Scuba divers thought they rarely touched reefs. Observers found damage
A new study reveals that recreational scuba divers frequently cause damage to coral reefs, with over 40% of physical contacts resulting in harm. Despite high self-assessments of their diving skills, many participants remained unaware of the collisions they caused.
Why it matters
This research highlights a significant conservation challenge for marine ecotourism, suggesting that current diver education may be insufficient to protect fragile ecosystems.
Most scuba divers believe they rarely touch fragile seabed ecosystems, yet underwater observers tracking hundreds of tourists found that more than 40 per cent of their physical contacts caused visible damage to living coral structures.Research published in The Conversation by marine scientists and dive professionals revealed that recreational divers make physical contact with the reef an average of once every four minutes. When surveyed immediately after returning to the boat, those same divers underestimated their actual contact frequency by almost fivefold, with many remaining completely unaware of the collisions they had caused.The researchers spent hundreds of hours following, observing, and surveying 732 recreational scuba divers across world-famous marine destinations in Indonesia and the Philippines.
