How does the moon phase influence night dives?

• A. It determines the dive group size
• B. It affects natural lighting and animal behavior
• C. It has no significant effect
• D. It determines the safety of the dive

Answer: (B)

The influence of the moon phase during night dives primarily revolves around how it affects natural lighting and animal behavior. The brightness of the night sky can vary significantly depending on the lunar cycle. During a full moon, for instance, there is increased natural light, which can enhance visibility underwater and allow divers to see more of their surroundings, including flora and fauna. Conversely, during a new moon, the absence of moonlight can lead to darker conditions that may limit visibility and necessitate additional lighting equipment, such as dive lights, for safety and navigation. The moon’s phase also influences marine life behavior; some species may be more active during certain phases due to changes in feeding patterns linked to the presence or absence of light, which divers can observe during their night dives. By understanding the relationship between moon phases and their effects on lighting and animal activity, divers can better plan their dives for optimal experiences and safety.
