    • 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 WS25024 (EXPOCODE 33WA20250124) in the North Atlantic Ocean and Gulf of America from 2025-01-24 to 2025-01-31 (NCEI Accession 0309259)

    Metadata Updated: March 1, 2026

    This dataset consists of 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 WS25024 (EXPOCODE 33WA20250124) in the North Atlantic Ocean and Gulf of America from from 2025-01-24 to 2025-01-31. Near-shore estuarine and coastal regions are where most recreational fishing and tourism occur, yet they are vastly under-sampled. Their susceptibility to OA is not well understood due to their high biogeochemical variability. These regions are affected by land-side processes such as river discharge and run-offs and ocean-side processes through slope water exchange. A full determination of the carbonate system in these regions in conjunction with open ocean measurements is needed to increase our understanding of the effects of OA on ocean health and fisheries and our ability to predict them. In this project, we propose to augment several observational campaigns by 1) adding a carbonate component to the harmful algal blooms (HABs) monitoring cruises conducted periodically on the Western Florida Shelf in order to study potential links between HABs and OA, 2) renewing our collaboration with select National Parks to complement and enhance our near-shore data collection on the Northern Gulf of America and US East Coast, and 3) complementing our underway surface pCO2 measurements in the Gulf of America and US East Coast with underway total alkalinity measurements to help us improve our fundamental understanding of nearshore OA processes. The addition of these measurements to the current assets already present in the region would enhance our understanding of the linkage between nearshore and open ocean processes and better assess the mechanisms and impacts of OA on the biogeochemistry, biology and their economic consequences.

    Licence accessLevel: Public, Inorganic carbon data from the SFER 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) and Denis Pierrot (denis.pierrot@noaa.gov).
