Buoy reports Hai-Alaaaarm!

For years now, the global number of Haiattacken. Australia wants this development now to prevent – with a clever buoy. You recognize the shark from a safe distance and alerted the Lifeguard.

In the last year alone there were in Australia 18 incidents in which sharks people attacked. In 2014 there were eleven. So is Australia in the Ranking of the countries with the most Haiattacken always up there. Only in Florida to pass such attacks even more often – 28 Times in 2014.

On the hit list

The consequence was that the Australian government’s 2014 short-term
Tötungsgenehmigung for Tiger and bull Sharks, as well as endangers classified White sharks, spoke to the Population to curb.

In response, thousands of people on the street to demonstrate. Because of this the risk of such attacks would reduce stand strong in the criticism. Originally the Tötungsgenehmigung until 2017 to be issued, environmentalists and the Australian Environmental authority EPA (Environmental Protection Authority) could be the action, however, after a short time stop.

2014 won Australia’s sharks! The Tötungsprogramm was stopped – there are other ways, Haiattacken to prevent.

To beachgoers and
Protecting sharks, the Western Australian company Shark Mitigation Systems (SMS) therefore, together with the telecommunications company Optus think of something else: A shark-friendly alert system that the animals still have a safe distance identified so that sufficient time remains to people or surfers in the vicinity of the alert.

The company SMS that describes the System as a kind of “face recognition for marine life”. The technology has a 90-percent success rate, ” said Craig Anderson, involved in the development of is, when you Open up the test facility at Bondi Beach in Sydney.

How does it work?

“Clever Buoy” is the name of the System, to German: clever buoy. The principle is simple: The 25-kg buoy is 500 meters from the coast, anchored to the sea bed. From there emits a sonar sound waves. As soon as this hits an object, they are reflected back.

The measurement system is programmed so that when “haifischgroßen objects” – from two metres and more – strikes.

Device now a contemporary fish in your visor, the Software detects whether it is a shark or not. If Yes, then the buoy Alarm and informed the lifeguard on duty via the App.

The System is cheaper and more environmentally friendly than nets and Traps. Trapped every year, thousands of animals and die painfully. Also, it should be the sounder sharks and other marine life, do not disturb, i.e. it is the Part of the developers.

Shark or whale?

But how does a buoy, whether a beast, over two meters tall, is also like a shark is? Also dolphins or whales might, for example, into the Grid of the buoy is advised.

Apparently not. Because it is in the detection of not only the size, but also to the behavior in the water that the System recognizes. “Sharks have in comparison with other marine life, an entirely different pattern of movement”, it says on the website of the Clever Buoy.

So looks like the App on the Smartphone, the Haialarm to the Lifeguard passes. Here is the air or the water pure.

The test mode starts now

At Bondi Beach – one of the most famous beaches in the world – are for the time being, eight of these buoys. Each individual observed an area with a radius of about 60 meters. The Plan and the System works, should be ten more buoys added.

At other beaches is the use of so far not planned. But: The probability of a shark being attacked, despite rising incidents is still very low. Rather it carries an elephant, a flash of lightning or a falling coconut into the Beyond. Nevertheless, should you once in a Situation where we have, here are some tips
how to get an emergency really is.
