Bonney Coast HF Ocean Radar Sea Water Velocity Data

Two SeaSonde HF ocean radar stations at Nora Creina and Blackfellows Cave measured surface currents along the Bonney Coast, South Australia. The system operated at 5.211 MHz with a 200 km maximum range and 3 km resolution. This site was decommissioned in March 2017.

Use Cases

• Modeling coastal upwelling dynamics based on recurring annual feature described.
• Analyzing larval species transport based on relationships between ocean circulation and ecosystems.
• Studying ocean processes on weekly to El Nino time scales based on linking observations mentioned.
• Mapping surface current velocity fields based on HF radar coverage area.

Strengths

• Data from two specific radar stations with precise coordinates (37.329 S 139.850 E and 37.940 S 140.457 E).
• System specifications are detailed: 5.211 MHz frequency, 50 KHz bandwidth, 200 km max range, 3 km range resolution.
• Covers a region with a significant, recurring annual upwelling feature that changes the ecosystem.

Limitations

• Dataset was decommissioned in March 2017, limiting temporal coverage to before that date.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
