Fig. 2: Iceberg melt rates and freshwater flux.
a Relationship between runoff (Qr) and domain-averaged submarine iceberg melt rate and total iceberg freshwater flux (Qfw). b Horizontally averaged iceberg freshwater flux profile, coloured by runoff, for the ‘channelised’ runoff configuration and standard melt rate parameter values. The dashed horizontal red line in b donates the 27.3 potential density contour, approximating the depth of the interface between Polar Water and Atlantic Water. In a, the blue lines indicate simulations with standard melt rate parameter values, whilst the green lines indicate simulations with adjusted melt rate parameter values (Methods; Supplementary Table 1). The solid lines represent our ‘channelised’ drainage scenario and the dashed lines represent our ‘distributed’ drainage scenario.
