Led by the Alliance’s Climate Intern, Paula Sternberg, this project compared different methods used to measure belowground carbon in mangrove ecosystems. Currently, there is no standard tool or methodology for measuring belowground carbon across scientific studies. Oftentimes, studies measure carbon to different depths using various coring techniques. This project compared tools, techniques, and methodologies for the assessment of total carbon in mangrove forests, with the goal of facilitating carbon estimates for mangrove blue carbon studies.
