Marine macrophyte biomass production, burial, oxidation, calcium carbonate dissolution, and metabolically accelerated diffusion of carbon dioxide across the air-sea interface may combine to sequester at least 109 tons of carbon per year in the ocean. This carbon sink may partially account for discrepancies in extant global carbon budgets.
