The Arabian Sea is one of the largest seas
of the world. It is economically very important due to the presence of huge oil
fields of Arabia. The sea is known for its generally dry weather along the
Western coast and its long, deep sea routes free of islands and undersea ridges.
During the Roman period, the sea was known as the Erythraean Sea to the
European people. The ancient Vedic Indians called it “Sindhu Sagar”. The Arabs
call it “Bahr al-Arab”. Learn some interesting and useful Arabian Sea facts.

- Arabian Sea is strangely shaped like a man facing
westwards with his two hands extended outwardly. The forearm of the right hand
is the Persian Gulf and the upper arm is the Gulf of Oman. The right elbow is
the Strait of Hormuz. In the same way, the left forearm, upper arm and elbow
are the Red Sea, Gulf of Eden and the Strait of Bab el Mandeb, respectively.
- There are two more important gulfs on the
North Eastern shore of the sea. These are Gulf of Khambhat and Gulf of Kutch of
India.
- The sea is bounded by three large peninsulas
which are the Indian Peninsula, Arabian Peninsula and the Horn of Africa.
- The sea has borders with Asian countries –
India, Pakistan, Iran, Oman, United Arab Emirates, and Yemen. The two African
nations with such criteria are Djibouti and Somalia.
- Despite the Indian Subcontinent, most other
regions bordering the sea lack major rivers. The largest river which joins with
the sea is Indus. Other such important rivers are Narmada, Sabarmati, and Tapi
etc.
- The Arabian Sea does not have many large
islands. The major islands dotted over the sea are Socotra, Astola, Masirah, and
Lakshadweep Islands etc.
- The sea is very deep in most of its extent.
The average depth is 9800 ft (2900 mt).
- Wheatley Deep (19038 ft or 5803 m) is the
deepest point of the Arabian Sea.
- The climate over and around the sea is
controlled by the monsoon winds. The seasonal wind flows from the South Western
region to the Indian Peninsula from the month of Jun to August. From September
to November the wind returns back to its place of origin, so the direction of
the wind flow just reverses.
- The eastern part of the Arabian Sea
experiences decent rainfalls due to the rainy seasons but the Western and
Northern shore known for very little precipitations.
- Due to the lack of rainfalls and scarcity
of major rivers along with its general hot weather, the water of the sea has
high salinity.
