Coastal sedimentary carbon

Sedimentary carbon

This project seeks to investigate the role coastal sediments play in the long-term storage of carbon. The aims of the project is to refine current sedimentary carbon stock estimates, understand the spatial distribution of carbon on the seafloor, determine the source of the carbon and quantify the rate at which carbon is locked away in these systems. Through an improved understanding of these factors we will be able to provide scientifically robust policy advice on managing and protecting these nationally important carbon stores.
