[MITgcm-support] Open boundary conditions!

[Nicolas Grisouard]

Hi,

The default setting for the boundaries is periodic. So if you turn  
OBCs off, you will get at one boundary the same value as at the  
opposite boundary, not zero.

I don't know about the freezing temperatures, sorry.

Cheers,
Nicolas
