saturation diving: Meaning and Definition of

satura'tion div"ing

Pronunciation: [key]
  1. a method of prolonged diving, using an underwater habitat to allow divers to remain in the high-pressure environment of the ocean depths long enough for their body tissues to become saturated with the inert components of the pressurized gas mixture that they breathe: when this condition is reached, the amount of time required for decompression remains the same, whether the dive lasts a day, a week, or a month.
