About the research project
Deep learning with artificial neural networks has evolved rapidly and become a widely applied tool for the study of Earth surface processes (Reichstein et al. 2019). In glaciology, such applications have recently been used to make highly resolved topographic realisations of bedrock and water pathways beneath ice sheets (MacKie et al. 2020). Related applications have also advanced our understanding of subglacial geology and geothermal heat flow in Antarctica where observations are scarce (Stål et al. 2021). More recently, neural networks have been used to emulate physical glacier models with significant computational advantages (Jouvet et al. 2022). This project combines glaciological research in IMAS and the Compute Antarctic group in the School of Natural Sciences, with the aim of improving our understanding of the basal interior of the East Antarctic Ice Sheet. The work will involve artificial neural networks trained with observational data from Antarctica as well as outputs from numerical ice sheet models.
The overall aim of the research is to understand how the East Antarctic Ice Sheet is shaped and influenced by the largely unknown continent beneath it. The work is specifically designed to resolve the flow of water at the ice-bed interface (Mackie et al. 2020), the distribution of soft sediments connected to deep groundwater systems (Christoffersen et al. 2014), and the formation of temperate basal ice with low viscosity (Law et al. 2023). With a broad scope and focus on drainage basins across East Antarctica, the research will identify poorly understood factors that control the flow of ice on timescales ranging from decades to centuries.
