According to China Daily
soon as the end of the Antarctic summer , Russian scientists working day and night had to drill through the last 5 meters of ice . Russian scientists in 1970 in the Antarctic scientific research station Vostok drilling. Even now the Antarctic is now summer, but the temperature outside is still a low of minus 40 degrees Celsius .
According to U.S. media reported on February 4 ,[link widoczny dla zalogowanych], is the Russian Antarctic research scientists announced that they will drill through 3,750 meters of ice , snow cover is a glimpse of 1,500 years old , but not yet frozen ground Lakes, which explore ancient life, and trying to uncover the mystery of the Ice Age species evolution .
scientists believe that there are a large number of Lake Vostok have not yet found in the human species, able to understand the ice age and the situation prior to biological evolution to provide fresh evidence and clues. According to scientists speculate that these 500 million years ago, the lake formed by the sea should be the survival of the current worms,[link widoczny dla zalogowanych], mollusks and algae that the primary biological .
data show that glaciers in the Antarctic under total of 150 underground lakes, the exploration of Lake Vostok is the world's largest subglacial lake ,[link widoczny dla zalogowanych], an area comparable to the world's largest capacity ,[link widoczny dla zalogowanych], most Freshwater Lake Baikal . Lake Vostok in the super- saturated with oxygen, has a unique biological environment.
Although the perennial ice cover by a few kilometers , but scientists said the lake for ice , this thick layer of ice can be like Polar snow and cold . So even after such a long time , most of the lakes under the Antarctic ice is not frozen .
