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 - 8 (OISO-08) cruise (EXPOCODE 35MV20020104) in the Indian Ocean from 2002-01-04 to 2002-01-29 (NCEI Accession 0173476)

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 - 8 (OISO-08) cruise (EXPOCODE 35MV20020104) in the Indian Ocean from 2002-01-04 to 2002-01-29. 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).

本数据集包含“玛丽安-迪弗雷纳号”（R/V Marion-Dufresne）研究船执行印度洋观测服务项目-8（OISO-08）科考航次（航次代码：35MV20020104）期间获取的表层海水溶解无机碳（DIC）、总碱度（TALK）、温度及盐度观测数据，观测时段为2002年1月4日至2002年1月29日，观测海域为印度洋。OISO项目于1998年启动，依托“玛丽安-迪弗雷纳号”在西南印度洋及南大洋的重复观测断面，采集二氧化碳分压（pCO2）及相关参数数据，相关参数包括温度、盐度、溶解无机碳、总碱度、营养盐、叶绿素及碳13（¹³C）；该观测覆盖范围是国际海洋碳协调计划（IOCCP）的补充性观测内容。OISO项目的观测数据会定期被纳入《表层海洋二氧化碳图集》（SOCAT）、全球海洋数据分析计划（GLODAP）等国际数据综合项目中。
