        abstract:  This dataset includes surface underway chemical and physical data collected during the R/V Bjarni Saemundsson cruise in the Irminger Sea, Iceland Sea and North Atlantic Ocean from 2010-02-08 to 2010-02-17. These data include measurements of sea surface temperature (SST), equilibrator temperature (TEQ), equilibrator pressure (PEQ), xCO2 in dry air at TEQ, pCO2 at TEQ (PCO2TEQ). The instruments used to collect these data include carbon dioxide (CO2) gas analyzer and shower head chamber equilibrator for autonomous CO2 measurement. These data were collected by Alice Benoit-Cattin-Breton and Solveig Rosa Olafsdottir of Marine and Freshwater Research Institute, Iceland.
        purpose:  To provide a high quality measurements of atmospheric and sea surface fCO2, temperature, and other parameters in the Irminger Sea, Iceland Sea and North Atlantic Ocean.

                code:  carbon dioxide (CO2) gas analyzer
            type:  carbon dioxide (CO2) gas analyzer
            description:  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.

            type:  showerhead equilibrator
            description:  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.
