Antarctic Ice-Sheet Dynamics Model for Prydz Bay Region, Post-Oligocene

Ice-sheet numerical modeling reveals topographic controls on changes in ice-sheet extent and dynamics in the Lambert-Amery system at Prydz Bay, East Antarctica. The dataset, hosted by the Australian Ocean Data Network, was last updated on 2026-04-10. It focuses on the evolution from ice-cliff to ice-stream dynamics and the associated sedimentation history from the Miocene to the Pleistocene.

Use Cases

• Modeling ice-sheet extent and flow based on bed morphology and bathymetry.
• Analyzing the correlation between bathymetric volume changes and fan sedimentation history.
• Investigating the negative feedback between erosion and glaciation in an overdeepened graben.
• Studying the combined impact of erosional history and mountain uplift on ice-sheet evolution.

Strengths

• Focuses on the largest and oldest outlet of the East Antarctic Ice Sheet.
• Modeling results link topography, bathymetry, and sedimentation history.

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/temporal bias inherent to data_gov_au.
