Fig. 3: Antarctic contribution to Pliocene sea level in best-fit model simulations.

From: Geologically constrained 2-million-year-long simulations of Antarctic Ice Sheet retreat and expansion through the Pliocene

Fig. 3

a Best-fit model runs (see Fig. 2 for model-data evaluation) simulate large-scale Antarctic ice sheet fluctuations of up to ~20 m esl (contribution to global sea level). b Orbitally resolved CO2 proxy cf. ref. 103, constrained by boron CO2 reconstructions. c January insolation anomaly at 80°S. Grounding line positions through time are plotted for best-fit runs d OC2-HFmedhi-vol and e OC2-HFmedlo-area, showing the spatial variability of the ice sheet ranging from grounded ice expansion across the continental shelf to collapse of all marine-based ice.
