Critical Zone Observatory

900 675 Stroud Water Research Center

The University of Delaware, in collaboration with Stroud Water Research Center received a $4.3 million grant from the National Science Foundation to establish the Christina River Basin as a “Critical Zone Observatory” for researching questions relating to climate change.

Scientists define the “critical zone” as the portion of the planet from the treetops to the groundwater that sustains terrestrial life.

The Christina River Basin Critical Zone Observatory (CRB-CZO) joined five other such observatories in the United States — based at Pennsylvania State University, the University of Pennsylvania, University of Arizona, University of Colorado, and University of California–Merced. It was funded through a competitive, five year grant awarded by the National Science Foundation (NSF) as part of the American Recovery and Reinvestment Act.
