The contribution to sea-level rise from shrinking glaciers and ice sheets is increasing. Observed acceleration in the rate of ice loss from the Greenland and Antarctic ice sheets is a concern, particularly for the West Antarctic Ice Sheet (WAIS) where much of the ice sheet is , which is largely grounded below sea level and the ice sheet’s . This geometric configuration might be unstable to small perturbations.makes it susceptible to a dynamic instability that could result in catastrophic collapse as a result of relatively small perturbations at the ice sheet's margins. While Ice sheet models have become significantly more advanced over the past decade they are still incomplete in many ways, and thus lead to large uncertainties when applied towards projections of future sea-level rise. The goal of the ProSPect SciDAC partnership is to address the current limitations of the to DOE ice sheet and Earth system models (that limit their use for making accurate sea-level projections. These include inadequate or missing model physics, incomplete couplings between models, and deficiencies methods for model initialization, validation, and uncertainty quantification) that prevent accurate sea-level projections.In this poster we present recent developments of the ice sheet models . This poster focuses on recent efforts under ProSPect towards ice sheet model development to incorporate missing physics (ice - damage, fracture, and, calving, subglacial hydrology, and enthalpy) and to improve the overall computational efficiency and portability of the models (adaptive mesh refinement, solver preconditioners, and performance portability).
