[MITgcm-support] seaice

[Jinlun Zhang]

As Martin mentioned, the sea ice model should work on periodic b.c. Right 
now, the model is written on spherical coords. But it should work on a 
cartesian grid if one can find the grid link between spherical and 
cartesain.

Mike, have you tried the following 4 cases:
(1) ocean only + closed bc
(2) ocean only + open bc
(3) ice + ocean + close bc
(4) ice + ocean + open bc
