The walrus sucks the meat out by sealing its powerful lips to the organism and withdrawing its piston-like tongue rapidly into its mouth, creating a vacuum. The walrus palate is uniquely vaulted, enabling effective suction; researchers measured pressures in the oral cavity as low as -87.9 kPa in air, and -118.8 kPa underwater. [77]
Vostok Research Station is around 1,301 kilometres (808 mi) from the Geographic South Pole, at the middle of the East Antarctic Ice Sheet.. Vostok is located near the southern pole of inaccessibility and the south geomagnetic pole, making it one of the optimal places to observe changes in the Earth's magnetosphere.
The United States maintains the southernmost base, Amundsen–Scott South Pole Station, and the largest base and research station in Antarctica, McMurdo Station. The second-southernmost base is the Chinese Kunlun Station at 80°25′2″S during the summer season, and the Russian Vostok Station at 78°27′50″S during the winter season.
The citizen science scheme by WWF and British Antarctic Survey aims to help conserve walruses in the face of climate change.
Monitoring stations in Antarctica are few and far between; prior to 1995, Vostok was the only research station on the Antarctic Plateau above the elevation of 3,000 m (with the exception of Plateau Station during the brief period that it was active in the 1960s), with no other stations for several hundred kilometers in any direction ...
Antarctica contains research stations and field camps that are staffed seasonally or year-round, and former whaling settlements. [1] Approximately 12 nations, all signatory to the Antarctic Treaty , send personnel to perform seasonal (summer) or year-round research on the continent and in its surrounding oceans.
Lake Vostok (Russian: озеро Восток, romanized: ozero Vostok) is the largest of Antarctica's 675 known [3] subglacial lakes. Lake Vostok is located at the southern Pole of Cold , beneath Russia's Vostok Station under the surface of the central East Antarctic Ice Sheet , which is at 3,488 m (11,444 ft) above mean sea level .
A walrus calf seemingly left behind by her herd near Alaska’s northernmost city is alert and “sassy” as she receives care at a nonprofit wildlife response center hundreds of miles away ...
