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 Voyage 5 1996-97 (BRAD) of the Aurora Australis. This was a manned marine science cruise. The main project was to conduct seismic, benthic and geological survey of Vincennes Bay, MacRobertson Shelf, Nilsen Basin, Iceberg Alley and Prydz Bay. Marine Science Support Data Quality and Engineer's Reports are available via the Related URL section.
CTD data were also obtained. Bottom photos were taken at 10 of the CTD sites; digitized images of these bottom photos are stored on the marine science server: /BIGBIRD/marscisup/Data/Images/969705/.

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. A "supplementary" dataset is also available for download from the provided URL. It contains raw data collected directly from the ship, which has not been quality checked.
