Bass Strait Land-Bridge Palaeogeography and Shoreline Transgression Rates

High-resolution bathymetry data used to model landscape change during the flooding of the Bass Strait land-bridge after the Last Ice Age. The analysis, published in Quaternary Science Reviews in 2025, finds shoreline transgression rates exceeding 30 meters per year. This dataset provides a benchmark for understanding land-bridge flooding and its impact on human migrations in southeastern Australia.

Use Cases

• Modeling past sea-level rise impacts based on high-resolution bathymetry data
• Analyzing human migration routes based on the exposure and flooding timeline of the land-bridge
• Estimating rates of shoreline transgression based on calculated metrics exceeding 30 meters per year
• Studying the connection between climate cooling events and human movement based on the described timing of first crossings

Strengths

• Analysis is based on high-resolution bathymetry data
• Published in a peer-reviewed journal (Quaternary Science Reviews, 2025)
• Provides specific transgression rate metrics (exceeding 30 m/yr)

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
