Under the Antarctic subglacial lake Hodgson found living organisms
Researchers from the BAS (British Antarctic Survey), and the University of Northumbria (UK) confirmed reports that the Antarctic subglacial lake Hodgson were discovered microbes that founded their colonies are still 100,000 years ago.
Drilling of the Arctic ice, scientists reached the lake, whose depth is 93 meters, and the length and width of 1.5 kilometers, and took samples. The researchers say that since the end of the last ice age on the planet lake was hidden under a massive layer of ice thickness of about 400 meters. Many years later, this thickness is reduced to just 4.3 meters. Scientific journal Diversity writes that the British researchers made their way to the bottom of the lake ice and plunged into it by about 3.2 meters, where he took the necessary samples for analysis.

“This is the first successful case of sampling of sediments subglacial Antarctic lakes, in which micro-organisms are found, showing that life can exist even in those conditions that were previously considered too extreme by us” – says researcher David Pierce of the University of Northumbria.
“The fact that these organisms are able to survive in such incredible conditions, indicating that they have evolved in a different way. And we are, too, can lead to other amazing discoveries, “- he added.
Among the microbes found in this ice lake, 23.8 percent were actinobacterium 21.6 percent – protobacteria, 20.2 percent were identified as planctomycetes and 11.6 – hlorofleksy.
Interestingly, the remaining 23 percent do not fall under any known type or classification of microorganisms. Scientists say it is possible for them a whole new kind of undocumented.
“This is just the beginning of our study, so we still have a lot of work to identify all types of microorganisms found” – says David Pierce.
Scientists hope that understanding how life could survive and grow in these subglacial lakes will help to further open light on the question of whether the existence of life forms in such extreme conditions, but on the other planets .
