Late Neogene Ice Drainage Changes in Prydz Bay, East Antarctica

The dataset describes changes in the Lambert Glacier-Amery Ice Shelf drainage system in Prydz Bay during the late Neogene. It includes information on ice flow patterns, debris flow deposits, and compositional changes around 1.1 million years before present. The data was provided by Geoscience Australia and was last updated in March 2026.

Use Cases

• Modeling ice sheet dynamics based on described changes in flow patterns and ice discharge.
• Analyzing sediment composition shifts for paleoenvironmental reconstruction based on debris flow deposits.
• Correlating extreme ice advance events with climatic cycles based on the described stratigraphy and age control.

Strengths

• Focuses on a specific, well-described geological system (Lambert Glacier-Amery Ice Shelf in Prydz Bay).
• Includes temporal markers such as the Early Pliocene and the 1.1 Ma BP compositional change.
• References stratigraphy from an Ocean Drilling Program hole for age control.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
