Regarding paleoclimate and ice sheet modelling - paleo configurations of the Antarctic Ice sheet are potentially fruitful constraints on the model physics etc of ice sheets and interactions with the rest of the earth system - particularly with the ocean which is a strong driver of Antarctic ice sheet due to its largely marine-terminating boundary .
The resolution requirements for ocean modelling in ice-shelf cavities was raised.
There are already finer resolution versions of major ocean models like MITgcm, NEMO and ROMS being used in that situation.
The development of generalized vertical coordinates in MOM6 might also be relevant. In fact most current ice sheet-shelf modelling is using a rather simple parameterization of ocean driven basal melting. The transport of heat by the ocean across the continental shelf also requires high resolution modelling. I suspect that support for nested resolution in the ocean model would be a more palatable approach than implementing a separate model of the Antarctic (or any other) coastal ocean.
