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 cylinder 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.
