Antarctic Sediment Cores and Bathymetry from Prydz Bay and Mac.Robertson Shelf, 1993

The Australian Ocean Data Network hosts a cruise preview report for Voyage 7 of the 1992/93 Antarctic Division shipping season. The dataset likely contains information on sediment cores, grab samples, and 3.5kHz echo sounder data collected from Prydz Bay and the Mac.Robertson Shelf in Antarctica during January-March 1993. The data was gathered by the R.V. Aurora Australis as part of the Co-operative Research Centre for Antarctic and Southern Ocean Environments' research program.

Use Cases

• Calibrating climatic models based on past environmental records contained in sediment cores.
• Studying sedimentation processes and past glacier behavior on the Antarctic shelf and slope.
• Inferring the extent of post-glaciation iceberg gouging based on bathymetry and echo sounder data.
• Identifying sediment accumulation sites suitable for coring from 3.5 kHz records.

Strengths

• Focuses on a specific, scientifically important region: the Lambert Glacier-Amery Ice Shelf system, the largest ice stream draining East Antarctica.
• Includes multiple data collection methods: gravity cores, grab samples, and 3.5kHz echo sounder data.
• Targets a clear temporal period: the Late Quaternary history.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic/temporal bias inherent to data_gov_au.
