Blue carbon loss

Our dataset includes paired reports of soil Corg stock from both disturbed and intact blue carbon ecosystems (BCEs) from 95 mangrove sites, 35 saltmarsh sites, and 36 seagrass sites worldwide. We categorized disturbances into those causing deep soil disruption—such as the conversion of mangroves and saltmarshes to agriculture or aquaculture and dredging of seagrass meadows—and those causing minimal soil disruption, including mangrove clearance, saltmarsh grazing, and general degradation of BCEs.
