    • Dissolved inorganic carbon, total alkalinity, pH, nutrients and other variables collected from discrete profile observations using CTD, Niskin bottle, and other instruments in the East Coast of the U.S. and Canada during the 2nd East Coast Ocean Acidification (ECOA2, or ECOA-2) cruise from 2018-06-25 to 2018-07-29 (NCEI Accession 0196419)

    Metadata Updated: August 1, 2025

    This dataset contains the discrete bottle data from the second East Coast Ocean Acidification (ECOA2 or ECOA-2). The ECOA2 Cruise on board NOAA Ship Henry B. Bigelow from Newport, took place in the Gulf of Maine and then along the East US coast to Miami. 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 14 transects approximately orthogonal to the Gulf of Maine and Atlantic coasts and a comprehensive set of underway measurements along the entire transect.
