DCO ID 11121/8770-8663-8437-4546-CC


  • The Coast Range Ophiolite Microbial Observatory (CROMO) sub-project of the RHC grant sought to document and track microbial populations in a series of groundwater wells in actively serpentinizing terrane in northern California. The work capitalizes upon the recovery of microbiologically validated drill cores in 2011 from the site, and from quarterly records of microbial diversity, abundance, and associated geochemistry. The substantial sampling suite and convenient laboratory facilities and infrastructure at CROMO also allows more complicated efforts to be undertaken, including transcriptomics studies, tracer studies, hydrogeological tests, etc.  The work seeks to link the occurrence, function, and consequences of microbial communities in serpentinizing environments and their linkages to both the subsurface and the surface carbon cycle.
