Abstract
To date and to our knowledge, no climate models have included explicit static sub-ice-shelf cavities and associated calculation of sub-ice-shelf heat and moisture fluxes as part of coupled simulations. Inclusion of ice shelf cavities and associated processes is (1) a critical first step towards full coupling of the marine-based Antarctic Ice Sheet and (2) a unique scientific capability in its own right.
...
The capability has been tested in a realistic configuration via both G-compset and B-compset simulations, with preliminary analysis suggesting the implementation of static ice shelf cavities is correct. G-compset and B-compset simulations are ongoing to address fundamental questions related to numerical stability, equilibration/variability time scales, resolution dependence, and, ultimately validation against extant observational datasets in preparation for application to ice-shelf-cavity-related climate science. In addition to opening a door to an exciting new realm of coupled climate science, this work will provide the basis for further development associated with a full coupling of the marine-based Antarctic Ice Sheet within the ACME climate model.
This poster focuses on the coupling, mapping files, and interaction between components. The submission #26 Ocean Cavities Below Ice Shelves is on the numerical methods required to support sub-ice shelf cavities within the ocean model.
