| Definition | A shipborne underway pCO2 system with continuous real-time data feeds, commissioned in 2004 and developed by Plymouth Marine Laboratory (PML) and Dartcom for permanent installation on UK research vessels. The system was designed to determine the partial pressure of CO2 (pCO2) in seawater. The operating principle of the PML-Dartcom Live pCO2 system involves equilibrating the pCO2 in air with that of seawater. The CO2 concentration of the equilibrated air is then measured using a non-dispersive infrared analyser, which is calibrated with gases of known CO2 concentration. [CHAP 4, SOP 5 of Dickson, A.G., Sabine, C.L. and Christian, J.R. (Eds.) 2007. Guide to best practices for ocean CO2 measurements. PICES Special Publication 3, 191 pp.] The system comprises a vented-showerhead equilibrator, a Peltier cooler for partial drying of the equilibrated gas stream, CO2/H2O gas analyser LI-COR LI-840, and associated mechanical and electronic hardware. The system can reach a precision of +/- 4 uatm. | ||
