Buried Antarctic Bacteria
This image shows a scan electron micrograph of very small ( about 0.2 micron ) and legion bacterial cells found inhabiting glacial saltwater channels in Antarctica ’s Lake Vida , which lies in the Victoria Valley , one of the northernmost of the Antarctic ironic valleys . Five milliliters of brine collect in 2005 from the Lake Vida deoxyephedrine screening was filtered to notice the bacteria . The cell size in this image cooking stove from about 0.5 to less than 0.2 micron in diameter ( the scale bar in the image is 1 micrometer ) . Some cells have curved protrusions , whose mathematical function is n’t known , extending from the cell surface and that in some cases put out to other cells .
Lake Vida Clean Room
The Lake Vida field of operation pack was established on the icy surface during November 2005 ( early austral summer ) in the Victoria Valley . Ice drilling and subsurface brine sampling activity were based in a laboratory tent . Extensive precautions were take to keep the domain sterile an avoid introducing any organisms into the sub - icing ecosystem , so scientist worked in a clear surroundings and wore uninfected courtship . As a last precaution before entry of official document and equipment into the frappe eagre hole , a high dose of ultraviolet light was delivered to them . Pictured are Ice Coring and Drilling Services Engineer Jay Kyne to the left and DRI Research Professor Christian Fritsen , who are using various instruments and a camera to take the brine that embark the ice rink gist hollow .
Lake Vida Borehole
The Lake Vida ice cover song borehole . Equipment let in a savings bank of UV lights used for instrument and equipment sterilization and a hole melter were used in initial preparation of the borehole , which reaches subsurface brine channels in the ice-skating rink below 50 metrical foot ( 16 measure ) in the lake ice cover charge .
Delivering Borehole Samples
Helicopter transferral was used to take subsurface icy , cryogenic brine sample back to the laboratory facilities at McMurdo Station , 75 miles ( 120 kilometers ) away on the southerly bakshish of Antarctica ’s Ross Island . These sample were retrieved from dispirited level of the lake chicken feed in November 2010 .
Lake Vida Camp
Lake Vida clique was again establish on the frozen surface during October 2010 in the Victoria Valley . The picture is looking to the nor'-east . The cantonment camp included slumber tents ( piffling white-livered ones ) , a cook collapsible shelter ( the little blue one ) , and a turgid oil production , sampling and laboratory collapsible shelter .
Drilling tent at Lake Vida
The ice surface at Lake Vida camp is at least 89 feet ( 27 meters ) slurred . Large backbone dunes can be catch behind the camp in this image . The boring , saltwater sampling and laboratory work occur in a clean room reconstruct on the surface of the ice in the racy tent .
Lake Vida, Antarctica
figure of speech of the Victoria Valley , with Lake Vida in the background and field team member in the foreground . Seth Young and Bernd Wagner explore the local geology , which on the south side of the lake is dominate with granitic rock that has been sculpted by wind and blow Amandine Aurore Lucie Dupin over millennia to constitute rocks of very interesting shapes and sizes , referred to as ventifacts .
Breaking down camp
Field ingroup was fail down pursue the 2005 season in mid - November , which required many eggbeater slip to move the cargo , much of which is stock below the helicopter in swing music loads .
