The subduction reference framework: Unravelling the causes of long-term sea-level change

Project Summary
Sea level has fluctuated by up to 300 m through geological time, creating vast sedimentary basins and associated natural resources. We will use Earth’s subduction history as imaged by seismic tomography to establish a subduction reference framework for the past 200 million years, tracking all tectonic plates in both latitude and longitude. 4D numerical mantle-plate tectonic simulations (3D plus time) will reconstruct how the recycling of old, cold oceanic plates into the mantle have influenced surface topography and sea-level change since the breakup of the supercontinent Pangaea.
