What does the "Stop" column in a dive profile indicate?

The "Stop" column in a dive profile indicates the required time spent at each depth during a dive. This is vital for safe ascent and managing decompression, as it helps divers avoid the risk of decompression sickness. When a diver ascends, they may need to spend specific periods at certain depths to allow excess nitrogen absorbed in the body's tissues to safely dissipate. This controlled ascent, including designated stops, is essential for reducing the likelihood of bubbles forming in the tissues.

Understanding this column is crucial for divers because it guides them on how long to pause at specific depths before continuing to ascend to the surface. Each depth may have different recommended stop times depending on the dive profile, dive duration, and the depths reached. This systematic approach to ascent is an essential part of diving safety practices outlined in training courses like SSI.
