Sensitivity of Antarctic Bottom Water Formation and Export to Horizontal Model Resolution
Dense Shelf Water formation decreases when the model resolution is refined from 1/10° to 1/20° to 1/40° due to shelf freshening
Antarctic Bottom Water export increases with finer model resolution...

We conclude that a horizontal resolution of 1/10° is sufficient to simulate AABW export from East Antarctica, but finer resolutions of up to 1/40° increase the offshore transport and may be required to resolve the AABW export in the Weddell and Ross Seas.

The total offshore AABW transport increases, however, with increasing model resolution, especially across the 2500m isobath, due to less diapycnal mixing during the downslope flow. This resolution dependency is strongest in the Ross and Weddell Seas, the two most important regions of AABW formation.

This resolution dependency is strongest in the Ross and Weddell Seas, the two most important regions of AABW formation.
The formation of Dense Shelf Water, the precursor of AABW, reduces with increasing model resolution due to
shelf freshening. Increased eddy activity with higher model resolution flattens the isopycnals in the open Southern Ocean and enables access of lighter waters onto the continental shelf.
