The mission of SEES (Synchrotron Earth and Environmental Science) is to advance research and education in synchrotron-based Earth and environmental science to better understand our planet from the atmosphere to the core, to address societally relevant problems, and to train the next generation of scientists. SEES is responsible for the management, operation, and development of multiple user facilities hosted at four DOE-operated US synchrotrons: Advanced Photon Source (APS), Advanced Light Source (ALS), National Synchrotron Light Source II (NSLS-II), and Stanford Synchrotron Radiation Lightsource (SSRL).
2025 SEES-ISRD Joint Meeting
SEES and ISRD invite you to attend our annual meeting to be held jointly at the University of Chicago on August 11-13, 2025. Keynote speakers will discuss topics in rock and mineral deformation and rheological properties in Earth, and there will be a poster session with a broad scientific focus. All SEES and ISRD researchers are welcome and encouraged to attend. Click here to learn more.
