Yes, you can breathe air in an air pocket - it's normal air. However, you will exhaust the oxygen supply quickly if the air pocket is small. I've tried to measure if deep enough underwater compressed air would have density > than one of water, which is virtually not compressible.
How long can you breathe in an air pocket underwater?
If the pressurized air pocket were about 216 cubic feet (6 cubic m), Umansky reckoned, it would contain enough oxygen to keep Okene alive for about two-and-a-half days, or 60 hours. But there is an additional danger: carbon dioxide (CO2), which is lethal to humans at concentrations of about 5 percent.
Why can't you breathe an air pocket?
In an air pocket, the first problem is carbon dioxide build-up. Every time you exhale within the bubble, you release toxic carbon dioxide into a closed space. When carbon dioxide levels reach 50,000 parts per million, you'll begin to feel sort of drunk.
Are underwater caves possible?
Underwater caves can be found around the world, but appear and develop differently according to their environment. Caves in warmer waters can be home to coral reefs, while ice caves have less abundant life. Photographers and divers have made it possible for us to get a glimpse at these mysterious underwater worlds.
Are there caves under the ocean?
Sea caves are found throughout the world, actively forming along present coastlines and as relict sea caves on former coastlines. Some of the largest wave-cut caves in the world are found on the coast of Norway, but are now 100 feet or more above present sea level.

Are there air pockets in the Titanic?

How do diving bells not fill with water?
The bell is ballasted so as to remain upright in the water and to be negatively buoyant, so that it will sink even when full of air.
How much do SAT divers get paid?

How deep can a submarine go?
It's generally accepted that the maximum depth (depth of implosion or collapse) is about 1.5 or 2 times deeper. The latest open literature says that a US Los Angeles-class test depth is 450m (1,500 ft), suggesting a maximum depth of 675–900m (2,250–3,000 ft).

Did they hear Titanic hit the ocean floor?
Humans have a very difficult time hearing in water, as our bodies are not meant to hear in that environment (sound does not travel the same via water as it does air), and being that the ship hit the bottom a long distance away, it is doubtful that any human ears would be able to pick up any sound from that depth.
Did Titanic survivors get money?
Many of the factors leading to the loss of life on board the ship were judged to have been unforeseeable. Hundreds of claimants had joined the suit, asking for more than $16 million in damages. In the end, the company paid a total settlement of $664,000 to be divided among them.

Can you scuba dive to the Titanic?
No, you cannot scuba dive to the Titanic. The Titanic lies in 12,500 feet of ice cold Atlantic ocean and the maximum depth a human can scuba dive is between 400 to 1000 feet because of water pressure. The increasing water pressure also restricts blood flow by constricting tissue.
