Understanding ice sheet-ocean interaction is a key-point to quantify future sea level rise.  A recently published article presents FISOC (Framework for Ice Sheet-Ocean Coupling), which is an open-source tool based on ESMF (Earth System Model Framework) that allows for coupling different ice-sheet model and ocean model components. FISOC allows fully synchronous coupling, in which both ice and ocean run on the same time step, or semi-synchronous coupling in which the ice dynamic model uses a longer time step. Multiple regridding options are available, and there are multiple methods for coupling the sub-ice-shelf cavity geometry. Also, thermodynamic coupling is an option.The approach is modular, meaning that any ESMF-compliant ice-sheet or ocean model can be coupled using FISOC. Elmer/Ice includes an application interface (API) to FISOC and has been used in the current article to demonstrate the capabilities of the framework along the lines of simplified setups.
