The first person to report a fossil in the Antarctic was American naturalist James Eights in 1829, who landed probably on King George Island and found a fossilized log measuring 2.5 ft (0.76 m) in length and 4 in (100 mm) in diameter. Eights left the fossil where he found it, rather than collecting and formally describing it. [5]
The flightless midge Belgica antarctica, the largest purely terrestrial animal in Antarctica, reaches 6 mm (1 ⁄ 4 in) in size. [ 114 ] Antarctic krill , which congregates in large schools , is the keystone species of the ecosystem of the Southern Ocean, being an important food organism for whales, seals, leopard seals , fur seals, squid ...
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 ...
The Antarctic Peninsula, roughly 1,000 kilometres (650 mi) south of South America, is the northernmost portion of the continent of Antarctica. Like the associated Andes, the Antarctic Peninsula is an excellent example of ocean-continent collision resulting in subduction. [1]

Scientists from the British Antarctic Survey found that warm ocean water is seeping beneath the ice sheet at its “grounding line” — the point at which the ice rises from the seabed and ...
We used 11 different satellite missions to track Antarctica’s contribution to rising sea levels. Antarctica has lost nearly 3 trillion tonnes of ice since 1992 Skip to main content
As of today, there have been 138 possible volcanoes identified in West Antarctica. [3] There is limited knowledge about West Antarctic Volcanoes due to the presence of the West Antarctic Ice Sheet, which heavily covers the West Antarctic Rift System —a likely hub for volcanic activity. [ 4 ]
