These data include air-sea difference - partial pressure of carbon dioxide (pCO2), barometric pressure, oxygen, pCO2 - atmosphere, pCO2 - water, salinity, sea surface temperature, oxygen, pH on total scale, total chlorophyll, nephelometric turbidity unit and salinity-compensated dissolved oxygen. The Moored Autonomous pCO2 [MAPCO2 (trademark of NOAA)] 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. The Global CO2 Time-series and Moorings Project involves international groups from 18 countries who have mounted sensors on moored buoys to provide high resolution time-series measurements of atmospheric boundary layer and surface ocean CO2 partial pressure (pCO2). The CO2 Time-series and Moorings Project is coordinated by UNESCO International Ocean Carbon Coordination Project (IOCCP).";
