Post-Oligocene to Pleistocene model results investigating topographic controls on ice-sheet dynamics in the Lambert-Amery system at Prydz Bay, East Antarctica. The dataset, hosted by the Australian Ocean Data Network, was last updated on 2026-06-04. It uses numerical modeling to show how bed morphology, graben erosion, and surrounding mountain uplift influenced ice-sheet extent and flow.
Use Cases
- Validate ice-sheet numerical models based on inferred changes from ice-cliff to ice-stream dynamics.
- Study feedback mechanisms between erosion and glaciation based on bathymetric volume changes.
- Correlate ice-sheet flow history with Prydz Channel fan sedimentation records.
- Analyze the role of graben overdeepening in preventing shelf-edge glaciation under Last Glacial Maximum-like conditions.
Strengths
- Focuses on a specific, significant outlet of the East Antarctic Ice Sheet (the Lambert-Amery system).
- Integrates geological data interpretation with numerical modeling results.
- Analysis spans a long temporal range from the Oligocene to the Pleistocene.
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.
