Description

This dataset contains the underway data from Voyage 6 1994-95 (BANGSS) of the Aurora Australis. This was a marine science voyage. The observations were taken between February and April 1995. DLS and NoQalms data types were logged at 10-second intervals. See the Voyage Leader's, Marine Science Support Data Quality, Programmer's and Engineer's Reports via the Related URL section.

XBT and CTD data were also obtained during this voyage.

From the Voyage Leader's Report:

We departed Hobart at 19:40, 6 February 1995. We set sail for the first way point at 62 S, 110 E. Then headed west with the object of conducting east-west tie lines across the Trough Mouth Fan and Mac.Robertson Shelf programs. Problems with the firing mechanism for the airgun caused this program to be altered on an ad hoc basis. We achieved the western north-south line of the Trough Mouth Fan program during the night of 19-20 February and passed Fram Bank on the 20th. Commenced east-west tie line of the Mac.Robertson Shelf program on 20th, but had to cease that before its western end at 1100 local on 21st to make Mawson by 1500 local. The line gathered excellent data, but had a couple of gaps where the equipment was pulled in to avoid ice damage. This line was the first that employed the sidescan sonar.

See the report for more information on seismic programs, bathymetric data, CTDs, cores, current meters, iceberg observations, krill collection, etc.

Quality

Please see the Marine Science Support Data Quality Report via the Related URL section.

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 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.

Reports from the voyage are also available for download.
