Fig. 3: Decomposition of CO2-induced Irminger Sea near-surface density changes.

Response of Irminger Sea upper 1000 m depth density to 4xCO2 (δρ; black solid), with contributions from salinity (red) and temperature (blue) changes, as well as their combined effect (black dashed) in a 0.6X and b 1.2X. c Difference between panels b and a. The plots include both the annual timeseries (thin line) and a 9-year moving average (thick line).
