Southern Ocean Sea Surface and Atmospheric CO2 Measurements from 2016

Integrated Marine Observing System data includes surface underway chemical, meteorological, and physical measurements collected from R/V Aurora Australis and R/V Investigator. The dataset covers the Indian Ocean, South Pacific Ocean, Southern Oceans, and Tasman Sea from January 11, 2016, to January 20, 2017. Data were collected by researchers Bronte Tilbrook, John Akl, and Craig Neill of the Commonwealth Scientific and Industrial Research Organization.

Use Cases

• Modeling air-sea carbon dioxide flux based on partial pressure measurements in water and atmosphere.
• Analyzing seasonal or spatial variability in sea surface temperature and salinity in the Southern Ocean.
• Correlating wind speed and direction with atmospheric carbon dioxide concentrations.
• Studying Southern Ocean carbon sink dynamics based on underway fCO2 measurements.

Strengths

• Data collected over a full year from January 2016 to January 2017.
• Includes simultaneous measurements of sea surface and atmospheric carbon dioxide partial pressure.
• Covers multiple ocean regions: Indian Ocean, South Pacific Ocean, Southern Oceans, and Tasman Sea.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data format is listed as HTML, which may require parsing to extract structured data.
