Cold Regions Microbial Ecology and Biomarkers
Water emerging from springs in glaciers in the Canadian Arctic has been identified as containing bacterial cell and biofilms. These deposits of yellow and white minerals are formed on the surface as the water evaporates. These deposits include gypsum and sulfur. The water is no more than 1-2 degrees C and the microbes may be growing in the plumbing system of the glacier interior. Such occurrences in terrestrial glaciers may be mirrored on Mars during periods when the polar ice caps are melting or retreating. We will continue to study the products from spring eruptions in Arctic glaciers, including analysis of bimolecular techniques.
