*
EDOC is defined as the concentration of organic carbon in surface water that can be exchanged with the atmosphere.
**
Negative values indicate net inputs from the atmosphere into the ocean. Net fluxes of OC calculated using alternative parameterisations of k600 are reported as Supplementary Material.
