Myrmidon Reef

A Wireless Sensor Network was deployed at Myrmidon Reef in the central Great Barrier Reef in late 2009.

The installation used the existing Australian Institute of Marine Science (AIMS) Tower (triangle on map) for the base station with sensors running from this. The tower was damaged in early 2011 by Cyclone Yasi and so a temporary buoy was installed (yellow circle on the map) for the last two years. The tower was replaced in late 2014 and the buoy decommissioned in early 2015.

Myrmidon Reef is an important reef as it sits on the edge of the continental shelf and so is a point where ocean waters enter the Great Barrier Reef matrix. As such it is an important place to measure oceanic upwelling – that is the transport of deep oceanic water onto the shelf.

Myrmidon acts as the most oceanic of three sites (Myrmidon Reef, Rib Reef and parts of the Orpheus Island site) that were set up to track cross-shelf incursions of deep ocean water and the role these upwelling events play in coastal productivity.

The Myrmidon Reef Senor Network was decommissioned in December 2014 previous data is available on the Australian Ocean Data Network (AODN) Portal.
