What is one of the responsibilities of the dive supervisor during a decompression dive?

The responsibility of controlling the timing of decompression stops is crucial for the safety and effectiveness of a decompression dive. During such dives, divers experience changes in pressure that can affect their bodies, particularly with regard to the absorption and release of gases like nitrogen. Properly managing the timing of decompression stops is essential to prevent decompression sickness, commonly known as "the bends."

The dive supervisor must ensure that each decompression stop is adhered to for the correct duration as outlined in the diving tables or dive computer readings. This careful timing allows for a gradual ascent, which helps gases safely exit the diver’s body. Skipping or shortening these stops can lead to serious health risks. Thus, this responsibility is pivotal in maintaining diver safety during and after the dive.

While monitoring equipment, directing longer stops, and communication among divers are important aspects of dive operations, none are as critical as the precise management of decompression stops to mitigate the risks associated with rapid pressure changes.
