Dear MOM community,
Recently we've completed an offline coupling of MOM5 to the ice sheet model PISM in an ocean-sea ice - ice sheet only setup (GMDD - Coupling framework (1.0) for the ice sheet model PISM (1.1.1) and the ocean model MOM5 (5.1.0) via the ice-shelf cavity module PICO) however there was a caveat with this approach - we inserted the mass and energy fluxes from the sub-shelf melt into the ocean via the river runoff module. As we are now upgrading to MOM6, the aim is to do this properly and provide a 3D field of mass and energy fluxes to MOM at the correct depths.
My question then (particularly to the developers), is what would your recommendation be in going about this (or has anyone thought about this problem in the CESM community?)? I know that the coupler has a 3D data override structure, but no fields for ice shelf melt. Furthermore, the mass fluxes need to be inserted in such a way that allow dynamic sea level change (currently any runoff/ synthetic mass flux is necessarily cancelled out at the coupler level to avoid spurious mass drift due to it being an ocean-sea ice only configuration).
Cheers,
Willem
