Overview:The endless expanses of the Indian Ocean are home to the last natural paradises: Remote atolls surrounded by coral reefs in crystal clear water. Whole regions of this ocean are still unexplored, many reefs are not marked on any map. The departure of the research vessel Agulhas II from the island of La Réunion marks the beginning of one of the greatest scientific adventures of our time. The expedition, initiated by Monaco Explorations with the support of the Prince Albert II of Monaco Foundation, lasted six weeks and led into the Western Indian Ocean along the Mascarene Plateau.
