Seagrass meadows are increasingly recognized across the globe as a natural climate solution due to their significant potential in alkalinity-driven carbon dioxide (CO2) removal, which possibly represents an overlooked component of ocean carbon removal. This study comprehensively investigated the carbonate chemistry, sediment carbon content, mineral composition, and benthic alkalinity fluxes in two distinct sites with tropical seagrass meadows: one situated in organic carbon (OC)-rich reef sediments and the other in OC-poor terrestrial sediments.
