[MITgcm-support] [EXTERNAL] Question on SHELFICE: ice accretion under ice shelf

[Yilang Xu]

Hi Dimitris,

Great to know the details of pkg/frazil. I missed it at first sight since it was not included in the user manual.
Thank you and Dan for pointing it out.

Best,
Yilang

Dan and Yilang, there is a description of pkg/frazil here:
https://github.com/MITgcm/MITgcm/blob/master/pkg/frazil/frazil_description.tex<https://nam02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgithub.com%2FMITgcm%2FMITgcm%2Fblob%2Fmaster%2Fpkg%2Ffrazil%2Ffrazil_description.tex&data=05%7C01%7Cyxu%40whoi.edu%7C287a932ef1894444c94f08da4761f362%7Cd44c5cc6d18c46cc8abd4fdf5b6e5944%7C0%7C0%7C637900783742881728%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=mGpy07Icg4BaqlySh08eKQxFD1CpuCaXkAeylCC8wsw%3D&reserved=0>
Although the package makes a lot of simplifying assumptions, it will, to first order,
represent frazil ice formation and accretion beneath sea ice and ice shelves.

Cheers, Dimitris

Hi Dan,

Yes there is no linkage between shelfice and frazil. I may look into frazil pkg and check its details.

Just to add that there is a “frazil” package but I’m unsure what it does; and I do not believe it currently interfaces with pkg/shelfice.

Hi yilang

If your question is whether MITgcm represents frazil ice formation and accretion, I do not believe that it does.

Dear MITgcm users,

I have a question on the capability of SHELFICE package. Does the SHELFICE code have the capability to consider refreezing (ice accretion) in the ice shelf cavity or could it be modified to include that? I was looking at some paper on this (e.g., https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2012JC008214) and wondering if MITgcm can model this process.

Thanks,
Yilang
