The Australian Coastal Ocean Radar Network (ACORN) facility comprises a coordinated network of HF radars delivering real-time, non-quality controlled and delayed-mode, quality controlled surface current data into a national archive.

Based on experience in Europe and the USA, deployment of these radars is expected to make a profound change to coastal ocean research in Australia. HF radar provides unprecedented time-resolved surface current maps over the monitoring sites for physical and biological ocean research.

Deployment of the radars is in support of regional nodes where there is a range of identified questions concerned with boundary currents and associated eddies and their interactions with shelf water and topography. In turn these are linked to productivity, connectivity of biological populations and phenomena such as coral bleaching and diseases. It provides a basis for applied research in wave prediction and offers test sites for hydrodynamic modelling.

The equipment comprises long-range WERA and medium-range WERA systems and long-range SeaSonde systems, and associated spares and transport infrastructure. An existing system that was installed by James Cook University in the Capricorn/Bunker region around Heron Island on the Great Barrier Reef was integrated into the network. An HF radar acquisition by a consortium led by South Australian Research and Development Institute in South Australia was also integrated into the network.
