[MITgcm-devel] seaice

[Martin Losch]

Hi Dimitris,

as Jinlun points out, the code is still not really fit for general  
curvilinear coordinates. I overlooked a few abbreviations that were  
used with the spherical coordinates in mind. But now your hacks in  
seaice_init are not necessary anymore, except for the maybe the mask  
UVM, none of the grid fields  
DXUICE,DYUICE,DXTICE,DYTICE,CSUICE,CSTICE,TNGICE,TNGTICE are used  
anymore.
