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 - 22 (OISO-22) cruise (EXPOCODE 35MV20130209) in the Indian Ocean from 2013-02-09 to 2013-03-10 (NCEI Accession 0173575)

PACKAGE DESCRIPTION: This dataset 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 - 22 (OISO-22) cruise (EXPOCODE 35MV20130209) in the Indian Ocean from 2013-02-09 to 2013-03-10. The OISO program, initiated in 1998, collects measurements of partial pressure of carbon dioxide (pCO2) and associated parameters (temperature, salinity, DIC, TALK, nutrients, chlorophyll and 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 Ocean Carbon Coordination Project (IOCCP). The OISO data are regularly included in international data synthesis projects as Surface Ocean CO2 Atlas (SOCAT) and Global Ocean Data Analysis Project (GLODAP).
