High-resolution bathymetry data underpins a study of landscape change during sea-level rise in the Bass Strait region. The analysis finds shoreline transgression rates exceeding 30 m/yr, indicating 15 km of land could drown within a human lifetime. This dataset provides a benchmark for understanding land-bridge flooding and its impact on human migrations.
Use Cases
- Modeling shoreline transgression rates based on high-resolution bathymetry.
- Analyzing the impact of rapid sea-level rise on human habitation and movement.
- Reconstructing palaeogeography of the Bass Strait land-bridge for archaeological context.
- Benchmarking land-bridge flooding events against other global examples.
Strengths
- Based on high-resolution bathymetry data.
- Provides specific rates of shoreline transgression (exceeding 30 m/yr).
- Quantifies potential land loss (15 km) within a human lifetime.
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.
