Description

This dataset contains the underway data from Voyage 4 1995-96 (BROKE) of the Aurora Australis. This was a manned marine science cruise. The major projects were a hydro-acoustic/trawl krill population survey, and the MARGINEX oceanographic survey on bottom water formation. CTD data were also obtained. The voyage also made stops at Davis and Macquarie Island.


The ship departed at 14:15 on the 19th of January, 1996, and returned to Hobart on the 31st of March, 1996. The scientific projects listed in the voyage leader's report were:

1) Hydroacoustic survey
2) Antarctic Margin Experiment (MARGINEX)
3) CTD data
4) Mooring data
5) Biology of phytoplankton, zooplankton and bacteria
6) Cetacean sighting survey
7) Passive acoustic whale survey
8) Bird observation program
9) Krill biology program
10) Fish physiology
11) Zooplankton physiology/behaviour

Quality

See the Marine Science Support Data Quality and Programmer's Reports at 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.
