Metadata details
198586010
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).

Description
This dataset contains bathymetry (water depth), ship's heading, ship's speed and position data collected during the Nella Dan Voyage 1 1985-86. This was a marine science voyage departing Hobart, visiting Heard Island, beset at Amundsen Bay and returning to Hobart. Data are available online via the Australian Antarctic Division Data Centre web page (or via the Related URL given below). For further information, see the Marine Science Support Voyage Report at the Related URL below.
Quality
See Marine Science Support Voyage Report at Related URL below.
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.
Access
Data are available online via the Australian Antarctic Division Data Centre 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. The supplementary dataset also contains a scanned copy of the acoustics log from the voyage.
