BANGSS: Antarctic Marine Geology and Seismic Survey, 1994/95

Prydz Bay, the Mac.Robertson Shelf, and the Kerguelen Plateau were surveyed during the 1994/95 AGSO Cruise 149 (BANGSS). The cruise aimed to understand modern sedimentary processes and the Plio-Pleistocene environmental history of the Antarctic margin. It was conducted by the Australian Ocean Data Network and the Antarctic Co-operative Research Centre.

Use Cases

• Reconstructing ice sheet fluctuations based on sediment records from Prydz Bay.
• Studying post-glacial environmental change using thick Holocene sediments from the Mac.Robertson Shelf basins.
• Analyzing variations in the Polar Front and water masses from sedimentary sequences on the Kerguelen Plateau.
• Investigating the tectonic and stratigraphic development of the Antarctic margin using seismic lines.

Strengths

• Targets three distinct geological features: Prydz Bay fan deposits, Mac.Robertson Shelf basins, and the Kerguelen Plateau.
• Explicitly aims to provide environmental records for three key time intervals: 0-10,000, 0-160,000, and 0-5,000,000 years.

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 bias inherent to the specific cruise track.
