Aurora Australis 1994-95 Underway Oceanographic Observations

Aurora Australis Voyage 3 (MIRTH) 1994-95 Underway Data contains oceanographic measurements logged at 20-second intervals during a December 1994 resupply and training voyage. The data was collected by the Australian Antarctic Data Centre (AU_AADC) en route from Hobart to Macquarie Island and back. Observations were finalized on December 10, 1994.

Use Cases

• Analyze temporal patterns in oceanographic variables like sea surface temperature or salinity from the 20-second interval time-series data.
• Correlate underway sensor readings with the ship's voyage track between Hobart and Macquarie Island for spatial analysis.
• Use the logged parameters for validating or calibrating regional oceanographic models of the Southern Ocean.
• Study short-term variability in marine conditions during the Antarctic summer period of December 1994.

Strengths

• Data logged at a high temporal resolution of 20-second intervals.
• Includes specific voyage context as a marine science training cruise, suggesting structured data collection.
• Associated Programmer's and Data Quality Reports are available for reference.

Limitations

• The exact number of data rows, columns, and specific measured parameters are unknown.
• Data is temporally limited to a single voyage in December 1994.
• Geographic coverage is restricted to the transit path between Hobart and Macquarie Island.
