This data package contains underway total alkalinity, water temperature, salinity and other variables collected from surface seawater during the R/V Atlantis Atlantic Zone Monitoring Program (AZMP2022) cruise (EXPOCODE 33AT20220319) in U.S. and Canadian East Coast waters and the Labrador Sea, North Atlantic Ocean from 2022-03-19 to 2022-05-16. Data were collected from the ship's underway seawater supply during a transit from Woods Hole MA to Greenland. This effort was part of the jointly-funded NOAA-DFO grant entitled "Improving Regional Northwest Atlantic Observations Through Enhanced Collaboration". Along with total alkalinity, corresponding temperature and salinity measurements are included.

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; 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 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 CRM. For more details regarding instrument deployment and performance, see Hunt et al. (2021, Marine Chemistry 232, 103960). CRM Batch 198 was used during this cruise.; CRM manufacturer: Dr. Andrew Dickson, Scripps Institute of Oceanography; CRM batch number: 198; Preservation method: none; Preservative volume: none; Preservative correction: none; Uncertainty: 2.3±13; Method reference: Aßmann, S., Frank, C., Petersen, W., Körtzinger, A., 2013.
