  abstract = {{T}he predominant iron sources to the {S}outhern {O}cean ({SO}) are atmospheric deposition and sediment supply from the continental margin and their relative importance in governing {SO} carbon export remains a subject of great debate. {H}ere we report the results of simulations conducted with an ocean general circulation and biogeochemistry model ({OGCBM}) to quantify the importance of each source at different spatial scales at quasi-equilibrium. {O}verall, we find sediment derived iron is more important than dust derived iron in sustaining {SO} export production (by 1.4 to 9 times). {A}lthough dust iron is important in certain geographic sectors of the {SO}, this largely depends on the dust model employed. {A}pparent geographical correlations between dust deposition and export production can be misleading, since sediment iron can be transported to similar regions. {F}uture generation {OGCBM}s must better represent spatial variability in deposition fluxes and iron solubility from dust, as well as the poorly constrained, yet regionally important, sediment source. {C}itation: {T}agliabue, {A}., {L}. {B}opp, and {O}. {A}umont (2009), {E}valuating the importance of atmospheric and sedimentary iron sources to {S}outhern {O}cean biogeochemistry, {G}eophys. {R}es. {L}ett., 36, {L}13601, doi: 10.1029/2009{GL}038914.},
