Exploring the shallow water carbon pump in the Gulf of Mexico

Scientists from ODU and WHOI are at the Florida State University Coastal Marine Laboratory this summer to study the role of seagrasses in sequestering carbon in the shallow waters of the Gulf of Mexico.  The team led by Drs. Zimmerman and Burdige of ODU, and Dr. Matt Long from Woods Hole Oceanographic Institution, are utilizing cutting-edge methods for measuring photosynthetic oxygen and carbon exchange (Eulerian and eddy covariance techniques) combined with sediment geochemistry measurements to build and test numerical models that can be scaled up to quantify the dynamics of carbon flux in seagrass meadows.
