Short summary

In this study, we investigate the evolution of CO₂ uptake and ocean acidification in the North Atlantic Subpolar surface water. Our results show an important reduction in the capacity of the ocean to absorb CO₂ from the atmosphere (1993–2007), due to a rapid increase in the fCO₂ and associated with a rapid decrease in pH. Conversely, data obtained during the last decade (2008–2017) show a stagnation of fCO₂ (increasing the ocean sink for CO₂) and pH.
