Southern Ocean Sea Surface and Atmospheric CO2 Measurements from 2017-2018

Surface underway, chemical, meteorological and physical data collected from the R/V Aurora Australis research vessel between 2017-01-25 and 2018-01-11. The data include air-sea difference of partial pressure of carbon dioxide (pCO2), barometric pressure, pCO2 in atmosphere and water, sea surface salinity, temperature, and wind speed and direction. These data were collected by researchers Bronte Tilbrook, John Akl, and Craig Neill of the Commonwealth Scientific and Industrial Research Organization.

Use Cases

• Modeling ocean carbon uptake based on air-sea pCO2 difference data.
• Analyzing seasonal variability in sea surface temperature and salinity in the Southern Ocean.
• Correlating atmospheric pCO2 measurements with wind speed and direction data.
• Studying the Southern Ocean's role in the global carbon cycle using underway surface data.

Strengths

• Data collected over a full annual cycle from 2017-01-25 to 2018-01-11.
• Includes multiple related variables: pCO2 in air and water, salinity, temperature, and wind data.
• Data originates from a specific research vessel (R/V Aurora Australis) and named principal investigators.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
