Brown 3nd East Coast Ocean Acidification (ECOA3, or ECOA-3) cruise (EXPOCODE 33RO20220806) from 2022-08-06 to 2022-09-23 (NCEI Accession 0283329)",
    "description": "The East Coast Ocean Acidification (ECOA-3) Cruise on board the R\/V Ronald H. Brown 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 24 transects approximately orthogonal to the Gulf of Maine and Atlantic coasts and a comprehensive set of underway measurements along the entire transect.",
