Antarctic subglacial lakes: Lake Vostok was reached earlier this month, Lake Ellsworth is planned next. |
--------- Now these are the main subglacial lakes:
Lake Whillans: under 800 meters of ice it is the first subglacial lake discovered to have life! Big finding! It was reached January 28 2013.
Lake Ellsworth: subglacial (~3,400 meters of ice on top!);they started drilling this winter but had to call it off Dec 27th due to technical problems...the equipment needs to be reserviced and who knows how long that will take. Drilling this deep has never been done before and the procedure/technology completely new. What's crazy is that if things had gone according to plan, they would have just about 60 hours to collect all the water/sediment/ice they wanted! After that the hole they made would've frozen completely over...
Lake Vostok: the largest subglacial lake known in Antarctica it sits under a staggering 4,000 meters of ice; in Feb 2012 researchers reached the surface of the lake, no life has been found as of yet but it is still early in the hunt*...

I had this entry as a draft for quite some time but this came across my radar today:
Antarctic Lake Vostok yields 'new bacterial life'
http://www.bbc.co.uk/news/science-environment-21709225Well, they have found bacterial (what looks to be bacterial at least) life! Lots of press about it, now we wait to see what more the scientific team offers...Where does it fall on the tree of life? What might it be living on? Articles say it has 86% similarity with its closest sequenced relative...is this enough to make a new branch on the bacterial tree? What is it eating down there?
