AGSO Cruise 149 Report: Antarctic Sediment and Climate 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, from the Australian Ocean Data Network, outlines aims to study modern sedimentary processes and Plio-Pleistocene environmental history to understand Antarctic ice sheet and Southern Ocean circulation changes. Goals include providing palaeoenvironmental statements for time intervals from 0-10,000 years up to 0-5,000,000 years.

Use Cases

• Modeling past Antarctic ice sheet behavior based on the sedimentary record from the Lambert Glacier-Amery Ice shelf outflow.
• Reconstructing Southern Ocean water mass and polar front variations during glacial cycles using sediment sequences from the Kerguelen Plateau.
• Studying Plio-Pleistocene environmental history from sediment trap and fan deposits in Prydz Bay and the Mac. Robertson Shelf.

Strengths

• Report details a targeted scientific cruise with specific geographical features: trough-mouth fan deposits, shelf-basin sediment traps, and Kerguelen Plateau basins.
• Explicitly defines three key paleoenvironmental time intervals for study: 0-10,000 years, 0-160,000 years, and 0-5,000,000 years.

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.
