Northwest Western Australia

In May 2011 the West Australian state government funded the deployment of the Kimberley and Pilbara arrays in January and February 2012. The four moorings of the Kimberly array were deployed at 50, 100, 200 and 400m isobars on the continental shelf. The three Pilbara mooring were also deployed on the continental shelf at 50, 100 and 200 isobars.  In August 2014 due to the cessation in WA Government funding the Kimberly and Pilbara arrays were removed.
