Abstract
Changes to the Greenland and Antarctic ice sheet over recent decades have contributed to sea-level rise at an accelerating rate and present the largest potential for future changes in sea-level. Accurate sea-level projections require simulations of ice sheet evolution using next-generation ice sheet models coupled to Earth-System Models (ESMs), but current limitations prohibit such projections. SciDAC's ProSPect focuses on ice sheet and ESM improvements in three main areas: 1) ice-sheet model physics and coupling, 2) initialization and uncertainty analysis, and 3) ice-sheet model performance on next-generation, high-performance computing (HPC) architectures. In this poster, we present recent advancements under ProSPect in the area of ice sheet model physics.
