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.
The Ross Ice Shelf is one of many such shelves. It reaches into Antarctica from the north, and covers an area of about 520,000 km 2 (200,000 sq mi), nearly the size of France. [2] [3] The ice mass is about 800 km (500 mi) wide and 970 km (600 mi) long. In some places, namely its southern areas, the ice shelf can be almost 750 m (2,450 ft) thick ...
