The ocean absoirbs approximately one-third of anthropogenic C02 emissions (Friedlingstein et al., 2022), which :plays a crucial role in climate regulation, but modifies marine carbonate chemistry. This increase in C02 uptake has led to a long-term decrease in ocean pH, a phenomenon known as ocean acidification (OA; Caldeira and Wickett, 2003). Since pre-industrial times, the pH of the global ocean surface has decreased by 0.1 units, representing a 30% increase in acidity (Caldeira and Wickett, 2003). Anthropogenic C02 uptake and storage (Cant) in the ocean has significant spatial variability, so regional studies of OA rates are needed (Sabine et al., 2004). This study analyzes the evolution of ocean acidification of the main water masses of the Iberian basin which is part of the North Atlantic, a major oceanic for the sjnk of Cant (Gruber et al., 2019)
