Dissolved inorganic carbon, total alkalinity, nutrients, and other variables collected from profile and discrete observations using Niskin bottle and other instruments from NOAA Ship Henry B. Bigelow in Gulf of Maine, Georges Bank, and Mid-Atlantic Bight from 2015-05-20 to 2015-06-02 (NCEI Accession 0157024)

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Metadata Last Checked: January 29, 2026 | Last Modified: 2022-06-04T00:00:00.000+00:00
This dataset contains profile discrete measurements of dissolved inorganic carbon, total alkalinity, nutrients, and chlorophyll a in Mid-Atlantic Bight and Gulf of Maine. 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).
