CZO National Office Coordinator
See our Contact page for current PI Committee Chair, a position that rotates annually.
Critical Zone Observatories (CZOs) are natural watershed laboratories for investigating Earth surface processes mediated by fresh water. Research at the CZO scale seeks to understand these little-known coupled processes through monitoring of streams, climate/weather and groundwater. CZOs are instrumented for hydrogeochemical measurements and are sampled for soil, canopy and bedrock materials. CZOs involve teams of cross-disciplinary scientists whose research is motivated and implemented by both field and theoretical approaches, and include substantial education and outreach.
For more information, see the About page and Research page.
