[MITgcm-devel] SEAICE_rhoIce

[Jean-Michel Campin]

Hi Dimitris,

The usual way to proceed would be to change the default
and to add the old value:
 SEAICE_rhoIce=910.
in the data.seaice of exp global_ocean.cs32x15.icedyn.

the advantages are:
 - show how to reproduce the old results (and check that it
   really does)
 - avoid (for some time) to regenerate a new output.txt

And in this particular case, there is no real inconsistency for 
this exp. which does not use the thermodynamics part.
