Remote-controlled research sub lost in Pacific

May 11, 2014

A remote-controlled research sub exploring some of the deepest depths of the Pacific Ocean has been lost.

The Woods Hole Oceanographic Institution says the Hybrid Remotely Operated Vehicle Nereus was lost during its six-mile dive to the Kermadec Trench on Friday. The sub was being operated as part of the Hadal Ecosystems Studies (HADES) Program funded by the National Science Foundation.

The hadal zone is the name given to the deepest depths of the ocean, named for the underworld of Greek mythology. The Kermadec Trench is the fifth-deepest in the world, about 75 miles off the coast of New Zealand.

Woods Hole science editor Ken Kostel called the loss of Nereus a "body blow" but the research team will continue their work to learn more about "a place that does not give up its secrets easily."

Saddest part is they may never discover what went wrong...

Yeah, they were just waxing poetic about how this submersible was a game-changer, and that The Deep was about to be arm-twisted into giving up all its secrets.

I suppose Leviathan is no more fond of hubris than The Gods.....

I guess a sentence or two about how and why it was lost was too much at this time? It seems that they might have a chance to recover it, if it wasn't destroyed.

I'd guess a definitive cause will have to wait a lengthy examination of the last telemetry. Kind of like what happened following the Columbia STS failure. At least there were no people on board this time.

Maybe they should send these remote control subs down in pairs, as practiced by scuba divers.
