This year, we are celebrating the 30th anniversary of the REEF Volunteer Fish Survey Project (VFSP). Since its launch in the Florida Keys in 1993, this citizen science program has grown into a worldwide effort, generating one of the largest ocean databases in the world through marine life surveys. REEF surveys have been conducted at more than 15,000 sites throughout the world’s oceans, by over 16,000 volunteer divers and snorkelers worldwide.

Having access to information about our oceans is increasingly important for conservation, especially in today's ever-changing marine environment. REEF volunteers make valuable contributions to science by conducting surveys to monitor fish populations, providing valuable insight into the health and biodiversity of our oceans. Scientists, government agencies, and conservation organizations use REEF data for research, resource management, and education. We're thrilled to be celebrating 30 years of this amazing citizen science effort, and members like you make it all possible.

Become a Citizen Scientist: It's easy to get started conducting REEF surveys, and both divers and snorkelers can participate. The only materials you need are an underwater slate and pencil, a good reference book, and access to the Internet to submit the data online. REEF has educational materials to help you learn along the way. Check out for more information.
