Short summary

Intertidal seagrass meadows are often considered important blue carbon ecosystems, but their role in highly dynamic environments is uncertain. Using a coupled hydrodynamic–ecosystem model, we quantify carbon uptake, burial, and export in a Wadden Sea tidal basin. We show that sequestration rates are low, depend on meadow persistence, and that a substantial fraction of seagrass carbon is redistributed within the basin and to salt marshes.
