Dissolved inorganic carbon, total alkalinity, pH on total scale, water temperature, salinity and other variables collected from profile discrete observations using flow through pump, CTD, Niskin Bottles and other instruments during the F.G. Walton Smith CIOERT2017 cruise WS17135 (EXPOCODE 33WA20170515), in the Gulf of Mexico, Caribbean Sea and North Atlantic Ocean from 2017-05-15 to 2017-06-13 (NCEI Accession 0240205)

This dataset contains profile discrete measurements of dissolved inorganic carbon, total alkalinity, pH on total scale, water temperature, salinity and other variables collected from profile discrete observations using flow through pump, CTD, Niskin Bottles and other instruments during the F.G. Walton Smith CIOERT2017 cruise WS17135 (EXPOCODE 33WA20170515), in the Gulf of Mexico, Caribbean Sea and North Atlantic Ocean from 2017-05-15 to 2017-06-13. Increasing amounts of atmospheric carbon dioxide from human industrial activities are causing changes in global ocean carbon chemistry. Through the SOOP program we measure air and ocean surface pCO2 and take discrete samples of other carbon parameters. This effort is in support of the coastal monitoring and research objectives of the NOAA Ocean Acidification Program (OAP) and the Climate Program Office.
