Sea level rise is occurring at a significantly higher rate in coastal Louisiana than at most of the world’s coastal communities. The combined effects of global sea level rise and regional subsidence, or sinking, contribute to Louisiana’s 13-millimeter-per-year relative sea level rise rate.
LSU Department of Oceanography and Coastal Sciences Professor John White, Assistant Professor Zuo “George” Xue, LSU Department of Chemistry Professor Robert Cook and University of Central Florida Biology Assistant Professor Lisa Chambers have been awarded a grant by the National Science Foundation to study the “Fate of Coastal Wetland Carbon Under Increasing Sea Level Rise: Using the Subsiding Louisiana Coast as a Proxy for Future World-Wide Sea Level Projections.”
The study aims to increase our understanding of the magnitude of carbon from soil being returned to the atmosphere relatively quickly. Field and laboratory data will be combined with existing information on wetland loss rates to drive a coupled physical-biogeochemical model of the carbon and nitrogen budget for the Barataria basin. Results of the study will help build more accurate predictive modeling for future climate change predictions.
