Fig. 5: Southern Ocean mixed-layer depth and sea-ice concentration.
From: Regional conditions determine thresholds of accelerated Antarctic basal melt in climate projection

a–c, The climatological maximum of monthly mixed-layer depth in ICE-HIST (a) and CORE-HIST (b) simulations and the difference between ICE-HIST and CORE-HIST (c). d–f, The September sea-ice concentration in ICE-HIST (d) and CORE-HIST (e) simulations and the difference between ICE-HIST and CORE-HIST (f). Mixed-layer depth (MLD) is defined by the 0.03 kg m−3 density difference criterion. The results are averaged from 1851 to 1899.
