Dissolved inorganic carbon, total alkalinity, water temperature, salinity and other parameters collected from profile discrete observations using CTD, Niskin Bottles and other instruments during the R/V Knorr cruise KN2011-4 (EXPOCODE 316N20110426), in the North Atlantic Ocean from 2011-04-26 to 2011-05-02 (NCEI Accession 0240321)

This dataset contains profile discrete measurements of dissolved inorganic carbon, total alkalinity, water temperature, salinity and other parameters collected from profile discrete observations using CTD, Niskin Bottles and other instruments during the R/V Knorr cruise KN2011-4 (EXPOCODE 316N20110426), in the North Atlantic Ocean from 2011-04-26 to 2011-05-02. 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.
