Surface measurements of dissolved inorganic carbon (DIC), total alkalinity (TALK), temperature, and salinity were collected during the R/V Marion-Dufresne OISO-03 cruise from 1998-12-04 to 1998-12-28. 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 synthesis projects like SOCAT and GLODAP.
Use Cases
- Modeling ocean carbon uptake based on DIC and TALK measurements.
- Analyzing seasonal or spatial variability in ocean acidification parameters in the Southern Ocean.
- Calibrating satellite-derived sea surface temperature and salinity data with in-situ measurements.
- Contributing to global carbon budget assessments by integrating data into projects like SOCAT.
Strengths
- Data is part of a long-term observational program (OISO) initiated in 1998, providing a temporal context.
- Includes key carbon cycle parameters (DIC, TALK, pCO2) alongside physical measurements (temperature, salinity).
- Data is integrated into major international synthesis projects (SOCAT, GLODAP), indicating quality and interoperability.
Limitations
- Last updated 1998-12-28 00:00:00; freshness should be verified.
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
