    • Dissolved inorganic carbon (DIC), total alkalinity (TA), pH on total scale, dissolved organic carbon (DOC), chlorofluorocarbons (CFC11, CFC12, CFC113), water temperature, salinity, dissolved oxygen, nutrients and other hydrographic and chemical variables collected from discrete samples and profile observations during the R/V Thomas G. Thompson cruise on GO-SHIP repeat section I08S (EXPOCODE 325020240221) in the Indian Ocean, Southern Ocean from 2024-02-21 to 2024-04-01 (NCEI Accession 0308102)

    This dataset includes discrete profile measurements of Dissolved inorganic carbon (DIC), total alkalinity (TA), pH on total scale, dissolved organic carbon (DOC), chlorofluorocarbons (CFC11, CFC12, CFC113), water temperature, salinity, dissolved oxygen, nutrients and other hydrographic and chemical variables collected from discrete samples and profile observations during the R/V Thomas G. Thompson cruise on GO-SHIP repeat section I08S (EXPOCODE 325020240221) in the Indian Ocean, Southern Ocean from 2024-02-21 to 2024-04-01. GO-SHIP repeat transoceanic surveys (www.goship.org) provide full water column hydrographic observations with temporal and spatial resolutions adequate to resolve decadal variability in oceanic storage of heat, freshwater, carbon, oxygen, nutrients and transient tracers. Repeat hydrographic physical-biogeochemical measurements nominally in Indian Ocean enables scientists to better tackle important unresolved aspects of the Indian and Southern Ocean's response to decadal scale variability and increases in both heat and carbon dioxide as a result of anthropogenic activities. The I08S 2024 cruise aboard the UNOLS vessel R/V Thomas G. Thompson was undertaken as part of the US GO-SHIP (Global Ocean Ship-based Hydrographic Investigations Program), a major contributor to international GO-SHIP. The program’s overall objective is to collect quasi-decadal, highly accurate, surface-to-bottom, coast-to-coast, physical, and chemical oceanic observations. These measurements are essential to monitoring long-term changes in heat, freshwater, carbon, oxygen, and other tracers in the global ocean, the main reservoir in the Earth System.
