This dataset includes surface chemical, meteorological and physical data collected from Autonomous Surface Vehicle ASV_Saildrone1020 (EXPOCODE 32DB20190119) in the South Atlantic Ocean, South Pacific Ocean, Indian Ocean and Southern Ocean from 2019-01-19 to 2019-08-03. These data include xCO2 SW (wet) - mole fraction of CO2 in air in equilibrium with the seawater at sea surface temperature and measured humidity; H2O SW - mole fraction of H2O in air from equilibrator; xCO2 Air (wet) - mole fraction of CO2 in air at measured humidity; H2O Air - mole fraction of H2O in air; barometric pressure; MAPCO2 %O2 - the percent oxygen of the surface seawater divided by the percent oxygen of the atmosphere; SST - sea surface temperature; SSS - sea surface salinity; xCO2 SW (dry) - mole fraction of CO2 in air in equilibrium with the seawater at sea surface temperature (dry air); xCO2 Air (dry) - mole fraction of CO2 in air (dry air); fCO2 SW (sat) - fugacity of CO2 in air in equilibrium with the seawater at sea surface temperature (100% humidity); fCO2 Air (sat) - fugacity of CO2 in air (100% humidity); dfCO2 - difference of the fugacity of the CO2 in seawater and the fugacity of the CO2 in air (fCO2 SW - fCO2 Air); pCO2 SW (wet) - partial pressure of CO2 in air in equilibrium with the seawater at sea surface temperature (100% humidity); pCO2 Air (wet) - partial pressure of CO2 in air (100% humidity); dpCO2 - difference of the partial pressure of CO2 in seawater and air (pCO2 SW - pCO2 Air) and Wind speed at the anemometer.
