Fig. 3. Evolutions of freshwater transport and salinity.

Decadal mean anomalies in double CO₂ simulations (relative to the climatology in the CTL and ADJ) for freshwater transports ${\mathit{M}}_{\text{ovS}}^{*}$ (light green) and ${\mathit{M}}_{\text{ovN}}^{*}$ (pink) in (A) the CTLCO₂ and (B) ADJCO₂, for (C) $\mathrm{\Delta }{\mathit{M}}_{\text{ov}}^{*}$ in the CTLCO₂ (light blue) and ADJCO₂ (orange), and for (D) the Atlantic basin mean salinity ΔS_Atl in the CTLCO₂ (blue) and ADJCO₂ (red). A 90-year running mean is applied to ${\mathit{M}}_{\text{ovS}}^{*}$, ${\mathit{M}}_{\text{ovN}}^{*}$, and $\mathrm{\Delta }{\mathit{M}}_{\text{ov}}^{*}$ during years 251 to 600, with results shown in thick lines. Smoothed ${\mathit{M}}_{\text{ovS}}^{*}$ (dark green) and ${\mathit{M}}_{\text{ovN}}^{*}$ (purple) are shown in (A) and (B), whereas smoothed $\mathrm{\Delta }{\mathit{M}}_{\text{ov}}^{*}$ is shown in (C), in blue for the CTLCO₂ and in red for the ADJCO₂.
