[MITgcm-support] Too large of Sea Ice

Hi All,
I am running a circumpolar antarctic model at 1/12 degree and I keep getting so thick of sea ice it throws an r* error. I can get it to be thin enough using ice diffusion but physically that seems dubious. I have also tried the work arounds in the documentation 8.6.2.7 changing the SEAICEpressReplFac <http://lxr.mitgcm.org/lxr2/ident/MITgcm?_i=SEAICEpressReplFac> = 0; and even the SEAICE_CAP_ICELOAD. Changing the former didn’t seem to have an effect. Changing the latter didn’t seem to change the h_eff max value I have been following in the STDOUT. Files. I have attached the data.seaice file. Do you all have any advice on how to solve this issue? I have looked at the output and it is not just that I have weird ponds with sea ice that is too thick, it is too large in entire embayments that should be able to flush.
Thanks,
Madeleine
