Microbiologist Jill Mikucki first saw a photo of Blood Falls during a class for her master's degree at Portland State University. It immediately captivated her.

The Tawani Antarctic Expedition group photo, taken just before we started taking down the tents at Lake Obersee. Tomorrow and Monday we say goodbye to Cape Town and start our journeys back to USA, Austria and Russia.

The Everest tracked vehicle is here with a nice large sled in the back and a cabin attached.

We have completed our work here at Lake Obersee, accomplishing most all of our objectives despite a late start due to stormy weather.

I just got off the phone with Dale Andersen who is at Lake Obersee, Antarctica.

We made the first dives beneath the thick, perennial ice (3.6 m) of Lake Obersee yesterday.  

We have had pretty nice weather the last two days so we have taken advantage of it with a fair amount of work. Today we put up the tripod that will support the new met station I am deploying here at Lake Obersee.

The weather today was quite nice. While a bit windy, it was sunny all day which was a nice change of pace.

Today's weather is a major improvement over what we have seen the last two weeks while in Antarctica.

My research team and I are now camped on the shores of Lake Obersee, a few km NE of Lake Untersee in the mountains of Queen Maud Land.

Evidence of diverse life forms dating back nearly a hundred thousand years has been found in subglacial lake sediments by a group of British scientists.

Lake Vostok, the 7th largest (by volume) and 4th deepest lake on Earth, is covered by more than 3,700 m of ice, making it the largest subglacial lake known. The combination of cold, heat (from possible hydrothermal activity), pressure (from the overriding glacier), limited nutrients and complete darkness presents extreme challenges to life.

The Antarctic continental ice cap came into existence during the Oligocene epoch, some 33.6 million years ago, according to data from an international expedition led by the Andalusian Institute of Earth Sciences (IACT)--a Spanish National Research Council-University of Granada joint centre. These findings, based on information contained in ice sediments from different depths, have recently been published in the journal Science.
