Russian Team Prepares To Penetrate Lake Vostok 237
Lanxon writes "Lake Vostok, which has been sealed off from the world for 14 million years, is about to be penetrated by a Russian drill bit. The lake, which lies four kilometers below the icy surface of Antarctica, is unique in that it's been completely isolated from the other 150 subglacial lakes on the continent for such a long time. It's also oligotropic, meaning that it's supersaturated with oxygen — levels of the element are 50 times higher than those found in most typical freshwater lakes."
Why do they need to drill to this lake? (Score:1, Interesting)
I fail to see the need to drill to this lake so far below the surface. For one thing I would be worried about bringing back up who knows what with organisms and bacteria that we have not seen before that could be dangerous, also don't you think they would be contaminating this lake by drilling into it?

...release unknown, ancient pathogens into the atmosphere...
which can't survive in our environment which has 1/50 the oxygen they are used to?
...so they can drill it next year to extract specimens...
like 2012? uh oh, you may be on to something. :-)

No, it means that the lake has very few nutrients and is therefore not terribly productive biologically. see here [wikipedia.org]. Many lakes that fall into the oligotropic chategory are also Oxygenated but it is not why they are oligotropic.
The real question I have is where that Oxygen is coming from. There probably isn't much photosynthesis going on at that depth which means either Oxygen is being imported to the system, it isn't being consumed very rapidly or it's being generated somehow.
