Brown cruise RB2104 (EXPOCODE 33RO20210315) in the Caribbean Sea, North Pacific Ocean, U.S. West Coast from 2021-03-17 to 2021-03-30. Data were collected from the ship's underway seawater supply during a transit from Key West FL to San Diego CA. This effort was part of the NOAA Ocean Acidification Program (OAP) grant entitled "Expanding near-shore carbonate measurements along the East-coast and Gulf of Mexico through multiple collaborations". Along with total alkalinity, corresponding temperature and salinity measurements are included. Measurements of pCO2 taken on these cruises are available from NOAA's AOML. This dataset is available to the public for a wide variety of uses including scientific research and analysis.

The HydroFIA TA then drew the sample from the reservoir into the instrument for analysis. The HydroFIA TA instrument performed a single-point titration of seawater with 0.1N hydrochloric acid (HCl), using bromocresol green (BCG) as the indicator for spectrophotometric pH detection.; Replicate information: 2.0 µmol/kg, calculated as one standard deviation of triplicate measurements of certified reference material; Standardization description: The instrument was initially calibrated before departure using certified reference material (CRM) obtained from Dr. Andrew Dickson at Scripps Institution of Oceanography. Instrument stability was then checked periodically during the cruise using filtered, bagged Gulf Stream seawater. For more details regarding instrument deployment and performance, see Hunt et al. (2021, Marine Chemistry 232, 103960).
