kakvih tam ribica ima... to bi bilo zanimljivo kad bi našli žive organizme.... 15 milijuna godina netaknuto... stvarno fascinantno

Baš me zanimaju biolški rezultati, nadam se da ga nisu kontaminirali...
Ponekad se pitam jer itko od njih tamo dolje gledao film ''Stvor'' od Carpentera.. -?

Nesto malo rezultata i ima

“At first there was a lot of hope that we would at least find some signs of life in the ice we’re studying. So far, only thermophilic bacteria that survive at high temperatures have been found. Our biologists engaged in the research say that the water is very clean. In other words, there is not much hope of finding life in the lake’s water,” Vasiliev said.

I sto se tice kontaminacije

“The main thing is the difference in pressure,” said Nikolai Vasiliev of St. Petersburg State Mining University, who supervises the drilling process. “That is, what we have in the borehole is a little less than the pressure in the lake. Then there’s our mixture of kerosene and Freon––it’s lighter than water. That is to say, its density is lower than the density of water. And when the opening is made, the water goes into the hole. But not vice versa.”
