The minimum surface interval recommended between two dives is _____

The recommended minimum surface interval between two dives is often guided by the necessity to allow nitrogen, which is absorbed into the body during diving, to dissipate safely from the system. A surface interval of at least 10 minutes is generally advised for recreational divers to help reduce the risk of decompression sickness. This time allows the body to off-gas nitrogen that was taken up during the first dive, especially if the first dive was to significant depths or involved prolonged exposure.

While shorter surface intervals may not effectively clear nitrogen from the system, a 10-minute interval provides a baseline that is considered adequate for many diving scenarios. It's essential for divers to plan their dives with sufficient surface intervals to ensure a safer diving experience, particularly if subsequent dives involve deeper depths or longer bottom times.
