AGSO Cruise 186: Antarctic Marine Geoscience Survey of Vincennes and Prydz Bays, 1996/97

East Antarctic marine geoscience data from the 1996/97 AGSO/ANARE voyage to Vincennes Bay, Prydz Bay, and the Mac.Robertson Shelf. The dataset includes preliminary results from sediment cores, seismic surveys, and sidescan sonar data collected to study ice sheet retreat and paleoenvironmental records. It was published by Geoscience Australia and last updated in April 2026.

Use Cases

• Modeling post-Last Glacial Maximum ice sheet retreat based on core and seismic data from shelf basins.
• Correlating Holocene diatom and organic carbon records with ice core data from Law Dome.
• Analyzing sedimentary facies and processes in glacial troughs and moraines based on core descriptions and sidescan sonar records.
• Supporting site survey planning for Ocean Drilling Program (ODP) proposals with seismic data from the Prydz Bay fan.

Strengths

• Includes data from multiple key Antarctic regions: Vincennes Bay, Prydz Bay, and the Mac.Robertson Shelf.
• Describes collection of 27 sediment cores and over 1,100 km of seismic and sidescan sonar data.
• Identifies a traceable 'interstadial' sediment unit across more than 15,000 km² of the Prydz Channel.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Primary data files are in PDF/HTML report formats, which may require extraction for analysis.
