Extended Data Fig. 5: Viscosity plots for the wider North Sea region.
From: Global sea-level rise in the early Holocene revealed from North Sea peats

They display viscosity at four depths (a-d), as used in the 3D GIA model SM9925. The figure illustrates the spatial variation of the viscosity profile. The squares (white in panel a, blue in panels b-d) denote the SLIP data sites used in this study.
