Russian Scientists May Have Drilled into Previously Untouched Subglacial Lake
International scientists teeter between excitement and concern after
reports from Russian news agency RIA Novosti that Russian scientists
have drilled into the untouched Lake Vostok, 2.2 miles below the surface
of Antarctica.
The lake, discovered in the mid-1990s, is the world’s third largest
and could hold a vast amount of scientific data, both about how lakes
function below the surface of the ice in Antarctica and about the
possibility of discovering previously unknown life forms. That is, if
the kerosene, Freon and other chemicals used in the 20-year drilling
process didn’t leak into the water and ice and contaminate the area.
Crews have tried to reach the lake for over two decades, but the
going is slow, with the limited mobility of transportation in and out of
the area and machinery unable to work most of the year due to the
astonishingly cold temperatures.
While no formal announcement has yet been made about the
breakthrough, scientists around the world say that if the Russians have
indeed tapped into the lake, the body of water could completely change
the way research gets conducted in Antarctica. Learning about conditions
in lakes glossed over with ice could also help inform scientists about
conditions on other planets.
The U.S. and Britain will join the ice drilling in search of
subglacial lakes this year, as the search for information continues on
how our planet’s largest reservoir of fresh water (as ice and subglacial
lakes) changes and reacts to climate conditions. With more than 200
lakes beneath the ice, there’s plenty of drilling left to be done.
Russians drill into Lake Vostok, begin search for life under Antartica’s surface

Thursday, February 9, 1:45 PM
Scientists are taking the search for life in extreme environments to the ends of Earth and beyond. On Wednesday Russian scientists announced they had reached Lake Vostok, a subglacial lake under Antarctica. As AP reported:
Russian researchers reported Wednesday that they had reached Lake Vostok, a pristine body of water untouched by light or wind for about 20 million years. They want to know what type of microbial life — bacteria too small to see — might exist there.
