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 Mesozoic clastic sequence (Number 2-Figure 2) consists of the Mount Flora Formation (MFF), [4] which is a 270 m thick package of plant-bearing coarse sedimentary breccias and conglomerates, with a limited amount of interbedded sandstones and shales. [4] The clastic beds overlay the TPG sediments, and are separated by angular unconformities.
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 ...

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
The striking images, made from sonar readings, can help boats avoid dangerous obstacles in the poorly understood Southern Ocean.
