DeMMO sampling trip to the Sanford Underground Research Facility in Lead (SD)

My first day of the project “Deep Mine Microbial Observatory”. I visited six underground sites at the Sanford Underground Research Facility (SURF) in Lead, South Dakota. Here, several reactors were installed. The aim is to characterize microbial dark matter in oligotrophic environments that could help us understand life on exoplanets. The project is partially funded by NASA and Packard Fellowship for Science and Engineering.
