Antarctica is the coldest, driest continent on Earth, and has the highest average elevation. [19] Antarctica's dryness means the air contains little water vapor and conducts heat poorly. [18] The Southern Ocean surrounding the continent is far more effective at absorbing heat than any other ocean. [20]
The Antarctic sea ice cover is highly seasonal, with very little ice in the austral summer, expanding to an area roughly equal to that of Antarctica in winter.It peaks (~18 × 10^6 km 2) during September (comparable to the surface area of Pluto), which marks the end of austral winter, and retreats to a minimum (~3 × 10^6 km 2) in February.

The Antarctic continental shelf is a submerged piece of the Antarctic continent that underlies a portion of the Southern Ocean — the ocean which surrounds Antarctica. The shelf is generally narrow and unusually deep, its edge lying at depths averaging 500 meters (the global mean is around 100 meters), with troughs extending as far as 2000 ...
