Aurora Australis 1992 Underway Voyage Data

Underway data was logged at 60-second intervals from November 26 to December 7, 1992, during the Aurora Australis Voyage 4. The dataset records observations from the vessel's route between Hobart, Mawson, Davis, and Casey stations. It was collected by the Australian Antarctic Data Centre (AU_AADC) and published in December 1992.

Use Cases

• Analyze temporal patterns in NoQalms data types recorded at 60-second intervals during the first leg of the voyage.
• Map the vessel's route and associated environmental measurements between Hobart, Mawson, Davis, and Casey stations.
• Compare data collection frequency and potential variable changes between the initial high-frequency logging period and subsequent irregular 3-5 minute intervals.

Strengths

• Data logged at high 60-second intervals for a defined period from November 26 to December 7, 1992.
• Covers a specific geographic transect across multiple Antarctic research stations.

Limitations

• Sample size and specific variable columns are unknown.
• Data collection frequency became irregular (approximately 3-5 minutes) for a portion of the voyage, reducing temporal consistency.
• Dataset is temporally stale, with no updates since its creation in 1992.
