Fig. 2

a Vertical distribution of the temperature above the in situ freezing point (Tf) across PIB (left panel) and along the PIIS front (right panel, IF line) in 2020. The 27.47 kg/m3 and 27.75 kg/m3 (potential density) isopycnals in 2009, 2014 and 2020 are indicated by solid purple, green and black lines, respectively. Dashed black lines denote the simulated depths of the 27.47 kg/m3 and 27.75 kg/m3 isopycnals in 2020 (Methods). b Same as in a, but this panel shows the meltwater fraction in 2020. Blue contours indicate a 10‰ meltwater fraction. Values at depths with unreliable meltwater fractions were excluded (Methods).
