摘要

After two decades of hardwork, on 5 February 2012, a team of Russian scientists began drilling at Lake Vostok, the largest of more than 140 sub-glacial lakes and the most deeply buried of the lakes hidden under the Antarctic ice cap. The Russian team plans to send a robot into the lake to collect water samples and sediments from the bottom of the ice well at the end of 2012, when the new Antarctic summer starts. Unusual forms of life could be found in the water layer of the lake as an ecosystem has been sealed off-below the ice for millions of years and atmospheric conditions, which could resemble those of the hypothesized ice-covered ocean of Jupiter抯 moon, Europa. The lake water is supported on a bed of sediments which is 70 m (230 ft) thick, offering the possibility that they contain a unique record of the climate and life in Antarctica before the ice cap formed. Geothermal heat from the earth抯 interior may warm the bottom of the lake and allow the melting of ice, and the ice sheet itself insulates the lake from cold temperatures on the surface.
