Fig. 7: Percentage perturbation shear wave speed at each station with respect to the average at each depth slice.
From: Uppermost crustal structure regulates the flow of the Greenland Ice Sheet

The colours of the upright triangles are the δVs percentage perturbation values calculated at that station. The squares are stations that match LITHO1.0. The smaller inverted triangles are the range of Vs taken from the 20% ensemble models. For on-ice stations, the ice-sheet layer has been removed.
