Short summary

We empirically show that not only suspended-particle trapping but also the direct supply of belowground seagrass detritus can be the dominant organic carbon enrichment pathway of seagrass sediments. The relative importance of these two pathways may depend on the belowground biomass productivity. Our work identifies a previously overlooked factor controlling the carbon sink capacity of seagrass meadows and contributes to more precise estimates of global blue carbon stocks.
