The two VOS have a SBE38 Digital Oceanographic Thermometer (SeaBirdTM), located at the seawater inlet, measuring the sea surface temperature (SST) with high accuracy (± 0.001ºC).The seawater then splits into three lines; the first goes to a set of additional sensors, including an SBE45 Digital Thermosalinograph (accuracy of ± 0.001ºC and ± 0.0001 S m-2 for temperature and conductivity, respectively) for sea surface salinity (SSS), and an Aanderaa sensor for oxygen.The second seawater line goes to the equilibrator system, located in the wet box of a General OceanicsTM GO8050 automated seawater system and then to the non-dispersive infrared LICOR© analyser for gas detection (models 6262 until 2021 and 7000 later) placed inside the dry box responsible for measuring the molar fraction of CO2 (xCO2, ppm).The analyser is automatically calibrated on departure and arrival at each port and periodically in a loop every three hours using four standard gases (in the order of 0 ppm, 250 ppm, 400 ppm and 550 ppm and with an accuracy of ±0.02 ppm).They are provided by the National Ocean and Atmospheric Administration (NOAA) and the ICOS CAL research facilities (after 2022) BechinjiguaExpress
