East Antarctica is significantly larger than West Antarctica, and similarly remains widely unexplored in terms of its volcanic potential. While there are some indications that there is volcanic activity under the East Antarctic Ice Sheet , there is not a significant amount of present information on the subject.
Sledging biscuits are popular on expeditions in Antarctica because they are high in energy. [4] [5] [6] Plasmon biscuits were taken in large quantities by Ernest Shackleton in his Antarctic Expedition of 1902, and were also favored by Douglas Mawson. Plasmon itself was a powdered milk extract used as a fortifying agent that was utilized in ...
Most of Antarctica is covered by the Antarctic ice sheet, with an average thickness of 1.9 km (1.2 mi). Antarctica is, on average, the coldest, driest, and windiest of the continents, and it has the highest average elevation. It is mainly a polar desert, with annual precipitation of over 200 mm (8 in) along the coast and far less inland.

Matthiessen discusses a wide range of topics relating to Antarctica, including the geological and hydrographic forces that historically led to the formation of the continent in the first place, the history (and environmental politics) of southern whaling, the details of many of its native species, and the vexed question of global warming and ...
