Smart buoys detect sharks

AUSTRALIAN researchers have recently introduced a smart alert buoyancy device that can detect the presence of sharks in the sea and send a signal to the rescue team.

Smart buoys are anchored in a sealed container under water. This box is responsible for signaling the sonar to the surrounding water. The interior of the float will analyze incoming signals to determine the appearance of sharks or shark-like shapes.

Goyag says the buoy can also determine the way water moves in certain objects, thereby narrowing the possibility of shark confusion with other species such as dolphins.

Intelligent buoys will be located offshore, in parallel with the beach. When it detects sharks, it sends a warning signal via satellite to the rescue force's smartphone. Rescue workers will use the form of alarm to warn swimmers ashore.

According to researchers at Optus, the warning system is not only safe for humans but also easy to install and maintain compared to other methods. It can detect all kinds of sharks, including those caught or tagged.

Smart float technology has been successfully tested in Sydney Harbor Park and Australia's Abrolhos Islands. The team expects the system to be used soon.
