Dissolved inorganic carbon, total alkalinity, pH on Total Scale, nutrients and other variables collected from profile and discrete sample observations using CTD, Niskin bottle and other instruments during NOAA Ship Gordon Gunter cruises in the Gulf of Maine, Georges Bank, and Mid-Atlantic Bight from 2016-05-21 to 2016-06-20 (NCEI Accession 0168902)

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: July 28, 2026 at 07:56 PM | Dataset Last Updated: June 04, 2022 at 12:00 AM

This dataset contains dissolved inorganic carbon, Total alkalinity, pH on Total Scale, nutrients and other variables measured from profile discrete measurement in the Northeast coast of the US. Increasing amounts of atmospheric carbon dioxide from human industrial activities are causing changes in global ocean carbon chemistry 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. This effort is in support of the coastal monitoring and research objectives of the NOAA Ocean Acidification Program (OAP).
