Plenary: "Exploring AIR-WATER-ECOSYSTEM interactions of reactive nitrogen using stable isotope geochemistry"

Thursday, May 11, 2017 - 4:00pm to 5:00pm
14 Earth-Engineering Science Building

On Thursday, May 11th, at 4:00 p.m. in 114 Earth-Engineering Science Building, Dr. Emily Elliott, Associate Professor of Geology & Planetary Science, University of Pittsburgh, will be presenting a plenary at the 2017 Susquehanna Shale Hills Critical Zone Observatory All-Hands Meeting at Penn State. 

Dr. Elliott will present the plenary  "Exploring AIR-WATER-ECOSYSTEM interactions of reactive nitrogen using stable isotope geochemistry." 

Nitrogen (N) distributions in the Earth’s atmospheric, terrestrial and aquatic systems are tightly coupled with human activities.  Although N is an essential building block of life, in excess nitrogen is a major factor in the degradation of air and water quality with important implications for ecosystem and human health.  This presentation will demonstrate the utility of using stable isotope N biogeochemistry to address key challenges at the heart of the water-ecosystem-society nexus.  I will describe several examples of our work that examine the coupled relationships between human activities on N distributions and dynamics in urban, forested, and agricultural systems.  Together, this body of work ultimately aims to determine how best to manage inputs of N to protect ecosystem and human health, water and air quality.

Dr. Emily M. Elliott is an Associate Professor in the Department of Geology and Environmental Science and an Adjunct Associate Professor in the Department of Civil and Environmental Engineering at the University of Pittsburgh.  Prior to joining the University of Pittsburgh in 2007, she was a Postdoctoral Researcher with the U.S. Geological Survey, Water Resources Division.  She earned her M.S. and Ph.D. in the Department of Geography and Environmental Engineering at Johns Hopkins University in Baltimore, MD and her B.A. in Environmental Science at the University of Virginia in Charlottesville, VA.
