Scientists Retrieve Sample From Freshwater Lake Buried Under Ice For 20 Million Years
Scientists have done something they have been working on for over two decades: successfully drilled more than three kilometres through sheer Antarctic ice into a freshwater lake to take a sample. All they really know now is that Lake Vostok has had no contact with atmospheric pollutants for millions of years.
Lake Vostok measures 260 kilometres in length, and 48 kilometres at its widest point, and it lies just over three kilometres beneath the ice in Antarctica. It is known as a subglacial lake.

There are some 400 known subglacial lakes in Antarctica and a process called geothermal energy warms them, which is essentially built up heat rising from the Earth’s core to the surface.
Yesterday, Russian scientists confirmed they’d reached the surface of the lake for the first time, and had accrued 40 litres of water that had been brought to the surface for testing.
Lev Savatyugin a researcher with Russia’s Arctic and Antarctic Research Institute:
There is no other place on Earth that has been in isolation for more than 20 million years. It’s a meeting with the unknown.
His boss, and the head of Russia’s Arctic and Antarctic Research Institute, Valery Lukin, has previously likened the accomplishment to that of the race to the moon.
Many of the scientists believe they are going to find unique organisms and bacteria previously unknown to us.

20 000 000 year old mineral water, it’s the next big thing!

this is why scientist’s are poor.. digging for 20 years in the hopes of finding bacteria?! imagine how much a bottle of this would sell for in camps bay!

“We can confirm, after 20 years of drilling, that this water, tastes like water. That will be all.”
