All scientific data collected by the Australian Antarctic program (AAp) are eventually described in the Catalogue of Australian Antarctic and Subantarctic Metadata (CAASM). CAASM can be used to search through AAp data descriptions, and it also provides links to access publicly available datasets, which can either be immediately downloaded or obtained from the Australian Antarctic Data Centre (AADC).
This dataset contains the underway data from the Aurora Australis Voyage 4 (SEXY) 1997-98. This voyage was a part resupply/changeover, part seal survey cruise, which visited Casey, Davis, Mawson and Macquarie Island. Underway (meteorological, fluorometer, thermosalinograph and bathymetry) data are available online via the Australian Antarctic Division Data Centre web page (see URL given below). Documentation on data quality and instrumentation are available via the Related URL section.
The following scientific objectives for the voyage were listed in the Voyage Leader's Report:
1) Undertake the seal survey marine science program between Casey and Davis.
2) Transfer summer science personnel to Beaver Lake in support of the Prince Charles Mountain Program from Sansom Island.

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.

Reports from the voyage are also available for download.
