Improved understanding of temporal trend in observed surface water pCO2 in the North Atlantic

Global ocean carbon models and available syntheses of the oceanic CO2 flux suggest that the North Atlantic sub-polar gyre (50°N-70°N, 80°W-10°W) is a region of increasing uptake of CO2 from the atmosphere, with the oceanic partial pressure of CO2 (pCO2) increasing more slowly than the atmospheric CO2 over time. The UEA analysis of available CO2 data shows that, on the contrary, seawater pCO2 has increased faster than the atmosphere in recent decades, especially in summer, resulting in a decrease in uptake from the atmosphere. A decrease in the biological productivity of the region may be the underlying cause of this trend. From the observed trend UEA estimated a significant decrease in the annual carbon uptake in this region.
