Short summary
Ocean Alkalinity Enhancement (OAE) is a marine carbon dioxide removal method with large-scale potential. Using an Earth System Model, we explored the effects of continuous coastal OAE application on the seasonal carbon cycle under low and high emissions. We found that stratification retains higher alkalinity over summer, reducing the ocean pCO2 and turning the region into a year-round carbon sink. Additionally, high emissions lower the ocean’s buffering capacity and increase winter CO2 uptake.
