  abstract = {{T}he hydrological and geochemical properties of the waters constituting the {P}acific {E}quatorial {U}ndercurrent ({EUC}) determine the properties of the equatorial cold tongue. {U}nderstanding and quantifying the various {EUC} origins is therefore of prime importance. {F}or this purpose, a high-resolution (1/4 degrees) interannual oceanic simulation was analyzed from the western tropical {P}acific boundaries to 140 degrees {W}, using a {L}agrangian framework. {W}aters from the {L}ow-{L}atitude {W}estern {B}oundary {C}urrents ({LLWBC}s) transiting from {V}itiaz {S}trait (the main contributor), from {S}olomon {S}trait, and via the {M}indanao {C}urrent were identified as the principal sources to the {EUC}. {W}aters conveyed by the interior ocean off equator are negligible till 180 {E}. {T}he {LLWBC}s' waters represent 87% of the {EUC} transport at 156 degrees {E} out of which the {N}ew {G}uinea {C}oastal {U}ndercurrent ({NGCU}) is as large as 47%. {T}he {EUC} meridional distribution suggests that the waters originating from {S}olomon {S}trait and {M}indanao {C}urrent mostly remain in the hemisphere from which they originate. {C}ontrastingly, {V}itiaz {S}trait waters are found in both hemispheres. {T}he vertical {EUC} distribution shows that the lower layer of the {EUC} is mainly composed of {V}itiaz {S}trait waters. {F}inally, the source transport distributions were characterized, at their origin and within the {EUC}, as a function of density. {T}hese distributions showed that waters flowing through {V}itiaz {S}trait at densities higher than those of the {EUC} (down to sigma(theta) = 27.2 kg m(-3)) undergo a diapycnal mixing and lighten during their journey to join the {EUC}. {T}his lightening supports the suggestion that the {NGCU} is a major source for the {EUC} geochemical enrichment.},
