Bay of Bengal a northern extended arm of the indian ocean, is located between latitudes 5Â°N and 22Â°N and longitudes 80Â°E and 100Â°E. It is bounded in the west by the east coasts of Sri Lanka and India, on the north by the deltaic region of the Ganges-Brahmaputra-Meghna river system, and on the east by the Myanmar peninsula extended up to the Andaman-Nicobar ridges.
The southern boundary of the Bay is approximately along the line drawn from Dondra Head in the south of Sri Lanka to the north tip of Sumatra. The Bay occupies an area of about 2.2 million sq km and the average depth is 2,600m with a maximum depth of 5,258m. Bangladesh is situated at the head of the Bay of Bengal. Bottom topography characterised by a broad U-shaped basin with its south opening to the Indian Ocean.
