Shark Monitoring Network

Shark Monitoring Network

06 November 2013

The Shark Monitoring Network (SMN) consists of 30 satellite-linked receivers, which provide land managers and relevant authorities with near real-time alerts of tagged sharks at key locations, enabling beaches to be closed when needed. 

Sharks are fitted with acoustic tags which emit a sequence of low frequency ‘clicks’ that give each tag an audible identification number. These unique signals can be detected and recorded when the shark swims within 400-500m of an acoustic receiver. 

Satellite-linked Shark Monitoring Network receivers are currently located throughout the Perth Metropolitan area, Geographe Bay, Yallingup, Gracetown, Albany and Esperance. Receiver locations can be viewed on the SharkSmart activity map. 

The SMN is one of the largest and most sophisticated research and public safety projects of its kind, providing vital public safety warnings that may help save peoples’ lives.

The SMN began in 2009, to see if it was possible to monitor the movements of tagged white sharks off the metropolitan coast, and to use new satellite-linked technology as an early warning system when tagged sharks swam close to popular beaches. For more information, refer to the SMN Research Project page.
