WebAbstract. Mass loss due to dynamic changes in ice sheets is a significant contributor to sea level rise, and this contribution is expected to increase in the future. Numerical codes simulating the evolution of ice sheets can potentially quantify this future contribution. However, the uncertainty inherent in these models propagates into projections of sea … Web25 optimisation techniques.

WebIn some cases, this uncertainty may be exogenous to the dynamics of the ice sheet model: for instance, uncertainty in ocean-driven ice shelf melt, while a likely important contributor to ice-sheet projection uncertainty (Robel et al., 2024), arises from incomplete knowledge of the ocean system rather than the dynamics of the ice model itself.
