CTD-O2 (Conducticity-Temperature-Depth-Oxygen) data were collected with a SEA-BIRD SBE911+ (SBE19 for FR6-8) CTD in the Gulf of Guinea during cruises carried out from 1997 to 2017 in the framework of the programs «Prediction and Research morred Array in the Tropical Atlantic» (PIRATA ; Bourlès et al., 2008).
CTD-O2 (Conducticity-Temperature-Depth-Oxygen) data were collected with a seabird SBE911+ (SBE19 for FR6-8) CTD. The vertical profiling resolution was nominally 1db (=bin size). FR-1-to-17 data were only processed with SBEDataProcessing. FR18-to-22 CTD data were processed and controlled using chemical analysis made on discrete samples. The last CTD data (FR23-to-27) were processed using an improved version of CADHYAC software (Kermabon et al., 2015) carried out by the US IMAGO (IRD). For details on the data processing methodology, see reports. Absolute referencing was provided by Global Positioning System (GPS) navigation.
