Workshop 2: Future Directions in Synchrotron Environmental Science Co-organizers: Steve Sutton, Ken Kemner, and Shelly Kelly The purpose of the workshop is to evaluate future directions in environmental science amenable to experimentation with synchrotron radiation. The intent is to focus on frontier science and to evaluate the science-driven requirements for future instrumentation. Although the focus will be on research opportunities at the APS, this will not be a strict limitation. The outcome will be a summary to be submitted to the committee on "Future Scientific Directions for the Advanced Photon Source" chaired by G. Shenoy and S. Sinha.
