    • Surface underway, profile measurements of water temperature, salinity, dissolved oxygen concentration, dissolved inorganic carbon (DIC), total alkalinity (TA), pH, delta C13 and other hydrographic and chemical parameters obtained during the East Coast Ocean Acidification (ECOA-3) Cruise on board the NOAA Ship Ronald H. Brown in the East Coast US, North Atlantic Ocean from 2022-08-06 to 2022-09-23 (NCEI Accession 0295751)

    Metadata Updated: November 1, 2025

    This dataset consists of surface underway, profile measurements of water temperature, salinity, dissolved oxygen concentration, dissolved inorganic carbon (DIC), total alkalinity (TA), pH, delta C13 and other hydrographic and chemical parameters obtained during the East Coast Ocean Acidification (ECOA-3) Cruise on board the NOAA Ship Ronald H. Brown in the East Coast US, North Atlantic Ocean from 2022-08-06 to 2022-09-23. The effort was in support of the coastal monitoring and research objectives of the NOAA Ocean Acidification Program (OAP). The cruise was designed to obtain a snapshot of key carbon, physical, and biogeochemical parameters as they relate to ocean acidification (OA) in the coastal realm. The cruise included a series of 24 transects approximately orthogonal to the Gulf of Maine and Atlantic coasts and a comprehensive set of underway measurements along the entire transect.
