This dataset includes profile discrete measurements of dissolved inorganic carbon (DIC), total alkalinity, chlorofluorocarbons, CTD temperature, CTD salinity, CTD oxygen, chlorofluorocarbons (CFC) and other measurements obtained during the R/V Knorr cruise (EXPOCODE 316N20150906) in Davis Strait from 2015-09-06 to 2015-09-24.

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.

This dataset contains dissolved inorganic carbon, total alkalinity, pH on total scale, nutrients and other variables measured from profile discrete observations during the R/V Hugh R. Sharp cruise S11802 (EXPOCODE 33H520181102) in the North Atlantic Ocean, Gulf of Maine, Georges Bank, and Mid-Atlantic Bight from 2018-11-02 to 2018-11-12. Increasing amounts of atmospheric carbon dioxide from human industrial activities are causing changes in global ocean carbon chemistry ultimately resulting in a reduction in pH, a process termed ocean acidification. Studies have demonstrated adverse effects on calcifying organisms, particularly some invertebrates, corals, sea urchins, pteropods, and coccolithophores, but also on species of commercial interest such as oysters or crabs. In support of the coastal monitoring and research objectives of the NOAA Ocean Acidification Program (OAP), the Ecosystem Monitoring Cruises (ECOMON) are utilized to collect water samples to measure water column inorganic carbon and hydrographic parameters including nutrients. Samples are collected at three depths (surface, mid-depth and near bottom) at select stations on a quarterly basis in the northeastern Atlantic continental shelf region of the United States. Water samples are sent to and analyzed by scientists at the Atlantic Oceanographic and Meteorological Laboratory (AOML) for dissolved inorganic carbon, pH and total alkalinity concentrations. Additional samples are analyzed for nutrient concentrations at the University of Maine. These data are used to monitor short-long term coastal ocean acidification trends.
