Aurora Australis 1993 Underway Oceanographic Measurements

August to October 1993 data from the Aurora Australis THIRST voyage, logged at 10-second intervals. The dataset includes underway measurements from a manned marine science expedition traveling between Hobart, Macquarie Island, and Heard Island. It was collected by the Australian Antarctic Division (AU_AADC).

Use Cases

• Analyze temporal patterns in DLS (Data Logging System) parameters recorded at 10-second intervals along the voyage track.
• Correlate XBT (Expendable Bathythermograph) data with geographic position on transit legs to and from Hobart.
• Study CTD (Conductivity, Temperature, Depth) profiles collected in the waters around Heard Island.
• Use the scanned track plot to visualize the vessel's path and data collection locations from 28 August to 28 September 1993.

Strengths

• High-frequency data logging at 10-second intervals for DLS measurements.
• Multi-instrument dataset combining underway DLS, XBT, and CTD data.
• Clear temporal coverage from August to October 1993.

Limitations

• Unknown total row count and specific column schema for the underway data.
• Data is temporally stale, last updated in October 1993.
• Geographic scope is limited to the specific voyage track in the Southern Ocean.
