Is it still #sharkweek this week? - http://clapway.com/2015/07/14/why-has-the-number-of-shark-attacks-risen-on-the-east-coast/

Previously, it wasn’t often that you would hear about shark attacks happening on the East Coast. The annual average of attacks in the area is 6, so understandably people are worried that the number has risen to 11 in only the past few months. You can be sure that you won’t see me on that coast for a while, however, I have a friend who’s family is stationed there, and the concern for their child’s safety on the beach is growing with each attack (understandably so).


Recent Shark Attacks


There have been various attacks this summer on the coast of the Carolinas. In less than a month, the news had reported a total of 8 attacks. The most recent attack was along the North Carolina coastline and involved a Camp Lejeune Marine. Shark experts warn people that typically, sharks are just curious creatures. Many surfers meet them while out on the water and live to attest to that fact of their curiosity. However, that doesn’t seem to be the case lately.

Why Are These Shark Attacks Happening?


Different theories have surfaced in attempts to explain why there are so many more shark attacks this year. Various media outlets are covering these incidents, hoping to bring awareness to the fact that these waters may not be too safe at the moment.


Unfortunately, scientists don’t have a definite answer as to why the number of attacks has risen. They are researching various reasons as to why the marine life might be more prevalent in the area lately. Could it be that there are just more people in the water? These two states have apparently grown in popularity for tourists, not to mention the bases of military personnel stationed there with their families.


It makes sense that there would be more exposure to attacks if there are more people in the water. The species of sharks believed to be attacking people are still unknown, creating another obstacle in finding out the cause of the rise of attacks.

Another possible scenario is that the sharks are being drawn closer to the coastline due to shark fishing, which is still legal in the area. Fishermen are throwing bait and chum into the water to attract the animals, allowing them to get closer to more populated areas. A personal theory is that because we have a multitude of media covering every topic out there currently and the coastlines might not actually experiencing more activity but we are just able to report more on a grander scale a of late.


NPR interviewed George Burgess, from the International Shark Attack File associated with the Florida Museum of Natural History, asking him what he thought the cause could be. It seems that this expert thinks it has more to do with oceanographic factors, such as the water heating up and becoming increasingly salty in areas where that is not normally the case.


What You Can Do to Keep Yourself Safe


The most important thing you can do to keep yourself safe this summer in the water is to know and be aware of your surroundings. If you see people fishing in an area, steer clear of it.


According to Shark Expert Larry Cahoon, sharks hear very well and know the sound of a struggling fish on a line. He also advises that you never swim alone. Many shark attack survivors were lucky because they had immediate aid from people close by.


Whatever the reason in the influx of shark attacks, I think it’s safe to say that the shores will probably see much less traffic this summer. Hopefully scientists and researchers will be able to give us an answer to the cause in the rise of attacks soon, otherwise the Carolinas might suffer economically without the appeal to tourists they usually have.

Keep safe from shark attacks with this technology! - http://clapway.com/2015/06/24/great-white-nope/

I love the beach. I feel so calm lying on the warm sand with the sound of the waves hitting the shore around me, until my feet hit that water and I’m reminded of the menacing creatures that lurk further out. For the water-wader, you really only worry about jellyfish or the sea shells cutting your feet (depending on what beach you’re on of course.) But for those of us who like to be out in the water either swimming, surfing, diving or fishing, we have much bigger worries swimming through our mind. I have this terrible fear that if I get too far out, I’m going to get attacked by a great white shark. I’ve never even seen the movie Jaws (shocking, right?) but I just know that will be my life the minute I exceed ankle-deep water. Maybe it is a somewhat irrational fear. Statistically, shark attacks are pretty rare — and great white shark attacks even rarer, by that logic.


Recently, I read about a shark encounter that really got me thinking. There were 2 men surfing at Hermosa Beach in California last week around 10 A.M. and they encountered a shark. This is reportedly twice now that this same shark has been encountered and it seemed to be growing less weary of humans. After reading this, I became intrigued and started researching more shark sightings and apparently, they’ve become more frequent this year…


While reading more stories, I came across a study done by the University of Western Australia’s Ocean Institute in which they tested different kinds of shark deterrent to see which caused the shark to avoid bait. They tested strobe lights, loud underwater sounds (natural and artificial), a bubble curtain, and an electric field.


Shark Shield


Of these results, the electric field was most effective. This device is actually already commercially available. The Shark Shield can be found on their website, and also at Amazon and Scuba.com. Unfortunately, the cost isn’t just some extra cash you might have lying around (for most of us) but it’s definitely a legitimate investment for someone who spends quite a bit of time out on the water. It’s perfect for the daily surfer or fisher to take with them, because like I said, you never know. While a shark attack (great white or other) is pretty unlikely, as I said before, you never know when it could happen to you! Wouldn’t you want to take the best precaution, especially one that is environmentally-friendly?


Wetsuits That Might Fight Off Sharks


The University has also been doing research to try and figure out some pattern of why sharks attack people, though we’ll never really know for sure. It’s been an assumption among surfers that the reason they get attacked most is because they resemble a shark’s favorite dinner swimming on top of the surface. Unfortunately, there is still limited research to back up any circulating theories.


The theory that the surfers look like seals, however, sparked an idea a while back. Maybe by making the wetsuits look different, it would deter the sharks from the surfers. Dr. Nathan Hart, from the University of Western Australia’s Oceans Institute and school of animal biology, has been working on this research for quite some time. He has also had his hand in helping to make two anti-shark wetsuits. The suits are designed with a specific combination of colors and patterns intended to differentiate the person from a seal.


I love marine life and I am so interested in learning about it, especially sharks. As scary as they are, they’re incredibly interesting animals and it seems often times they’re misunderstood.


I will love them as long as I’m far, far away from them safe in my house. It’s safe to say I will probably always remain terrified of the deep end of the ocean, but it’s cool to think that we have the technology to keep ourselves a little bit safer in the sea.
