Instrument: NIWA Underway pCO2 system
This partial pressure of carbon dioxide (pCO2) analysis system sampled from the vessel R/V Tangaroa's underway system. The pCO2 was measured by infrared analysis of the carbon dioxide of air continuously equilibrated with pumped seawater. The pCO2 rig was located on a bench in the temperature controlled laboratory off the fish factory, beside the pH systems (continuous and discrete) and the alkalinity system.additional details are available in the SAGE pCO2 Data Report
