The CRB-CZO was active from 2009 to 2013. The CRB-CZO integrated knowledge of water, mineral, and carbon cycles to quantify human impact on Critical Zone carbon sequestration — from soils to sea. It was located in the Piedmont and Atlantic Coastal Plain which provides drinking water to a million people in Delaware and Pennsylvania. CRB-CZO was one of ten NSF-supported critical zone observatories. Data The data archive for CRB-CZO can be found on HydroShare . If you have trouble accessing the data, please email webmaster@stroudcenter.org . Research Experience for Teachers and Undergraduates From 2014–2016, the CRB-CZO and the Susquehanna Shale Hills Critical Zone Observatory (The Pennsylvania State University) jointly hosted National Science Foundation-funded Research Experience for Teachers (RET) and Research Experience for Undergraduates (REU) programs. View the completed research . Publications More than 20 peer-reviewed scientific publications were produced from CRB-CZO research.
