Task 7. (10 points)
Read the text below and fill in the spaces provided with one word only. Do not use words
from the text. For each correct answer you will be given 1 point.
It began in 1989 when Russian scientists at a remote Antarctic research field station started
to drill a hole into the ice. The researchers knew exactly what they were looking for: trapped
in the ice would be tiny bubbles of air that carried secrets of the Earth’s past climate.
It worked, and the now famous Vostok (named after the station) ice core was the first to show
a clear link between raised carbon dioxide levels and a warmer atmosphere over the past
400 000 years.
But, as the scientists drilled, it became clear that something else was lurking under the ice.
Seismic surveys and satellite images confirmed the scientists’ suspicions: lying directly
underneath the Russian station, down in the freezing depths, was a lake of fresh, liquid water.
The size of the underground reservoir, now called Lake Vostok, stunned experts. Covering
an area twice the size of Yorkshire, it is up to 1200m deep. More intriguingly, its icy roof has
probably sealed the lake from the rest of the planet for at least 15 million years. With no
sunlight and just traces of nutrients to provide energy, biologists quickly realised that if there
is life in the lonely waters of Lake Vostok - and there is life everywhere else on Earth where
there is fresh water - it might be very different from life on the rest of our planet.
The one thing the scientists could be sure of was that puncturing the lake’s surface
with a dirty Russian drill loaded with 60 tonnes of kerosene to stop it freezing was not a good
idea. With the bottom of the borehole just 120m above the pristine lake’s frozen surface,
drilling operations at Vostok were suspended in 1998.
Vostok is the biggest and most famous lake underneath Antarctica, but not the only one.
Some 145 have been identified so far, and more will follow. Formed by geothermal heat
melting the base of the ice sheet, which then acts as an insulating blanket to stop the water
refreezing, all the lakes are dark, isolated from the outside world and all pose the same
problem to scientists who want to probe them for life: “If we find life we have to be sure
that it was there before and that we didn’t put it there,” says John Priscu, an ecologist
at Montana State University who has studied lakes in Antarctica.
The Russian team insists it will enter Vostok very soon. Other scientists are unhappy
with the plan, but are powerless to act. “I think it’s going to be too risky for the science
involved. It’s going to be a contaminated mess,” says Priscu at Montana. “I don’t like
the idea. It seems we’re going back to the Amundsen-Scott stuff and we don’t need that.
I don’t think a nation has to be first any more.”

However, the Russians, whose 7.9. is situated over the lake,
intend to reach Vostok soon on their own. Experts from other countries express
their 7.10 attitude to the Russian decision.
