SusquehannaShale Hills Critical Zone Observatory The SusquehannaShale Hills
Susquehanna/Shale Hills Critical Zone Observatory The Susquehanna/Shale Hills CZO is a 5 year research effort to create an environmental observatory for the study of the pathways and rates of water, solutes, and sediments in the Shale Hills Watershed within the Penn State Experimental Forest. The Shale Hills CZO brings together 6 transect sites and multiple disciplines engaged in research on bedrock to atmospheric boundary layer processes in the “critical zone”. The focus of this multidisciplinary NSF-funded research effort is to quantitatively predict the creation, evolution, and structure of regolith as a function of geochemical, hydrologic, pedologic, biologic, and geomorphologic processes.
