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 entire coast of California.Learn More
Experts use the results from our dives to improve the way we manage our natural resources. Reef Check programs provide ecologically sound and economically sustainable solutions to save our reefs. We create partnerships among community volunteers, government agencies, businesses, universities, and other nonprofits.
With divers who survey the health and status of coral reefs, the Tropical Program uses a globally standardized scientific protocol to collect valuable data for reef management. Our EcoDiver teams span 102 countries and territories to help preserve and protect our coral reefs.Learn More
The purpose of the Reef Check California Program is to educate, train, and engage our community to monitor the health of our kelp forests. Local citizen scientist divers volunteer their time to support science-based management and marine conservation.Learn More
Our Education Program is an engaging and interactive course that gives students the opportunity to experience a day as a marine biologist. We teach awareness of our ocean resources and aim to inspire a new class of citizen scientists.Learn More
Reef Check has coordinators, teams, and EcoDiver training facilities in countries around the world. Since the first Reef Check coral reef monitoring survey in 1997, our EcoDivers have completed over 14,000 surveys in 102 countries and territories. Our initiative is built on over 20 years of global reef health data.Learn More
The Octopus is a soft-bodied mollusk in the class Cephalopoda. Found in all the world’s oceans, there are almost 300 identified species. The word octopus comes from the Greek, októpus, which means "eight foot."
