Research Vehicle Reaches the Bottom of the Ocean

timothy found BBC coverage of the voyage of the Nereus, which on May 31 dove to the bottom of the Challenger Deep in the Marianas Trench. Only two vehicles have accomplished this feat before, the last 11 years ago. "The unmanned vehicle is remotely operated by pilots aboard a surface ship via a lightweight tether. Its thin, fibre-optic tether to the research vessel Kilo Moana allows the submersible to make deep dives and be highly manoeuvrable. Nereus can also be switched into a free-swimming, autonomous vehicle. ... The Challenger Deep... is the deepest abyss on Earth at 11,000m-deep, more than 2km (1.2 miles) deeper than Mount Everest is high. At that depth, pressures reach 1,100 times those at the surface."

    Nobody cares about your mother's cunt. It's greasy, it's smelly and you could park a suburban in that goddamn thing, and it doesn't help matters that she's a white female. Get it away from me.

    Somebody smarter than myself, please comment on why we need a cable over a distance of 11km? There's a ton of off-the-shelf radio equipment that can easily handle that distance with very high bitrates.

    really? a ton of radio equipment capable of transmitting through 11km of water? oh, you meant through air? wtf does that have to do with this? 802.11 signal strength fluctuates with the humidity in the air, you dont think 11km of water might have some affect on signal propagation?
     

    I'm referring to dielectric effects and the fact that the dielectric constant would not be constant in this sort of operation. But would it be "constant-enough"?

    could you have any more of a wank fest? did you just learn the word dielectric and feel the need to try it out and impress some geeks? the "IM A FUCKING MORON" sign on your forehead is a dead giveaway

    Pretty poor troll. Anyone who knows the existence of words like "dielectric" already knows the answer.

    Next time pay more attention to playing dumb. You are out of your depth, troll-wise.

    Why the fuck do you think people are using SONAR underwater, and not radio?

    This is the way to find new life. Every year a lot of new sealife is found which mankind did not know about before in the deep of the oceans. And maybe it is possible to find in the future what is going on in the Bermuda triangle and what is the cause of the different magnet behaviour in that area http://www.asian-porn-teens.com/ http://www.geisha-sluts.com/
