Our Critical Zone Observatory is a platform for the greater critical zone research community. We encourage critical zone scientists to utilize our well-studied sites and wealth of datasets.


Field Research

To conduct research at our field sites, please contact our Field Manger, Erin Stacy.

Our Field Manager coordinates field campaigns for researchers and assists in permitting processes. Because our sites are located on federal lands, research permits are usually required. Additional support can be provided to obtain road and trail information, lodging and camping options, safety updates, and other resources to help researchers prepare for field campaigns. In-person support on field days may also be available upon request, depending on staff availability.

We maintain records of researchers utilizing our field sites - when they are there and what they are doing - for safety and reporting purposes. Reserachers are required to keep our Field Manager informed on when they will be conducting field campaigns.
