DI010:
Linking interior evolution, dynamics, and surface signatures across planetary scales





Session ID#: 25750

Session Description:
Measurements of the deep interior cannot be made directly but surface measurements such as gravity, topography, volcanism, and sea-level, give insight into the motion inside. These measurements provide necessary constraints on the mechanisms governing the dynamics of the deep interior, from relatively small scales, such as those linked to mantle plumes, to the longest planetary wavelengths. Earth's present-day surface is a snapshot in time that displays the integrated signal of multiple processes that operated at different times with varying intensity and duration. The same is true of other planetary surfaces. Linking such temporal and spatial scales is thus crucial to understanding planetary history, not only on Earth, but also on other planetary bodies.

This session aims to shed light on these spatial and temporal links using multiple approaches including mantle flow modelling, seismology, data inversion and others. We welcome theoretical, numerical, laboratory and observational contributions from all relevant disciplines.
