Aurora Australis Underway Ocean Data from 1991-92 WOCE Voyage

Aurora Australis Voyage 1 and 1.1 (WOCE91) underway data captures continuous ship-based measurements from a 1991-92 marine science expedition. The voyage conducted the first WOCE SR3 transect from Tasmania to the Dibble Ice Tongue in Antarctica. Data was collected by the Australian Antarctic Data Centre (AU_AADC) and published in October 1991.

Use Cases

• Analyzing continuous underway measurements like sea surface temperature and salinity along the SR3 transect.
• Studying temporal and geospatial patterns of oceanographic parameters recorded during the voyage.
• Validating ocean circulation models using in-situ data from the WOCE program's Southern Ocean survey.
• Investigating water mass properties and frontal structures between Tasmania and the Antarctic coast.

Strengths

• Data from the first World Ocean Circulation Experiment (WOCE) SR3 transect.
• Continuous underway measurements provide a spatial time-series along the voyage track.

Limitations

• Specific parameters, row counts, and file formats are unknown.
• Data is from a single 1991-92 voyage, limiting temporal scope.
• A known equipment issue (broken winch) interrupted the initial Voyage 1.
