What Reef Check Foundation does

Reef Check Foundation is a 501(c)(3) nonprofit founded in 1996 and headquartered in Westlake Village, California, that operates the world's largest scuba-based citizen science monitoring program for tropical coral reefs and temperate kelp forests. The organization trains volunteer divers through its tiered EcoDiver certification program (EcoDiver, EcoDiver Trainer, EcoDiver Course Director) and standardized survey protocols covering fish belt transects, invertebrate transects, substrate line transects, and temperature monitoring, then aggregates the resulting data into a global database at data.reefcheck.org. Since conducting the first-ever global coral reef survey in 1997, Reef Check has accumulated over 17,000 surveys across 102 countries and territories, with 5,884 coral reef sites, 254 kelp forest monitoring sites along the West Coast of North America, and a Coastal Canary temperature logger network of 75+ California sites. The organization's offerings span core citizen-science programs (EcoDiver, Kelp Forest Monitoring, Dive into Science, Kelp Restoration, EcoExpeditions, Coastal Canary Project) and supporting products such as regional field guides, species ID cards, survey slates, transect tapes, and EcoDiver E-Kits priced $1–$149.99.

Reef Check's revenue model is dominated by contributed support — FY2024 total income of $1,647,795 was 96% contributed support ($1,581,617) and only 4% earned revenue ($66,178) — sourced from individual donations, corporate sponsors (SCE Edison, Houlihan Lokey, Dive N Surf, Google, Duckpin), major programmatic grants (SeaDoc Society ~$270,000 for 2026 projects), and multiple California state agencies including the Ocean Protection Council, State Coastal Conservancy, Coastal Commission, State Parks Outdoor Equity Program, and NOAA. Earned revenue comes from training courses ($199–$449 per participant), EcoExpedition fees (€1,460–€3,190) distributed through partners like Reef Check Italia/Coral Eye, Biosphere Expeditions, and Mora Mora Conservation/University of Marche, an annual membership program, an Adopt-a-Reef sponsorship program, and an e-commerce storefront. The organization is governed by a board led by Co-Chairs Helen Brierley and Robert McClatchy and operated by Executive Director Jan Freiwald, PhD, with 19 staff spanning program directors, regional managers across California, Oregon, Washington, and Baja California, and development/operations functions.

The customer base is hybrid: primary "customers" are recruited volunteer citizen-science scuba divers and under-resourced youth enrolled through the Dive into Science program, while downstream data and policy users include government marine resource managers, marine scientists, and ocean-enthusiast donors. Strategic positioning centers on a 25-year data moat, a global volunteer network across 40+ active chapters, and partnerships with universities (Moss Landing Marine Lab, Sonoma State), tribal nations (Tolowa Dee-ni', Coastal Chumash), and NGOs (The Nature Conservancy, Oregon Kelp Alliance, Waterman's Alliance, COBI) that anchor its restoration and equity work.

Core offering

Reef Check Foundation trains and certifies volunteer scuba divers (EcoDivers) to conduct standardized scientific monitoring surveys of tropical coral reefs and temperate kelp forests using belt transect methodologies (fish, invertebrate, substrate) and temperature loggers. The organization operates the original global coral reef citizen science program across 102 countries and territories, the largest kelp forest monitoring program along the West Coast of North America, and complementary restoration, education, and EcoExpedition programs.

Product overview

Reef Check Foundation is a nonprofit organization that operates a portfolio of citizen science programs focused on monitoring and restoring tropical coral reefs and temperate kelp forests. Its core offerings include the EcoDiver Program for tropical coral reef monitoring (with regional variants for Indo-Pacific, Caribbean, and Hawaii), the Kelp Forest Monitoring Program for West Coast ecosystems, and the Dive into Science Program for youth education. Supporting these programs are educational products including field guides, species identification cards, training manuals, underwater datasheets, and survey equipment kits. The organization also conducts EcoExpeditions to international reef locations, operates a kelp restoration program across multiple California and Oregon sites, and maintains a global database of over 17,000 reef health surveys spanning more than 25 years of monitoring data.
