About GCRA

The Global Coral Reef Alliance is a small, 501(c)(3) non-profit organization dedicated to growing, protecting and managing the most threatened of all marine ecosystems—coral reefs. Founded in 1990.

GCRA is a coalition of volunteer scientists, divers, environmentalists and other individuals and organizations, committed to coral reef preservation. We primarily focus on coral reef restoration, marine diseases and other issues caused by global climate change, environmental stress and pollution.

We employ a method which allows reefs to survive and recover from damage caused by excessive nutrients, climate change, and physical destruction. The mineral accretion, or the Biorock® Process, is owned by Biorock®, Inc. and is licensed to GCRA. This technology has been successfully applied to fish and shellfish mariculture as well as to growing limestone breakwaters to protect islands and coastal areas from erosion and rising sea levels. Coral reefs built with the Biorock process are now growing in Maldives, Seychelles, Thailand, Indonesia, Papua New Guinea, Mexico, Panama and, in one of the most remote and unexplored reef areas of the world, Saya de Malha Banks in the Indian Ocean.

GCRA scientists work with foundations, governments or private firms to build, restore and maintain coral reefs, nurseries and marine sanctuaries. Projects include restoration and construction of coral reefs for mariculture and tourism as well as breakwaters for shore protection.
