Kevlar Protects Cables From Sharks, Experts Look For Protection From Shark Week

Brandon Butler writes As an ode to Shark Week: Sharks have been known to show an appetite for fiber cables underwater, and last week a Google official said to prevent sharks from wreaking havoc on the company's trans-Pacific fiber lines, it wraps them in Kevlar. It's believed that the emission of electrical currents from the fiber piping is mistaken by sharks occasionally as prey. In related news, a growing number of scientists are becoming disgruntled with the Discovery network's sensationalist programs. Many shark experts are refusing to work with the channel after such programs as their Megalodon "documentary" and their latest Shark of Darkness (not to mention the mermaid special, which was sadly missing a singing crab.)

Sockatume writes The Verge has an article on Discovery's hugely successful Shark Week, discussing how the increasing sensationalist special event misrepresents science and exploits nature and local history for shock value. Scientists who appeared in and were misrepresented by the channel's programming are beginning to encourage their peers to stay away from the Discovery network, which stands by the programming 's viewing figures.

  1. Does fiber containing photons have current? by postbigbang · · Score: 3, Interesting

    Is this just static building up along the lining, or is there actual photonic/electrical conversion going on?

      It's actual photonic capacitance causing the induced charge within the lining. Some recent research has been done into reducing the self-capacitance of synthetic cable sheathing, and counterpolarization of the cable's dielectric field has proven to be one of the more effective methods. The main problem is that it increases the impedance to an unacceptable level, causing ghosting. But using systemic impedance matching has been found to mitigate this effect.

      In the article it mentions that power is run on the lines to power repeaters to keep the signal going. This is what causes the electrical current.

      Repeaters are powered by a constant direct current passed down a conductor near the center of the cable. All repeaters in a cable are powered in series. Power feed equipment (PFE) is installed at the terminal stations on the land. These PFEs inject huge voltage into the line - 3,000, 4,000, and up to 10,000 volts - to power each repeater on the cable (now you can understand why Jaws went to shark heaven after his mid-morning snack).

    8. Re:The Discovery channel? by Rei · · Score: 4, Insightful

      Both are terrible, and started going downhill around the same time, racing each other to the bottom - beginning in 2005 (when you started getting shows like Deadliest Catch and Decoding the Past, which became the prototype for many future series of increasingly less "reality"), and then full force by 2007 where you start getting too many shows to name.

      One thing that drives me crazy almost as much as the blatant pseudoscience presented as fact is the extensive acting presented as reality. I mean, okay, I get it, a purely "reality" program is pretty much impossible, the very requirements of filming it make it so. Even in stuff like Les Stroud's "solo" work he always had a base camp just a couple kilometers away from him and stayed in communication with them by radio. But now the stage guidance, product promotion, and "weekly scripted adventures" have gotten so absurd and obvious, they don't even try to hide it any more. I thought that they couldn't get any lower than the bogus survival show Man vs. Wild (where the host pretended to be living in homemade shelters and surviving off wild food, when he was actually staying in luxury hotels and show consultants prepped everything from making "rafts" for him to releasing "wild" animals for him to catch). But now almost all of their shows are like that or even worse. And the product promotion, my god - have you seen the Pawn Stars plugging for Skype? If you're going to have your "reality show" stars plug a product in your show, at least get people who can act.

      The changes are so visible with time, too. Take Mythbusters for example - watch some of the early eps and compare with the modern eps and look at how much more is obviously staged acting with everyone reciting a script (not to the extent of Smash Labs, but still). Apparently Discovery Communications has decided that this is what people want to see - bad actors going on "daily adventures" and having "witty banter".

      I don't/didn't have a problem with Deadliest Catch. It's definitely jumped the shark (to stick with the theme of this "article"), having long outlived the point where one can get a better appreciation for the industry, but I still enjoy it enough to watch if it's on. I could do without the explosion of reality shows that followed in it's wake though.

      Shark Week definitely jumped itself last year with Megalodon, and that seems to be the tip of the iceberg, unfortunately. I will admit that I'm glad to see less muddying the waters with "sharks aren't dangerous, 'mkay" nonsense though. Nobody would assert that a lion mistook a human for a gazelle, but apologists insist that sharks just get confused when they attack people. The fact is that sharks eat protein, humans are a source of protein, and sharks don't mind eating us.

      As for the History Channel, it started its descent long before 2005. In the 90s, it was facetiously called the Hitler Channel, as easily half of its programming was dedicated to WWII in Europe. You could've made a drinking game out of it -- if you wanted to be three sheets to the wind. It seemed like the addition of conspiracy shows was trying to capitalize on the popularity of the X-Files at the time, but that's just my perception.

    As a scientist quoted in any of the current Shark Week "dramas" (they don't even rate the "docudrama" label), I'd sue Discovery for misrepresentation and libel. They quoted out of context and stitched together several scientist's different takes (not to mention failing to inform them about the subject being talked about, rather lying to them about the nature of the interview). As a consequence, the "scientist" never said any of the things they were purported to say.

    Don't watch Shark Week. Don't watch Discovery/History/TLC or anything like that any more. heck, even NatGeo is bad. It's a shame.
