These data were collected as part of the Hakai Institute’s objective to report on patterns of ocean acidification in coastal British Columbia. Temperature, salinity, and pressure data were also captured using CTD profilers (either Sea-Bird Electronics or RBR units following best practices) at the time of seawater collection, and profile data was extracted for the depth at which Niskin bottles were tripped. Sampling depth was determined by calibrated line meter on the research vessel or RBR Solo pressure sensors attached to the Niskin bottle. Samples were fixed at the time of collection using 80 µl of mercuric chloride aboard the Hakai Institute’s research vessel. Temperature and salinity were determined at the time of sample analysis at the Quadra Island Field Station (QIFS) using NIST traceable thermometers (VWR PN 23609-176) and a YSI MultiLab 4010-1 with a MultiLab IDS 4310 conductivity and temperature probe. The YSI probe was calibrated using certified reference materials of known salinity prior to seawater sample analysis. For detailed protocols on sample collection and data processing, including CO2 system determination, please see Campbell et al. (2023; https://doi.org/10.21966/1.521066). 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.
