Observational estimates of dynamic topography through space and time

M Hoggard, J Austermann, C Randel… - Mantle convection …, 2021 - Wiley Online Library
Earth's mantle undergoes convection on million‐year timescales as heat is transferred from
depth to the surface. While this flow has long been linked to the large‐scale horizontal forces …
