Quick shark warn­ing sys­tem

Pinjarra Murray Times - - AT THE MOVIES -

MAN­DURAH res­i­dents are push­ing for a trial of a new shark detection sys­tem that would see be­low the wa­ter sur­face, de­tect sharks and send a warn­ing to swim­mers or surfers in “less than one sec­ond”.

Shark Alert In­ter­na­tional chief tech­ni­cal of­fi­cer Chris Mounk­ley, who de­signs and builds pro­fes­sional un­manned air­crafts around the globe, claimed past tri­als of his new sys­tem gave 100 per cent detection.

“This multi spec­tral cam­era sys­tem can de­tect sharks eight to 10 me­tres deep,” he said.

“The most re­cent test in Hawaii de­tected live sharks in rough con­di­tions show­ing the ef­fec­tive­ness of detection over reef, some­thing pre­vi­ously thought im­pos­si­ble.”

Mr Mounk­ley said the drone-fixed cam­eras were linked to a mi­cro­com­puter that used an al­go­rithm to de­tect, in real-time, the sig­na­ture of a shark in the wa­ter.

The multi spec­tral cam­eras would ob­serve a wider stretch of coast­line, four kilo­me­tres long, fly­ing at 80 kilo­me­tres an hour with­out be­ing hin­dered by waves, glare and chop.

If a true detection was found, a warn­ing sig­nal would be sent to alert life­guards who would re­ceive the shark’s lo­ca­tion and where it was trav­el­ling.

Rick Ger­ring, the brother of Ben Ger­ring who was killed by a shark in 2016, said a de­vice would pro­vide “ex­tra surveil­lance” on beaches.

“There’s no sil­ver bul­let when it comes to pro­tec­tion against sharks. How­ever, hav­ing ex­tra surveil­lance if there was a shark around that would get peo­ple out of the wa­ter quicker, track the shark as well as open beaches sooner would be great,” he said.

Mr Mounk­ley said he was in the process of de­vel­op­ing a wa­ter­proof smart watch sys­tem that was 80 per cent com­plete.

Surfers could re­ceive warn­ings in less than one sec­ond, even in re­mote lo­ca­tions.
