  1. Morten D. Skogen morten@imr.no NORWECOM in ROMS

  2. The NORWECOM model system Norwegian/Barents Sea examples Future works… Outline of talk

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

  4. 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 NORWECOM (2)

  5. Primary production Respiration Algae death Regeneration Self shading Turbidity Sedimentation Resuspension Denitrification Diatoms, flagellates (chatonella) Detritus and diatom skeletals Inorganic nitrogen, phosphorus, silicate Oxygen Light model NORWECOM (3)

  6. The biological model

  7. Physics from ROMS v2.0 including ice (W.P.Budgell, IMR) 50km resolution in Nordic and Barents Seas Forced by NCEP daily mean fluxes Biology in offline mode Examples from 1999 NORWECOM (4)
