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.

    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).

    ...or it's the thousands of volts pumped into the cables to power the repeaters required every couple hundred kilometers.

    I don't know, I think the History channel (aka Conspiracy channel) might beat them for number 1.

    They wrap the sharks in kevlar? Now there is an exciting job. How much does it pay?

  5. Most documentaries suck by rolfwind · · Score: 5, Insightful

    For the past 15 years, nearly all the channels such as history channel, discovery, etc have been nearly wothless, waste your time with ratings tactics, etc. Some physics series (NDT, Brian Cox) and maybe animal planet being an exception?

    It's easier just to read up on the rest without the bullshit, the commercials, and the ratings grab tactics. Even on netflix, it's rare that a documentary is worth watching, because of the editing geared towards TV.

    It's telling when the most worthwhile educational show the last years came out on Fox.

      No. PBS is still huffing along, churning out Nova, Frontline, Nature, American Experience, Wild!, Secrets of the Dead, History Detectives, Charlie Rose, This Old House, and more, like they have for decades.

    I just knew someone would bring them up. You are definitely correct. The H2 Channel is right up there too. They were showing Mayan apocalypse shows months after we were all destroyed.

    And to think, once upon a time they were actual decent networks. Now it's ancient alien swamp logging pawn shop owners.

    Dunno, it seems to be part of a larger trend:
    Discovery Channel -- full of fiction and unscientific crap
    History Channel -- full of fiction and unscientific crap
    Science Fiction Channel -- full of fiction about unscientific crap (its supposed to be fiction about scientifically plausible stuff -- if they want magic even that would be acceptable if only they would invent a name for it instead of pretending electromagnetism is magical)
    Politicians -- full of fiction and unscientific crap
