Ocean Surface Carbon Dioxide Measurements from the Aurora Australis, 2011

Partial pressure of carbon dioxide and related variables were collected from the AURORA AUSTRALIS research vessel across the Indian Ocean, South Pacific Ocean, and Tasman Sea during 2011. The data include sea surface temperature, salinity, wind speed, and barometric pressure, gathered using carbon dioxide gas analyzers and thermosalinographs. Bronte Tilbrook of the Commonwealth Scientific and Industrial Research Organization collected this data as part of the VOS_Aurora_Australis_AA_2011 voyages.

Use Cases

• Modeling air-sea carbon dioxide flux based on partial pressure differences.
• Analyzing correlations between sea surface temperature and carbon dioxide concentrations.
• Studying seasonal or regional variations in oceanic carbon uptake.
• Validating satellite-derived sea surface salinity and temperature measurements.

Strengths

• Data covers multiple ocean basins (Indian Ocean, South Pacific Ocean, Tasman Sea).
• Includes multiple related variables (carbon dioxide, salinity, temperature, wind) for concurrent analysis.
• Collected over a nearly year-long period from 2011-01-04 to 2011-11-28.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Last updated 2011-11-28; freshness should be verified.
• Row count is unknown, which may limit suitability assessment.
