Short summary

The Mauritanian–Cap Vert upwelling is shown to be sensitive to climate change forcing on upwelling processes, which strongly affects the CO₂ surface distribution, ocean acidification rates, and air–sea CO₂ exchange. We confirmed an upwelling intensification, an increase in the CO₂ outgassing, and an important decrease in the pH of the surface waters. Upwelling areas are poorly studied and VOS lines are shown as one of the most significant contributors to our knowledge of the ocean's response.
