Description

This dataset contains the underway data from Voyage 6 1991-92 (FISHOG) of the Aurora Australis. Marine science was carried out in the vicinity of Heard Island. Mawson, Davis and Casey were also visited. Data and the Marine Science Support Data Quality Report can be obtained via the links at the Related URL section.

Also provided are scans of two printed plots of sections of the Voyage 6 1991/92 (FISHOG) track:
(i) the section of the track in the Heard Island area, 22 January to 13 February 1992; and
(ii) transects north of the Antarctic coastline between 66 degrees East and 82 degrees East, 18 February to 6 March 1992.

From the Voyage Leader's Report

Voyage 6 was the main marine science cruise of the season for Aurora Australis. Research was conducted in the regions of Heard Island and Prydz Bay, and the main objectives (based on proposals approved by AREG) were:

1) The second phase of the study of distribution, abundance and ecology of the important fish species on the Kerguelen Plateau adjacent to Heard Island.
2) Sample zooplankton at discrete depth strata in the vicinity of Heard Island.
3) Collect data on the taxonomy and biology of Anrtarctic cephalopods (squid and octopus), and other benthic organisms brought up in the fish trawls.
4) Collect oceanographic data from the Heard Island area.
5) Complete a CTD section from the abyssal plain to the summit of the southern Kerguelen Plateau to establish whether or not a western boundary current exists.
6) Complete an oceanographic survey of the Prydz Bay area.
7) Deploy and retrieve a mooring array containing sediment traps and other instrumentation in Prydz Bay.
8) A hydro-acoustic survey to determine the distribution and abundance of Antarctic krill.
9) Measurement of the amount of carbon dioxide in sea water and air.
10) Measurement of the amount of dimethyl sulphide in seawater.
11) Conduct experiments on the biochemistry and physiology of freshly caught live krill, and to bring live krill back to the laboratoris in Kingston for further experiments.
12) Make observations of seabirds at sea.
13) Conduct iceberg observations in accordance with instructions from Glaciology Section.

In addition to scientific programmes, the deployment of four wintering personnel and minimum equipment at Spit Bay, Heard Island by rubber boat was planned, as well as visits to Mawson and Davis near the end of the voyage to RTA personnel, equipment and rubbish.

Quality

See the Marine Science Support Data Quality Report 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.
