Table Definitions-1 Definitions Depth: Maximum depth attained during a dive Actual Bottom Time (ABT): Time from leaving surface until beginning a direct ascent to the surface Decompression: Process of eliminating nitrogen from the body during ascent – Linear: One continuous ascent without stopping – Staged: Stops for specific times at specific depths during ascent No-Decompression limits: Maximum time that can be spent at a given depth without requiring staged decompression
Table Definitions-2 Definitions Decompression schedule: List of decompression stops for a particular max. depth and bottom time, e. g., 100’/25 Single dive: Any dive conducted more than 12 hours after a previous dive Surface Interval Time (SIT): Time spent at the surface between dives. Residual nitrogen: Amount of nitrogen gas remaining in a diver’s tissues following a dive Repetitive dive: Any dive conducted less than 12 hours after a previous dive.
