    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 From 2012-12-15T11:00:00 the Cervantes station has been replaced by the Green Head station (30.073 S 114.967E) and from 2013-03-19T00:00:00 the Seabird station has been replaced by the Lancelin station (31.027 S 115.328 E).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.

    Temperature data from the TOGA/WOCE transect IX28 across the Southern Ocean has been collected since 1992 and are ongoing. The transect is repeated approximately 6 times a year in the Austral summer, with profiles obtained approximately every 10-50 Km. The data are obtained from XBTs (expendable bathythermographs) deployed by the French Antarctic resupply vessel L'Astrolabe, and are managed by the French Polar Institute (IPEV) and the Joint Australian Facility for Ocean Observing Systems (JAFOOS), a collaborative venture between CSIRO Marine Research and the Bureau of Meteorology Research Centre (BMRC).

    The Nora Creina (NOCR) HF ocean radar site (37.329 S 139.850 E) is one of two HF ocean radars covering the Bonney Coast, South Australia. The other HF ocean radar station is at Blackfellows Cave. The HF ocean radar coverage is from the coast to beyond the edge of the continental shelf. The NOCR HF ocean radar is a SeaSonde crossed-loop direction finding array. This radar operates 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. The antenna bearing is 255 deg true east of north (approximately west by south-west). Within the HF radar coverage area surface current radials are measured. This station was decommissioned in March 2017.

    The Geophysical Data Record (GDR) is available to users within 60 days from instrument sensing. The main geophysical parameters in the GDR product, derived from the Poseidon altimeter on-board the Jason2 satellite, are sea surface height, significant wave height and ocean surface wind speed. Additionally, all necessary magnitudes contributing to the estimation of the sea surface height are provided as well, such altimeter ranges, orbit data (altitude), water vapour correction, geophysical corrections and geophysical references. Finally, other important parameters, intended to help with the interpretation and use of the data for different applications, are provided as well, such as for example backscatter coefficients and a range of instrument and processing quality flags. Both 1Hz and 20Hz sampling data are included. This is a fully validated, high accuracy product. A precise orbit is used, estimated from DORIS, Laser Ranging and GPS measurements. Each file contains data corresponding to a pole to pole pass. This product is mainly targeting climate and science applications.

    The Blackfellows Cave (BFCV) HF ocean radar site (37.940 S 140.457 E) is one of two HF ocean radars covering the Bonney Coast, South Australia. The other HF ocean radar station is at Nora Creina. The HF ocean radar coverage is from the coast to beyond the edge of the continental shelf. The BFCV HF ocean radar is a SeaSonde crossed-loop direction finding array. This radar operates 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. The antenna bearing is 257 deg true east of north (approximately west by south-west). Within the HF radar coverage area surface current radials are measured. This station was decommissioned in March 2017.

    The Bonney Coast (BONC) HF ocean radar system covers an area of the Bonney Coast, South Australia, which has a recurring annual upwelling feature near to the coast that significantly changes the ecosystem from one of warm water originating in Western Australia, to one dominated by cold upwelling water from off the continental shelf. The dynamics of this area and the relationship between ocean circulation, chemistry and sediments control the larval species and the higher marine species and ecosystems in which they forage. The data from this site provide linking observations between the Southern Ocean and NSW through processes that occur on weekly to El Nino time scales. The BONC HF ocean radar system consists of two SeaSonde crossed loop direction finding stations located at Nora Creina (37.329 S 139.850 E) and Blackfellows Cave (37.940 S 140.457 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.
