Aurora Australis Voyage 1 Underway Oceanographic Measurements

Underway data was collected during the Aurora Australis Voyage 1 (ABSTAIN) marine science expedition between July and September 1995. Observations include DLS and NoQalms data types logged at 10-second intervals along the WOCE SR3 line and FORMEX square. The dataset is provided by the Australian Antarctic Data Centre (AU_AADC).

Use Cases

• Analyze temporal patterns in DLS and NoQalms measurements at 10-second resolution along the voyage track.
• Correlate underway sensor data with CTD and ADCP profiles taken during the Hobart to ice edge transect.
• Map spatial variability of ocean properties along the WOCE SR3 line and within the FORMEX square study area.
• Study seasonal conditions in the Southern Ocean during the austral winter period of July to September 1995.

Strengths

• High temporal resolution with data logged at 10-second intervals.
• Covers two defined study transects: the WOCE SR3 line and the FORMEX square.

Limitations

• Specific column names, data formats, and total row counts are unknown.
• Data is from a single voyage in 1995, limiting temporal analysis to a narrow period.
• Geographic coverage is restricted to the specific cruise track in the Southern Ocean.
