  abstract = {{T}he overall goal of {OUTPACE} ({O}ligotrophy to {U}l{T}ra-oligotrophy {PAC}ific {E}xperiment) was to obtain a successful representation of the interactions between planktonic organisms and the cycle of biogenic elements in the western tropical {S}outh {P}acific {O}cean across trophic and {N}-2 fixation gradients. {W}ithin the context of climate change, it is necessary to better quantify the ability of the oligotrophic ocean to sequester carbon through biological processes. {OUTPACE} was organized around three main objectives, which were (1) to perform a zonal characterization of the biogeochemistry and biological diversity of the western tropical {S}outh {P}acific during austral summer conditions, (2) to study the production and fate of organic matter (including carbon export) in three contrasting trophic regimes (increasing oligotrophy) with a particular emphasis on the role of dinitrogen fixation, and (3) to obtain a representation of the main biogeochemical fluxes and dynamics of the planktonic trophic network. {T}he international {OUTPACE} cruise took place between 18 {F}ebruary and 3 {A}pril 2015 aboard the {RV} {L}'{A}talante and involved 60 scientists (30 onboard). {T}he west-east transect covered similar to 4000 km from the western part of the {M}elanesian archipelago ({N}ew {C}aledonia) to the western boundary of the {S}outh {P}acific gyre ({F}rench {P}olynesia). {F}ollowing an adaptive strategy, the transect initially designed along the 19 degrees {S} parallel was adapted along-route to incorporate information coming from satellite measurements of sea surface temperature, chlorophyll a concentration, currents, and diazotroph quantification. {A}fter providing a general context and describing previous work done in this area, this introductory paper elucidates the objectives of {OUTPACE}, the implementation plan of the cruise and water mass and climatological characteristics and concludes with a general overview of the other papers that will be published in this special issue.},
