The CZO program began in 2007 with 3 CZOs, with the number increased to 6 CZOs in 2008. At that time efforts transformed a program of independent CZO sites into a broader community research network, and the network expanded to 10 CZOs in 2013. Initial efforts focused on: i) developing common measurements and data to facilitate cross-CZO research, ii) forming cross-CZO working groups around various issues, iii) articulating shared conceptual models for the critical zone, iv) promoting cross-CZO dialog and research activities, v) establishing a common data portal for the 10 CZOs, and vi) sharing of ideas and resources to create additional opportunities for community research on the critical zone.
Researchers investigating critical zone properties and processes at the Southern Sierra Critical Zone Observatory conduct research at other Critical Zone Observatories in the United States of America and other countries such as France, Germany, and China. By relaying data and research findings within the network of Observatories and throughout the critical zone research community, we are catalyzing rapid development and refinement of earth systems models.
A key goal of research at our and other Critical Zone Observatories is to construct whole-watershed energy, water, carbon and other mass balances for a variety of environmental settings. Having these data and models available allows critical zone researchers to create and use a uniform research platform.
Several cross-CZO research efforts are ongoing, including studies of organic matter quantity and quality within observatories, hydrologic processes within ecosystems, ecological changes due to climate changes, and regulation of critical zone formation.
The National Science Foundation’s U.S. Critical Zone Observatory Network was designed to create common research methods, allowing for comparable data across CZOs and with other local, regional, and global monitoring efforts.
1. CZ structure and evolution; including 3D spatial distribution and characterization of bedrock, soil, water, vegetation, and topography; regolith and drainage valley evolution; rates of soil production, differentiation, erosion, and deposition.
2. Event-based and continuous fluxes across CZ interfaces; including bedrock-soil; soil-atmosphere; soil- vegetation; vegetation-atmosphere; landscape surface-soil-water.
3. Changes in storage (i.e., budgets) of major CZ reservoirs at the catchment scale;
Science Across Virtual Institutes (SAVI) is a National Science Foundation program with funding opportunities that can be used for national and global cross-CZO research.
SAVI serves as a catalyst to foster many activities efficiently and economically, and seeks to:
