NOAA National Centers for Environmental Information custodian carbon dioxide (CO2) gas analyzer carbon dioxide (CO2) gas analyzer measures gaseous carbon dioxide Carbon dioxide gas analyzer has often been referred to as LI-COR, because a lot of researchers choose to use products manufactured by LI-COR incorporation for their carbon dioxide measurement. The main component of a carbon dioxide analyzer is a nondispersive infrared (NDIR) spectroscopic sensors to detect CO2 in a gaseous environment by its characteristic absorption. Carbon dioxide (CO2) gas analyzer works together with carbon dioxide (CO2) equilibrator (insttypes_id 184) 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. 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.

Name : S. A. AGULHAS Flag : SOUTH AFRICA - ZA (ISO Country Code) Call Sign : ZSAF Platform Class : 31 Research vessel IMO : 7628136 Commissioned Date : 1978 Decommissioned Date : 2012-04 Current Length : 111.5 Built : 1978 Notes : Ice-strengthened vessel used for research and to service the South African Antarctic bases. Replaced by S. A. Agulhas II in 2012 and transferred to South African Maritime Safety Authority as a training ship. MMSI 601048000 Additional Information Sources: - http://en.wikipedia.org/wiki/S._A._Agulhas - http://new.marinetraffic.com/en/ais/details/ships/601048000 General Comments: Decommissioned flag has been set since platform class will change due to purpose change from research vessel to training vessel. From http://en.wikipedia.org/wiki/S._A._Agulhas : "In July 2012 the S. A. Agulhas was recommissioned as a training ship operated by the South African Maritime Safety Authority, the ship will continue to provide facilities for scientific research while training up to seventy merchant marine cadets."
