The outside water pressure increases with depth and so the stresses on the hull also increase with depth. Each 10 metres (33 ft) of depth puts another atmosphere (1 bar, 14.7 psi, 101 kPa) of pressure on the hull, so at 300 metres (1,000 ft), the hull is withstanding thirty standard atmospheres (30 bar; 440 psi; 3,000 kPa) of water pressure.
So the 1 atmosphere or bar contributed by the air is subtracted to give the pressure due to the depth of water. The pressure produced by depth in water, is converted to pressure in feet sea water (fsw) or metres sea water (msw) by multiplying with the appropriate conversion factor, 33 fsw per atm, or 10 msw per bar. In feet
A dive profile is a description of a diver's pressure exposure over time. It may be as simple as just a depth and time pair, as in: "sixty for twenty," (a bottom time of 20 minutes at a depth of 60 feet) or as complex as a second by second graphical representation of depth and time recorded by a personal dive computer. Several common types of ...
60 m (200 ft) Depth limit for a group of 2 to 3 French Level 3 recreational divers, breathing air. [17] 66 m (217 ft) Depth at which breathing compressed air exposes the diver to an oxygen partial pressure of 1.6 bar (23 psi). Greater depth is considered to expose the diver to an unacceptable risk of oxygen toxicity. [nb 2] 100 m (330 ft)
As of 1990, ascent rates used in tables and dive computers ranged from constant ascent rates of 33, 40, and 60 fpm, from all depths, to variable depth dependent rates of 60 fpm for depths below 100 ft, 40 fpm for depths between 100 and 60 ft, and 20 fpm for depths less than 60 ft in the ORCA dive computers.

A descent of 10 metres (33 feet) in water increases the ambient pressure by an amount approximately equal to the pressure of the atmosphere at sea level. So, a descent from the surface to 10 metres (33 feet) underwater results in a doubling of the pressure on the diver. This pressure change will reduce the volume of a gas filled space by half.
The 60-year-old, whose real name is Darren Taylor, attempted to dive from very high up into a very shallow pool. “I'm gonna do a belly flop into 10 inches of water from 26 feet, 6 inches for a ...
