Brief description

The Turquoise Coast (TURQ) HF ocean radar system covers the area of shelf between Seabird and Jurien Bay and is the logical continuation of major research efforts to understand the role of the Leeuwin Current System (Leeuwin Current, the Leeuwin Undercurrent and Capes Current) in controlling not only the physical system but also its links to both pelagic and benthic ecosystems. In contrast to eastern ocean basins, which are highly productive, Western Australia experiences an oligotrophic environment. The Leeuwin Current is a shallow (<300 m deep), narrow band (< 100 km wide) of warm, lower salinity, nutrient depleted water of tropical origin that flows poleward from Exmouth to Cape Leeuwin and into the Great Australian Bight. The Current plays a dominant role in controlling the marine life and climate of the region. Questions which may be addressed by using the HF ocean radar data from TURQ (and ROT) include the variability of the Leeuwin current and its response to the ENSO cycle; Leeuwin Current eddies and their interaction with the shelf waters; and the interaction between the Leeuwin Current, the Capes Current and coastal current during the summer. This is an important region for Western Rock lobster recruitment, and the meanders of the warm Leeuwin Current influence the ecology. This is a region with low tidal range and with a coastline subject to strong sea breezes and intense winter storms. Coastally trapped waves may be generated by the winter weather systems and by tropical cyclones in the summer. The TURQ HF ocean radar system consists of two SeaSonde crossed loop direction finding stations located at Seabird (31.281 S 115.444 E) and Cervantes (30.506 S 115.060E). From 2012-12-15T11:00:00 the Cervantes station has been replaced by the Green Head station (30.073 S 114.967E) and from 2013-03-19T00:00:00 the Seabird station has been replaced by the Lancelin station (31.027 S 115.328 E). These radars operate at a frequency of 5.211 MHz, with a bandwidth of 50 KHz, a maximum range of 200 Km and a range resolution of 3 Km. Within the HF radar coverage area surface currents are measured. The TURQ area of coverage has a small overlap of commonly observed ocean with the Rottnest Shelf (ROT) WERA HF ocean radar system on its south side. Together, the TURQ and ROT systems provide continuous monitoring of the shelf from Fremantle to Jurien Bay.
