This photograph is of two scientists in the Office of Biological and Environmental Research's Subsurface Science Program processing a core for studying microbial ecology in the deep subsurface. The core was collected and is being processed in a manner designed to minimize alteration of the sediment geochemistry through invasion by oxygen.
