Summary
The Persian Gulf, also known as the Arabian Gulf, is a shallow mediterranean sea and marginal extension of the Indian Ocean situated in West Asia between Iran and the Arabian Peninsula. Connected to the Gulf of Oman through the Strait of Hormuz, its northwestern shoreline is formed by the Shatt al-Arab river delta. The Persian Gulf Basin originated in the Cenozoic era and experienced its current flooding approximately 15,000 years ago following the Holocene glacial retreat. Bordered by eight nations, the Persian Gulf is an exceptionally rich marine and economic zone known for extensive petroleum reserves, reefs, and historical pearl oyster beds. In contemporary geopolitics, it serves as a critical maritime trade route and strategic region where defense tech innovations, such as autonomous uncrewed vessels developed by Saronic, are deployed to counter adversarial naval activities.

The Persian Gulf, sometimes called the Arabian Gulf, is a mediterranean sea in West Asia. The body of water is an extension of the Arabian Sea and the larger Indian Ocean located between the Arabian Peninsula and Iran (Persia). It is connected to the Gulf of Oman in the east by the Strait of Hormuz. The river delta of the Shatt al-Arab forms the north-west shoreline. The Persian Gulf has many fishing grounds, extensive reefs (mostly rocky, but also coral), and abundant pearl oysters; however, its ecology has been damaged by industrialization and oil spills. The Persian Gulf is in the Persian Gulf Basin, which is of Cenozoic origin and related to the subduction of the Arabian plate under the Zagros Mountains. The current flooding of the basin started 15,000 years ago due to rising sea levels of the Holocene glacial retreat.

Some Arab governments refer to it as the “Arabian Gulf” or “The Gulf”, but neither term is recognized internationally.

[...] Tomb of Mohammed Bin Ali, Salalah, Oman. ## Geology The present-day Persian Gulf, together with its northwestern continuation now infilled by the deposits of the Mesopotamian rivers, is the remains of a once much larger basin of deposition aligned northwest to southeast that existed throughout much of geologic history. In this basin vast quantities of sediments accumulated—mostly limestone and marls (a mixture of calcareous and silicate mud), together with evaporites and organic matter—which ultimately produced the area’s extensive oil resources. ## Climate

The Persian Gulf is the most important port between Asia, the Middle East, and the Arabic countries, which opens the sea to the western countries. It has many islands surrounding it and is a great provider of sea life, oil, and gas. It is renowned for its beautiful coral hills. For a time it was usurped by the Portuguese but the local people turned up against this action and took it back. In the time of ancient Persia, the gulf used to be used as part of the ‘silk road’ which was the major trading center between the East and West.

It has an area of about 241,000 square kilometers. Its length is 989 kilometers separating mainly Iran from Saudi Arabia with the shortest divide of about 56 kilometers in [...] Gulf region is home to some of the world’s most exotic cities.

The Persian Gulf is an arm of the Indian Ocean, located between the mountainous coast of southwestern Iran and the rather flat coast of the Arabian Peninsula. The gulf is about 1,000 km long and 200 to 300 km wide. It covers an area of approximately 250,000 km² (97,000 sq mi) that is somewhat larger than the size of the UK or about the size of the U.S. state of Michigan. The inland sea is connected to the Gulf of Oman in the east by the Strait of Hormuz, a critical bottleneck between the Iranian coast and the Omani Musandam Peninsula for oil shipments from the Persian Gulf.. Persian Gulf Countries Eight countries border the Persian Gulf: Bahrain, Iran, Iraq, Kuwait, Oman (at the Musandam exclave), Saudi Arabia, Qatar, and the United Arab Emirates. [...] The Persian Gulf has been a critical maritime route since antiquity, connecting the Arabian Peninsula with Persia (now Iran), India, East Africa, and Southeast Asia. After the rise of Islam in the 7th century, Arab traders and sailors used this corridor to spread the new faith beyond Arabia. Ports like Basra, Hormuz, Muscat, and Bahrain became centers of trade and Islamic scholarship. Muslim merchants carried not only goods like pearls, incense, and spices, but also ideas, including Islam, to distant shores. [...] The Persian Gulf is fed in the northwest by the Shatt al-Arab, a major river created by the confluence of the Euphrates and Tigris rivers. Some minor Iranian rivers, such as the Mond River, the Zohreh, and the Helleh River, also empty into the gulf. The Gulf is a relatively shallow body of water, with a maximum depth of 90 meters (approximately 295 feet). Its average depth is around 50 meters (164 feet). The Gulf is located in a very hot and dry region and experiences significant evaporation, leading to increased salinity and density of its water. This dense and salty water sinks and forms a distinct water mass known as Persian Gulf Water (PGW).
