OISO-6: Surface Ocean Carbon Measurements in the Indian and Southern Oceans, 2001

OISO-6 cruise data includes surface underway measurements of the partial pressure of carbon dioxide, salinity, temperature, and barometric pressure collected from the R/V Marion Dufresne in the Indian Ocean from 2001-01-04 to 2001-01 25. Principal investigator Nicolas Metzl of LOCEAN-IPSL led the cruise. The data were collected using instruments including a barometric pressure sensor, CO2 gas analyzer, and thin film equilibrator.

Use Cases

• Modeling air-sea carbon dioxide exchange based on partial pressure of CO2 (fCO2) measurements.
• Analyzing ocean surface chemistry variability based on concurrent salinity and temperature data.
• Studying regional carbon dynamics in the Indian and Southern Oceans based on the spatial cruise track.
• Calibrating or validating satellite-derived sea surface temperature or salinity products based on in-situ measurements.

Strengths

• Data includes multiple concurrent oceanographic variables: fCO2, salinity, temperature, and barometric pressure.
• Specific instruments used are documented: barometric pressure sensor, CO2 gas analyzer, and thin film equilibrator.
• Cruise has a defined temporal coverage from 2001-01-04 to 2001-01-25.
• Principal investigator and research vessel are explicitly named.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
• Data may reflect geographic and temporal bias inherent to a single three-week cruise.
