Discrete profile measurements of dissolved inorganic carbon, total alkalinity, temperature, salinity, dissolved oxygen, nutrients, and isotopic ratios were collected during a 1998 research cruise in the Indian Ocean. The data were gathered by researchers from Universite Pierre et Marie Curie as part of the CLIVAR_OISO02 dataset. Observations span from August 18 to September 9, 1998.
Use Cases
- Analyze dissolved inorganic carbon (DIC) and total alkalinity profiles to assess ocean acidification trends.
- Correlate temperature and salinity measurements with nutrient concentrations to study biogeochemical processes.
- Use delta C13 and delta O18 isotopic data to trace carbon sources and water mass origins.
- Model carbon dioxide (CO2) storage changes by integrating DIC, alkalinity, and hydrographic parameters.
Strengths
- Data includes multiple key ocean carbon cycle parameters (DIC, alkalinity, nutrients, isotopes).
- Profiles collected during a dedicated research cruise following systematic CLIVAR program protocols.
Limitations
- Dataset is limited to a single cruise in 1998, providing a snapshot rather than long-term monitoring.
- Sample size is constrained to the stations visited during the 22-day expedition.
- Data is over 25 years old, limiting analysis of recent ocean change.
