Reef Check empowers people to save our reefs and oceans. Let’s work together to create a sustainable future through education, research, and conservation. Join us in our mission. We’re a team!
Every year, we train thousands of citizen scientist volunteers to survey the health of tropical coral reefs around the world and kelp forest ecosystems along the West Coast of North America.

Our initiative is built on over 25 years of global reef health data.
