NORWECOMThe NORWegian ECOlogical Model system
http://www.imr.no/~morten/norwecom
A coupled physical-chemical-biological model system appliedto study primary production and dispersion of particles
(e.g. fish larvae and/or pollution)
Main partners:
Institute of Marine ResearchDept. of Fisheries and Marine Biology, Univ. of Bergen
Dept. of Mathematics, Univ of BergenThe Norwegian Meteorological institute

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
