Full Disclosure....

...so if you find the air bubble in the bow section of the Avalon wreak, it was me who put it there. What started out as a “test” to see what would happen has become quite successful.

On a recent dive, I emptied most of a pony bottle into the hull only to realize the air was not escaping. I have made a number of quick dives since using my 30CF and 40CF pony and stage bottles which has allowed me to empty my 100CF and 120CF tanks to fill the bow.

Obviously normal cave diving protocol – You should not breathe the gas bubble! Following the initial dive, I did ”smell” the air – Smells like rusty steel and the ocean.
I ran into some leaks and I have used silicon sealant from the inside out which means now the bubble smells like silicon 8(

So help me out –
1. If you have 50CF to spare, can you leave them in the bubble?
2. Any ideas how to improve the smell of the air to remove the silicon smell??

Ps. My dive buddy wants no part of this crazy experiment but I think its so cool having a room to use at 65’!

Unless you build a water and pressure proof forced air CO2 scrubber to remove any CO2 you breath out into the bubble, you are going to pass out in that bubble. Not a very cool room at 65'.

Also, even if you don't inhale or frequent the location, the rust process will remove the oxygen from the air pocket and can reduce it below the 16% concentration needed to support life.

Now to remove the silicon smell would require forced ventalation of the gasses in the void. The "silicon" smell is the solvents in the material evaporating out into the air to allow the calking to solidify. Sorry but you are stuck with the smell, unless you can carry anough gas down to force the existing gas out with the solvents. Next time use splash zone epoxy, its a chemical reaction that might not release noxious fumes.

By teh way, what is the point of your "experiment"?

Mud, you might want to note the date

Troll, moron, April 1 - what ever!

Might actually be a good discussion.

Good answer, though!

Sweet avatar! What ventage would that be?
