Bay of Bengal

Circulation in the Bay of Bengal is clockwise during the northwest monsoon, with a westward flow in the main ocean. This flow reverses during the southwest monsoon. The northern half of the bay is underlain by the Ganges Fan, a thick cone of sediment extending from the continental rise across the abyssal plain. This is the fastest-accumulating sediment in the world, originating high in the Himalayas, and supplied by the Brahmaputra River and the Ganges.
