Dissolved inorganic carbon, total alkalinity, pH, and other variables collected from surface discrete observations using flow-through pump and other instruments during the M/V Equinox cruises in the North Atlantic ocean from 2015-03-07 to 2016-11-07 (NCEI Accession 0154382)

This dataset contains surface discrete measurements of dissolved inorganic carbon, total alkalinity, and pH from the east coast of Florida to Puerto Rico during the M/V Equinox cruises in the North Atlantic ocean from 2015-03-07 to 2016-11-07. 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.
