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.
