Continuous sea surface measurements of partial pressure of carbon dioxide (pCO2), temperature, salinity, and atmospheric pressure were collected during the R/V Marion Dufresne OISO-30 cruise from January 6 to February 1, 2020. The OISO program, initiated in 1998, collects pCO2 and associated parameters along repeated lines in the South-Western Indian and Southern Oceans. These data are regularly included in international data syntheses 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.
- Validating international carbon data syntheses (SOCAT, GLODAP) based on repeated cruise line measurements.
- Studying seasonal or regional variability in the South-Western Indian Ocean based on the 2020 cruise data.
Strengths
- Data collected during a specific 27-day cruise (2020-01-06 to 2020-02-01) providing a temporal snapshot.
- Part of a long-term observation program (OISO) initiated in 1998, suggesting consistent methodology.
- Includes multiple associated parameters (temperature, salinity, atmospheric pressure) alongside the primary pCO2 measurement.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
