  abstract = {{I}ron ({F}e) delivery by the {A}ntarctic {I}ce {S}heet ({AIS}) through ice shelf and iceberg melting enhances primary productivity in the largely iron-limited {S}outhern {O}cean ({SO}). {T}o explore this fertilization capacity, we implement a simple representation of the {AIS} iron source in the global ocean biogeochemical model {NEMO}-{PISCES}. {W}e evaluate the response of {F}e, surface chlorophyll, primary production, and carbon ({C}) export to the magnitude and hypothesized vertical distributions of the {AIS} {F}e fluxes. {S}urface {F}e and chlorophyll concentrations are increased up to 24% and 12 %, respectively, over the whole {SO}. {T}he {AIS} {F}e delivery is found to have a relatively modest impact on {SO} primary production and {C} export, which are increased by 0.063 +/- 0.036 {P}g{C} yr(-1) and 0.028 +/- 0.016, respectively. {H}owever, in highly fertilized areas, primary production and {C} export can be increased by up to 30% and 42 %, respectively. {I}cebergs are predicted to have a much larger impact on {F}e, surface chlorophyll, and primary productivity than ice shelves in the {SO}. {T}he response of surface {F}e and chlorophyll is maximum in the {A}tlantic sector, northeast of the tip of the {A}ntarctic {P}eninsula, and along the {E}ast {A}ntarctic coast. {T}he iceberg {F}e delivery below the mixed layer may, depending on its assumed vertical distribution, fuel a non-negligible subsurface reservoir of {F}e. {T}he {AIS} {F}e supply is effective all year round. {T}he seasonal variations of the iceberg {F}e fluxes have regional impacts that are small for annual mean primary productivity and {C} export at the scale of the {SO}.},
