Fig. 6. Time series of GMSL after WAIS collapse for different Earth models and melt geometries.

(A) Evolution of GMSL for four simulations of sea level change driven by WAIS collapse scenario PSU3D1 (Fig. 2F) (17). Each simulation adopts a different viscoelastic Earth model. Solid, dashed, and dotted blue lines: Earth models V3D_SD (Fig. 2, A and B), V3D_SD+, and V3D_SD–, respectively (see Sensitivity tests). Solid purple line: Earth model V3D_RH (Fig. 2, D and E). (B) Evolution of GMSL due to uplift of marine-based sectors for five scenarios of WAIS collapse taken from (17), as labeled, and the 3D viscoelastic Earth model V3D_SD (Fig. 2, A and B). The GMSL computed without the outflux mechanism (i.e., without uplift of exposed marine-based sectors) for each simulation is listed in the legend.
