Nearing the Limits of Life on Earth

It took Jackie Goordial over 1000 Petri dishes before she was ready to accept what she was seeing.

At the bottom of a frigid Antarctic lake, a thin layer of green slime is generating a little oasis of oxygen, a team including UC Davis researchers has found.

Many view Antarctica as a frozen wasteland. Turns out there are hidden interconnected lakes underneath its dry valleys that could sustain life and shed light on ancient climate change.

Where Ice sheet, Ocean and Land Converge

Using a specially designed hot-water drill to cleanly bore through a half mile of ice, a National Science Foundation (NSF)-funded team of researchers has become the first ever to reach and sample the "grounding zone," where Antarctic ice, land and sea all converge.

A National Science Foundation (NSF)-funded research team has successfully tested an autonomous underwater vehicle, AUV, that can produce high-resolution, three-dimensional maps of Antarctic sea ice.

On The Road to Lake Untersee: We are completely packed up now, using the Everest tracked vehicle, pulling two sleds behind it.

The team is on the ice, having arrived ok at Novolazarevskaya Station yesterday afternoon.

Researchers this week published a paper confirming that the waters and sediments of a lake that lies 800 meters (2,600 feet) beneath the surface of the West Antarctic ice sheet support "viable microbial ecosystems."

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.
