Surface underway data collected from the R/V Marion Dufresne during the OISO-8 cruise in the Indian and Southern Oceans from 2002-01-05 to 2002-01-29. The dataset includes measurements of the partial pressure of carbon dioxide, salinity, temperature, and barometric pressure. Principal investigator Nicolas Metzl of LOCEAN-IPSL led the cruise, which used instruments like a CO2 gas analyzer and equilibrator.
Use Cases
- Modeling air-sea carbon dioxide exchange based on partial pressure of CO2 (fCO2) measurements.
- Analyzing correlations between sea surface temperature and salinity with CO2 levels.
- Studying seasonal or regional variability in ocean surface chemistry in the Indian Ocean.
- Validating satellite-derived ocean carbon data with in-situ barometric pressure and temperature readings.
Strengths
- Data includes multiple concurrent ocean surface variables: fCO2, salinity, temperature, and barometric pressure.
- Specific cruise and principal investigator (Nicolas Metzl, LOCEAN-IPSL) are identified, providing clear provenance.
- Temporal coverage is precisely defined from 2002-01-05 to 2002-01-29.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data may reflect geographic/temporal bias inherent to a single 2002 cruise track.
