Lucie Bornier, Fanny Ruyer, Emilie Blanchard, Chloé Coupeau, Arthur Floc'h ACCESSED RESOURCES Emilie Blanchard Videos: Video 1 : La Réunion : comment expliquer les attaques de requins ? http://www.francetvinfo.fr/faits-divers/requins/attaque-requins/reunion-comment-expliquer-les-attaques-de-requins_883131.html Sharks fishing is forbidden since 1999, so the number of squales is increasing. In addition, overfishing of the other species is one of the reasons why sharks are increasingly near from the coasts. Video 2 : Clever buoy http://www.sharkmitigation.com/clever-buoy-new.html The clever buoy detects the sharks with an electromagnetic system and transfers data to a satellite which gives it to the computers in locals in the beach. However, there is a blind zone. Video 3 :Shark Attack Mitigation Systems http://www.gentside.com/requin/des-chercheurs-developpent-deux-combinaisons-anti-requin-pour-les-surfeurs_art52917.html
In this video, we can see that two professors develop two wetsuits to avoid sharks attacks.
Book : Profondeurs – Guillaume NÉRY (en collaboration avec Luc LE VAIILANT).
Documents: Article 1 : Shark-detecting sonar system promised by Coalition if it wins NSW election – The Guardian http://www.theguardian.com/environment/2015/jan/25/shark-detecting-sonar-system-promised-by-coalition-if-it-wins-nsw-election In Australia, the government decide to give $100 000 in order to finance a shark-detecting sonar technology.
Article 2 : Shark detection system http://www.pressreader.com/australia/joondalup-times/20150908/281500750024158/TextView A new system of buoys was tested in Mullaloo. They are directly connected to its Beach Safety Command and Control radio system that receives the tagged shark detection and immediately activates a warning sirens and flashing lights to alert beach users.
Article 3 : DETECTION OF SHARKS WITH THE GEMINI IMAGING SONAR http://www.acoustics.asn.au/journal/2014/Vol42No3-Parsons.pdf
With this article I discover that in this system there is a blind zone which is a major problem if we would like to try to detect every single shark.

With the new detecting system, some researchers have discovered that near the buoy, sharks turn around.
Article 5 : L'Australie veut des drones pour détecter les requins http://www.numerama.com/magazine/34326-l-australie-veut-des-drones-pour-detecter-les-requins.html In this article, the government decided to find solutions to prevent sharks attacks.

First description of our project's idea Provide a proposition of title for your project Please answer to the three expected questions: 1. What Problem do you want to solve ? How can we avoid sharks attacks without killing them ?
2. Why does this problem exist? One of the most important reason why there are more and more sharks attacks is that shark fishing is less and less frequent. Indeed, on the island of La Réunion it’s forbidden since 1999 because a human deadly toxine was found in sharks. This precautionnary principle has a direct consequence : The number of sharks increased. According to specialists, overfishing in this region is pushing sharks to get closer to the coasts, looking for food. Consequently, sharks attacks on humans are more likely to happen. In addition, the release of animals’ carcass in the ocean attracts sharks. In the same region, a wildlife park was reserved for water activities with an outlawry of fishing. However, this place is full of fishes and attracts starving sharks. Sharks believe that Surf Boards look like turtles, their favorite food. Basically, sharks attacks are rare but their violence creates an haunt for this animal, that is a real threat for tourism which is very important economically speaking for this island. Nowadays, many systems have been created to reduce sharks attacks, unfortunatelly they weren’t efficient enough to stop those attacks.
