Summary
The OceanPack Sea-Air-Exchange system measures the partial pressure of CO2 (pCO2) in seawater using membrane equilibration and Li-cor IR analyser for CO2 detection. The instrument reports mole fraction of CO2 in wet air in ppm. Values of pCO2 in microatm can only be obtained with shore-based data processing.
