Question: 1 / 400

What does the term "surface interval" mean?

The time spent at the surface before a dive

The rest period during a dive

The time spent at the surface between two scuba dives

The term "surface interval" refers to the time spent at the surface between two scuba dives. This period is crucial for divers as it allows the body to eliminate nitrogen that has been absorbed during the previous dive. Proper management of surface intervals plays a significant role in reducing the risk of decompression sickness. During this interval, divers can rest, hydrate, and prepare for their next dive, ensuring they are in optimal condition.

Recognizing the importance of surface intervals can also aid in planning dive schedules and understanding the science of how nitrogen levels change in the body with varying depths and exposure times.
