IMOS - ACORN - Direction finding ocean radar system (Seasonde)

Coastal ocean surface radar is a land-based technique which uses scattering from the rough sea surface to obtain echoes which are Doppler shifted by the dynamics of the sea.  It has been shown (Crombie, 1955) that the scatter is predominantly a Bragg interaction between the radio wave and the sea surface gravity wave that is propagating in the same direction and with half the wavelength of the radio wave.  This Bragg interaction gives two strong first-order lines in the echo spectrum; one from the resonant gravity wave moving radially away from the station, and one from the resonant gravity wave moving towards the station.

Direction-finding systems determine the azimuthal direction of a source point by comparing amplitude and phase signals on crossed loop receive antennas. The direction finding calculation is done on Doppler shift spectra for a specified range which includes return echoes from all azimuths.  This means that the spectra are spread and second-order echoes from one direction are swamped by the first-order echoes from other directions.  Consequently, parameter extraction using second-order echoes is not possible on a routine basis.  Directional wave spectra at the location of each radar station are produced by analysing the full azimuthal spread of first-order echo amplitudes, and wind directions are derived across the grid points by taking the ratio of the positive and negative Bragg echoes.

SeaSonde HF ocean radar stations are used on the Turquoise Coast (Seabird and Cervantes), Western Australia, and on the Bonney Coast (Nora Creina and Blackfellows Cave), South Australia.

IMOS - ACORN - Coffs Harbour HF ocean radar site (New South Wales, Australia)

The Coffs Harbour (COF) HF ocean radar site is located near the point at which the East Australian Current (EAC) begins to separate from the coast.  Here the EAC is at its narrowest and swiftest: to the north it is forming from the westwards subtropical jet, and to the south it forms eddies and eventually the warm water moves eastwards across the Tasman Sea, forming a front with the cold water of the Southern Ocean.  

The connection between coastal and continental shelf waters is fundamental to the understanding of the anthropogenic impact on the coastal ocean and the role of the ocean in mitigating urban marine water quality. The oceans off Eastern Australia and in particular in the region of New South Wales have a complex circulation structure, and are strongly connected with other regional seas and currents. 

The East Australia Current (EAC) flows from tropical regions southward along the NSW continental slope, bringing tropical biota southward. These current structures provide strong physical and biological connectivity, allowing substantial transport and dispersion of biota between regions, and influencing the transport and upwelling of nutrients, which are fundamental to biological productivity.  

The COF HF ocean radar is a WERA phased array system with 16-element receive arrays located at Red Rock (-23.942 S, 151.371 E) to the north of Coffs Harbour and North Nambucca (-24.111 S, 152.713 E) to the south.  The area of focus is off Coffs Harbour where IMOS and the NSW government have mooring sites.  These radars operate at a frequency of 13.920 MHz, with a bandwidth of 100 KHz and a maximum range of 100 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.

IMOS - ACORN - Capricorn Bunker Group HF ocean radar site (Great Barrier Reef, Queensland, Australia)

The Capricorn Bunker Group site is in the southern region  of the Great Barrier Reef Marine Park World Heritage Area (GBR).  The HF ocean radar coverage is from the coast to beyond the edge of the continental shelf.  This is an area where the East Australian Current (EAC) meanders as it moves south from the Swain Reefs and loses touch with the western land boundary.  The area is dynamic with warm EAC water recirculating and being wind-driven northwards along the coast inside the GBR lagoon.  The recirculating warm water contrasts with the upwelling tendency of the parts of the EAC which continue to move southwards.  The CBG radar is ideally placed to follow filaments of different water types and to investigate their impacts on coral reefs and fisheries.  

Applications of the CBG radar data are in the frequency and location of regional upwelling that fuels productivity, and in the connectivity between reefs and islands.  At the central point of the CBG area of coverage is the  Heron Island Research Station which hosts many coral reef and ecology research programs.  The data will also be useful for validation of the operational Bluelink model, and the embedded higher resolution Whole-of-Reef model.   

The CBG HF ocean radar is a WERA phased array system with 12-element receive arrays located at Tannum Sands (-23.942 S, 151.371 E) and Lady Elliot Island (-24.111 S, 152.713 E).  These radars operate at a frequency of 8.348 MHz, with a bandwidth of 33 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.  

The capital funding for this system was provided originally as an ARC LEIF Grant, assisted by contributions from James Cook University, The University of Queensland, the National Oceanic and Atmospheric Administration and the Australian Institute of Marine Science.

This site was decommissioned in April 2017.

IMOS - ACORN - Bonney Coast HF ocean radar site (South Australia, Australia)

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
