Processing Steps	Parameter or Variable: SST; Abbreviation: SST; Unit: DEG_C; Controlled vocabulary name: SEA SURFACE TEMPERATURE; Observation type: Temperature from the ship's thermosalinograph (°C); In-situ / Manipulation / Response variable: in-situ; Analyzing instrument: SeaBird model SBE-21; Detailed sampling and analyzing information: Seawater samples are taken daily at the thermosalinograph outlet. Samples are analysed at SHOM-France in an OSIL Portasal, and compared to IAPSO Sea Water Standards. The thermosalinograph is calibrated every 18 months, either at Seabird-USA or at SHOM-France. The seawater inlet of both CO2 analyser and TSG is located on the sea chest. The TSG is very close to the hull, the sea water flow rate is 30 l/min. We consider that the temperature inside the TSG is the SST. The warming between the TSG and the CO2 analyser is 0.2°C (Tequ - TTSG).; Uncertainty: resolution: 0.001°C ; Temperature accuracy: ± 0.01°C.

Parameter or Variable: ATM_PRE; Abbreviation: ATM_PRE; Unit: Atm; Controlled vocabulary name: BAROMETRIC PRESSURE; In-situ / Manipulation / Response variable: in-situ; Analyzing instrument: Druck barometer RPT350; Detailed sampling and analyzing information: The barometric pressure was measured in the bridge, ~20 m above the equilibrator. The Druck barometer is placed in a box, which also contains the GPS and the Iridium transmitter. It was calibrated in March 2015.; Uncertainty: Accuracy: ± 0.01 %.

Parameter or Variable: Mole fraction of CO2 (dry) in air or equilibrated air (ppm); Abbreviation: xCO2; Unit: PPM, Mole fraction of CO2 (dry) in air or equilibrated air; Controlled vocabulary name: Partial pressure (or fugacity) of carbon dioxide - water; Observation type: Measured; In-situ / Manipulation / Response variable: in-situ; Analyzing instrument: LI-COR model 6262; Detailed sampling and analyzing information: The general principle of instrumental design can be found in Pierrot et al. (2009). The concentration of CO2 in the headspace gas was measured using the adsorption of infrared (IR) radiation by the CO2 molecule. The LI-COR analyzer passed IR radiation through two cells. The reference cell is constantly flushed with a reference gas CO2-free. The sample cell is flushed with the gas of interest (standard, outside atmosphere, or headspace gas from equilibration chamber). The infrared analyzer is calibrated regularly using three standard gases (250-500 ppm) from Air Liquide - France, which were calibrated at DT INSU against primary NOAA standards for the high standard and at LSCE for the other two (ICOS Atmospheric Thematic Center). The exact concentrations of the standards are: 0 ppm (nitrogen gas) 249.81 ± 0.01 ppm 357.32 ± 0.01 ppm 503.75 ± 0.49 ppm; Uncertainty: CO2 resolution: 0.01 µmol/mol; CO2 accuracy: ± 1 ppm at 350 ppm. Parameter or Variable: Water content of Licor in mmol/mol; Abbreviation: H2Omm; Unit: MMOL/MOL; In-situ / Manipulation / Response variable: in-situ. Parameter or Variable: Equilibrator Pressure; Abbreviation: Pequ; Unit: hPa; In-situ / Manipulation / Response variable: in-situ; Analyzing instrument: Setra model 239, differential pressure; Detailed sampling and analyzing information: The pressure in the equilibrator relative to the bow thruster compartment was measured with a Setra model 239 differential barometer. The LI-COR barometer measured the barometric pressure of the compartment. The absolute pressure of the equilibrator headspace reported in data files is the sum of the infrared analyzer pressure and the differential pressure from the pressure transducer attached to the equilibrator.; Uncertainty: Resolution: 0.01 hPa; Accuracy: ± 0.052 hPa. Parameter or Variable: Fugacity in CO2 in seawater (µatm); Abbreviation: fCO2sw; Unit: UATM; Controlled vocabulary name: partial pressure of carbon dioxide - water; In-situ / Manipulation / Response variable: in-situ .
