Table 2 Overview
Table 2: Surface Interval Time
As you learned during the previous lesson, the amount of residual nitrogen in your body is represented by a letter group. A higher letter group indicates you have a higher amount of nitrogen in your system, and a lower letter group indicates a lower amount.
You offgas nitrogen during your surface interval, so your letter group will change as well. To determine your new letter group following a surface interval, you use Table 2.
The letter groups at the top of Table 2 are your end-of-dive letter groups from Table 1. The cells below those letter groups contain time spans in hours and minutes. The letter groups at the left side of the table are the new letter groups following the surface interval.
