a–f, Time series of main biogeochemical fluxes and respective ratios expressed in terms of nitrogen and carbon over the AO during the historical (1970–2014) and forecast (2015–2100) periods: integrated remineralization rate (TgN yr−1) (a), remineralization efficiency (=remineralization in the upper 100 m/export flux) (b), nitrogen (c) and carbon (e) export fluxes at 100 m (TgN yr−1, TgC yr−1), and respective nitrogen (d) and carbon (f) export efficiencies illustrating the ‘BCP efficiency’ (=export flux/net nitrogen assimilation by phytoplankton; export flux/NPP). Bars on the right represent the contributions of climate change (purple), terrigenous inputs (orange) and the scenario uncertainty (black).
