What to know about Divers may think they protect reefs, but one unseen habit is taking a steady toll

Research from the University of Sydney indicates that scuba-diving tourism causes significant, often unintentional, damage to coral reefs. The study highlights a gap between divers' perceived skill levels and their actual impact, suggesting that improved training and industry standards are necessary to protect marine ecosystems.

Why it matters

Bing Lin from the University of Sydney's Thriving Oceans Research Hub in the School of Geosciences, analyzed the behavior of more than 700 scuba divers across tourism hotspots in the Philippines and Indonesia, including Bali.

Common ground

Drawing on data from more than 300 hours of underwater observation, the researchers recorded 4,981 reef contact events among 411 divers.

Claim 1: “On average, divers made 0.26 reef contacts a minute—roughly one every four minutes—and spent nearly two seconds of every minute in direct contact with the reef.”
SINGLE SOURCE
While the claim appears in one web search result ('Scuba Divers May Be Damaging Coral Reefs...'), the other provided evidence for this index consists of irrelevant resort descriptions and Wikipedia definitions of divers. Only one relevant source confirms the specific stats (0.26 contacts/min).
