Lithostratigraphy, grain sizes, and down-hole logs from two Ocean Drilling Program sites reconstruct glacial processes in eastern Prydz Bay. The record indicates repeated advances and retreats of the Lambert Glacier-Amery Ice Shelf system from the Pliocene to Pleistocene. Data from the Australian Ocean Data Network shows the grounding line did not extend to the shelf break after 0.78 Ma.
Use Cases
- Reconstruct glacial advance/retreat cycles based on lithofacies fluctuations
- Analyze links between trough-mouth fan development and Southern Ocean ice-rafted debris
- Model ice stream dynamics in the Prydz Channel using down-hole log data
- Study the transition from glaciomarine sediments to subglacial tills
Strengths
- Analysis of two distinct sites (1166 on continental shelf, 1167 on upper slope) provides comparative context
- Description includes specific temporal markers like the 0.78 Ma grounding line shift
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
