Tritech Sonar to Spot Sharks in U.S.

The sonar system, which was first developed and deployed by Shark Mitigation Systems (SMS) in Australia, is being recommended for use in Southern California.

The United States coastline has seen an increase in the shark population, where some of the predators can measure up to 12 feet in length, posing a significant threat to surfers and beach goers.

The SMS marine monitoring system utilises Tritech Gemini 720is multibeam sonar technology in conjunction with its SharkTec software that has the capability to detect and track shark activity, providing an early warning to the relevant authorities managing beach safety. Tritech’s original high-definition sonar imaging software, conventionally used in the subsea oil and gas sector, was adapted by utilising shark and marine activity data collected by SMS.

One of the main benefits of the marine monitoring system for detecting sharks over other available systems is that it offers a non-invasive solution. Other shark management strategies typically include the use of drumlines, sharknets and tagging systems – all of which are potentially harmful and invasive.

Scott McLay, Tritech’s sales director, said: “Tritech has a strong philosophy of investing in research and development; this ensures we are at the leading edge of underwater technology innovation. The 720is sonar and associated software is just one product of that philosophy, and the company has more developments planned over the coming months. Additionally, the application of sonar technology in shark mitigation is an exciting development as it opens up additional possibilities of using multibeam sonars in other mammal and fish monitoring scenarios.
