Saturation diver working on the USS Monitor wreck at 70 m (230 ft) depth Saturation diver conducting deep-sea salvage operations. Saturation diving is diving for periods long enough to bring all tissues into equilibrium with the partial pressures of the inert components of the breathing gas used.
A "no-stop dive", also commonly but inaccurately referred to as a "no-decompression" dive is a dive that needs no decompression stops during the ascent according to the chosen algorithm or tables, [14] and relies on a controlled ascent rate for the elimination of excess inert gases. In effect, the diver is doing continuous decompression during ...
A no-decompression dive, or more accurately, a dive with no-stop decompression, relies on limiting the ascent rate for avoidance of excessive bubble formation in the fastest tissues. The elapsed time at surface pressure immediately after a dive is also an important part of decompression and can be thought of as the last decompression stop of a ...
In the CMAS International Diver Training Standards and Procedures Manual, CMAS states that "A one-star diver shall be deemed to have sufficient knowledge, skill and experience to procure air, equipment, and other diving services and to plan, conduct, and log open-water dives that do not require mandatory in-water decompression stops, without the supervision of a CMAS instructor or CMAS dive ...

[3] The then President of the University of California, Robert Gordon Sproul, restricted diving to those who had been trained through the program at SIO and thus "certification" was born.
