Seawater temperature is measured at the intake of the UW system (ship’s bow) using a SBE38 inline temperature sensor. Temperature is also measure before the equilibrator using a SBE21 thermosalinograph and at the equilibrator using a Fluke 45 multimeter and a Pt100 temperature probe. Information of calibration for all sensors is presented below. The system is using a Licor LI7000 NDIR analyser. The sample is partially dried using a Nafion column (Perma Pure MD- 070-48S-4). The seawater flow rate is approx. 2 lpm and and the gas flow rate to the NDIR is approx. 1.8 nlpm.

NOAA National Centers for Environmental Information custodian showerhead equilibrator showerhead equilibrator extracts dissolved CO2 from water A carbon dioxide equilibrator is usually in the shape of a vertical tube, with a showerhead on the top, some headspace, a lot of beads to increase the surface exchange area between water and air, a water seal device at the bottom to allow water to overflow, but prevents air exchange between inside and outside. Carbon dioxide (CO2) equilibrator works together with carbon dioxide (CO2) gas analyzer (insttypes_id 183) to measure carbon dioxide in the water. To measure water carbon dioxide, water needs to be continuously supplied to a showerhead inside an equilibrator. As the water flows through the equilibrator chamber, dissolved carbon dioxide exchanges quickly with air in the headspace. This air is then sampled by the carbon dioxide analyzer to determine the mole fraction of CO2 in water. RV Simon Stevin ICES request for the vessel Simon Stevin from BELGIUM.
