Continuous sea surface measurements of partial pressure of CO2, temperature, and salinity were collected during the R/V Marion Dufresne OISO-26 cruise from 2016-10-08 to 2016-10-28. The OISO program, initiated in 1998 and supported by INSU/CNRS, collects CO2 and associated parameters along repeated lines in the South-Western Indian and Southern Oceans. This data contributes to the international CO2 observing system and is included in SOCAT and GLODAP syntheses.
Use Cases
- Model oceanic carbon uptake based on continuous pCO2 measurements.
- Analyze sea surface temperature and salinity correlations with CO2 levels.
- Validate global carbon cycle models using data from the international SOCAT synthesis.
- Study biogeochemical processes in the Southern Ocean based on associated nutrient and chlorophyll-a parameters.
Strengths
- Data is part of a long-term program initiated in 1998, providing temporal context.
- Includes multiple associated parameters such as dissolved inorganic carbon, alkalinity, oxygen, nutrients, and chlorophyll-a.
- Data is integrated into international synthesis products SOCAT and GLODAP, indicating quality checks.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Last updated 2016-10-28; freshness should be verified.
- Row count is unknown, which may limit suitability assessment.
