Aurora Australis 2013 Underway Ocean Carbon and Meteorological Data

From January 13 to December 7, 2013, the research vessel Aurora Australis collected surface underway measurements of carbon dioxide partial pressure, salinity, temperature, and meteorological variables across the Indian Ocean, South Pacific Ocean, Southern Ocean, and Tasman Sea. The dataset, compiled by researchers from the Commonwealth Scientific and Industrial Research Organization (CSIRO), includes interpolated atmospheric and seawater carbon dioxide values alongside wind and sea surface conditions. It is associated with three specific cruise identifiers: 09AR20130113, 09AR20130228, and 09AR20131015.

Use Cases

• Calculating air-sea carbon dioxide flux based on partial pressure differences.
• Analyzing spatial and temporal variability of sea surface temperature and salinity in the Southern Ocean.
• Validating ocean carbon cycle models using in-situ pCO2 measurements.
• Studying the relationship between wind speed/direction and surface ocean properties.

Strengths

• Data collection spans nearly a full year, from January to December 2013.
• Includes specific, high-quality instrument details such as shower head chamber equilibrators and thermosalinographs.
• Geographic coverage is explicitly defined across multiple ocean basins, including the Southern Ocean (>60°S).

Limitations

• Key metadata such as row count, file size, and license are not provided on any platform.
• The column list is marked as 'unknown' across all sources, limiting precise understanding of data structure.
• There is a conflict in the 'last updated' metadata between platforms (2013 vs. 2026).
