Sea surface measurements of dissolved inorganic carbon (DIC), total alkalinity (TALK), temperature and salinity during the R/V Marion-Dufresne Ocean Indien Service d'Observations - 21 (OISO-21) cruise (EXPOCODE 35MF20120125) in the Indian Ocean from 2012-01-25 to 2012-03-07 (NCEI Accession 0177325)

This NCEI accession consists of surface measurements of dissolved inorganic carbon (DIC), total alkalinity (TALK), temperature and salinity during the R/V Marion-Dufresne Ocean Indien Service d'Observations - 21 (OISO-21) cruise (EXPOCODE 35MF20120125) in the Indian Ocean from 2012-01-25 to 2012-03-07. The OISO program (Océan Indien Service d'Observations), initiated in 1998, collects measurements of pCO2 and associated parameters (T, S, DIC, TALK, nutrients, Chl-a, 13C) along the repeated lines of R.V. Marion-Dufresne in the South-Western Indian and Southern Oceans; this coverage is a complement of the international CO2 observing system (IOCCP). The OISO data are regularly included in international synthesis (SOCAT, GLODAP).
