    • Underway total alkalinity, water temperature, salinity and other variables collected from surface seawater during the NOAA Ship Ronald H. Brown 2021 West Coast Ocean Acidification cruise RBWCOA2021 (EXPOCODE 33RO20210613) in the North Pacific Ocean from 2021-06-14 to 2021-07-20 (NCEI Accession 0288994)

    Metadata Updated: December 1, 2025

    This data package contains Underway total alkalinity, water temperature, salinity and other variables collected from surface seawater during the NOAA Ship Ronald H. Brown 2021 West Coast Ocean Acidification cruise RBWCOA2021 (EXPOCODE 33RO20210613) in the North Pacific Ocean from 2021-06-14 to 2021-07-20. Data were collected from the ship's underway seawater supply during the NOAA Ocean Acidification Program-funded West Coast Ocean Acidification (WCOA) cruise. This underway TA 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.
