AGSO Cruise 149 Report: Antarctic Sediment and Climate Study, 1995

A 1995 research cruise report details a marine geoscience program targeting Prydz Bay and the Kerguelen Plateau to understand Antarctic climate history. The program aimed to study sedimentary records spanning up to 5 million years to model ice sheet and ocean circulation changes. Geoscience Australia Data published this pre-cruise report outlining scientific goals and methods.

Use Cases

• Modeling past Antarctic ice sheet fluctuations based on sediment records from the Lambert Glacier outlet.
• Reconstructing Southern Ocean water mass history based on sedimentary sequences from the Kerguelen Plateau.
• Analyzing Plio-Pleistocene environmental changes based on core samples targeting 0-5 million year intervals.
• Studying modern sedimentary processes on the Antarctic margin based on trough-mouth fan and basin sampling.

Strengths

• Report outlines specific scientific goals for three time intervals: 0-10,000, 0-160,000, and 0-5,000,000 years.
• Targets three distinct geographical features: Prydz Bay trough-mouth fans, MacRobertson Shelf basins, and Kerguelen Plateau basins.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
