| description | The overall goal of OUTPACE (Oligotrophy to
UlTra-oligotrophy PACific Experiment) was to obtain a successful
representation of the interactions between planktonic organisms and the
cycle of biogenic elements in the western tropical South Pacific Ocean
across trophic and N<sub>2</sub> fixation gradients. Within 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 South Pacific 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. The international OUTPACE cruise took place
between 18 February and 3 April 2015 aboard the RV <i>L'Atalante</i> and involved 60
scientists (30 onboard). The west–east transect covered ∼ 4000 km from the western part of the Melanesian archipelago (New Caledonia)
to the western boundary of the South Pacific gyre (French Polynesia).
Following an adaptive strategy, the transect initially designed along the
19° S parallel was adapted along-route to incorporate information
coming from satellite measurements of sea surface temperature, chlorophyll
<i>a</i>
concentration, currents, and diazotroph quantification. After 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. |
