Extended Data Fig. 4: The trends of CO2 air-sea gradient (∆pCO2).
From: Sea-ice loss amplifies summertime decadal CO2 increase in the western Arctic Ocean
The summer ∆pCO2 vary in the Chukchi Shelf, the Canada Basin, the Beaufort Sea and ice-covered region over the period of 1994 to 2017. The rates of change of ∆pCO2 were computed with monthly mean values (positive rates indicate decrease in ∆pCO2, while negative rates indicate increase in ∆pCO2). The dashed line indicates a complete air-sea gas equilibrium. ANOVA was performed for all regressions. Only ∆pCO2 in the Canada Basin shows a significant trend.
