Dive series A group of repetitive dives between which the Spyder indicates
some nitrogen loading is present.
Dive time Elapsed time between leaving the surface to descend, and re-
turning to the surface at the end of a dive.
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.
Multi-level dive A single or repetitive dive that includes time spent at various
depths and whose no-decompression limits are not determined
solely by the maximum depth attained.
No-decompression time
The maximum amount of time a diver may remain at a particu-
lar depth without having to make decompression stops or re-
main below a ceiling 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.
Repetitive dive Any dive whose no-decompression time limits are affected by
residual nitrogen absorbed during previous dives.
