Well he's on his way.

Film maker begins deep ocean dive

Film director James Cameron has begun an attempt to become the first person in 50 years to visit the deepest part of the ocean.

Cameron is travelling 11km (7 miles) down to the Mariana Trench in the western Pacific, where he hopes to spend six hours exploring and filming.

He is making the dive in a specially designed and cramped one-man submarine, the Deepsea Challenger.

So how long is descent? And when will he be back. I assume the 6hrs is on the ocean bottom?

Latest on the site says it should take about 2 hours to descend. Based on time zones I think that should be around 22:15 here.
 
James Cameron ‏ @JimCameron

Just arrived at the ocean's deepest pt. Hitting bottom never felt so good. Can't wait to share what I'm seeing w/ you @DeepChallenge

From 30 mins ago.
 
This is the coolest thing and the real shame is that he's only the 3rd person Ever to do it and there's no real publicity about it (only found out due to this post!)
 
two went down in the first dive d walsh and j picard

cameron is no3 to touch down as it were ..

the water pressure increases at roughly .52 psi/ft varies on the temp tho but if u say 1/2 of a psi/ft (btw same as your head pressure on pumps)

still a hell of a lot at 35,768 feet i guess as a roughie approx 18,600 psi

a lot diferent than the old stuff i used to work with all those years ago

i worked on these babies a long long time ago for intersub and swire pacific

well 13 people stpeed on the moon i think it was and its still a race to get commercial flights ... only 3 been to the challenger deep so there was a race to get there solo as it were
 
to put the pressure in another way. Atmospheric pressure at sea level ~1bar (weather maps display mbar 1000=1bar).

If you dive down to just 10metres that doubles to 2 bar, for every 10metres further you go down pressure increase by 1 bar, compare that to space where the difference the space shuttle has to contend with which is ~0 bar so that 1 bar difference. Crazy.

The trieste (sp?) was brilliant used petrol as flotation because air would be too hard to contain in the correct volume and the 3" viewing glass window cracked at around 3.5 -4km down still around 3 times the depth to go and he didnt bottle it.

Total crack pot but imo greatest extreme expedition since the first polar explorations
 
yes it was an amzing feat the funny thing is people look at the trieste and see a "sub" in the traditional sense but the manned portion was the sphere suspended underneath ..

as far as pressure is concerned tho atmospheric pressure per bar is 14.3 psi give or take dependant on temperature

1 Water Column [inch] = 0.0024583161485 atmosphere [standard] lolz that was taken from tables not of top of head btw
 
damn did he do it awesome ...... i missed it will have to troll the video threads and see what info is there..

should say damn i missed it i guess not damn did he do it..... wonder what the next movie will be....
 
I really wish we could just remove all the water from the planet temporarily and take a good look at the seafloor, I'd wager we would find all manner of wonderous things. The archaeology alone would be incredible, not to mention the natural discoveries.
