Dissolved inorganic carbon (DIC), total alkalinity, pH on sea water scale and other hydrographic and chemical variables collected from discrete samples and profile observations during NOAA Ship Ronald H. Brown cruise along the Global Ocean Ship-Based Hydrographic Investigation Program (GO-SHIP) Section I07N (EXPOCODE 33RO20180423) in the Indian Ocean on from 2018-04-23 to 2018-06-06 (NCEI Accession 0189249)

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: May 06, 2026 at 02:23 AM | Dataset Last Updated: March 18, 2021 at 12:00 AM
This dataset includes discrete profile measurements of Dissolved inorganic carbon (DIC), total alkalinity, pH on sea water scale, dissolved organic carbon (DOC), chlorofluorocarbons (CFC-11, CFC-12), temperature, salinity, oxygen, nutrients, and other variables measured during NOAA Ship Ronald H. Brown cruise along the Global Ocean Ship-Based Hydrographic Investigation Program (GO-SHIP) Section I07N (EXPOCODE 33RO20180423) in the Indian Ocean on from 2018-04-23 to 2018-06-06. Hydrographic measurements were carried out along the I07N section in the western Indian Ocean in April-June 2018 under the auspices of GO-SHIP. The unique aspect of the 2018 I07N research cruise is that it was the first reoccupation of the I07N section since 1995. The section was not revisited for about 23 years because of the rise of piracy in the region.
