Chagos Marine Protected Area, Marine reserve in central Indian Ocean.
The Chagos Marine Protected Area is a large ocean conservation zone in the central Indian Ocean, made up of seven atolls and around 70 islands. The waters cover coral reefs built on limestone structures as well as deep-sea habitats that extend far below the surface.
The zone was designated as a marine reserve in 2010, following years of debate about protecting the ecosystems of this remote part of the ocean. It is managed under British jurisdiction as part of the British Indian Ocean Territory.
The area takes its name from the Chagos Archipelago, a group of islands at the center of the Indian Ocean. The reefs here are among the least affected by human activity anywhere on Earth, which gives them a clarity and life rarely seen elsewhere.
Entry to this protected zone requires advance permission from the relevant authorities, and requests should be made well ahead of any planned visit. The area is very remote, so anyone heading there should be fully prepared for long ocean travel with limited support nearby.
The seafloor beneath these waters holds numerous underwater mountains and knolls, many of which have never been fully mapped. Researchers visit specifically to study these formations, which offer a rare chance to observe deep-sea life in a setting almost untouched by human presence.
