High-resolution bathymetry data was used to model landscape change during sea-level rise in the Bass Strait region. The analysis finds shoreline transgression rates exceeding 30 meters per year, indicating 15 kilometers of land would drown within a human lifetime. This dataset, published in Quaternary Science Reviews in 2025, provides a benchmark for understanding land-bridge flooding and its impact on human migrations.
Use Cases
- Model shoreline transgression rates based on high-resolution bathymetry data mentioned in the description
- Analyze the impact of rapid landscape drowning on human mobility and residency patterns
- Benchmark land-bridge flooding events for comparative studies of other regions
- Study the timing of human crossings relative to land-bridge exposure during climate cooling events
Strengths
- Analysis based on high-resolution bathymetry data
- Quantifies shoreline transgression rates exceeding 30 meters per year
- Provides a benchmark for understanding land-bridge flooding impacts
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
