Abstract
Sea-level rise from shrinking glaciers and ice sheets is increasing. Observed acceleration in the rate of contribution from Greenland and Antarctica Antarctic ice sheets is a concern, particularly for West Antarctica where the ice sheet’s geometric configuration is might be unstable to small perturbations.
ProSPect addresses goal is to address 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 (inadequate or missing physics, couplings, model initialization, validation and uncertainty quantification) that prevent accurate 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 overall computational efficiency and portability of the model efficiency (adaptive mesh refinement, solver preconditioners and , performance portability).
