Discrete dissolved inorganic carbon (DIC), total alkalinity (TA), salinity, and nutrient samples were taken from rosette casts with 10L Niskin bottles and analyzed at the Institute of Ocean Sciences. Discrete samples of dissolved oxygen were also collected and analyzed onboard the vessel. CTD profiles were recorded with each rosette cast. DIC/TA samples were placed in cool storage after collection and returned to the shore-based lab for analysis. Oxygen units were converted to µmol/kg when reported in ml/L. Nutrient concentrations were converted to µmol/kg from µmol/L. The raw data and other supporting documents can be obtained from https://www.waterproperties.ca/.

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.
