Clever Buoy is a smart ocean buoy that will help protect you from sharks when surfing by using new sonar technology to detect shark-sized objects in coastal waters. The sonar can identify shark-sized objects 2 metres or more that are swimming. Future development of the buoy will involve inbuilt decision?making systems which will differentiate the object as a shark or mammal, such as a dolphin or whale, with an appropriate response. When detection is made by the Clever Buoy, an alert is sent to relevant audiences, including lifeguards, using Google+ circles, via the Optus Network. Clever Buoy was designed by Western Australian company Shark Mitigation Systems. https://www.engineersaustralia.org.au/News/whos-clever-buoy-shark-spotting-technology
