Surface measurements of dissolved inorganic carbon, total alkalinity, temperature, and salinity collected during the R/V Marion-Dufresne OISO-01 cruise from January 21 to February 17, 1998. The data are part of the OISO program initiated in 1998 and are regularly included in international synthesis projects like SOCAT and GLODAP. The cruise track covered the Indian and Southern Ocean.
Use Cases
- Calibrating ocean carbon models based on direct DIC and alkalinity measurements.
- Analyzing seasonal or spatial variability of surface ocean CO2 parameters in the Southern Ocean.
- Validating satellite-derived sea surface salinity and temperature products with in-situ cruise data.
- Contributing to global carbon budget assessments through integration into SOCAT or GLODAP.
Strengths
- Data is part of a long-term observational program (OISO) initiated in 1998.
- Measurements are integrated into major international data synthesis projects (SOCAT, GLODAP).
- Cruise provides a specific temporal snapshot from January 21 to February 17, 1998.
Limitations
- Description metadata is limited; actual data quality requires manual inspection after download.
- Column-level documentation is absent; field semantics must be inferred after download.
- Last updated 1998-02-17 00:00:00; freshness should be verified.
