Isla Guadalupe White Shark Episode

[milkmood]

Aaron said he was six hours underwater in the cage on the last day of diving. I know there was surface-supplied air, so tank changes weren't an issue.

So, this leads me to some questions:

How deep was the cage to be able to stay underwater that long?

Was that all at one time, six hours straight?

Is the math and physics of air pressure, nitrogen absorption, safety stops, etc., different with surface-supplied air?

How does all that work on a unique dive boat like that one?


Love the show, by the way. Drinking and leering? Bah. If that stuff offends you...you better not watch this: Drinking Made Easy

Of course, with enough footage that stuff can be weaned down in the editing room.

I worked on one of the liveaboards running Guadalupe White Shark trips in 2007. Most cages hang off the back of the liveaboard vessels at about 6ft or so deep, many have a crane arm or winch system giving them the ability to lower a cage to 15-20 ft, and recently I think one of the permitted vessels can now lower a cage about to 30ft. Air NDL for up to 35 ft is over 3 hours. Usually divers rotate in and out of cages every hour. I'm sure he came up for surface intervals including food & hydration breaks, for warmth (even in a drysuit for potty breaks), to switch out camera & strobe batteries and get more recording media as well as to switch to another cage's vantage point before going back down. This what folks like Marty Snyderman, Andy Brandy Casagrande (NatGeo), Lance Milbrand, Paul Atkins, and Bob Talbot did while on board. It was awesome (and a priveledge) to watch them in action.

That said, if you haven't been to see the GWS at Guadalupe, it is definitely one of those bucket list dives. More awe inspiring in person than anything you can see on video, even on 3D IMAX.



Here's one of my pics.

Awesome, killer, fantastic first-hand-experience reply! Thank you very, very much.

I love this board more and more every day.

Added to bucket list.

Ciao.

Mike, you are welcome. Here's a couple more shots for you.

Here's one of my pics.

Nautilus Explorer drops four cages. Two on the surface, one at 15 ft (I think) and the other at 40 ft. They rotate people every half hour. I've heard that by the third day, the 'weaklings' are weeded out and you can get more time in the deeper cages if you want. They say on their site that the most time spent in the cages is 31.5 hours over the course of five days. In August, I'm fixin' to break that record. YEAH, BABY !!!

Dahhhh on a work computer and it wouldn't let me see the pic...

Anywayz - Okay, I know this is an into the drink forum, but is there much difference between Guadalupe and the Falloron Islands?

Sorry for the Hijack, if that truely is the case here.

The top three places in the world for G.W.S. sightings are supposed to be Australia, South Africa and Guadalupe. I don't think the Farralons have the consistency of sightings as the others.

Now that makes sense... no sightings, no business...

Another cool thing. On the Nautilus Explorer, non-divers (un-certified) can make three 'dives' a day in the surface cages. You must be certified for the deep cages.

Is it true that if you punch a shark on its nose it will swim away? Will this work on Great White Sharks?
