Astrobiologists Discover Strange Benthic Microbial Mats in Antarctica
"Photosynthetic microbial mats forming large conical structures up to half a meter tall have been discovered by astrobiologists in Lake Untersee, Antarctica. This research is described in a forthcoming article in the journal Geobiology. During the expedition, three members of the field team, Dale Andersen (SETI Institute), Ian Hawes (University of Canterbury), and Chris McKay (NASA ARC) explored the lake beneath its 3 meter thick ice-cover and discovered the large conical structures that dominate the under-ice landscape."
