East Antarctica in the context of "Riiser-Larsen Sea"

Queen Maud Land (Norwegian: Dronning Maud Land) is a roughly 2.7-million-square-kilometre (1.0-million-square-mile) region of Antarctica claimed by Norway as a dependent territory. It borders the claimed British Antarctic Territory 20° west, specifically the Caird Coast, Coats Land on the West, and the Australian Antarctic Territory 45° east, specifically Enderby Land on the East. In addition, a small unclaimed area from 1939 was annexed in June 2015. Positioned in East Antarctica, it makes out about one-fifth of the continent, and is named after the Norwegian Queen Maud (1869–1938).

In 1930, the Norwegian Hjalmar Riiser-Larsen was the first person known to have set foot in the territory. On 14 January 1939, the territory was claimed by Norway. On 23 June 1961, Queen Maud Land became part of the Antarctic Treaty System, making it a demilitarised zone. It is one of two Antarctic claims made by Norway, the other being Peter I Island. They are administered by the Polar Affairs Department of the Norwegian Ministry of Justice and Public Security in Oslo.

The Antarctic Plateau, Polar Plateau or King Haakon VII Plateau is a large area of East Antarctica that extends over a diameter of about 1,000 kilometres (620 mi), and includes the region of the geographic South Pole and the Amundsen–Scott South Pole Station. This huge continental plateau is at an average elevation of about 3,000 metres (9,800 ft).

West Antarctica, or Lesser Antarctica, one of the two major regions of Antarctica, is the part of that continent that lies within the Western Hemisphere, and includes the Antarctic Peninsula. It is separated from East Antarctica by the Transantarctic Mountains and is covered by the West Antarctic Ice Sheet. It lies between the Ross Sea (partly covered by the Ross Ice Shelf), and the Weddell Sea (largely covered by the Filchner-Ronne Ice Shelf). It may be considered a giant peninsula, stretching from the South Pole towards the tip of South America.

Dome A or Dome Argus is the highest ice dome on the Antarctic Plateau, located 1,200 km (750 mi) inland. It is thought to be the coldest naturally occurring place on Earth, with temperatures believed to reach −90 to −98 °C (−130 to −144 °F). It is the highest ice feature in Antarctica, consisting of an ice dome or eminence 4,087 m (13,409 ft) above sea level. It is located near the center of East Antarctica, approximately midway between the enormous head of Lambert Glacier and the geographic South Pole, within the Australian claim.

The Australian Antarctic Territory (AAT) is a part of East Antarctica claimed by Australia as an external territory. It is administered by the Australian Antarctic Division, an agency of the federal Department of Climate Change, Energy, the Environment and Water. It is the largest sector of Antarctica by area claimed by any country. Australia is an original signatory to the Antarctic Treaty of 1959, under which all territorial claims are held in abeyance. Only four other countries accept Australia's claim to sovereignty, being New Zealand, the United Kingdom, France, and Norway, all of which have territorial claims in Antarctica and mutually accept one another's claims.

Lake Vostok (Russian: озеро Восток, romanized: ozero Vostok) is the largest of Antarctica's 675 known subglacial lakes and the 16th largest lake in the world by area. Lake Vostok is located at the southern Pole of Cold, beneath Russia's Vostok Station, under the surface of the central East Antarctic Ice Sheet, which is at 3,488 m (11,444 ft) above mean sea level. The surface of this fresh water lake is approximately 4,000 m (13,100 ft) under the surface of the ice, which places it at approximately 500 m (1,600 ft) below sea level.

The lake is named after the Vostok Station, which derives its name from Vostok (Восток), the name of a sloop-of-war, which means "East" in Russian (the lake is also located in East Antarctica). The existence of a subglacial lake was first suggested by Russian geographer Andrey Kapitsa based on seismic soundings made during the Soviet Antarctic Expeditions in 1959 and 1964 to measure the thickness of the ice sheet. Continued research by Russian and British scientists led to the final confirmation of the existence of the lake in 1993 by J. P. Ridley using ERS-1 laser altimetry.

The Transantarctic Mountains (abbreviated TAM) comprise a mountain range of uplifted rock (primarily sedimentary) in Antarctica which extends, with some interruptions, across the continent from Cape Adare in northern Victoria Land to Coats Land. These mountains divide East Antarctica and West Antarctica. They include a number of separately named mountain groups, which are often again subdivided into smaller ranges.

The range was first sighted by James Clark Ross in 1841 at what was later named the Ross Ice Shelf in his honour. It was first crossed during the British National Antarctic Expedition of 1901-1904.

71°20′S 12°18′W / 71.333°S 12.300°W / -71.333; -12.300 Cape Norvegia is a prominent cape on Princess Martha Coast of Queen Maud Land. It marks the northeast extremity of Riiser-Larsen Ice Shelf in East Antarctica, and the border point of Weddell Sea and King Haakon VII Sea. It was discovered by Commander Hjalmar Riiser-Larsen in February 1930 while on an airplane flight from the Norvegia, the ship in which the expedition was made. The cape was named by Riiser-Larsen for the ship.
