What does the term "mission" refer to in diving context?

In the context of diving, the term "mission" encompasses the concept of a single dive as well as a series of repetitive dives. This understanding is critical because divers may undertake a mission with specific objectives, which can include multiple dives aimed at achieving a particular goal, such as scientific research, underwater exploration, or training exercises. By recognizing a mission as both a singular event and a broader set of activities, divers can better plan and execute their diving operations, ensuring proper consideration of all factors like safety, gas management, and environmental conditions during both individual and subsequent dives.
