Antarctic Ice Sheet Dynamics and Topography Model for Prydz Bay Region

Ice-sheet numerical modeling reveals bed morphology likely drove changes in ice-sheet extent and dynamics in the Lambert-Amery system at Prydz Bay. The dataset, hosted by the Australian Ocean Data Network, focuses on topographic controls on ice dynamics from the Oligocene to the Pleistocene. It was last updated on 2026-06-27.

Use Cases

• Modeling ice-sheet response to bed morphology based on the described topographic and bathymetric controls
• Reconstructing sedimentation history based on the correlation between bathymetric volume and fan sedimentation
• Analyzing feedback between erosion and glaciation based on the described overdeepening of the graben

Strengths

• Focuses on the Lambert-Amery system, the largest and oldest outlet of the East Antarctic Ice Sheet
• Analysis spans from the Oligocene Epoch to the Pleistocene, covering a significant geological timeframe
• Integrates geological data with numerical ice-sheet modeling

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 on Prydz Bay
