Methodology
How we picked these locations
We use the sighting-occurrence-cluster methodology: encounter regions are ranked from primary to closed based on documented occurrence records, operator continuity, and regulator permit status. We never publish per-trip sighting probabilities — “best” here means the most reliably documented region for this encounter, not a guarantee.
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 We deliberately do not publish a numeric '% chance of sighting' from this data.
Timing shifts with water temperature and prey distribution. Confidence is medium; encounter is occurrence-clustered, not survey-measured.
