Geoscience Australia Data provides a study on the palaeogeography of the Bass Strait land-bridge, a key zone of human and biological connectivity. The analysis utilizes high-resolution bathymetry to model landscape change and shoreline transgression during sea-level rise after the Last Ice Age. The dataset was last updated on March 25, 2026.
Use Cases
- Modeling ancient human migration routes based on the description of the exposed land-bridge.
- Analyzing shoreline transgression rates based on the finding that rates could exceed 30 meters per year.
- Studying the impact of rapid sea-level rise on First Nations communities and Country based on the described life-span scale of change.
- Reconstructing palaeo-landscapes based on the use of high-resolution bathymetry data.
Strengths
- Based on high-resolution bathymetry data, as stated in the description.
- Provides a benchmark for understanding land-bridge flooding and human migration impact, as cited in the study.
- Associated with a peer-reviewed publication in Quaternary Science Reviews (2025).
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 the specific study region.
