[MITgcm-support] seaice

Mike, Dimitris,

I am pretty sure that the periodic boundary conditions are not a 
problem in general, because I have 1000y integrations with the 
global_ocean.90x40x15 experiment plus seaice that are stable. I 
suspect there is a problem in trying to run the (seaice) model on a 
cartesian grid. I don't think it can do that, yet. Can it?
Try using spherical coordinates instead (even though it doesn't 
make much sense in a channel).

Mike what blows up, the ocean model or the sea-ice model,
and what are symptoms of blow-up, i.e., what happens
during few time steps preceding the blow-up?
