This dataset includes surface chemical, meteorological and physical data collected from Autonomous Surface Vehicle ASV_Saildrone1001 (EXPOCODE 32DB20170317) in the North Pacific Ocean, Coastal California region from 2017-03-17 to 2017-04-25. 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 from airblock, 2 feet above the sea surface at measured humidity; H2O Air - mole fraction of H2O in air from airblock, 2 feet above the sea surface; atmospheric pressure at the airblock, 2 feet above the sea surface; temperature of the Infrared Licor 820 in degrees Celsius; MAPCO2 %O2 - the percent oxygen of the surface seawater divided by the percent oxygen of the atmosphere at 2 feet above the sea surface; 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 at the airblock, 2 feet above the sea surface (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 at the airblock, 2 feet above the sea surface (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 at the airblock, 2 feet above the sea surface (100% humidity); dpCO2 - difference of the partial pressure of CO2 in seawater and air (pCO2 SW - pCO2 Air and pH of seawater (on total scale). The Autonomous Surface Vehicle CO2 (ASVCO2) instruments used to collect these data include Bubble type equilibrator for autonomous carbon dioxide (CO2) measurement, Carbon dioxide (CO2) gas analyzer, Humidity Sensor, and oxygen meter.
