Title
Modelling Ice Sheet Changes in the Wilkes Subglacial Basin before 2500: How Sensitive Are Our Predictions?
About
The Wilkes Subglacial Basin (WSB) holds the largest volume of marine-based ice of any Antarctic basin and, due to its susceptibility to Marine Ice Sheet instability (MISI), has a potentially significant impact on future sea level rise. Accurately predicting the WSB’s ice sheet dynamics is not only crucial but also technically challenging, given the extreme sensitivity of ice sheet models to various configurations. In this study, we employ the Elmer/Ice model, based on the Shallow Shelf Approximation (SSA), to investigate the sensitivity of the WSB’s ice dynamics and mass loss to various future climate forcings and model settings. These span varied considerations including basal friction laws, mesh resolutions, and basal melt parameterizations both beneath the ice shelves and at the grounding line. Through this study, we aim to shed light on how model configurations influence ice mass loss projections, offering valuable insights for refining future ice sheet predictions.
