As a diving expert with extensive knowledge in underwater exploration and safety, I can provide you with a detailed understanding of how deep a diver can go without being crushed, which is fundamentally tied to the principles of pressure and decompression.
Pressure in the Ocean
The ocean exerts pressure on divers due to the weight of the water above them. This pressure increases linearly with depth, approximately by 1 atmosphere for every 10 meters (or 33 feet) of descent. At sea level, the atmospheric pressure is about 1 atmosphere, which is equivalent to 14.7 pounds per square inch (psi) or 1013.25 millibars. As a diver descends, this pressure increases, and so does the pressure on the diver's body.
**The Human Body's Response to Pressure**
The human body is not designed to withstand extreme pressure. However, it can adapt to increased pressure to a certain extent. The body's tissues can be compressed, and the gases in the body (primarily nitrogen and oxygen from breathing) can be absorbed and dissolved into the bloodstream and tissues. This is why divers breathe compressed air or other gas mixtures that are designed to maintain a balance with the surrounding water pressure.
Decompression and the Role of Nitrogen
One of the critical factors in deep diving is the need to manage nitrogen absorption and the subsequent decompression process. Nitrogen is highly soluble in blood lipids and can be absorbed rapidly at depth. However, as a diver ascends, the pressure decreases, and nitrogen can come out of solution too quickly, forming bubbles in the bloodstream and tissues, a condition known as decompression sickness (DCS), commonly referred to as "the bends."
Decompression Stops
To prevent DCS, divers must make decompression stops during their ascent. These stops allow the body to off-gas nitrogen gradually, reducing the risk of bubble formation. The need for decompression stops increases with depth. As you mentioned, a diver at 6 meters (20 feet) can dive for many hours without needing to make decompression stops, as the pressure is not high enough to pose a significant risk of nitrogen saturation. However, at depths greater than 40 meters (130 feet), the time a diver can spend at the deepest part of the dive before needing to make decompression stops is significantly reduced, often to just a few minutes.
Depth Limits and Dive Planning
Dive planning is crucial for safety. Recreational divers typically do not exceed depths of 40 meters (130 feet) without specialized training and equipment. Technical divers, with proper training and using gas mixtures like trimix or heliox, can go deeper, but they must adhere to strict dive profiles and decompression schedules. The maximum operating depth for recreational divers using air is around 30 meters (100 feet), beyond which the risk of DCS increases significantly.
The Role of Equipment and Training
Proper equipment and training play a vital role in deep diving. Divers must use equipment designed for the depths they intend to reach and must be trained in the use of this equipment. Training also includes understanding dive tables, dive computers, and the physiological effects of diving at depth.
Conclusion
In conclusion, the depth a diver can safely reach without being crushed is determined by a combination of factors including the pressure at depth, the body's ability to tolerate increased pressure, the management of nitrogen absorption and off-gassing, and the use of proper equipment and training. Divers must always plan their dives carefully, considering the depth, duration, and necessary decompression stops to ensure a safe and enjoyable underwater experience.

The need to do decompression stops increases with depth. A diver at 6 metres (20 ft) may be able to dive for many hours without needing to do decompression stops. At depths greater than 40 metres (130 ft), a diver may have only a few minutes at the deepest part of the dive before decompression stops are needed.
