Lake Vostok, Please Come In!

The article said the scientists were concerned about possible explosive releases of oxygen and nitrogen. But what about immense hydraulic pressure from the water itself? Maybe the camp has given way to a huge fountain, gradually freezing into some kind of monstrous ice sculpture.

No pressure. When you drill a hole in the ice on a lake for fishing or whatever, you don't get a fountain.
Viruses or Bacteria shouldn't be able to infect us or other wildlife, they must evolve alongside their hosts to be able to make a living.

Do these guys have a fishing license? Perhaps they will catch a trilobite or a sturgeon.

It always worked for Comrade (fill in any Russian name), so why not the Antarctic ice shell. S5

Q, the pressure is about 600x that on the surface due to the massive amount of ice resting on the lake.
Because water will cross ice at very low temperatures and because the water is already under zero degree celcius but still liquid because of pressure, it froze up quickely in the pipe.

Absent of freezing condition, you would have a fontain as high as the one in front of the town of Geneva.

Not enough to rise it out of the drill hole, unless the ice trapped gases under yet higher pressure. Ice floats on water, no matter how thick it is.

I never thought of that Fred. I always presumed there was geothermal heat down there, causing things to melt. Was that in the article?

I was reading an off-line article explaining that at high pressure water remains liquid even under zero degree celcius.
The pressure there is huge.

The said article also stated that there were geothermel source downthere which could help maintain a certain form of life. But these source were very deep and local. Not enough to heat the whole lake.

Maybe if they ever get to sending a submersible down into the lake somehow, they'll find volcanic vents and life found around them like they do often in the Atlantic and Pacific Oceans.
