Reef Check Liveaboard Safari- Philippines

Reef-Check-EcoReef Check founder Dr. Gregor Hodgson will be your host for this 6-night liveaboard safari in the Southern Visayas, Philippines. Take the FREE Eco-Diver certification course and you can begin to monitor and survey the reefs of the region.

During the trip you will have the opportunity to learn how to scientifically survey a coral reef using the global standard Reef Check technique. Greg teaches how to monitor coral reefs by using a set of 30 predefined indicators and as Reef Check is a non-profit organisation, all materials will be provided by the Siren Fleet. Upon successful completion of the course you will receive a certification card allowing you to participate in future Reef Check survey expeditions anywhere in the Indo Pacific.
