Dissolved inorganic carbon, total alkalinity, pH, nutrients, and other variables collected from profile and discrete observations using Niskin bottle and other instruments from NOAA Ship Gordon Gunter on the northeastern U.S. continental shelf, Gulf of Maine, coastal waters of Canada, Greenland and Iceland from 2015-10-13 to 2015-10-24 (NCEI Accession 0157023)

This dataset contains profile discrete measurements of dissolved inorganic carbon, total alkalinity, pH, dissolved oxygen, and nutrients in the North Atlantic Ocean. 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).
