Surface underway data from the Australian research vessel Aurora Australis tracks carbon dioxide exchange between the ocean and atmosphere across the Southern Ocean and South Pacific. The dataset includes partial pressure of CO2 in air and water, sea surface temperature, salinity, wind speed, and barometric pressure, collected over a one-year period from January 2012 to January 2013. Bronte Tilbrook of Australia's Commonwealth Scientific and Industrial Research Organization led the collection effort.
Use Cases
- Modeling air-sea CO2 flux based on the difference between water and atmospheric partial pressure measurements.
- Analyzing correlations between sea surface temperature, salinity, and carbon dioxide solubility.
- Studying seasonal and spatial variability of oceanic pCO2 in the Southern Ocean.
- Calibrating or validating satellite-derived sea surface temperature and salinity products with in-situ measurements.
Strengths
- Data collection spans a full year from 2012-01-05 to 2013-01-08, covering seasonal cycles.
- Measurements cover multiple ocean basins including the Indian Ocean, South Pacific Ocean, and Southern Ocean.
- Specific instruments used are listed, including a Carbon dioxide gas analyzer and thermosalinographs.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
