Description

This dataset contains the underway data from Voyage 1 and 1.1 1991-92 (WOCE91) of the Aurora Australis. This was a marine science voyage, being the first WOCE SR3 transect from Tasmania to Dibble Ice Tongue and return. Voyage 1 went to Macquarie Island but returned with a broken winch. The program then resumed as Voyage 1.1. See the Marine Science Support Data Quality and Programmer's Reports via the Related URL section.

The broad aims of the voyage were two-fold. The first was the delivery of personnel and cargo to Macquarie Island to conduct mainly summer scientific programs, all aspects of this program being achieved. The second was to conduct a marine scientific research program whose primary goal was to carry out the first of seven occupations of oceanographic transect SR3 of the international World Ocean Circulation Experiment (WOCE) planned for the next five years, but which also involved a number of piggy-back programs.

The scientific program on Voyage 1 was severely threatened by the failure of the CTD winch at the beginning of the voyage. The winch failure and subsequent repairs, described in detail elsewhere in the report, led to a loss of five days of science time from the voyage, about a third of the total science time available. Such a large loss of time inevitably compromised the scientific program on the voyage.

Quality

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.
