[MITgcm-support] internal barrier/boundary for SEAICE

[Martin Losch]

Hi Dan,

I am afraid not. What’s worse, I have somewhat inconsistently replaced the internal mask of the seaice model (HEFFM) by maskC in many places (but not all), so that you can’t even use a modifed HEFFM to do what you want. You could, as a hack, use the bottom drag parameterization for fast ice to impose fast ice, e.g. by modify CbotC in seaice_bottomdrag_coeffs.F to reflect your geometry.

Such a thing would be for the purpose of imposing e.g. an ice tongue that blocks the flow of sea ice but does not impose any forcing (or weight) on the ocean.
