Under 900 meters thick ice: life under extreme conditions tracked down

        Under hundreds of meters of ice in Antarctica, researchers accidentally discovered life forms adapted to extreme conditions.        </p><div>
        <p>260 kilometers from the open sea, complete darkness and temperatures of minus 2.2 degrees - so far only a few animals have been found under comparable conditions, the scientists report in the specialist journal "Frontiers in Marine Science".  How and when the creatures got to the remote place and what they feed on, according to researchers led by Huw Griffiths from the polar research program British Antarctic Survey, is still unclear.  <a href="https://www.de24.news/"><img class="alignnone size-medium" src="https://www.de24.news/a1/de24.png" alt="© www.de24.news" width="400" height="20" /></a><p>&nbsp;The&nbsp; scientists had actually wanted to take sediment samples and to do this, they drilled through 900-meter-thick ice in the Filchner-Ronne ice shelf of the southeastern Weddell Sea.  Instead of mud, however, they suddenly encountered rock.  Video footage shows rocks covered with life forms.  <a href="https://www.de24.news/"><img class="alignnone size-medium" src="https://www.de24.news/a1/de24.png" alt="© www.de24.news" width="400" height="20" /></a><p>&nbsp;The&nbsp; find shows that the marine life in Antarctica is incredibly special and amazingly adapted to a frozen world, according to Griffiths.</p>            

It is still unclear to which species the animals found sedentary on the rock belong. According to the researchers, it is also unclear what it would mean for the beings if the ice shelf breaks. In view of climate change, time is short to study the animals and protect the ecosystem.
