    • Dissolved inorganic carbon, total alkalinity, pH on total scale, and other variables collected from discrete samples and profile observations during the R/V F. G. Walton Smith cruise FC2507 (EXPOCODE 33WA20250703) in the East Coast of the US, North Atlantic Ocean on 2025-07-03 (NCEI Accession 0309256)

    Metadata Updated: January 1, 2026

    This dataset consists of water temperature, salinity, nutrients, dissolved inorganic carbon, total alkalinity, pH on total scale, and other variables collected from discrete samples and profile observations during the R/V F. G. Walton Smith cruise FC2507 (EXPOCODE 33WA20250703) in the East Coast of the US, North Atlantic Ocean on 2025-07-03. Understanding of carbon transport and ocean acidification along the US East Coast, particularly in the Florida Straits, is currently limited by insufficient carbon chemistry data. To close this critical gap, the Role of the Overturning Circulation in Carbon Accumulation (ROCCA) project leverages the observations and logistics of NOAA’s established Western Boundary Time Series (WBTS) project at approximately 27N. This effort is obtaining new, high-quality measurements of carbonate chemistry (dissolved inorganic carbon, total alkalinity, and pH on the total scale) and associated parameters (nutrients). The resulting comprehensive dataset is being used to accurately estimate anthropogenic carbon transports across the subtropical North Atlantic and to determine the contributions of air-sea fluxes and ocean circulation to regional carbon accumulation.

    Licence accessLevel: Public, Inorganic carbon data from the ROCCA cruises are made freely available to the public and the scientific community in the belief that their wide dissemination will lead to greater understanding and new scientific and policy insights. The investigators sharing these data rely on the ethics and integrity of the user to ensure that the institutions and investigators involved in producing these data sets receive fair credit for their work, which in turn helps ensure the continuity of the observational time-series. If the data are obtained for potential use in a publication or presentation, we urge the end user to inform the investigators at the outset of this work so that we can help ensure that the quality and limitations of the data are accurately represented. If these data are essential to the work, or if an important result or conclusion depends on these data, co-authorship may be appropriate. This should be discussed at an early stage in the work. We request that manuscripts using these data be shared before they are submitted for publication. Please direct all queries about this data set to Drs. Leticia Barbero (leticia.barbero@noaa.gov), Denis Volkov (Denis.Volkov@noaa.gov) and Peter Brown (peter.brown@noc.ac.uk).
