This is the period at surface between dives. The nitrogen that is collected in the body at the first diving is drained through breathing during surface slowly into the outside of the body.
<Table 2> "A" of the surface of Surface Interval Time Table
is Nitrogen Disappearance Time.
Nitrogen Disappearance Time is the time that is not enough time for us to drain nitrogen from our body completely.But, nitrogen is drained from our body to the level that does not influence the next diving.
Therefore, you are able to use <Table 1> Bottom Time – Residual Group
Table for next diving in the same way as the first diving if Surface Interval
Time exceed Nitrogen Disappearance Time of "A".
Conversely, if Surface Interval Time does not exceed Nitrogen Disappearance Time of "A", the next diving is called repetitive diving.
For repetitive diving, pay attention to residual. |
