Underway Oceanographic Data From 1995 Antarctic Resupply Cruise

A 1995 Antarctic resupply voyage of the Aurora Australis collected underway oceanographic data at 20-second intervals. Observations were logged between August and October 1995 on the route from Hobart to Macquarie Island to Davis Station and back. The dataset was produced by the Australian Antarctic Data Centre.

Use Cases

• Analyzing temporal patterns in NoQalms data types at 20-second resolution for the voyage duration.
• Correlating underway sensor readings with the ship's geographic track between Hobart, Macquarie Island, and Davis Station.
• Establishing baseline environmental measurements for the Antarctic region during the austral winter-spring transition of 1995.

Strengths

• Data logged at a high 20-second sampling interval.
• Temporal coverage spans approximately three months from August to October 1995.

Limitations

• Dataset is from a single, limited-research resupply cruise, reducing scientific scope.
• Data is over 28 years old, potentially limiting relevance for contemporary climate models.
• Specific column names, data volume, and completeness metrics are unknown.
