High-resolution bathymetry data models landscape change during the flooding of the Bass Strait land-bridge after the Last Ice Age. The analysis finds shoreline transgression rates exceeding 30 meters per year, which would have drowned 15 km of land within a human lifetime. This dataset provides a benchmark for understanding land-bridge flooding and its impact on human migrations in southeastern Australia.
Use Cases
- Model paleo-landscapes and human migration routes based on high-resolution bathymetry.
- Analyze the impact of rapid sea-level rise on coastal populations based on transgression rates.
- Benchmark land-bridge flooding events based on the provided analysis framework.
- Study human connectivity and clan estate use based on the exposed Bass Strait land-bridge.
Strengths
- Analysis is based on high-resolution bathymetry data.
- Quantifies shoreline transgression rates exceeding 30 meters per year.
- Provides a benchmark for understanding land-bridge flooding.
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.
