[MITgcm-support] sea ice for global_oce_biogeo_bling

[Isa Rosso]

Hi Manfredi,

thanks for your reply and suggestions! I’ll keep in mind to use the LLC90 set-up in case I find other issues.. For the moment, the model seems working fine with sea ice free-drift on instead of the dynamics, so I think I’ll see how it goes with that. 

cheers,
isa
