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 - 25 (OISO-25) cruise (EXPOCODE 35MV20160107) in the Indian Ocean from 2016-01-07 to 2016-01-26 (NCEI Accession 0177402)

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 - 25 (OISO-25) cruise (EXPOCODE 35MV20160107) in the Indian Ocean from 2016-01-07 to 2016-01-26. 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).

这个数据集包含2016年1月7日至2016年1月26日期间，“马里恩-迪弗雷纳”号科考船（R/V Marion-Dufresne）在印度洋开展的印度洋观测服务-25航次（OISO-25，科考编码EXPOCODE：35MV20160107）中获取的表层水体溶解无机碳（DIC）、总碱度（TALK）、温度及盐度测量数据。OISO计划（即印度洋观测服务，Océan Indien Service d'Observations）始于1998年，旨在通过“马里恩-迪弗雷纳”号科考船在西南印度洋及南大洋的固定航线，采集海水二氧化碳分压（pCO₂）及相关参数（温度T、盐度S、溶解无机碳DIC、总碱度TALK、营养盐、叶绿素a、碳-13）的测量数据；该观测网络是国际二氧化碳观测系统（IOCCP）的补充部分。OISO数据定期被纳入国际综合数据集（如SOCAT、GLODAP）。
