Bay of Bengal geographical map

A bay belonging to the Indian Ocean. It is embedded in Sri Lanka (Ceylon) to the west, India to the north, Myanmar and the Andaman-Nicobar Ridge to the east, and the line connecting Cape Dondela at the southern end of Sri Lanka and Cape Urellue at the northwest end of Sumatra to the south. boundary. The southern border is approximately 1,609 kilometers long. The part of the Andaman-Nicobar Ridge that emerges from the sea, with the Andaman Islands in the north and the Nicobar Islands in the south, separates the Bay of Bengal from the Andaman Sea in the east. At the top of the bay are the giant deltas of the Ganges and Brahmaputra rivers. Other rivers flowing into the bay are the Mahanadi, Godavari and Krishna rivers in India. The Bay of Bengal (named after the Indian state of Mongolia) has a total area of 2.172 million square kilometers, a total volume of 5.616 million cubic kilometers, and an average water depth of 2,586 meters.

Geographical map of the Bay of Bengal

The continental shelf of the Bay of Bengal is 161 kilometers wide, wider in the north and east. The average depth of the continental shelf on the seaward side is 183 meters. Most of the continental shelf is composed of sand, and the seaward side is mostly clay and soft mud. It is cut by submarine canyons in several places. Among them are the Ganges Canyon, located outside the Ganges-Brahmaputra Delta, with a depth of 732 meters; Andhra, Krishna and Mahadevan Canyons are located on the western edge of the bay.

The deep-sea disk of the Bay of Bengal is roughly U-shaped, with a depth of 4,500 meters. The basin floor has two features: in the north there is a very straight, 5000 km long east longitude 90. and the Ganges delta, formed by alluvial sediments from the continental shelf. Longitude 90. At the top of the ridge, the water depth is about 2134 meters, and its northern end is covered with sediments from the Ganges Delta. The delta is dotted with dendritic gullies (fan valleys). This allows sediments to be transported to distant deep ocean basins.

The surface circulation in the Bay of Bengal is strongly affected by the monsoon. In spring and summer, moist southwesterly winds cause clockwise circulation. In autumn and winter, due to the influence of northeasterly winds, they change into counterclockwise circulation. Due to the topographic effect of the Bay of Bengal, various forces are focused. Therefore, phenomena such as tidal range, static vibration and internal waves are all significant.
