Long-term global sea level fluctuations have been a driving force of biogeography, climate change and organic evolution. We will assimilate images of subducted tectonic plates in the Earth's mantle into geodynamic models to establish a novel Subduction Reference Frame for the past 200 million years. This will form the basis for unravelling the effects of subduction on surface topography and sea-level change. The project outcomes will include predictive models of sedimentation and erosion in continental interiors, and will transform knowledge about the nature and magnitude of natural planetary change.

长期的全球海平面波动是地理学、气候变化和生物进化的驱动力。我们将把地幔中俯冲构造板块的图像同化到地球动力学模型中，以建立一个新的过去2亿年的俯冲参考框架。 这将成为揭示俯冲作用对地表地形和海平面变化影响的基础。该项目的成果将包括大陆内部沉积和侵蚀的预测模型，并将改变有关地球自然变化的性质和幅度的知识。
