Description

This dataset contains the underway data from Voyage 7 1992-93 (KROCK) of the Aurora Australis. This was a manned marine science voyage. The observations were taken between January and March 1993 on route from Hobart to Davis to Mawson to Casey and back to Hobart. DLS and NoQalms data types were logged. See the Marine Science Support Data Quality and Programmer's Reports at the Related_URL section.

Also available is a scan of a printed plot of a section of the Voyage 7 1992/93 (KROCK) track:
transects north of the Antarctic coastline between 60 degrees East and 83 degrees East, 15 January to 7 February 1993.

From the voyage leader's report:

The principal purpose of the voyage was to carry out marine science research in the Prydz Bay region in two phases:

1) A biological phase of 22 days, dominated by research into the distribution, abundance and biology of krill, zooplankton and fish,
2) A geological phase of 10 days to study the sedimentary history of the region.

A number of secondary programs involved the study of; krill chemistry, water chemistry distribution, abundance and description of benthos, distribution and abundance of birds, and distribution of icebergs.

After completion of the marine science program, RTA expeditioners and cargo were to be collected at Davis and Mawson, some cargo was transferred from Davis to Mawson. During the course of the voyage, Casey RTA expeditioners and cargo were added, giving a full expeditioner complement of 109 on the return journey to Hobart.

Quality

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 or via the Related URL section below. 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.
