difference between the ensemble results (unweighted) for the current state (CS) and the pre-eutrophic state (historic scenario, HS) for the N:P ratio 
‘'A), net primary production (B) and near bed oxygen levels (C). Green colours indicate areas where the pre-eutrophic levels were lower than those 
3f the current state. Note the changing colour bar scale, for O» the scale starts at 1%.

Model results of winter total phosphorus concentration (Ptot) as a function of winter total nitrogen concentration (Ntot) in each area for each 
model. (A) current conditions, (B) pre-eutrophic conditions (both 2009-2014). The colours indicate the modelled net primary production (NPP) for 
:he corresponding areas and models. The line indicates the global ocean Redfield ratio (N:P = 16). Only some outlying results have been named, for 
area acronyms see Appendix C.
