A diving chamber is a vessel for human occupation, which may have an entrance that can be sealed to hold an internal pressure significantly higher than ambient pressure, a pressurised gas system to control the internal pressure, and a supply of breathing gas for the occupants. [1] There are two main functions for diving chambers:
A deck decompression chamber (DDC), or double-lock chamber is a two compartment pressure vessel for human occupation which has sufficient space in the main chamber for two or more occupants, and a forechamber which can allow a person to be pressurised or decompressed while the main chamber remains under constant pressure.
A diving bell is a rigid chamber used to transport divers from the surface to depth and back in open water, usually for the purpose of performing underwater work. The most common types are the open-bottomed wet bell and the closed bell, which can maintain an internal pressure greater than the external ambient. [1]
Saturation diving is normally done from a saturation system on a diving support vessel or an offshore platform.While under saturation, the divers cannot be decompressed quickly in response to an emergency as that would be rapidly fatal, and though unusual, emergencies requiring personnel evacuation have occurred on such platforms due to extreme weather or accidents.
Submerged chambers provide dry areas for work and rest without the need to ascend to the surface. [6] This kind of submerged chamber uses the same principles as the diving bell, except they are fixed to the seafloor and may be called a wet porch, wet room, or wet bell. Sometimes the term moon pool is used to mean the complete chamber, not just ...

Deep diving is underwater diving to a depth beyond the norm accepted by the associated community. In some cases this is a prescribed limit established by an authority, while in others it is associated with a level of certification or training, and it may vary depending on whether the diving is recreational , technical or commercial .
The WDHOF awards many scholarships and training grants [11] to support women of "all ages who are pursuing careers involving diving" [12] including the J. Berman Memorial Grant for Sea Turtle Conservation, the Sherry Reed Memorial Undergraduate Marine Conservation Scholarship, the Laurel Clark Sea to Space Physiology Research Grant and the Amelia Behrens-Furniss Memorial Hardhat Dive Training ...
