The Critical Zone Tree: the most instrumented tree in the Sierra Nevada.

In order to increase knowledge about Earth's critical zone and advance Earth systems models, we encourage field site and data use among the critical zone research community. Southern Sierra researchers also strive to rapidly communicate current research activities and findings through frequent presentations and publications.



Field Site and Data Access for Researchers

Interested in conducting research at our site or collaborating with our principal researchers? Our intensively studied field areas are resources for the critical zone research community. We welcome all projects using our sites and data, short-term or long-term, single-discipline or interdisciplinary. Common measurements are collected at Critical Zone Observatories across the U.S. to promote cross-CZO projects. Our core datasets are publicly available here. Background information on our field areas can be found in the Infrastructure section of our website. For more information about utilizing our field sites or collaborating with our team, please contact Field Manager Erin Stacy, PI Roger Bales, or one of our Co-Principal Investigators.


Publications

We have a growing collection of over 75 peer-reviewed articles and books detailing and synthesizing research from the Southern Sierra Critical Zone Observatory. These publications also include cross-CZO studies utilizing multiple Critical Zone Observatories to compare critical zone properties and processes across regions with varying climates, geologic settings, ecosystems, or anthropogenic impacts.


Scientific Conferences

Southern Sierra researchers have presented over 100 scientific conference posters and talks since 2007. Find us at national and regional meetings hosted by the American Geophysical Union, Ecological Society of America, Soil Science Society of America, European Geophysical Union, and International Society for Optics and Photonics. We also present at conferences focused on Sierra Nevada research, including the Yosemite Hydroclimate Conference and the Sequoia and Kings Canyon Science Symposium.
