Surface samples were collected at 3-5 m depth, from within the surface mixed layer.We transferred seawater from each Niskin bottle into a single 250 mL borosilicate glass bottle for analysis of both DIC and TAlk. 1 mL of seawater was removed from each sample bottle to allow for thermal expansion, and then 100 uL of saturated mercuric chloride solution was added to halt biological activity. The bottles were then sealed using Apiezon® L greased ground-glass stoppers. Samples were stored at 4 °C in the dark until they were analyzed after the cruise. Briefly, for DIC analysis, samples were analyzed at room temperatures. Each seawater sample (0.5 mL) was acidified using phosphoric acid and the evolved CO2 gas was extracted and carried by pure N2 gas to an infrared CO2 detector (Li-Cor 6262) for quantification. For each DIC sample, sub-samples were sequentially analyzed 2 or 3 times until we obtained two replicates with a precision within 0.1%. The average of the two values is reported. The precision of the DIC measurements was +/- 2 umol/kg. The accuracies of the DIC measurements were determined by routine analysis of certified reference material (CRM) provided by A. G.

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.
