Critical Zone Observatories

Critical Zone Observatories (CZO) is an interdisciplinary collaborative research project across nine institutions with the purpose of understanding the chemical, physical, geological, and biological processes that both shape the surface of Earth and support terrestrial life. Active CZO sites include locations in Boulder Creek, Calhoun, Eel River, Intensively Managed Landscapes (IML), Jemez River Basin & Santa Catalina Mountains, Luquillo, Reynolds Creek, Susquehanna Shale Hills, and Southern Sierra.

Funded by the National Science Foundation, CZO has been working since its 2007 inception to critically engage the scientific community and increase understanding of the importance of Critical Zone science.
