The goal of the CROMO project is to establish a long-term microbial "observatory" into the serpentinite subsurface. The CROMO team has been monitoring several drill wells at the site equipped with fluid and gas sampling lines for high-resolution analyses of the serpentinization-associated microorganisms.
