Collaborative Research: Evolution of Subsurface Microbe-Rock-Fluid Systems

Our vision is to develop an interdisciplinary framework and the techniques necessary to track the evolution of microbe-rock-fluid systems in the earth’s shallow crust (upper few km) to understand couplings and feedbacks of fluid circulation, fluid-rock reactions and subsurface microbial habitability and make predictions of the lower limits to freshwater and life over geologic time. Our goal is to illuminate key driving factors and permeability dynamics controlling convergence of disparate fluids and rocks which alter subsurface redox dynamics, mineral equilibria, and metabolic potentials for microbial activity in specific locations (‘hot spots’) and geologic time periods (‘hot moments’). Anticipated research outcomes include providing fundamental insights, adaptive modeling platforms, and analytical and theoretical advances cutting across multiple Earth Science disciplines, while generating critical information on the lower boundaries of the active hydrologic cycle and microbial ecosystems required for effective management of subsurface water and energy resources and storage of alternative energy and waste-products. Integrated Education and Public Outreach plans include engagement and training of a diverse cohort of undergraduate students and development of hands-on modules and videos to facilitate Earth Science education programs for under-served school children.
