Coupling Solid-Aqueous-Gas Phases Of Carbon And Nitrogen Across Topographic Gradients And
Extreme Weather Events
Rodrigo VargasDepartment of Plant and Soil Sciences
To understand how weather variability (especially extreme weather events) influences the key ecosystem processes of nutrient and soil GHG fluxes in ex-urban forests.
Approach:- In situ field measurements across topographic gradients- Experiment of extreme water pulses on soils- Automated measurements of multiple soil GHG
Motivation
Hurricane Matthew (2016)
Hurricane Sandy (2012)
(Dhillon and Inamdar 2013)
(Vargas 2012)
Conceptual diagram of how topographic position will influence GHG fluxes, soilwater content, C and N pools, and variance. The size of the symbol represents the relative magnitude of the variable
