Prydz Channel Fan and Extreme Ice Advance History in Prydz Bay

Late Neogene to mid Pleistocene stratigraphy of the Prydz Bay trough mouth fan, derived from ODP Site 1167. The dataset describes debris flow deposits and mudstone horizons indicating the history of the Lambert Glacier-Amery Ice Shelf system. It is hosted by the Australian Ocean Data Network and was last updated on 2026-04-28.

Use Cases

• Modeling past extreme ice advances based on debris flow deposit stratigraphy.
• Analyzing the cessation of major ice advances in the mid Pleistocene based on the described age control.
• Investigating the interaction of Milankovitch cycles and ice sheet response times as suggested in the description.
• Studying subglacial till deposition and debris flow processes in trough mouth fan formation.

Strengths

• Provides age control from ODP Site 1167, specifically referencing the Brunhes-Matuyama Boundary (780 ka).
• Describes a specific geological feature (the Prydz Bay trough mouth fan) with a clear stratigraphic interpretation.
• Last updated date is precisely recorded as 2026-04-28 15:46:59.662782.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is presented in HTML format, which may require extraction for structured analysis.
