Lithostratigraphy, grain sizes, and down-hole logs from Ocean Drilling Program Sites 1166 and 1167 reconstruct glacial processes in eastern Prydz Bay, Antarctica. The Australian Ocean Data Network hosts this dataset, which was last updated in May 2026. Sediment analysis indicates repeated advances and retreats of the Lambert Glacier-Amery Ice Shelf system from the upper Pliocene to mid Pleistocene.
Use Cases
- Reconstruct glacial advance-retreat cycles based on interbedded sediment facies described.
- Analyze the link between glacial drainage systems and Southern Ocean ice-rafted debris delivery based on the described record.
- Study the transition from open-marine to subglacial conditions based on the described lithostratigraphic sequence.
- Model trough-mouth fan development based on described coarse-grained debrites and bottom-current deposits.
Strengths
- Analysis spans two distinct locations: Site 1166 on the continental shelf and Site 1167 on the upper slope.
- The record provides a temporal focus on the upper Pliocene-lower Pleistocene transition and extends to 0.78 Ma.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data may reflect geographic bias inherent to data_gov_au, focusing solely on Prydz Bay.
