Bonney Coast HF Ocean Radar Sea Water Velocity Data (Decommissioned 2017)

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 maximum range of 200 km and a range resolution of 3 km. This site was decommissioned in March 2017.

Use Cases

• Modeling coastal upwelling dynamics based on the recurring annual feature described.
• Studying larval species transport based on the relationship between ocean circulation and ecosystems mentioned.
• Analyzing ocean processes on weekly to El Nino time scales based on the linking observations described.
• Mapping surface current velocity fields within the 200 km radar coverage area.

Strengths

• Data originates from two specific radar stations with precise locations (37.329 S 139.850 E and 37.940 S 140.457 E).
• System specifications are detailed, including a 5.211 MHz frequency, 50 KHz bandwidth, and 3 km range resolution.
• Covers a significant coastal area with a recurring annual upwelling feature important for ecosystem studies.

Limitations

• The site was decommissioned in March 2017, limiting data to a historical period.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
