The Bay of Bengal is a bay that forms the northeastern part of the Indian Ocean. It resembles a triangle in shape, and is bordered on the east by Malay Peninsula, and on the west by India. On the northern tip of the "bay" lies the Bengal region, comprising the Indian state of West Bengal and the country of Bangladesh, thus the name. The southern extremes reach the island country of Sri Lanka, and the Indian Union Territory of Andaman and Nicobar Islands.

The Bay of Bengal occupies an area of 2,172,000 sq kms. It is bordered by India and Sri Lanka to the West, Bangladesh to the North, and Myanmar and the southern part of Thailand to the East. Its southern boundary extends as an imaginary line from Dondra Head at the southern end of Sri Lanka to the northern tip of Sumatra. A number of large rivers – Ganges, Brahmaputra, Irrawaddy, Godavari, Mahanadi, Krishna and Cauvery – flow into the Bay of Bengal. Among the important ports are Yangon, Kolkata/Calcutta, Cuddalore, Kakinada, Machlipatnam, Madras, Paradip and Vishakapatnam.

[edit] Etymlogy

In the 10th century conflicts caused the Bay of Bengal to be called "The Chola Lake". Bangal ki Khadi is the name in Hindi. ^[1]

Bengal comes from the Sanskrit Banga or Vanga and refers to the Gangetic delta waters. There is mythology which relates the area given to the Lunar race of Delhi.^[2]^[3]

[edit] Rivers

Many major rivers of India flow west to east into the Bay of Bengal: in the north, the Ganges River (or Ganga), Meghna River and Brahmaputra River rivers, and in the south Mahanadi River through the Mahanadi River Delta, Godavari River, Krishna River, Irrawaddy and Kaveri River (sometimes written as Cauvery) rivers. The Sundarbans mangrove forest is formed at the delta of the Ganga, Brahmaputra and Meghna rivers on the Bay of Bengal. The Ayeyarwady River of Myanmar also flows into the bay.

[edit] Seaports

Major Bangladeshi ports on the bay include Chittagong and Mongla. Major Indian ports on the bay include Chennai (formerly Madras), Vishakhapatnam, Kolkata (formerly Calcutta), and Pondicherry. Yangon, the largest city and former capital of Myanmar is also an important port in the bay.

[edit] Islands

St.Martin Island, Bay of Bengal

The islands in the bay are very numerous, including the Andaman, Nicobar and Mergui groups. The group of islands, Cheduba and others, in the north-east, off the Burmese coast, are remarkable for a chain of mud volcanoes, which are occasionally active. Great Andaman is the main archipelago or island group of the Andaman Islands, whereas Ritchie's Archipelago consists of smaller islands.

[edit] Oceanography

Oceanography is the study of oceans and the ocean floor by scientific exploration and scientific methods. The Bay of Bengal is a salt water sea and is a part of the Indian Ocean.

Volcanic Arc System: Nicobar Islands & Andaman Islands

The lithosphere of the earth is broken up into what are called tectonic plates. Underneath the Bay of Bengal is the The India Plate which is part of the great Indo-Australian Plate and is slowly moving north east. This plate meets the Burma Microplate at the Sunda Trench. The Nicobar Islands, and the Andaman Islands are part of the Burma Microplate. The India Plate subducts beneath the Burma Plate at the Sunda Trench or Java Trench. Here, the pressure of the two plates on each other increase pressure and temperature resulting in the formation of volcanoes such as the volcanoes in Myanmar, and a volcanic arc called the Sunda Arc. Sumatra-Andaman earthquake and Asian Tsunami was a result of the pressure at this zone causing a submarine earthquake which then resulted in a huge Tsunamai. ^[4]

[edit] Marine geology

A zone 50m wide extending from the island of Ceylon and the Coromandel coast to the head of the bay, and thence southwards through a strip embracing the Andaman and Nicobar islands, is bounded by the ioo fathom line of sea bottom; some 50 m. beyond this lies the Soo-fathom limit. Opposite the mouth of the Ganges, however, the intervals between these depths are very much extended by deltaic influence.

Swatch of No Ground is a 14km-wide deep sea canyon of the Bay of Bengal. The deepest recorded area of this valley is about 1340m.^[5]

[edit] Marine biology, flora and fauna

The Bay of Bengal is full of biological diversity, diverging amongst coral reefs, estuaries, fish spawning and nursery areas, and mangroves. The Bay of Bengal is one of the World's 64 largest marine ecosystems.

Kerilia jerdonii is a sea snake of the Bay of Bengal. Glory of Bengal Cone (Conus bengalensis) is just one of the seashells which can be photographed along beaches of the Bay of Bengal.^[6]

An endagnered species, the Olive Ridley sea turtle can survive because of the nesting grounds made available at the Gahirmatha Marine Wildlife Sanctuary, Gahirmatha Beach, Orissa, India.

Marlin, barracuda, skipjack tuna, (Katsuwonus pelamis), yellowfin tuna, Indo-Pacific humpbacked dolphin (Sousa chinensis) , and Bryde's whale (Balaenoptera edeni) are a few of the marine animals. Bay of Bengal Hogfish (Bodianus neilli) is a type of Wrass which live in turbid lagoon reefs or shallow coastal reefs. Schools of dolphins can be seen, whether they are the bottle nose dolphin (Tursiops truncatus), Pantropical spotted dolphin (Stenella attenuata) or the spinner dolphin (stenella longirostris) . Tuna and dolphins are usually residing in the same waters. In shallower and warmer coastal waters the Irrawaddy Dolphins (Orcaella brevirostris) can be found. ^[7]^[8]

The Great Nicobar Biosphere Reserve proides sanctuary to many animals some of which include the saltwater crocodile (Crocodylus porosus) , giant Leatherback Sea Turtle (Dermochelys coriacea) , and Malayan box turtle (Cuora amboinensis kamaroma) to name a few.

[edit] Physical oceanography - Climate of the Bay of Bengal

From January to October, the current is northward flowing, and the clockwise circulation pattern is called the "East Indian Current." The Bay of Bengal monsoon moves in a northwest direction striking the Nicobar Islands, and the Andaman Islands first end of May, then the North Eastern Coast of India by end of June.

The remainder of the year, the conterclockwise current is southwestward flowing, and the circulation pattern is called the East Indian Winter Jet. September and December see very active weather, season varsha (or monsoon), in the Bay of Bengal producing severe Cyclones which affect Eastern India. Several efforts have been initiated to cope with Storm surge.^[11]

[edit] Marine Archeology

Maritime archaeology or marine archaeology is the study of material remains of ancient peoples. A specialized branch, Archaeology of shipwrecks studies the salvaged artifacts of ancient ships. Stone anchors, amphorae sherds, elephant tusks, hippopotamus teeth, ceramic pottery , a rare wood mast and lead ingots are examples which may survive the test of time for archaeologists to study and place the salvaged findings into a time line of history. Coral reefs, tsuanamis, cyclones, mangrove swamps, battles and a criss cross of sea routes in a high trading area combined with pirating have all contributed to shipwrecks in the Bay of Bengal. ^[22]
