contenttypeSummary

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.

Components

The system consists of a flow-through unit for CO2 extraction at a membrane and CO2 detection by a Li-cor Infra Red (IR) analyser. The instrument reports "mole fraction of CO2 in wet air [ppm]". Values of "pCO2 [µatm] can only be obtained with shore-based data processing.
