AGSO Cruise 149 Report: Antarctic Sediment Sampling for Paleoclimate Study, 1995

February-April 1995 cruise report from the R.V. Aurora Australis detailing a marine geoscience program in Prydz Bay and the Kerguelen Plateau. The report outlines aims and methods for studying sedimentary processes and Plio-Pleistocene environmental history to understand Antarctic ice sheet and Southern Ocean circulation changes. It was published by Geoscience Australia Data.

Use Cases

• Modeling Antarctic ice sheet behavior during past climatic fluctuations based on sediment records from Prydz Bay.
• Studying Southern Ocean water mass reorganization during the Quaternary period based on samples from the Kerguelen Plateau.
• Reconstructing paleoenvironments over the last 5 million years based on the described Plio-Pleistocene sediment analysis goals.

Strengths

• Report details a specific scientific cruise (AGSO Cruise 149) with a clear temporal scope (February-April 1995).
• Describes three distinct geographical study targets: trough-mouth fan deposits, sediment traps, and depositional basins.
• Explicitly links data collection goals to three defined paleoclimate time intervals (0-10k, 0-160k, and 0-5 million years).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The primary files are PDF and HTML reports, not structured data tables.
