Following on from our research in the Society Islands, we continued with reef assessments round the Tuamotu islands. They constitute the largest archipelago in French Polynesia, spanning an area that is similar in size to Western Europe (but with a land area of only about 850 km2), and include 77 of the world’s 425 atolls. We focused on coral assessments of Rangiroa, Aratika, Raraka and Fakarava.

Global Reef Expedition Data Contributes to Landmark Report on the World’s Coral Reefs
More than a decade after scientists aboard the Global Reef Expedition surveyed coral reefs across the Pacific, the data they collected continues to contribute to our understanding of the world’s coral reefs.
Today, the Global Coral Reef Monitoring Network (GCRMN) released Status of Coral Reefs of the World: 2025, the most comprehensive assessment to date of the status and trends of coral reefs worldwide. The report brings together an extraordinary amount of information collected over more than four decades—and the Khaled bin Sultan Living Oceans Foundation is proud to have contributed data from the Global Reef Expedition to this global effort.
