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.

CORAL GHOSTS

 

Filming of the full-length documentary film, Coral Ghosts, directed and produced by Andrew Nisker, continued through the year with major filming sessions in Jamaica and the Marshall Islands following through on last year’s filming in Indonesia, the Great Barrier Reef, and the Canadian Arctic.

The film, now undergoing final edits, will premiere in Toronto early next year, and be broadcast on the Canadian Broadcasting Corporation. This will be the first documentary film to show long term changes in coral reefs around the world since the first underwater photographs, the causes for their current catastrophic decline, and how to regenerate them for the future.

GCRA will be delighted to arrange showings of Coral Ghosts for public education and to support fund-raising efforts with our many partner environmental groups world-wide. The short promotional trailer, which covers only a small part of the content of the documentary film, is shown below:
