October to November 1993 underway data from the Aurora Australis's Voyage 2. The dataset contains NoQalms data types logged at 60-second intervals during a non-marine science transit from Hobart to Mawson to Davis and back to Hobart. It was collected by the Australian Antarctic Data Centre (AU_AADC).
Use Cases
- Analyzing temporal patterns in NoQalms sensor readings (e.g., temperature, salinity) across the 60-second interval time series.
- Correlating underway data features (like logged NoQalms types) with the ship's route between Hobart, Mawson, and Davis stations.
- Establishing baseline environmental conditions for the Southern Ocean during the Austral spring of 1993 using the continuous sensor logs.
Strengths
- Data logged at a high temporal resolution of 60-second intervals.
- Covers a specific voyage period from October to November 1993.
- Documents a complete transit route between key Antarctic and Tasmanian stations.
Limitations
- The exact number of data rows, columns, and specific measured variables (besides 'NoQalms data types') is unknown.
- Dataset is from a single, non-science-focused voyage, which may limit the scope or consistency of measurements.
- Data is temporally stale, last updated in November 1993, with no indication of ongoing collection.
