Critical Zone Science

We examine subsurface processes and ecosystem-climate interactions.

Earth's critical zone is the “heterogeneous, near surface environment in which complex interactions involving rock, soil, water, air, and living organisms regulate the natural habitat and determine the availability of life-sustaining resources”. A healthy critical zone supports productive ecosystems that produce the food we eat, provides natural pollution control, and nourishes natural resources upon which our economy depends.
