[MITgcm-devel] Re: [MITgcm-support] icebergs

[Dimitris Menemenlis]

Alistair and Jean-Michel, can this really be done?
I was under impression that z* required delZ>>200m?
For Antarctic Bottom Water formation, a really crucial
piece of missing physics is shelf processes.  If we can
model 200m-deep icebergs, we should be able to
model 1000m-ice shelves?
