The frozen continent of Antarctica was the last continent humanity set foot on. The first documented landings made below the Antarctic Circle took place in 1820, when Admiral Fabian Gottlieb von Bellingshausen and the crew of the Vostok and Mirny, as part of the Russian Antarctic Expedition, made land at Peter I Island and Alexander Island.
Halley VI was built in Cape Town, South Africa. [24] The first sections were shipped to Antarctica in December 2007. They were assembled next to Halley V, [citation needed] then dragged one-by-one 15 km (9.3 mi) to the intended final location and connected. [25] Halley VI was officially opened in Antarctica on 5 February 2013.
Ice streams are a type of glacier [1] and many of them have "glacier" in their name, e.g. Pine Island Glacier. Ice shelves are listed separately in the List of Antarctic ice shelves. For the purposes of these lists, the Antarctic is defined as any latitude further south than 60° (the continental limit according to the Antarctic Treaty System). [2]
The Patuxent Trough is more than 300 km long and over 15 km wide, while the Offset Rift Basin is 150 km long and 30 km wide. These three troughs all lie under and cross the so-called "ice divide" - the high ice ridge that runs all the way from the South Pole out towards the coast of West Antarctica. [18]
The described detection strategy, along with its South Pole position, could allow the detector to provide the first robust experimental evidence of extra dimensions predicted in string theory. Many extensions of the Standard Model of particle physics, including string theory, propose a sterile neutrino; in string theory this is made from a ...
Antarctic sea ice is the sea ice of the Southern Ocean. It extends from the far north in the winter and retreats to almost the coastline every summer. [1] Sea ice is frozen seawater that is usually less than a few meters thick. This is the opposite of ice shelves, which are formed by glaciers; they float in the sea, and are up to a kilometre thick.

The ice sheet is around 2.2 km (1.4 mi) thick on average and is 4,897 m (16,066 ft) at its thickest point. [2] It is also home to the geographic South Pole, South Magnetic Pole and the Amundsen–Scott South Pole Station. The surface of the EAIS is the driest, windiest, and coldest place on Earth.
