    • Surface underway and surface discrete measurements of dissolved inorganic carbon (DIC), total alkalinity (TA), water temperature, salinity, partial pressure of CO2 (pCO2), pH, on total scale nutrients and other parameters obtained onboard the NOAA ship Ronald H. Brown during the GOMECC-4 cruise in the Gulf of Mexico and North Atlantic Ocean from 2021-09-13 to 2021-10-21 (NCEI Accession 0286818)

    Metadata Updated: December 1, 2025

    This dataset contains the surface underway and surface discrete measurements of dissolved inorganic carbon (DIC), total alkalinity (TA), water temperature, salinity, partial pressure of CO2 (pCO2), pH, on total scale nutrients and other parameters obtained onboard the NOAA ship Ronald H. Brown during the GOMECC-4 cruise in the Gulf of Mexico and North Atlantic Ocean from 2021-09-13 to 2021-10-21. The ship departed from Key West, FL into the Gulf of Mexico and then around the coastal waters of the Gulf of Mexico in a counter-clockwise direction. The cruise ended in St. Petersburg, FL. The effort was in support of the coastal monitoring and research objectives of NOAA’S Ocean Acidification Program. 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. This was the fourth occupation of the Gulf of Mexico as part of the Ocean Acidification Program’s monitoring efforts, with the first three occurring in 2007, 2012 and 2017. The cruise included a series of 15 transects approximately orthogonal to the coast of the Gulf of Mexico and a 16th partial transect along the 27°N line between Florida and the Bahamas. On the transit between each of these transects, discrete samples were collected from the underway seawater line to obtain a comprehensive set of underway measurements. This dataset includes the data from the underway samples as well as the data from the surface sample of ech CTD cast performed along the 15 transects that were conducted during GOMECC-4.
