Ice caves on the Mt. Erebus Volcano, frozen lakes in the Dry Valleys and the ice covered McMurdo Sound offer diverse and extremely cold environments in which highly adapted microbial communities use chemical energy from rocks and volcanic gases to build new organic compounds. Join Hubert Staudigel as he presents initial laboratory results and stunning images from the 2012/13 field expedition, including SCUBA diving under the ice and alpine exploration of ice caves.
