This dataset contains the underway data from Voyage 1 1993-94 (THIRST) of the Aurora Australis. This was a manned marine science voyage. DLS data types were logged at 10-second intervals. The observations were taken between August and October 1993 en route from Hobart to Macquarie Island to Heard Island and back to Hobart.

XBT data were obtained on the legs to and from Hobart. CTD data were collected around Heard Island.

The data have been acquired at 0.1 Hz. There will be the occasional invalid value such as temperatures being out of range. This dataset has not been checked. Please verify the data before use.

Where data for a particular sensor do not exist for a particular time, the last known value is used unless the sensor has been disabled or has encountered an error. For example, some sensors only record data every minute, but the resolution for the underway dataset is 10 seconds, so the same value will be used 6 times a minute. No averages are taken for sensors that capture data at a rate other than every 10 seconds. Instead, each record will be a snapshot of each sensor at that time.
Data are available on-line via the AADC web page.
