Antarctic Analogs For Extraterrestrial Environments

Diving Through A Microbial Landscape in Lake Untersee, Antarctica

"There's not much in the ice-covered lakes in the McMurdo Dry Valleys to interest anglers looking to land the big one. But for scientists who want to know more about some of Earth's earliest organisms -- and, by extension, to recognize what life may look like on other planets -- those unique ecosystems represent a useful portal to the past. Dale Andersen, Dawn Sumner and the rest of their team will spend nearly two months camped out at Lake Joyce in the Pearse Valley to understand more about those behaviors. Several team members, including Andersen, will actually scuba dive in the lake, using fluormeters and microelectrodes while underwater to detect, measure and quantify photosynthetic activity of the benthic mats and obtain samples for lab work on the surface."
