The OISO-29 cruise dataset includes continuous sea surface measurements of partial pressure of carbon dioxide (pCO2), temperature, salinity, and atmospheric pressure. The data were collected by the R/V Marion Dufresne in the Indian Ocean from January 9 to February 8, 2019. The OISO program, supported by INSU/CNRS, contributes to international synthesis efforts like SOCAT and GLODAP.
Use Cases
- Modeling ocean carbon uptake based on continuous pCO2 measurements.
- Analyzing sea surface temperature and salinity correlations with carbon dioxide levels.
- Contributing to international carbon data synthesis (SOCAT, GLODAP) based on the program's stated purpose.
- Studying seasonal or regional variations in the South-Western Indian and Southern Oceans based on repeated cruise lines.
Strengths
- Data collection spans a specific 31-day period from 2019-01-09 to 2019-02-08.
- Part of a long-term observational program (OISO) initiated in 1998.
- Includes continuous measurements of multiple parameters (pCO2, temperature, salinity, atmospheric pressure).
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Last updated 2019-02-08 00:00:00; freshness should be verified.
- Row count is unknown, which may limit suitability assessment.
