AGSO Cruise 149 (BANGSS): Antarctic Marine Geology Survey Results, 1994/95

The 1994/95 AGSO Cruise 149 (BANGSS) collected marine geoscience data from Prydz Bay, Mac.Robertson Shelf, and the Kerguelen Plateau. The Australian Ocean Data Network hosts a summary report of preliminary results aimed at understanding sedimentary processes and Quaternary climate change. The cruise targeted trough-mouth fan deposits, shelf-basin sediment traps, and plateau sediments to reconstruct environmental history.

Use Cases

• Reconstructing ice sheet fluctuations based on sediment records from Prydz Bay downstream of the Lambert Glacier.
• Analyzing post-glacial environmental change based on thick Holocene sediments in deep basins on the Mac.Robertson Shelf.
• Studying Southern Ocean water mass reorganization during Quaternary climate episodes based on sedimentary sequences from the Kerguelen Plateau.
• Investigating modern sedimentary processes and organism contributions to aid interpretation of ancient Antarctic sedimentary records.

Strengths

• Focuses on three distinct Antarctic features (Prydz Bay, Mac.Robertson Shelf, Kerguelen Plateau) for comparative analysis.
• Explicitly targets paleoenvironmental records over three key time intervals: 0-10,000 years, 0-160,000 years, and 0-5,000,000 years.
• Data originates from a coordinated research program involving AGSO, Antarctic CRC, and ANARE.

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.
