Arabian Sea: Indian Ocean
built 617 days ago
The Arabian Sea forming much of India's Southwestern border is a lifeline of the coastal hamlets. It is ... an important route of water transportaion within India and serves as the base of the fishing industry on the west-coast. In Indian folklore, it is referred to as Daria, Sindhu Sagar, and Arabbi Samudra.

The Arabian Sea is a sea between Arabian Peninsula and the Indian peninsula. It covers around 4,600,000, km. The Arabian Sea one of the warmest seas. The Indus River empties into this sea.
The Arabian Sea has the saltiest surface water in the Indian Ocean. High salinity water flows out from the Red Sea along the bottom of the Strait of Bab el Mandeb. It sinks, mixes with the surrounding water, and spreads at great depths as far as Ceylon and southern Africa. Little fresh water dilutes the salty currents since few large rivers empty into the Arabian Sea—only the Indus, Narbadi, and Tapti rivers, all from India.
The Arabian Sea has two important branches — the Gulf of Aden in the southwest, connecting with the Red Sea through the strait of Bab-el-Mandeb; and the Gulf of Oman to the northwest, connecting with the Persian Gulf. Besides these larger ramifications, there are the gulfs of Cambay and Kutch on the Indian coast. Its islands are few, the chief being Socotra, off the African, and the Laccadives, off the Indian coast.
The Holocene record on the coasts of the Arabian Sea provides information on the nature and rate of deformation generated by the interaction between the Indian, Arabian and Eurasian Plates. Holocene marine terraces show that the southern Makran has been subject to the infrequent but vigorous coseismic uplift (2 m) that characterizes other subduction settings and they indicate landward rotation of the imbricate faults among which shortening is distributed. The lack of significant Holocene deformation on the SE coast of the Arabian peninsula is consistent with its position parallel to a transform, although there is evidence for large-scale buckling driven by convergence at the Strait of Hormuz in the NE. Geomorphological and tide-gauge evidence for localized uplift on the southwestern coast of India may represent compressional buckling here too in response to Himalayan collision. Bathymetric and geodetic data can help to bridge these sequences and ... enhance their value for quantifying plate rheology and dynamics, notably by linking variations in plate-margin displacement with major sea-floor strike-slip structures and by eventually confirming transitory as well as sustained compressive buckling on land.
The Arabian Sea is predominantly semi-diurnal in nature, becoming more so as the co-oscillating tides from the Indian Ocean proper propagate into the Arabian Sea. The vertically averaged velocity vectors are overlayed the sea surface height (SSH) deflection. The effect of the diurnal tides on the SSH is readily apparent as shown by the difference between the semi-diurnal low tides occurring at approximately the hours of 11 and 23.
