IMOS - ACORN - Turquoise Coast HF ocean radar site (Western Australia, Australia)

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 From 2012-12-15T11:00:00 the Cervantes station has been replaced by the Green Head station (30.073 S 114.967E) and from 2013-03-19T00:00:00 the Seabird station has been replaced by the Lancelin station (31.027 S 115.328 E).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

This radar operates at a frequency of 8.348 MHz, with a bandwidth of 33 KHz and a maximum range of 200 Km and a range resolution of 4.5 Km.  Azimuthally the radar covers a sweep 45 deg either side of a bore sight direction of 47 deg true east of north (approximately north-east).

Within the HF radar coverage area surface current radials are measured.  Data are also collected from which wind directions and significant wave height can be calculated.

This station was decommissioned in April 2017.

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

The South Australia Gulfs (SAG) HF ocean radar system covers the area of about 40,000 square kilometres bounded by Kangaroo Island to the east and the Eyre Peninsula to the north.  This is a dynamic region where warm water from the remnants of the Leeuwin current is moving from the west, and water with varying density is exchanging with Spencer Gulf and the Gulf of St Vincent.  Upwelling events occur from the deep ocean on the south side of the observation area.  This is a key ocean area for aquaculture and fishing, and is a major shipping thoroughfare.  The data from this HF ocean radar system link the dynamics of the Great Australian Bight to the Bonney Coast and on to Tasmania. 

Specific research questions identified by the SA Node of IMOS are: What is the detailed connection between shelf currents and the Flinders Current to non-regional influences (e.g. Southern Ocean, WA)?  What is the nature of oceanic currents and processes (e.g. wave drift, mixing, eddies) that drive both winter and summer cross and along shelf exchange including the summertime upwelling systems and flushing of the gulfs?  How does the ocean circulation, wave drift, eddies and environmental variability affect the distribution of sediments, nutrients, the production of lower trophic levels
(phytoplankton and zooplankton), the dispersal of larvae that underpin productive fisheries in the region and the effects of environment on aquaculture

The SAG HF ocean radar is a WERA phased array system with 16-element receive arrays located at Cape Wiles (34.943 S, 135.681 E) and Cape Spencer (35.294 S, 136.879 E).  These radars operate at a frequency of 8.512 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.  

Most of the capital was contributed by the South Australia Research and Development Institute.

IMOS - ACORN - Rottnest Shelf HF ocean radar site (Western Australia, Australia)

The Rottnest Shelf (ROT) HF ocean radar system covers an area which includes Rottnest Island and the Perth Canyon to the north-west.  The Perth Canyon has the highest marine biodiversity in the region with whale and fish aggregations, and high primary and secondary productions which are controlled by the physical oceanographic processes.  

Combined with the dynamics of the Perth Canyon is the dominant Leeuwin Current which produces a wake on the leeward side of Rottnest Island.   This is a topographically induced up-welling and associated primary and secondary productivity.  The region is influenced by Swan River outflow, submarine groundwater discharges , and waste-water outfalls.  

The ROT HF ocean radar is a WERA phased array system with 16-element receive arrays located at Fremantle (32.031 S, 115.746 E) and Guilderton (31.342 S, 115.489 E).  These radars operate at a frequency of 8.512 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 ROT area of coverage has a small overlap of commonly observed ocean with the Turqoise Coast (TURQ) SeaSonde HF ocean radar system on its north side.  Together, the ROT and TURQ systems provide continuous monitoring of the shelf from Fremantle to Jurien Bay.

IMOS - ACORN - Phased array HF ocean radar system (WERA)

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.

Phased array systems determine the azimuthal angle between the station and a point on the sea surface by forming a narrow beam; the range to the point is set by the propagation delay for the electromagnetic wave.  For the phased array systems, the two radar stations each operate for alternating periods of 5 minutes on and 5 minutes off, and out of phase, so that they can use the same frequency without interfering with each other.  During each 5 minute of operation the radar measures the component of the surface current at each point projected onto the radial from the station to the point.  

At the end of 10 minutes, the radial components of surface currents can be combined from the two stations to find the vector at each position on the grid.  While surface currents are generally the data of most interest, the phased array systems can also produce significant wave heights and wind directions at each grid point and a calculation of the full directional wave spectrum at ranges of up to about half the maximum range (which is 150 km).

WERA HF ocean radar systems are used in the Capricorn Bunker Group (Tannum Sands and Lady Elliot Island), Queensland, at South Australian Gulf (Cape Spencer and Cape Wiles), South Australia, for Rottnest Shelf (Fremantle and Guilderton), Western Australia, and at Coffs Harbour (Red Rock and North Nambucca), New South Wales.
