Dive Terms
The NAUI terms - different than what I learned in NASDS
Note for computer users record only:
- SIT,
- Depth,
- Safety Stop
- ADT
Acronyms:
- (A)MDT - (Adjusted) Maximum Dive Time
- ADT - Actual Dive Time
- D - Depth
- PD/PD+ - Precautionary Depth stop/+ means deep stop.
- RNT - Residual Nitrogen Time.
- SAC - Surface Air Consumption
- SIT - Surface Interval Time
- TNT - Total Nitrogen Time

- EAD - Equivalent Air Depth
MOD - Maximum operating depth solves equation 1 below for Depth, Best Mix would give a depth and solve for <<latex($O_{2}\%$)>>.
- ATA - Atmospheres absolute (think French) 1 bar = .986923 atm OR 1 bar=1 atm, and 10 M = 1 ATM. ATA = Depth / 33 + 1.
- CNS - Central Nervous system oxygen toxicity.
Formulas:
<<latex($Partial~Pressure = O_{2}\% \cdot Depth_{ATA}$)>>
Henry's Lay states: <<latex($Residual~Nitrogen \sim depth$)>> That is, the level of in-gassing you will incur is directly proportional to your depth.
