Ocean radar stations have been deployed at six sites around Australia. Two radar stations are required at each site to produce surface current maps in the area of common overlap.
IMOS has several radar sites located at the Capricorn Bunker Group on the Great Barrier Reef (Queensland); Coffs Harbour (New South Wales); Bonney Coast and Gulfs (South Australia); Rottnest Shelf and Turquoise Coast (Western Australia).
The Capricorn Bunker Group site in Queensland, is a WERA phased array system consisting of two stations: TAN: Tannum Sands, Location: 23.9416°S, 151.3706°E and LEI: Lady Elliot Island, Location: 24.1113°S, 152.7128°E. The stations began operation in November 2007. This station support research around Heron Island and the Capricorn/Bunker Groups.
The Coffs Harbour site, in northern New South Wales, is a WERA phased array system comprised of two stations: RRK: Red Rock, Location: 29.9839°S, 153.2312°E and NNB: North Nambucca, Location: 30.624°S, 153.0111°E. The station began operation in March 2012. This station aims at observing the East Australian Current (EAC) characteristics and dynamics of the shelf, wave spectra and sediment transport.
The Bonney Coast site, in South Australia, is a SeaSonde direction finding system consisting of two stations: NOCR: Nora Creina, Location: 37.3286°S, 139.8498°E and BFCV: Black Fellows Cave, Location: 37.9395°S, 140.4566°E. The station began operation in July 2010. This SeaSonde station was positioned to observe the coastal upwelling and pulse of the Leeuwin Current and meteorological fronts approaching landfall.
The South Australia Gulfs site, in central South Australia, is a WERA phased array system containing two stations: CSP: Cape Spencer, Location: 35.2956°S , 136.8826°E and CWI: Cape Wiles, Location: 34.9428°S , 135.6825°E. The station began operation in December 2009. The South Australia Gulf station is located near the Gulf entrance to examine surface currents and wave climate in the entrance to Spencer Gulf and St Vincent’s Gulf to study inter-shelf mixing along the eastern shore of the Great Australian Bight and the Gulfs. Additional priorities are the progress of meteorological fronts across the eastern side of the Bight.
The Rottnest Shelf site, in Western Australia, is a WERA phased array system that includes two stations: FRE: Fremantle, Location: 32.0314°S, 115.7461°E and GUI: Guilderton, Location: 31.3417°S, 115.4894°E. The station began operation in March 2010. This station aims to observe the dynamics of the interaction between the open ocean and Perth Canyon.
The Turquoise Coast site, in Western Australia, is a SeaSonde direction finding system that has two stations. The initial installation included CRVT: Cervantes, Location: 30.5065°S, 115.0592°E (until 30 Nov 2012) and SBRD: Seabird, Location: 31.2811°S, 115.4442°E (until 10 Mar 2013) and the current stations are: GHED: Green Head, Location: 30.073 °S 114.967 °E (starting on 12 Dec 2012) and LANC: Lancelin, Location: 31.027 °S 115.329 °E (starting on 1 Apr 2013). This station was positioned to support research on meanders of the Leeuwin Current onto the shelf and dynamics of return flows closer to the coast.
