Dive series A group of repetitive dives between which the dive computer
indicates some nitrogen loading is present. When nitrogen
loading reaches zero the dive computer deactivates.
Dive time Elapsed time between leaving the surface to descend, and
returning to the surface at the end of a dive.
∆P
Delta P, describing the Cylinder Pressure drop during the
dive; difference in tank pressure between beginning and end
of dive.
EAD Abbreviation for equivalent air depth.
EAN Abbreviation for enriched air nitrox.
Enriched Air Nitrox Also called Nitrox or Enriched Air = EANx. Air that has some
oxygen added. Standard mixes are EAN32 (NOAA Nitrox I =
NN I) and EAN36 (NOAA Nitrox II = NN II).
Equivalent Air Depth Nitrogen partial pressure equivalent table.
Floor The deepest depth during a decompression stop dive at which
decompression takes place.
Half-time After a change in ambient pressure, the amount of time required
for the partial pressure of nitrogen in a theoretical compartment
to go half-way from its previous value to saturation at the new
ambient pressure.
HP Abbreviation for high pressure (= cylinder pressure).
Multi-level dive A single or repetitive dive that includes time spent at various
depths and whose no-decompression limits are therefore not
determined solely by the maximum depth attained.
NITROX In sports diving refers to any mix with a higher fraction of
oxygen than standard air.
NOAA United States National Oceanic and Atmospheric
Administration.
No-decompression time
The maximum amount of time a diver may remain at a particular
depth without having to make decompression stops during the
subsequent ascent.
No-decompression dive
Any dive which permits a direct, uninterrupted ascent to the
surface at any time.
NO DEC TIME Abbreviation for no-decompression time limit.
OEA = EAN = EANx Abbreviation for Oxygen Enriched Air Nitrox.
OLF Abbreviation for Oxygen Limit Fraction.
