Fig. 2: Volume changes during 100-year melt perturbation simulations for the Filchner–Ronne, Ross and Amundsen Sea Embayment catchments.

a, Shaded red shows the total loss of ice above flotation in meters water equivalent (m w.e.) after 100 years in the NEMO4 perturbed simulation using the modern analogue technique melt (Mmat) parameterization. Coloured lines (legend in b) show the final 100-year grounding line positions for all perturbed simulations. Control simulations are in black. Line styles (shown in the legend in c) denote the melt rate parameterization (see Methods). Gl, glacier; IS, ice stream. b–d, Sea-level equivalent (SLE) volume loss (negative value indicates sea-level rise) for the Filchner–Ronne, Ross and Amundsen Sea Embayment catchments using the same line colour and styles outlined above.
