Brains over brawn in latest shark deterrent methods
Surfersvillage Global Surf News, 15 February, 2016 - Bondi Beach is deploying shark-detecting sonar buoys as part of the government’s plan to stem an increase in shark encounters off of New South Wales and elsewhere.
NSW Primary Industries Minister Niall Blair said it was part of his Government's $16-million shark strategy and is the “Holy Grail” of shark deterrent methods.
The buoys have a microprocessor that analyses large, swimming objects by pinging sonar off another component anchored on the ocean floor. When a large, swimming object is spotted the buoy system sends a satellite signal incorporating Google+ to alert those on hand to deal with the shark.
According to ABC.net, if successful, other buoys will be deployed near South West Rocks, Lennox Head, Kingscliff, Coffs Harbour, Port Macquarie and Evans Head. If they perform well, a further 10 will be deployed along the coastline north of Sydney to Forster at a later date.
The “Clever Buoy” is a joint-venture R&D project involving Perth-based Shark Mitigation Systems, Optus and Google. Craig Anderson, one of the buoy’s inventors, said Clever Buoy's ability to detect sharks had a success rate of at least 90 per cent.
"It uses a multi-beam sonar which is a relatively new sonar technology, coupled with some software which is very much like facial recognition technology for marine life," he told ABC
