Discrete profile measurements of dissolved inorganic carbon, alkalinity, pH, temperature, salinity, dissolved oxygen, nutrients, chlorofluorocarbons, and carbon isotopes were collected during the R/V Mirai cruise CLIVAR_I03I04 in the Indian Ocean from December 9, 2003 to January 24, 2004. The data were collected by researchers from JAMSTEC and the Meteorological Research Institute as part of the CLIVAR Global Ocean Carbon and Repeat Hydrography Program. This program systematically re-occupies select WOCE/JGOFS sections to quantify changes in heat, freshwater, and carbon dioxide storage and transport.
Use Cases
- Model ocean carbon storage and transport based on dissolved inorganic carbon and alkalinity measurements.
- Study ocean acidification trends based on pH on total scale data.
- Analyze chlorofluorocarbon distributions for ocean ventilation studies based on CFC-11, CFC-12, and CFC113 data.
- Investigate nutrient cycling in the Indian Ocean based on nitrate and nitrite measurements.
- Calibrate biogeochemical models using carbon isotope ratios based on delta C13 and delta C14 data.
Strengths
- Data covers a specific cruise from December 9, 2003 to January 24, 2004.
- Includes multiple co-located chemical and physical parameters such as DIC, alkalinity, pH, temperature, salinity, and nutrients.
- Associated with the international CLIVAR Global Ocean Carbon and Repeat Hydrography Program.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data may reflect temporal bias inherent to a single cruise in 2003-2004.
