An enlargement of a paper published in vol. CLI and CLII of the Journal of the Franklin institute The legendary "Terra Australis incognita" and voyages leading from a belief to a disbelief in it.--Voyages up to and including the discovery of the continent of Antarctica.--Voyages subsequent to the discovery of the continent of Antarctica
A speculative representation of Antarctica labelled as ' Terra Australis Incognita ' on Jan Janssonius's Zeekaart van het Zuidpoolgebied (1657), Het Scheepvaartmuseum The name given to the continent originates from the word antarctic, which comes from Middle French antartique or antarctique ('opposite to the Arctic') and, in turn, the Latin antarcticus ('opposite to the north').
Antarctica also has some relatively small regions that are clear of ice and snow, and there are some surface lakes in these regions. They called for on the ground seismic studies, or drilling, to determine a more reliable number. These lakes are buried beneath deep layers of glacial ice.

[74] [75] [76] According to one study, if the Paris Agreement is followed and global warming is limited to 2 °C (3.6 °F), the loss of ice in Antarctica will continue at the 2020 rate for the rest of the 21st century, but if a trajectory leading to 3 °C (5.4 °F) is followed, Antarctica ice loss will accelerate after 2060 and start adding 0.5 ...
The Antarctic plate is a tectonic plate containing the continent of Antarctica, the Kerguelen Plateau, and some remote islands in the Southern Ocean and other surrounding oceans. After breakup from Gondwana (the southern part of the supercontinent Pangea ), the Antarctic plate began moving the continent of Antarctica south to its present ...
Antarctica is the largest ice desert in the world. Some 98% of Antarctica is covered by the Antarctic ice sheet , the world's largest ice sheet and also its largest reservoir of fresh water . Averaging at least 1.6 km thick, the ice is so massive that it has depressed the continental bedrock in some areas more than 2.5 km below sea level ...
Lambert Glacier is a major glacier in East Antarctica. At about 80 km (50 mi) wide, over 400 km (250 mi) long, and about 2,500 m (8,200 ft) deep, it is the world's largest glacier.
