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

A 1994/95 research cruise collected marine geoscience data from Prydz Bay, the Mac.Robertson Shelf, and the Kerguelen Plateau. The program, designated AGSO survey 149, aimed to understand modern sedimentary processes and the Plio-Pleistocene environmental history of the Antarctic margin. The data likely includes seismic lines and sediment samples to study ice sheet fluctuations and Southern Ocean water mass changes.

Use Cases

• Reconstructing ice sheet fluctuations based on sediment records from Prydz Bay mentioned in the description.
• 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 collected during the cruise.

Strengths

• Data targets three distinct geological features (trough-mouth fans, shelf basins, plateau sediments) for focused analysis.
• Research goals are explicitly defined for three key time intervals: 0-10k, 0-160k, and 0-5 million years.
• Cruise is part of a formal program (AGSO/Antarctic CRC/ANARE) with a designated survey number (149).

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 quantitative analysis.
