CLIVAR_OISO02 dataset contains 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-02 in the Indian Ocean from August 18 to September 9, 1998. The data were collected by Claire Lo Monaco and Nicolas Metzl of Sorbonne University 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, carbon dioxide, and related parameters.
Use Cases
- Modeling ocean carbon uptake and storage based on dissolved inorganic carbon and total alkalinity measurements.
- Analyzing changes in ocean biogeochemistry based on nutrient and dissolved oxygen profiles.
- Studying isotopic signatures of carbon and oxygen in seawater based on delta C13 and delta O18 data.
- Investigating physical oceanographic properties based on temperature and salinity profiles.
Strengths
- Data collected during a dedicated research cruise over a specific 22-day period in 1998.
- Includes multiple correlated parameters (carbon, alkalinity, nutrients, isotopes, temperature, salinity) for comprehensive oceanographic analysis.
- Part of a systematic global program (CLIVAR) designed for repeat observations and change quantification.
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 a single cruise track in the Indian Ocean.
