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. To use its institutions together to create a unique network that fosters scientific inquiry and discovery with regards to Earth's Critical Zone. Much like the interconnectedness of Earth's critical zone systems, CZO relies upon a range of disciplines, including geosciences, hydrology, microbiology, ecology, soil science, and engineering, to develop a theoretical spatial-temporal framework for critical zone evolution for both quantifiable and conceptualized data analyses.
