Short summary
This study quantifies particulate organic carbon export and peatland lateral degradation along the northern coast of Bengkalis Island, Indonesia, using field surveys and remote sensing. Estimated fluxes ranged from 2.06 to 7.60 tC m-1 yr-1 due to coastal erosion and 1.43 to 5.41 tC m-1 from peat mass movement events. These results reveal a new carbon export pathway from tropical peatland coasts to marine environments, highlighting the role of coastal processes in the global carbon cycle.
This study quantifies particulate organic carbon export and peatland lateral degradation along...
