Bass Strait Palaeogeography and Shoreline Transgression During Sea-Level Rise

Bass Strait, separating Tasmania from mainland Australia, is analyzed for its role as a land-bridge during the Last Ice Age. The dataset likely contains high-resolution bathymetry used to model landscape change and shoreline transgression rates exceeding 30 meters per year. This analysis provides a benchmark for understanding land-bridge flooding and its impact on human migrations, as published in Quaternary Science Reviews in 2025.

Use Cases

• Modeling past human migration routes based on the reconstructed palaeogeography of the exposed Bass Strait land-bridge.
• Analyzing rates of shoreline transgression and land loss during post-glacial sea-level rise.
• Studying the impact of rapid environmental change (within a human lifetime) on First Peoples' residence and travel across Country.

Strengths

• Based on high-resolution bathymetry data.
• Provides analysis of shoreline transgression rates exceeding 30 meters per year.
• Benchmark study published in a peer-reviewed journal (Quaternary Science Reviews, 2025).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset scale are unknown, which may limit suitability assessment.
• Data format is listed as HTML, which may not be a standard structured data format.
