Brief description The Tannum Sands (TAN) HF ocean radar site (-23.942 S, 151.371 E) is one of two HF ocean radars covering Heron Island in the Capricorn Bunker Group (CBG) in the southern region of the Great Barrier Reef Marine Park World Heritage Area. The other HF ocean radar station is at Lady Elliot Island. The HF ocean radar coverage is from the coast to beyond the edge of the continental shelf.
The TAN HF ocean radar is a WERA phased array system with a 12-element receive array. 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.
Australia’s Integrated Marine Observing System (IMOS) is enabled by the National Collaborative Research Infrastructure Strategy (NCRIS). It is operated by a consortium of institutions as an unincorporated joint venture, with the University of Tasmania as Lead Agent.
