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 com-
puter deactivates.
Dive time
Elapsed time between leaving the surface to descend,
and returning to the surface at the end of a 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 pre-
vious value to saturation at the new ambient 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 frac-
tion 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 decom-
pression 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.
OTU
Abbreviation for Oxygen Tolerance Unit.
Oxygen Tolerance Unit
Is used to measure the Whole-Body-Toxicity.
