Abstract :
This article presents recent studies made utilising the autonomous underwater vehicle (AUV) r2D4 of the Great Dodo Lava Plain at the Central Indian Mid-Ocean ridge system. r2D4 is a cruising type AUV weighing 1,600 kgf with a length of 4.4 m. It is fitted with a side scanning sonar, an interferometry sonar, a CTDO, and an in-situ chemical analyzer "GAMOS" for measurement of manganese concentration. This study benefits from the AUV\´s high performance in autonomy and reliability in hostile environments.
