  "abstract": "One potentially scalable method to remove CO ₂ from the air is ocean alkalinity enhancement (OAE), which works to lower the ocean's CO ₂ partial pressure ( p CO ₂ ) and accelerate CO ₂ sequestration and durable storage. This study explores how OAE might affect the seasonal carbon cycle, which plays a key role in the ocean's annual CO ₂ uptake. By analysing Earth System Model simulations of OAE implemented continuously at the European coastline under low and high emissions, it was found that: (a) due to surface alkalinity retention, OAE reduces ocean p CO ₂ most strongly in summer, turning the region into a year-round carbon sink; (b) the strongest air-sea CO ₂ uptake enhancement takes place in winter; (c) the ocean's carbon sink is increased more strongly in SSP3-7.0 than in SSP1-2.6 due to a lower buffering capacity.",
