CORL HF Ocean Radar: Sea Water Velocity Off Western Australia

Delayed-mode sea water velocity data from the Coral Coast HF ocean radar system covering an area of the Western Australia Coast. The system consists of two SeaSonde stations at Dongara and Green Head, operating at 4.463 MHz with a maximum range of 200 km. It is provided by the Australian Ocean Data Network, with metadata last updated in July 2026.

Use Cases

• Modeling larval species transport based on measured surface currents.
• Analyzing the coupling of the Leeuwin Current with coastal winds, tides, and waves.
• Monitoring the shelf from Fremantle to Geraldton based on continuous radar coverage.
• Studying eddy generation and its impact on higher marine species and ecosystems.

Strengths

• System operates at a frequency of 4.463 MHz with a bandwidth of 25 KHz.
• Provides a maximum range of 200 Km and a range resolution of 6 Km.
• Offers continuous monitoring in conjunction with the TURQ and ROT radar systems.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Freshness should be verified as the last update is dated July 2026.
