The Calhoun Critical Zone Observatory (CZO): A Time Machine and Environmental History Laboratory

Thursday, April 24, 2014 - 3:45pm

Dr. James Giesen, Mississippi State Department of History

Dr. Daniel Richter, Duke University Department of Soils and Forest Ecology

Petigru 212

Please join the History Center and the School of Earth, Ocean and Environment on Thursday, April 24 in Petigru 212 (3:45-5:00) for a unique interdisciplinary seminar about the Calhoun Critical Zone Observatory (CZO), featuring the work of soil scientist Dan Richter of Duke University and historian James Giesen of Mississippi State. 

Everyone is also invited to attend Tom Lekan’s History 700 seminar that same day, 9:30-12:00 in Green Quad Learning Center 101, where we will discuss readings related to the CZO and the work of Professors Richter, Giesen, and USC geography professor Allan James.  These readings are available below



Fifteen scientists and humanities scholars seek to understand how Earth’s Critical Zones respond to and recover from land degradation and severe erosion.  Re-instrumented catchments help quantify the evolution in the hydrology and biogeochemistry of arable land that was historically subject to accelerated erosion and deposition.  Given that land is an integrated system from plant-canopies through soils to water in deep aquifers, Calhoun research focuses on how land use stresses the networks that connect the land’s surface and subsurface subsystems.  Researchers are using historic and contemporary data of vegetation, soil, catchments, hydrology, and sensor networks to hindcast and forecast Critical Zone evolution across temporal and spatial scales.
