Indian Ocean discrete profile measurements of dissolved inorganic carbon, total alkalinity, temperature, salinity, dissolved oxygen, nutrients, and isotopic ratios collected during the R/V Marion Dufresne cruise OISO-01 from January to February 1998. The data were gathered by researchers from Universite Pierre et Marie Curie as part of the CLIVAR_OISO01 dataset.
Use Cases
- Analyze dissolved inorganic carbon (DIC) and total alkalinity relationships with temperature and salinity to study ocean acidification.
- Model carbon dioxide (CO2) storage changes using profile measurements of DIC and delta C13 across the cruise's geospatial track.
- Correlate dissolved oxygen levels with nutrient concentrations to assess biological activity and water column ventilation.
- Use temperature and salinity profiles alongside isotopic data (delta O18) to trace water mass origins and mixing processes.
Strengths
- Profile measurements include multiple key variables: DIC, alkalinity, temperature, salinity, oxygen, nutrients, and isotopes.
- Data collected during a dedicated scientific cruise (OISO-01) under the International CLIVAR Global Ocean Carbon and Repeat Hydrography Program.
Limitations
- Data is from a single cruise in 1998, providing a snapshot rather than long-term temporal coverage.
- Sample size and spatial extent are limited to the specific track of the R/V Marion Dufresne during the one-month expedition.
