Chagos Survey

Indian Ocean Expedition: Survey 1

The Chagos Archipelago is comprised of seven major atolls enclosing more than 60 islands, located approximately 300 nautical miles south of the Maldives. It has the largest living coral atoll on the planet.

The Marine Protected Area is the world’s biggest ‘no-take’ marine reserve and has the cleanest sea water ever tested. More than 200 different species of coral have been identified, and it is home to 50 species of sharks, skates and rays, 800 species of fish, and 2 species of endangered turtle.

We are aiming to sample a variety of sites within the British Indian Ocean Territory of Chagos, gathering images from at least 28 shallow reef transects. This represents data and imagery from approximately 50 linear kilometres of reef and approximately 20,000 images.
