Indian Ocean Carbon and Nutrient Profiles from the TANGAROA, February-March 2002

From February 6 to March 7, 2002, the R/V TANGAROA collected discrete sample and profile data in the Indian Ocean during cruise JARE43/CARINA/61TG20020206. The dataset includes measurements of dissolved inorganic carbon, dissolved oxygen, nutrients, chlorophyll A, salinity, and temperature. It was collected by researchers from the Meteorological Research Institute and Hokkaido University as part of the CARINA international synthesis project for biogeochemical investigations.

Use Cases

• Modeling ocean carbon uptake and acidification based on dissolved inorganic carbon and alkalinity measurements.
• Analyzing nutrient cycling and primary productivity relationships based on nitrate, phosphate, silicate, and chlorophyll A data.
• Studying water mass properties and oceanographic fronts using concurrent salinity, temperature, and hydrostatic pressure profiles.

Strengths

• Data is part of the CARINA international synthesis project, aimed at producing an internally consistent dataset for carbon system studies.
• Includes a specific suite of 12 key biogeochemical variables such as dissolved inorganic carbon, nutrients, and chlorophyll.
• Covers a defined one-month temporal window and a specific geographic region (Indian Ocean).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
