OISO-02 Cruise: Surface Ocean Carbon Measurements

The Indian Ocean and Southern Ocean contain surface measurements of dissolved inorganic carbon, total alkalinity, temperature, and salinity collected during the R/V Marion-Dufresne OISO-02 cruise from August 19 to September 7, 1998. This dataset is part of the Ocean Indien Service d'Observations (OISO) program, initiated in 1998, which collects pCO2 and associated parameters along repeated ship tracks. The data are regularly included in international synthesis projects like the Surface Ocean CO2 Atlas (SOCAT) and the Global Ocean Data Analysis Project (GLODAP).

Use Cases

• Calculating ocean carbon uptake based on dissolved inorganic carbon and alkalinity measurements
• Assessing ocean acidification trends in the Southern Ocean using pH derived from carbonate system parameters
• Validating and contributing to global carbon data syntheses like SOCAT and GLODAP
• Studying biogeochemical cycles by analyzing co-measured nutrients and chlorophyll

Strengths

• Data is part of a long-term, repeated-line observation program (OISO) initiated in 1998
• Dataset is integrated into major international synthesis projects (SOCAT and GLODAP)
• Provides a complement to the International Ocean Carbon Coordination Project (IOCCP)

Limitations

• Column names and exact data structure are unknown from available metadata
• Row count, file size, and license information are not provided by any source
• Data is from a single cruise in 1998, representing a snapshot rather than a long time series
