Sources & methodology
How we summarise this
We aggregate confirmed occurrence records from GBIF and OBIS within a fixed radius of each dive site. Occurrence records confirm presence and reveal seasonality clustering, but they DO NOT measure per-dive probability — there is no eligible-effort denominator. We deliberately do not publish a numeric '% chance of sighting' from this data.

Gear for this site
Beyond the basic kit- Coldwater wetsuit + hood — Humboldt upwellings drop temp to 19°C in season — third dive of the day is the cold one.
- Reef hook — Hooking is the only way to hold the line while hammerheads pass.
- Nautilus Lifeline or PLB — Surface separations have happened here. PLB is standard kit.
