  abstract = {{L}arge uncertainties in projected future changes of {I}ndian {O}cean chlorophyll across {E}arth {S}ystem {M}odels are largely attributed to differences in biogeochemical process representation. {W}e show, however, that large biases in the historical physical state of the ocean and inter-model differences in future climate also play a substantial role. {U}sing a bias-corrected ocean-only model forced by air-sea flux anomalies from multiple {CMIP}6 models, we find that correcting historical physical state biases amplify projected summer surface chlorophyll ({SC}hl) changes by up to a factor of two and improves inter-model consistency. {H}eat flux driven enhanced upper ocean stratification, consistently reduces {SC}hl by -10% to -40%, depending on the upwelling region. {W}ind-driven nutricline changes dominate responses in {SC}hl, off southern {I}ndia (-45% wind effect versus -30% from stratification) and {S}umatra (+25% versus -12%). {T}hese results highlight the need to improve the representation of monsoonal winds and their future evolution to better constrain biogeochemical projections.},
