Total alkalinity, water temperature, salinity and other variables collected from profile discrete observations using flow through pump, CTD, Niskin Bottles and other instruments during NOAA Ship Gordon Gunter cruise GU0802 Leg2 (EXPOCODE 33GG20080512), in the Gulf of Mexico from 2008-05-12 to 2008-05-30 (NCEI Accession 0240314)

This dataset contains profile discrete measurements of total alkalinity, water temperature, salinity and other variables collected from profile discrete observations using flow through pump, CTD, Niskin Bottles and other instruments during the NOAA Ship Gordon Gunter cruise GU0802 Leg2 (EXPOCODE 33GG20080512), in the Gulf of Mexico from 2008-05-12 to 2008-05-30. 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.
