Western Australia Moorings

What are Western Australia Moorings?

Western Australia Moorings is a collection of shelf mooring designed to monitor the major oceanographic features in the southern west coast of Australia. The mooring arrays are strategically located to monitor coastal upwelling and the structure and variability of the Leeuwin Current in the south west of Australia. Moorings are currently located off Two Rocks and the Perth Canyon, the largest underwater canyon in Australia and a major oceanographic feature of the region.

The location of Western Australia Moorings overlaps with Ocean Radar coverage off Perth and are also co-located with regular Ocean Glider missions. The cross-validation of the different data streams of these IMOS Sub-Facilities provides an in-depth understanding of the regions oceanographic and coastal processes and the important interactions between the Leeuwin Current and the wind-driven Capes Current and their associated eddy fields. The historical deployment of an Acoustic Observatory in the Perth Canyon provides baseline data on ambient oceanic noise, presence of fish and mammals of this important feature of the ocean floor and its role in oceanic productivity of the region. The maintenance of the Rottnest Island National Reference Station by Western Australia Moorings, in addition to the shelf moorings provides valuable information on the south-west region of Australia’s ocean.
