CLIVAR_OISO05 dataset contains discrete profile measurements of dissolved inorganic carbon, total alkalinity, temperature, salinity, dissolved oxygen, and nutrients from the R/V Marion Dufresne cruise OISO-05. The data were collected by researchers from Sorbonne University in the Indian Ocean from July 19 to August 16, 2000, as part of the International CLIVAR Global Ocean Carbon and Repeat Hydrography Program. The program aims to quantify changes in the storage and transport of heat, fresh water, and carbon dioxide.
Use Cases
- Modeling ocean carbon uptake based on dissolved inorganic carbon and total alkalinity measurements.
- Analyzing ocean acidification trends in the Indian Ocean based on carbonate system parameters.
- Studying water mass properties and circulation using concurrent temperature, salinity, and oxygen profiles.
- Investigating nutrient distributions and their relationship to biological activity based on nutrient data.
Strengths
- Data collected as part of a systematic, international repeat hydrography program (CLIVAR).
- Includes multiple co-located chemical and physical parameters (DIC, alkalinity, oxygen, nutrients, temperature, salinity).
- Specific temporal coverage from 2000-07-19 to 2000-08-16.
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 geographic bias inherent to the specific cruise track in the Indian Ocean.
