Heat-loving bug found deep beneath the ice
provides evidence of underwater volcanic activity
30 Mar 06 – Russian and French researchers have found traces of a heat-loving bacterium that may live beneath Lake Vostok, a frozen lake in Antarctica covered by more than 3km (1.8 miles) of ice.
The bacterium, which usually lives in temperatures of 50-60C, suggests
may have some kind of hydrothermal heating system or vents its base, making it more active than anyone had realized. Lake Vostok
Hundreds of lakes exist beneath the thick Antarctic ice sheet, but with an area of 14,000 sq km (about the extent of
), Vostok is by far the largest. Lake Ontario
We expected to find life adapted to a cold environment but instead we found exactly the opposite," said Jean-Robert Petit of the Laboratory of Glaciology and Geophysics of the Environment in
