Woods Hole Oceanographic Institution Loses Deep Sea Vehicle
First time accepted submitter Mr D from 63 (3395377) writes in with news about a WHOI vehicle that has been feared lost. "On Saturday, May 10, 2014, at 2 p.m. local time (10 p.m. Friday EDT), the hybrid remotely operated vehicle Nereus was confirmed lost at 9,990 meters (6.2 miles) depth in the Kermadec Trench northeast of New Zealand. The unmanned vehicle was working as part of a mission to explore the ocean's hadal region from 6,000 to nearly 11,000 meters deep. Scientists say a portion of it likely imploded under pressure as great as 16,000 pounds per square inch."
Where do you last remember seeing it?
They can look for the Deep Sea Vehicle and flight MH370 at the same time in that area. Very economical.

Maybe it defected. Is the protocol officer still alive?
We get so used to successful operations of these things that we forget how dangerous and harsh the environment is down at that depth.
Perhaps Wood's hole can fund another?
You linked to a wikipedia article on the game Battleship?
I've read the comments on three stories this morning. Anything remotely scientific is full of nothing but lame joke comments. The one about the sun is full of "my hot sister" comments. It's pathetic.
Got down to this comment on this story, and it's nothing but idiotic jokes.
The flipside is anything political. Those stories will get hundreds of comments with nothing but pointless bickering.
There is no useful discussion on this site anymore. I'd list some alternatives, but I don't want you ignorant fucks to ruin the others.

Agreed. Let's talk about planets in the solar system instead. The 7th from the Sun seems like an interesting one, don't you think?

You consider a story on the lose of a single submersible in an accident to be "remotely scientific," and you're calling the rest of *US* idiots?
SJW's don't eliminate discrimination. They just expropriate it for themselves.
The article said it had an optical fiber tether. Nothing on how strong the tether was, but I am assuming it was like breaking a fishing line, so no way to retrieve a portion of the device. They did say that they found pieces floating on surface though.
"He's lost in a 'floyd hole"
It's aliens hiding out in the deep. They will bring the submersible back once they are done studying it.
They should have tied a string to it.
It's just pining for the trenches.
Well, there's spam egg sausage and spam, that's not got much spam in it.
Years ago (not saying how many!) I worked with a university program specializing in autonomous underwater vehicles. Their designs made the submersibles nominally buoyant so that when they lost power they would eventually surface. For deep sea applications I'm sure it's more difficult.. If it were crushed, then I imagine all bets are off.
Bad fish. Not like going down the pond chasin' bluegills and tommycods. This shark, swallow you whole. Little shakin', little tenderizin', an' down you go... If you want to get your deep sea vehicle back, then ante up. I don't want no volunteers, I don't want no mates, there's just too many captains on this island. $10,000 for me by myself. For that you get the head, the tail, the whole damn thing.
They pretty much know where it is, they just can't get it back.
As opposed to MH370, which nobody knows where TF it is.
Agreed. Let's talk about planets in the solar system instead. The 7th from the Sun seems like an interesting one, don't you think?
So, when that one gets downgraded like Pluto did, will they call it a planetoid or an assteroid?
Thanks folks, I'll be here all week. Try the veal, tip your waitress.
He he, the button I need to click next says "sub-mit". He he.
For pushing the boundaries. There wouldn't have been an implosion if they weren't pushing it to the edge.
Some people just don't have an appetite for exploration anymore - I say "job well done."
My God, it's Full of Source!

The debris from a two ton ROV doesn't even begin to compare to the daily avalanche of crap we dump on the seafloor.
My father in law was a sonar operator aboard P3's in the 70's and 80's. The thousands of sonor buoys he dropped in the ocean would probably surprise you. They're designed to operate for a while and then, when the batteries are nearly dead, flood and sink to the sea floor so they can't be recovered and reversed engineered. There's a stretch of ocean bed in the north atlantic that must just be carpeted with the things.
Luckily the sea floor is a big place.
Put 1090 atmospheres or add 1125 Kg/cm^2... Not everyone is using an archaic unit system. Actually, only very few are...
Thank you,
Someone used the word "implosion" correctly.

It's also a very corrosive place.
Who in their right mind would make a deep sea research submarine out of wood, which has holes in it! I mean we are in the 21st century. We rarely make boats out of wood anymore, We defiantly don't make million dollar research devices out of wood, and if they did, they would use high quality wood, not ones with holes in it!
The holes are in it to keep the pressure equalized. Duh.
You've got a sister?

Those holes were an early version of Windows. Every once in a while, you'd see a Blue Sea of Death.

I visited the woods hole facility over the summer, and they truly run a top notch operation (keeping these vessels in one piece at that kind of pressure is insanely tricky - what they're doing is amazing). I'm really sorry to hear about this loss; I'm sure it's going to have a significant impact on important research they're doing.
You do know that they renamed it in 2620 to put an end to that joke....

I am by no means a submersible expert and I am curious as to what part of the sub imploded.
16,000 PSI might sound like a lot of pressure but in reality we use pressures close to that in hydraulic systems (10,000 PSI systems are quite common) and well over that in hydro-forming systems.
Would vacuuming and back filling the air spaces with a non conductive fluid such as Fluorinert or mineral oil be of any benefit? If you eliminate compressible gases from the design, nothing can implode. Weight could be an issue but the liquid can also help ballast the vehicle. The only spot that could be a problem is with motors but the stator coils could be sealed in a fluid or potted cavity and the armature/rotor could live outside under the external pressure and simply use magnetic coupling (like they do in fish tank filters). Maintenance would be a PITA but sounds like a worthy sacrifice to get something to safely handle those pressures.
Well, if it crossed the Pacific and went upstream the Columbia River, it might have made it to Montana -- although there are a surfeit of dams to overcome along the way.

No its not. http://news.discovery.com/hist... Named Halomonas titanicae the bacteria are eating our wreck's metal and leaving behind "rusticles," or icicle-like deposits of rust. The porous rusticles will eventually dissolve into fine powder. So most of those bouys will be consumed and meet the fate of the Titanic, dissolved to dust. So if there is bacteria eating iron there is ones eating sulfur and other chemicals as well.
... 11,000 meters deep... ...
Scientists say
... 16,000 pounds per square inch
Time to embrace the metric system, don't you think so ?
No its not.
Salt water under high pressure is not corrosive? You've never dealt with stuff underwater for very long, have you?

Which is what I'd call a corrosive environment.
to me corrosive meant battery acid level of dissolving human flesh. Not salt slowly dissolving things over a series of decades. So while it s a corrosive enviroment in the physical sense of the definition. What people think is corrosive the ocean is simply not. To most people corrosive is penny dropped into liquid and fizzing for a minute until dissolved. This is what I was saying no to. Not slow dissolve of the iron. So points for being pendantic, points taken way for not getting that people don't understand how salt interacts.
