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 ...
The lower initial pressure at the surface means that a mass of gas occupying a given volume will be compressed more than the same volume at sea level for the same depth. The formula for Boyle's law applies: P 1 V 1 = P 2 V 2 or: V 2 = P 1 V 1 /P 2 or: V 2 /V 1 = P 1 /P 2. Example: At sea level P 1 = 1 bar (approximately), and at 10 m depth at ...
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.

When it comes to high blood pressure, the good news, according to the CDC, is that more and more adults over 60 are aware of the risks and are seeking treatment — but the risks themselves haven ...
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.
