Discrete profile measurements of dissolved inorganic carbon (DIC), total alkalinity (TALK), temperature, salinity and other parameters during the R/V L'Atalante "Oligotrophy from Ultra-oligoTrophy PACific Experiment" (OUTPACE) cruise (EXPOCODE 35A320150218) in the South Pacific Ocean from 2015-02-18 to 2015-04-03 (NCEI Accession 0177706)

This dataset consists of discrete profile measurements of dissolved inorganic carbon (DIC), total alkalinity (TALK), temperature, salinity, oxygen and nutrients during the R/V L'Atalante Oligotrophy from Ultra-oligoTrophy PACific Experiment (OUTPACE) cruise (EXPOCODE 35A320150218) in the South Pacific Ocean from 2015-02-18 to 2015-04-03. The main focus of the OUTPACE cruise was to study the complex interactions between planktonic organisms and the cycle of biogenic elements on different scales, motivated by the fact that the WTSP has been identified as a hot spot of N2 fixation (Bonnet et al., 2017). The data presented here have been collected in the western tropical South Pacific along a longitudinal 4000 km transect between the Melanesian Archipelago and the western part of the South Pacific gyre mostly between the surface and 2000 m depth. The OUTPACE transect is close to existing WOCE and GO-SHIP lines in the South Pacific: it is parallel to the zonal P21 line (18S) and the P06 line (32S).
