Abstract Coastal wetlands are important for their ability to regulate global climate through the sequestration and long‐term storage of carbon. Accurate quantification ecosystem‐specific carbon dynamics (including sequestration, storage, fluxes) is needed develop accurate budgets that inform change mitigation. Most work quantify either use subsampling in core habitats or benefit transfers upscale values. While these approaches valuable, our understanding across ecosystem transitions overall heterogeneity remains a critical gap coastal ecosystems as boundaries not always clear. In this study, we established transects both mangrove seagrass ecotones into adjacent tidal flats Singapore quantifying vegetation cover, soil CO 2 fluxes. Vegetation cover all most followed decreasing sigmoidal pattern from vegetated unvegetated portions, but differed rate width. fluxes peak distribution mangrove–tidal flat with maximum values occurring within mangroves were correlated pneumatophore density, while seagrasses saw linear increase flat. Seascape analysis showed site‐specific impacts resulted differences stocks (0%–8%) well width transitions. This study highlights importance better account edge effects, which can lead over under estimation carbon, provides step increasing accuracy blue assessments ecosystems.
