Global dynamic topography observations reveal limited influence of large-scale mantle flow

MJ Hoggard, N White, D Al-Attar - Nature Geoscience, 2016 - nature.com
Convective circulation of the Earth's mantle maintains some fraction of surface topography
that varies with space and time. Most predictive models show that this dynamic topography …
