Specifically, this dataset includes discrete bottle measurements of dissolved inorganic carbon, total alkalinity, and salinity, as well as corresponding CTD measurements of temperature, salinity, and dissolved oxygen. Observations were made throughout the eastern Canadian Arctic including in Baffin Bay, Nares Strait, some passages of the Canadian Arctic Archipelago, and various fjord systems in all of these sub-regions. These measurements were collected during Leg 2 (KEBABB program) and Leg 3 (ArcticCORE program) of the 2023 Amundsen expedition. 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.
