  • Modifications liées au calcul des nouveau sous-fractions
  • Nettoyage de ocean slab : il reste uniquement la version avec glace de mer forcé
  • Nouveaux variables pour distiguer la version et type d'ocean : type_ocean=force/slab/couple, version_ocean=opa8/nemo pour couplé ou version_ocean=sicOBS pour slab

62! surface is done and finally it sends some fields to the coupler.
