Extended Data Figure 8 : Linear resolution analysis for synthetic ‘hanging’ plume input structures in the upper mantle and transition zone.

Extended Data Figure 8

This figure is similar to Extended Data Fig. 7, but now examines recovery beneath Iceland. Upper panels, hanging-plume input models. Lower panels, output models when inputs are placed beneath Iceland. The retrieved structures are again quite symmetrical and exhibit the appropriate depth extent, although amplitude recovery is slightly less impressive than that observed beneath Hawaii (consistent with the results of Extended Data Figs 4 and 5).
