Antarctica: Earth's southernmost, coldest, driest, and windiest continent, 13,661,000 km², ice sheet holding ~90% of Earth's fresh water, governed by the 1959 Antarctic Treaty, with record sea-ice lows and accelerating ice loss since 2015.

Antarctic and subantarctic gastropod fauna

The Antarctic and subantarctic gastropod fauna comprises several hundred shelled marine snails on the Antarctic shelf and 51 non-marine species on subantarctic islands, with about 75% endemism.

Antarctic Bottom Water

Antarctic Bottom Water (AABW) is the coldest, densest water mass in the ocean, forming around Antarctica's margins and spreading north to fill much of the deep ocean.

Antarctic Circle

The Antarctic Circle is the parallel at about 66°34′S (66.5637°S), where the sun does not set at the summer solstice; first crossed by James Cook in 1773, distinct from the 60°S Antarctic Treaty boundary.

Antarctic continental shelf

The Antarctic continental shelf is the deep (average 450 m, over 1,000 m in places), wide (~125 km) seabed around Antarctica, shaped by glacial overdeepening, source of Antarctic Bottom Water, and conduit for warm Circumpolar Deep Water toward ice shelves.

Antarctic land bridge

The Antarctic land bridge, formalized as the Weddellian Isthmus, was a land connection between southern South America and the Antarctic Peninsula until roughly 55 million years ago.
