James Cameron to spend several hours in Mariana Trench

Use caution.

While I suspect the smart money is on that being true, that seems to be a bit of risk to say. How much of that place has been photographed or looked at. We here all know about the famous 20 minutes in one small spot. How much else has been looked at with remote vehicles? Not very much I suspect. Yeah, harsh deserts are boring as hell too but there are the occasional spots of great interest.

I hope that Cameron lets some actual researchers use this thing (and funds it too) to get some significant “lets look around” time down there. You never really know until you take a good look around.

we prefer to use 1419 (Shire Reckoning).

And several more dives planned. I hope you’ve got all your fingers and toes ready Lobohan

But what year is this? And how long did he stay for?

I don’t get it. Did we need another thread on this topic?

I merged Lobohan’s thread into this one. Posts 54, 55, and 64-66 were originally part of that thread.

Yeah, I somehow missed this one. I thought I was being clever.

Little know fact. While Hobbits were sticklers for precision and tradition, due to their very cloudy climate their astronomy skills sucked. Because of that they had no idea that a leap day was needed every so often. These three facts lead to their demise. After many years their calendar was so far outa wack they were planting spring crops as winter was approaching. Eventully they all starved to death.

And now you know the rest of the story.

How did I know there was gonna be a hate thread here. :cool:

Damn you Cameron…Damn you to hell…:mad:

He probably read all those anti-Avatar threads in Cafe Society and decided he was going to spend a couple tens of millions to screw up our beloved meme.

If he kills Opal and goes back in time to show that 1920’s style death rays were actually ineffectual and generally kind of lame, we’ll know he’s out to get us.

But there’s still enough salt in the ocean to cover the moon knee-deep, right?

“But just wait till you see this shit in 3D! It’ll be like you’re watching actual mud!!!”

In particular, I was wondering how the Deepsea Challenger attains positive buoyancy. The bathyscape design of the old Trieste was dictated by the fact that a strong enough pressure hull was too thick and heavy to be positively buoyant, and so needed the large gasoline-filled container as a float. How does the new design work?

Yep, just the way lunar frogs like it.

I’m glad that somebody did this again and expected the scenery to be no more exciting than the Moon. Though the Moon did have that blue marble as a contrast to the grayness.

Having succeeded in the mission, I’d prefer that they went a little bit less deep next time and perhaps that would allow them to stay longer. Maybe just go six miles down next time. I curious about the sea animals that aren’t have a little less pressure and coldness to deal with and so are able to grow larger than the size of an aspirin. What I’d really like to see is an underwater space station that is manned long-term. It seems that we know less about what is five miles below us than what is a thousand miles above.

This is why I love the Dope.

When I saw this news article, the first thing I thought was “for how long, 20 minutes?” And I KNEW there would be a thread!

Thanks SDMB!

Everything you need to know about Deepsea Challenger’s construction, including why it’s buoyant.

Ah, syntactic foam. It’s been used on submersibles before but they had to invent a new kind that could take deep abyss pressures.

XKCD with a graphical interpretation of the depths…
Fun fact: The Edmund Fitzgerald, The Kursk and The Lusitania all sank In water shallower than they were long!
