Cenozoic Glacial History of the Lambert Graben-Prydz Bay Region, East Antarctica

Geoscience Australia Data provides a review of the Cenozoic stratigraphy and glacial history of the Lambert Graben-Prydz Bay region in East Antarctica. The glacigene strata record at least 10 intervals of glacial advance and more than 17 intervals of glacial retreat. This review presents a partial reconstruction of glacial extent that can be compared to eustatic sea-level records.

Use Cases

• Correlating glacial advance/retreat cycles with Milankovitch climate frequencies based on the described stratigraphic intervals.
• Modeling past marine incursions based on the description of marine conditions reaching over 450 km inland during extreme retreats.
• Reconstructing continental shelf progradation events based on the link between large Lambert Glacier advances and shelf edge changes.
• Comparing Antarctic glacial extent with eustatic sea-level records from other regions, as suggested by the review's purpose.

Strengths

• Identifies at least 10 specific intervals of glacial advance and more than 17 intervals of glacial retreat.
• Describes a spatial reconstruction of marine conditions extending over 450 km inland from the modern ice shelf edge.
• Provides a review intended for comparison with external eustatic sea-level records.

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.
