These data include seawater temperature, salinity, dissolved oxygen, dissolved inorganic carbon (DIC), total alkalinity (TA), and macronutrients (Nitrate, Nitrite, Phosphate, Silicate, and Ammonium). The cruises were funded by the National Park Service to the University of Alaska Fairbanks College of Fisheries and Ocean Sciences. Marine carbonate parameters were analyzed by the Ocean Acidification Research Center. Observe the marine carbonate system to detect ocean acidification.

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.
