  abstract = {{A}s part of the {PANDORA} cruise ({GEOTRACES} {GP}12), concentrations of dissolved iron (d{F}e) were measured at 11 stations inside and outside the {S}olomon {S}ea, a semi-enclosed sea in the western tropical {P}acific, with complex topography and straits, and strong western boundary currents supplying the equatorial current system. {T}hese measurements aimed to better assess the various sources of d{F}e in our study area and the {S}olomon {S}ea's potential as a source of d{F}e for the {E}quatorial {U}ndercurrent ({EUC}). {A} simple box model allows calculating and discussing the fate of the d{F}e in the different water layers flowing through the {S}olomon {S}ea and suggests that the amount of d{F}e enrichment within the enclosed sea was not significant for the lower thermocline and intermediate waters, indicating that most of the d{F}e was acquired prior to reaching the {S}olomon {S}ea at the entrance and/or that inputs are approximately balanced by scavenging within the basin for these two layers. {I}n contrast, d{F}e enrichment was significant for the upper thermocline layer and the deep waters, highlighting enrichments from external sources, as well as combination of internal processes, such as scavenging and/or organic complexation. {T}he relative d{F}e contribution of the {S}olomon {S}ea to {EUC} was 20 %, on average. {O}ther sources might thus provide d{F}e to the {EUC}, along the water transport downstream of the {S}olomon {S}ea (e.g. {B}ismarck {S}ea) or from the northern hemisphere. {D}iazotrophs such as {T}richodesmium might also contribute to the d{F}e enrichment of the {EUC} after export and remineralization at depth outside the {S}olomon {S}ea.},
