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 debouches, debouche into the water here: Scott Glacier (East Antarctica), 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 Doug ...

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 primarily in the Eastern Hemisphere south of the Indian Ocean, and separated from West Antarctica by the Transantarctic Mountains. It is generally greater in elevation 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. Location and description Almost completely covered in thick, permanent ice, East Antarctica comprises Coats Land, Queen Maud Land, Enderby Land, ...

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&nb ...

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 afte ...

Bowman Island
Bowman Island is a high ice-covered island, about long and from wide, shaped like a figure eight. Bowman Island is located at . Bowman Island rises above the northeastern part of Shackleton Ice Shelf, which partially encloses the island, northeast of Cape Elliott. Discovered on January 28, 1931, by British Australian and New Zealand Antarctic Research Expedition (BANZARE) under Sir Douglas Mawson, who named it for Isaiah Bowman, then Director of the American Geographical Society.

International Hydrographic Organization
The International Hydrographic Organization (IHO) (French: ''Organisation Hydrographique Internationale'') is an intergovernmental organization representing hydrography. the IHO comprised 102 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 and through its capacity building programs and offices. The IHO enjoys observer status at the United Nations, where it is the recognized 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 During the 19th century, many maritime nations established hydrographic offices to provide means for improving the navigation of naval and merchant vessels by providing nautical publications, nautical charts, and oth ...

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, 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 are: where a ...

Denman Glacier
Denman Glacier is a glacier that is 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 Thomas Denman, 3rd Baron Denman, Lord Denman, Governor-General of Australia in 1911, a patron of the expedition. The canyon under Denman Glacier has been found by the BedMachine Antarctica project (under the leadership of the University of California, Irvine) to be the Extreme points of Earth#Lowest natural points, 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. ...
