Funded by the National Science Foundation, eight REU/RET participants with Susquehanna Shale Hills Critical Zone Observatory joined seven participants with Christina River Basin Critical Zone Observatory (CRBCZO) for orientation at Penn State. Initial days introduced critical zone science, field techniques, and explored the Shale Hills and Garner Run catchments. The cohort then traveled to Stroud Water Research Center (SWRC) for orientation which included field tours of the Christina CZO, laboratory tours at SWRC, as well as a sensor workshop. Participants will engage in critical zone research projects for the remainder of the program, working closely with their faculty mentor. The program will culminate in a oral/poster presentation session and attendance at the Ecological Society of America Annual Meeting, Baltimore, MD.
