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

AGSO Cruise 149 (BANGSS) summarizes preliminary results from a 1994/95 marine geoscience program in Prydz Bay, Mac.Robertson Shelf, and the Kerguelen Plateau. The program aimed to understand modern sedimentary processes and the Plio-Pleistocene environmental history of the Antarctic margin. It was conducted by the Australian Geological Survey Organisation (AGSO), the Antarctic Co-operative Research Centre, and the Australian National Antarctic Research Expeditions (ANARE).

Use Cases

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

Strengths

• Focuses on three distinct, scientifically targeted geological features: trough-mouth fan deposits, shelf-basin sediment traps, and plateau sediments.
• Explicitly designed to illuminate environmental history over three key time intervals: 0-10,000 years, 0-160,000 years, and 0-5,000,000 years.
• Data is associated with a specific, documented research cruise (AGSO survey 149, ANARE Voyage 6).

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
