As the global temperature continues to increase, carbon dioxide (CO₂) is a major driver of this global warming. The increased CO₂ is mainly caused by emissions from fossil fuel use and land use. At the same time, the ocean is a significant sink in the carbon cycle. The North Atlantic is a critical ocean region in reducing CO₂ concentration. We estimate the CO₂ uptake in this region based on a carbon inverse system and atmospheric CO₂ observations.
