 98°E, and is up to deep. Its area is given as only . Other authorities such as National Geographic assign it a much smaller extent. The sea borders the Leopold and Astrid Coast portion of Princess Elizabeth Land, then Kaiser Wilhelm II Land, Pravda Coast and Queen Mary Land. The never-approved 2002 draft fourth edition of ''Limits of Oceans and Seas'' identifies that the Tryoshnikova Gulf (named after ...

International Hydrographic Organization
The International Hydrographic Organization (IHO) is an intergovernmental organisation representing hydrography. , the IHO comprised 98 Member States. A principal aim of the IHO is to ensure that the world's seas, oceans and navigable waters are properly surveyed and charted. It does this through the setting of international standards, the co-ordination of the endeavours of the world's national hydrographic offices, and through its capacity building program. The IHO enjoys observer status at the United Nations, where it is the recognised competent authority on hydrographic surveying and nautical charting. When referring to hydrography and nautical charting in Conventions and similar Instruments, it is the IHO standards and specifications that are normally used. History The IHO was established in 1921 as the International Hydrographic Bureau (IHB). The present name was adopted in 1970, as part of a new international Convention on the IHO adopted by the then member nations. T ...

Debouches
In hydrology, a debouch (or debouche) is a place where runoff from a small, confined space discharges into a larger, broader body of water. The word is derived from the French verb ''déboucher'' (), which means "to unblock, to clear". The term also has a military usage. Geology In fluvial geomorphology, a debouch is a place where runoff from a small, confined space emerges into a larger, broader space. Common examples are when a stream runs into a river or when a river runs into an ocean. Debouching can generate massive amounts of sediment transport. When a narrow stream travels down a mountain pass into a basin, an alluvial fan will form from the mass deposit of the sediment. The four largest rivers (the Amazon, the Ganges-Brahmaputra, the Yangtze and the Yellow) are responsible for 20% of the global discharge of sediment in to the oceans by debouches. Geography In fluvial geography, a debouch is a place where a body of water pours forth from a narrow opening. Some examples ar ...

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] |
