Shoot, anybody could climb that! I'd rate it a UW6 (Under-Water-Six) at best. 
Figuring buoyancy, does that mean that flatter terrain is theoretically harder? All things fair, the less fit people, "blubbery" in UW terminology, would have a harder time staying attached to the 'wall' the flatter it gets.
Here's my new rating system and estimated related steepness:
-- Roofs to -45° = UW0, UW1, UW3
-- -45° to Vertical = UW4, UW5, UW6
-- Vertical to +45° = UW7, UW8, UW9
-- +45° to +22.5° = UW10a,b,c,d, UW11a,b,c,d
-- +22.5° to Flat-bottom = UW12,a,b,c,d
Oh, "he's holding his breath," you say... Oh, Oooohhhhhhhhhhhh.

My buddy and I were debating if this was real. He went almost to the "no limits diving" record depth according to his claims. No limit diving typically involves riding a weighted cart down, and a balloon back to the surface. According to wikipedia, the record is 214m. How did he almost match this record without using the tricks and even wasting time at the rim before jumping and at the bottom posing? Anyone know more about this, I'm actually curious? Also, if his videographer was female, she beat the female "no limit diving" record by almost 150' on this same dive. Just find that hard to believe....
Here's another source:

Wikipedia link on free-diving, scroll to the bottom for records:

Thanks man, I think that update on the huffington post page is since I last looked at it. :) That explains a lot. It didn't look like he was moving fast enough to go that deep. Cool video!

Can you please give the UW to V-scale to YDS conversion for this?  Thanks.. .

When I first saw that on the MSN home page I thought it looked lame. Now I can see that I was correct.

V and YDS doesn't convert directly cuz this was UNDER WATER, geez!!!1!
n00b!
Ok, fine, if we have to make some sort of estimate. UW12 would be like down-soloing The Nose with your overweight mom riding piggy-back while breathing through a coffee swizzle stick.

Absolutely. However, also notice the poor use of footwork.

I guess you guys didn't read the description,
In reply to: FREE FALL: World champion freediver Guillaume Nery special dive at Dean's Blue Hole, the deepest blue hole in the world filmed entirely on breath hold by the french champion Julie Gautier. This video is a FICTION and an ARTISTIC PROJECT. Edited by BLUENERY (c). Music: ARCHIVE - you make me feel. |

Enjoy the video, darkgift!
Here's a spoiler: He actually is a champion freediver. Also, the only reason it's branded as fictional is that he didn't actually touch the bottom.
At a certain point, I think the body stops floating so he had to climb. Can someone correct me if I'm wrong? Physics was not my forte.

Wrong. Yesterday it didn't say fictional or artistic.

I haven't taken a proper physics class, but I don't think it works quite like that; boyancy is derived from displaced water weight verses your weight, assuming you're lighter than the displaced water. Thus at greater depths, the water is more compressed so you're displacing a greater weight of water i.e greater boyancy.
The reason he's climbing i think is because he has a ton of lead weights on.

Actually, I'm pretty sure that there is a depth with a weighted suit that you become neutrally buoyant depending on the amount of air in your lungs.

Having done a lot of free-diving and scuba diving, I can tell you this is basically true. You have air spaces in your body and wetsuit (and tanks if you're using them). At a certain depth, those airspaces are compressed, your buoyancy is equal to the weight pulling you down, and you are neutrally buoyant. Above that depth, that buoyancy is dominant (compared to your weight) and you are positively buoyant. Below that depth, your weight takes over and you become negatively buoyant, i.e the deeper you go, the faster you sink. I may not be able to explain the physics of it, but I can tell you this is how it works.
ah, thanks. Mine was just wild speculation w/8th grade physics.
So would that imply that you weight more than the water you displace due to compression, or is it more complicated than that?

Yes from a physical point of view then that must be correct if what csproul is true. (which I have no reason to doubt)
Your body is mostly neutrally buoyant. Your bones, teeth, nails are a fair bit heavier than water. Muscle, hair and skin weigh slightly more than water. Fat slightly less. Most of it would roughly cancel out. Air in you lungs, mouth, throat are the main source of positive buoyancy. As pressure increases the air compression and your body's volume and thus its buoyancy increases. Water is largely incompressible so the density is barely dependent on depth. (Temperature makes makes a bigger difference.)
