Earth’s mantle composition revealed by mantle plumes
Map generated with SubMachinne: velocity anomaly (δVS/VS) on a tomography slice from the lowest mantle at 2,800-km depth, extracted from the SEMUCB-WM1 model.

Changes in core–mantle boundary heat flux patterns throughout the supercontinent cycle
Temperature distribution in a slice in 2600 km depth through all models at the end of the simulation (present-day). Bottom left-hand panel shows the S-wave velocity anomaly of the seismic tomography model SEMUCB (French & Romanowicz 2014) in the same depth slice for comparison. Yellow colours in the other panels indicate seismically slow regions (dv/v < 0.1 per cent) in SEMUCB.

Synchronous motion of the Easter mantle plume and the East Pacific Rise
Figures were generated using ‘SubMachine’: The vertical column of panels on the left side are DETOX-P2 vertical sections (A–G) down to the LLSVP (2800 km).
