Surface Interval
A Surface Interval is the necessary rest period that divers must take between dives to ensure safety. Think of it like a mandatory break time that helps the body release excess nitrogen that builds up during diving. For diving instructors and professionals, managing surface intervals is a critical safety skill, similar to how a bus driver needs to take required breaks between shifts. When reviewing resumes in the diving industry, this term indicates that the candidate understands and prioritizes diving safety protocols.
