OS3.3

Occupying only 0.2% of the ocean surface area, coastal vegetated habitats (including saltmarshes) contribute 50% of global carbon (C) burial in marine sediments. These habitats bury C at a greater rate and store more C per unit area than their sub-tidal and terrestrial counterparts. Blue Carbon habitats therefore provide a globally significant climate regulation service by sequestering CO2 through burial and long-term storage of C. We invite contributions which explore the wealth of processes which contribute to this long-term storage of C and which highlight the value of Blue Carbon habitats in the accounting of global C burial.
