abstract: This dataset is part of the long-term monitoring program OISO (Ocean Indien Service d'Observations) initiated in 1998, and covering contrasting regions in the South-West Indian Ocean from the subtropics to the Antarctic zone. 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).
purpose: 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

code: carbon dioxide (CO2) gas analyzer
type: carbon dioxide (CO2) gas analyzer
description: 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.
