Aurora Australis Maiden Voyage Underway Ocean Data 1990

Aurora Australis Voyage 7.2 (HIMS) 1989-90 Underway Data contains oceanographic observations logged at 60-second intervals. The dataset covers the ship's maiden science voyage from Hobart to Heard Island and back between May and July 1990. Data was collected by the Australian Antarctic Data Centre (AU_AADC) during a manned marine science expedition.

Use Cases

• Analyze temporal patterns in DLS data types recorded at 60-second intervals along the voyage track.
• Map the geospatial track and environmental conditions between Hobart and Heard Island from May to July 1990.
• Correlate underway sensor data with the scanned printed plot of the voyage track in the Heard Island area (18 May to 14 June 1990).
• Study the initial performance and data collection of the Aurora Australis during its maiden scientific cruise.

Strengths

• High-frequency data logging at 60-second intervals provides detailed temporal resolution.
• Includes a scanned printed plot providing visual reference for a section of the voyage track.
• Covers a complete round-trip voyage between Hobart and Heard Island over approximately two months.

Limitations

• Specific data columns, variables, and total row count are unknown from the description.
• Data is from a single voyage in 1990, limiting temporal scope and modern applicability.
• The primary dataset format and file structure are unspecified.
