World's Deepest-Diving Unmanned Submarine Lost

Posted by timothy on from the helios-and-then-this dept.

XenonOfArcticus writes "Kaiko, the world's deepest-diving submarine was lost in in late May off Japan, after it snapped its tether as a typhoon approached. Kaiko entered the record books in 1995 by diving 36,008 feet to the bottom of the Challenger Deep - the ocean's deepest point."

    I know this is a tedious point, but there are four oceans, and not everyone knows where Challenger Deep is. Also, it wouldn't hurt to let everyone know that Challenger Deep is allowed to be confused with the Marianas Trench, since Challenger Deep is the distinct section of the trench that reaches the deepest below the surface, almost seven miles.

    An interesting article about how to calculate the ocean's depth was put together by Nathan Becker, a student at the University of Hawaii when the report was written in 2001.

    Hope this helps you find it.
