After completing an ocean dive to 95 feet and a surface interval of 2 hours and 35 minutes, what is the adjusted maximum dive time for the following dive to 70 feet?

To determine the adjusted maximum dive time for a dive to 70 feet after completing a previous dive to 95 feet with a surface interval of 2 hours and 35 minutes, it is essential to consider both the no-decompression limits for the specific depths and the effects of the residual nitrogen from the first dive.

When a diver completes a dive, they accumulate nitrogen in their body due to the increased pressure at depth. After surfacing, the body starts to off-gas, but this process varies based on the surface interval. The longer the surface interval, the more nitrogen can be eliminated, which can influence the maximum allowable time for the next dive.

For a dive to 70 feet, the no-decompression limits in typical recreational diving tables indicate how long a diver can remain at that depth without requiring a decompression stop during ascent. Given the specifics of a 2-hour and 35-minute surface interval, divers would reference the tables or dive computers to see how this time affects their remaining allowable dive time, which in this case results in 33 minutes as the adjusted maximum dive time.

This conclusion highlights the importance of understanding dive tables and the nitrogen absorption and elimination process to ensure safe diving practices.
