Australian continental shelf data predicts where sediment is mobilized by tidal currents and swell waves. Estimates of significant wave height, period, and tidal current speed over a semi-lunar cycle were used to model threshold exceedance. The dataset was contributed by the Australian Ocean Data Network and was last updated in June 2026.
Use Cases
- Modeling seabed erosion and deposition patterns based on predicted sediment threshold exceedance.
- Assessing the relative importance of tidal currents versus swell waves for sediment entrainment.
- Mapping areas of the continental shelf susceptible to sediment mobilization for environmental impact studies.
- Calibrating hydrodynamic and sediment transport models using wave height, period, and current speed estimates.
Strengths
- Analysis covers the entire Australian continental shelf, providing a broad geographic scope.
- Examines sediment-entraining processes independently to quantify their relative importance.
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.
