The Northwest Shelf (NWA) HF ocean radar system covers an area which includes the Ningaloo Peninsula and the Ningaloo Reef to the west. The Ningaloo Reef is one of the longest and most pristine reefs in the world. The reef is rich in marine biodiversity, with shark whales, turtles and fish aggregations, and high primary and secondary productions which are controlled by the physical oceanographic processes.
The NWA HF ocean radar is a WERA phased array system with 12-element receive arrays located at the Jurabi Turtle Centre (21.8068 S, 114.1015 E) and Point Billie (22.5432 S, 113.690 E). These radars operate at a frequency of 5.2625 MHz, with a bandwidth of 25 KHz and a maximum range of 200 Km. Within the HF radar coverage area surface currents are measured. Data are also collected from which wind directions and significant wave height can be calculated.
