[MITgcm-devel] SEAICE_rhoIce

[Jean-Michel Campin]

Hi,

I agree with those changes, except may be the 
multicategory: unfortunately, it's not a run-time parameter,
and would require to change SEAICE_OPTIONS.h.
And it's not presently tested, so I would prefer to 
move in 2 steps:
1) have this multicategory seaice tested first.
2) and then see what the default should be. But the 
   best solution would be to have a run-time parameter.
