Earth’s Icy Biosphere
John Priscu (Montana State University) demonstrates that the Earth’s icy systems, particularly the Antarctic ice sheet and related subglacial environments, hold a large and potentially active carbon pool, comprised of phylogenetically and metabolically diverse prokaryotic organisms. He then relates these results to our search for life on other icy bodies in our solar system.
