Australian Ocean Data Network hosts 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, with marine conditions reaching over 450 km inland during extreme retreats. This partial reconstruction can be compared to eustatic sea-level records from the southern Australian continental margin.
Use Cases
- Reconstructing glacial extent timelines based on recorded intervals of advance and retreat.
- Comparing Antarctic glacial cycles with eustatic sea-level records from other regions.
- Analyzing continental shelf progradation events linked to large advances of the Lambert Glacier.
- Modeling paleo-marine environments based on evidence of open marine deposition during retreats.
Strengths
- Identifies at least 10 intervals of glacial advance and more than 17 intervals of glacial retreat.
- Describes marine conditions extending over 450 km inland from the modern ice shelf edge.
- Provides a reconstruction 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.
