Dive Terms

The NAUI terms - different than what I learned in NASDS

Note for computer users record only:

Acronyms:

  1. (A)MDT - (Adjusted) Maximum Dive Time
  2. ADT - Actual Dive Time
  3. D - Depth
  4. PD/PD+ - Precautionary Depth stop/+ means deep stop.
  5. RNT - Residual Nitrogen Time.
  6. SAC - Surface Air Consumption
  7. SIT - Surface Interval Time
  8. TNT - Total Nitrogen Time
  9. EAD - Equivalent Air Depth
  10. MOD - Maximum operating depth
  11. ATA - Atmospheres absolute (think French) 1 bar = .986923 atm OR 1 bar=1 atm, and 10 M = 1 ATM. ATA = Depth / 33 + 1.

Formulas:

  1. <<latex($Partial~Pressure = O_2 \% \cdot Depth_{ATA}$)>>

  2. Henry's Lay states: <<latex($Residual~Nitrogen \sim depth$)>>
