The Susquehanna-Shale Hills CZO consists of an 8-hectare watershed in central Pennsylvania developed entirely on the Rose Hill shale, along with 7 satellite sites referred to as the Shale Transect: 4 developed on Rose Hill shale (New York, Virginia, Tennessee, Alabama), 1 on a stratigraphic equivalent of the Rose Hill formation (Plynlimon, Wales), 1 on a compositional equivalent to the Rose Hill (Puerto Rico), and 1 on a black shale (Marcellus shale, Huntingdon, PA). Research infrastructure in the main Shale Hills catchment includes an array of sensors to quantify water and energy fluxes within the catchment. These sensors provide high-frequency information about the atmospheric, hydrologic, and vegetation dynamics in the catchment. These data, in conjunction with ongoing geophysical, geo- and hydrochemical analyses and geospatial/remote sensing data, inform the ongoing research at the CZO.
The infrastructure at Susquehanna Shale Hills CZO includes physical research equipment and records (field-deployed sensors; sample specimen archives), data systems (time series and geospatial data archives; a wireless network to collect data from field sensors), and logistical support at a main site in central Pennsylvania as well as seven satellite sites. This infrastructure facilitates the ongoing exploration of critical zone processes and can be adapted to the requirements of various research projects. By harnessing existing instrumentation, data and personnel we can identify where future needs exist and respond appropriately. The intensive nature of infrastructure development at the main SSHCZO site has yielded a wealth of information that are now being applied for further studies. Details of the research infrastructure at the main SSHCZO site as well as the satellite sites are provided in this section.

Our interdisciplinary team works collaboratively in one observatory to advance methods for characterizing regolith, to provide a theoretical basis for predicting the distribution and properties of regolith, and to theoretically and experimentally study the impacts of regolith on fluid pathways, flow rates, and residence times.

Sites with constant parent lithology (Silurian Rose Hill Formation) used to study the effects of climate on regolith formation, soil geochemistry, formation and erosion. The sites are operated in collaboration between Penn State and six partner institutions.
