Processing Steps
  • Parameter or Variable: Total alkalinity; Abbreviation: TA; Unit: micromoles per kilogram; Observation type: surface underway; Measured or calculated: measured; Sampling instrument: CONTROS HydroFIA® TA; Analyzing instrument: CONTROS HydroFIA® TA; Type of titration: single acid addition; Cell type (open or closed): closed (with CO2 removal via chemical absorption); Detailed sampling and analyzing information: An inline filter (0.2 µm) with small 50 mL overflow reservoir for filtered seawater was supplied with the ship's underway seawater supply. 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 calibrated using certified reference material (CRM) obtained from Dr. Andrew Dickson at Scripps Institution of Oceanography. The instrument was calibrated before each cruise, and periodic CRM measurements were made during each cruise. These CRM measurements were used to correct the underway sample data. For more details, see Hunt et al. (2020, in review). CRM Batch 163 was used during these cruises.; CRM manufacturer: Dr. Andrew Dickson, Scripps Institute of Oceanography; Preservation method: none; Preservative volume: none; Preservative correction: none; Uncertainty: 2.3±13; Method reference: Aßmann, S., Frank, C., Petersen, W., Körtzinger, A., 2013. 2013.
