??? Please note that the pCO2 Monitoring System OceanPack SAE can only be operated upon request. Request operations with the pCO2 Monitoring System OceanPack SAE to AWI-Logistics in sufficient time prior to the cruise. ???: The system runs continuously during all cruises. Support is given by the board electricians. Plaease ask them if you need specific info, or contact the responsible AWI scientist. |

???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. |
