Real-time sea water velocity data measured by a HF ocean radar system covering the Rottnest Shelf and Perth Canyon region in Western Australia. The Australian Ocean Data Network provides this data, which also supports calculations of wind direction and significant wave height. The dataset was last updated on 2026-05-06.
Use Cases
- Modeling the Leeuwin Current dynamics and its wake effect based on surface current measurements.
- Studying whale and fish aggregations in the Perth Canyon based on physical oceanographic process data.
- Monitoring the influence of Swan River outflow and submarine groundwater discharges based on coastal current patterns.
- Analyzing topographically induced upwelling and associated productivity based on real-time velocity data.
Strengths
- Radar system operates at a specific frequency of 8.512 MHz with a bandwidth of 33 KHz.
- Provides a maximum measurement range of 200 Km.
- Data is collected from two specific receive array locations: Fremantle (32.031 S, 115.746 E) and Guilderton (31.342 S, 115.489 E).
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 coastal region monitored.
