The purpose was to monitoring of the IMR standard transects Svinøy, Gimsøy, Bjørnøya-Vest, and Fugløya-Bjørnøya. IMR takes biological (plankton), chemical (macronutrients, chlorophyll), and physical (CTD, ADCP) data at these sections several times every year. In addition, several Argo-floats were deployed. In order to get validation samples for the BGC-Argo floats staff from UiB and NORCE joined the cruise to collect and analyze carbonate chemistry (DIC, AT, pH), oxygen, and trace gas (CFC-12, SF6) data. This metadata describes these chemical data, as well as the macronutrients and salinity data. This dataset is available to the public for a wide variety of uses including scientific research and analysis.

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.
