The potential impact of the uncertainty on final estimates of net carbon removal or storage duration: negligible, low, medium, high, or very high.
Interventions in the surface ocean — like alkalinity enhancement or CO₂ removal — could affect the formation and export of particulate organic carbon (POC). This effect could be quite small if plankton communities are primarily limited by nutrient availability, rather than DIC availability. POC export mediated by calcifying communities could also change in response to changes in biogenic calcification. Data on potential biological responses to removing CO₂ from the surface waters is still lacking.
Added text to reflect that the response of calcifying communities could also impact POC export, and edited for cross-pathway consistency in response to the addition the Direct Ocean Removal Pathway.
