Graph showing ecoGEnIE simulation results for global POC export flux under different configurations and forcing scenarios. Results for RCP4.5 and RCP8.5 are shown for each of the configurations (BIO+FPR, BIO+TDR, ECO+FPR, ECO+TDR), and the baseline POC export and the 21st century are marked by the horizontal and vertical dotted lines respectively. Under default BIO+FPR settings global POC export falls by ~7% by 2500 under RCP4.5 (~20% under RCP8.5); BIO+TDR instead leads to ~5% increase in POC export by 2500 under RCP4.5 (~22% under RCP8.5); ECO+FPR leads to ~9% less export by 2500 under RCP4.5 (~25% under RCP8.5); and ECO+TDR leads to ~3% less POC export by 2500 under RCP4.5 (and ~2% more under RCP8.5).
