The Global Coral Reef Alliance is a small, 501(c)(3) non-profit organization dedicated to scientific research and sustainable management of the most valuable and threatened of all ecosystems—coral reefs.

GCRA is a worldwide coalition of volunteer scientists, divers, environmentalists and other individuals and organizations, committed to coral reef preservation. We primarily focus on coral reef restoration, and cutting-edge research on impacts of coral bleaching, global warming, marine diseases, global sea level rise, and pollution on corals.

GCRA scientists work with community groups, environmental organizations, foundations, governments or private firms to build, restore and maintain coral reefs, nurseries and marine sanctuaries. 

GCRA Projects include restoration of coral reefs and marine habitats for mariculture, tourism and shore protection.

GCRA invented and developed Mineral Accretion Technology™ and the Biorock™ method of electrical coral reef and marine ecosystem restoration, the HotSpot™ method to correctly predict coral bleaching from satellite sea surface temperatures, and integrated whole-watershed and coastal zone nutrient management (now commonly referred to as Ridge to Reef, or Hilltop to Ocean).

Founded in 1990, GCRA is the direct heir to a pioneering coral reef research tradition stretching back to the 1920s, and has the world’s largest collection of coral reef photographs from the 1940s, 1950s, and 1960s.
