Abstract
Sea-level rise from shrinking glaciers and ice sheets is increasing. Observed acceleration in the contribution from Greenland and Antarctica is a concern, particularly for West Antarctica where the ice sheet’s geometric configuration is unstable to small perturbations.
ProSPect addresses the limitations of the DOE ice sheet and Earth system models that prevent accurate sea-level projections. Focus areas include (1) missing or inadequate model physics, (2) missing ISM and ESM coupling, (3) coupled ISM and ESM initialization methods, and (4) probabilistic sea-level projections.
In this poster we present recent developments of the ice sheet models to incorporate missing physics (ice-damage, calving, subglacial hydrology, enthalpy) and to improve the model efficiency (adaptive mesh refinement, solver preconditioners and performance portability).
