Catalina-Jemez CZO: Is it evolution by jerks down deep too?

JWH 206

Jon Chorover will talk about CZO research.

ABSTRACT: One hypothesis being tested at the Catalina-Jemez CZO is that the critical zone evolves structure that enables energy dissipation during short-term hydrologic episodes, including pulsed throughputs from surface soils to deeper subsurface stores of water and reduced carbon. Several lines of evidence from the Catalina-Jemez CZO indicating the importance of deep subsurface hydrologic flows on (bio)geochemical processes will be discussed. Experimental approaches to quantify subsurface couplings of hydrology, biogeochemistry, and microbial ecology in weathered bedrock will be discussed.
