Abstract
The CO2 data onboard Statsraad Lehmkuhl are measured with a General Oceanics pCO2 system (GO 8050). This dataset consists of the raw data from the instrument. The system consists of an equilibrator, through which seawater is pumped with a flow of about 3L/min. A spiral nozzle forms a regular spray, so that the water and the gas phase achieve equilibrium fast. The gas phase is then pumped through a NDIR analyzer (Licor, LI 7000), which measures mole fraction of carbon dioxide. The system is equipped with one zero and 3 non-zero reference gases. Intake temperature is measured with a Fluke 1521. Equilibrator pressure is measured with an absolute pressure sensor (GE Druck 81). This installation was financed by the Geophysical Institute/University of Bergen and ICOS.
