It includes hydrological and biogeochemical measurements (temperature, salinity, oxygen, total CO2, alkalinity, nutrients, chlorophyll-a, d13C and d18O) collected in the water column (17 stations) using a rosette-CTD equipped with 24 Niskin bottles. Most of the samples were collected from the surface down to 1200m, except for 2 deep stations (down to the bottom at 30°S and 56.5°S). During the OISO-21 cruise we also collected underway fCO2 data (NCEI Accession 0116411), as well as underway total CO2 and alkalinity data (NCEI Accession 0177325) and complementary parameters collected in surface waters every 4h to 8h (nutrients, chlorophyll-a, d13C and d18O). The OISO data are regularly included in international data syntheses (SOCAT, GLODAP). The main objectives of this dataset are to evaluate anthropogenic CO2 and ocean acidification in the ocean interior, and to monitor changes in subsurface waters that could affect air-sea CO2 fluxes Funding Information: Institut National des Sciences de l’Univers (INSU), Institut polaire français Paul Emile Victor (IPEV), Institut Pierre Simon Laplace (IPSL), Sorbonne Universirty (Océan Indien Service d'Observations (OISO)) completed historicalArchive NOAA National Centers for Environmental Information ncei.info@noaa.gov https://www.ncei.noaa.gov/contact HTTPS NCEI Contact Information Information for contacts at NCEI. information pointOfContact asNeeded https://www.ncei.noaa.gov/access/metadata/landing-page/bin/gfx?id=gov.noaa.nodc:0290760 Preview graphic PNG 0290760 NCEI ACCESSION NUMBER 2024-04-02 publication CHLOROPHYLL A DEPTH - OBSERVATION DISSOLVED INORGANIC CARBON (DIC) DISSOLVED OXYGEN HYDROSTATIC PRESSURE nitrate + nitrite content (concentration) phosphate SALINITY silicate total alkalinity WATER TEMPERATURE theme NODC DATA TYPES THESAURUS carbon dioxide (CO2) gas analyzer CTD Niskin bottle nutrient autoanalyzer oxygen sensor temperature sensor thermosalinograph titrator instrument NODC INSTRUMENT TYPES THESAURUS biological chemical discrete sample physical profile theme NODC OBSERVATION TYPES THESAURUS Marion Dufresne platform NODC PLATFORM NAMES THESAURUS Sorbonne University dataCentre NODC COLLECTING INSTITUTION NAMES THESAURUS Sorbonne University dataCentre NODC SUBMITTING INSTITUTION NAMES THESAURUS The Global Ocean Ship-based Hydrographic Investigations Program (GO-SHIP) project NODC PROJECT NAMES THESAURUS Indian Ocean place NODC SEA AREA NAMES THESAURUS oceanography theme WMO_CategoryCode 2012-09-15 publication OISO-21 project Cruise ID 35MF20120125 project EXPOCODE Ocean Carbon and Acidification Data System (OCADS) Project project Ocean Acidification Search Keywords OISO project Reference Section ID EARTH SCIENCE > OCEANS > OCEAN CHEMISTRY > ALKALINITY EARTH SCIENCE > OCEANS > OCEAN CHEMISTRY > CHLOROPHYLL EARTH SCIENCE > OCEANS > OCEAN CHEMISTRY > INORGANIC CARBON EARTH SCIENCE > OCEANS > OCEAN CHEMISTRY > NITRATE EARTH SCIENCE > OCEANS > OCEAN CHEMISTRY > NITRITE EARTH SCIENCE > OCEANS > OCEAN CHEMISTRY > OXYGEN EARTH SCIENCE > OCEANS > OCEAN CHEMISTRY > PHOSPHATE EARTH SCIENCE > OCEANS > OCEAN CHEMISTRY > SILICATE EARTH SCIENCE > OCEANS > OCEAN PRESSURE > WATER PRESSURE EARTH SCIENCE > OCEANS > OCEAN TEMPERATURE > WATER TEMPERATURE EARTH SCIENCE > OCEANS > SALINITY/DENSITY > SALINITY theme Global Change Master Directory (GCMD) Science Keywords 2026 revision 23 Earth Science Data and Information System, Earth Science Projects Division, Goddard Space Flight Center (GSFC), National Aeronautics and Space Administration (NASA) Greenbelt MD https://forum.earthdata.nasa.gov/app.php/tag/GCMD%2BKeywords HTTPS GCMD Keyword Forum Page Global Change Master Directory (GCMD). 2025.

NOAA National Centers for Environmental Information custodian carbon dioxide (CO2) gas analyzer carbon dioxide (CO2) gas analyzer measures gaseous carbon dioxide Carbon dioxide gas analyzer has often been referred to as LI-COR, because a lot of researchers choose to use products manufactured by LI-COR incorporation for their carbon dioxide measurement. The main component of a carbon dioxide analyzer is a nondispersive infrared (NDIR) spectroscopic sensors to detect CO2 in a gaseous environment by its characteristic absorption. Carbon dioxide (CO2) gas analyzer works together with carbon dioxide (CO2) equilibrator (insttypes_id 184) to measure carbon dioxide in the water. To measure water carbon dioxide, water needs to be continuously supplied to a showerhead inside an equilibrator. As the water flows through the equilibrator chamber, dissolved carbon dioxide exchanges quickly with air in the headspace. This air is then sampled by the carbon dioxide analyzer to determine the mole fraction of CO2 in water.
