[MITgcm-support] obcs problem

[Dimitris Menemenlis]

Chuncheng, you can look at
http://ecco2.jpl.nasa.gov/data1/arctic/run_template_cube81/mk_run_template.m
for an example of balancing boundary conditions offline.  Search for  
"balance BCs".
When I do that, I find that mean sea level remains balanced.  Dimitris
