  • 4 4 NORWECOM (2) first coupled physical-chemical-biological model for the whole North Sea physics based on POM (until now.?) runs operational (7 days forecast) at met.no http://moncoze.met.no environmental status, eutrophication issues, what- if scenarios, climate/fish relations,.. North Sea, Skagerrak/Kattegat, Norwegian fjords, Benguela, Mozambique Channel
