This inland sea of some 251,000 square kilometers is an extension of the Indian Ocean through the Strait of Hormuz. Its length is 989 kilometers, with Iran covering most of the northern coast and Saudi Arabia most of the southern coast. The Persian Gulf is about 56 km wide at its narrowest, in the Strait of Hormuz. The waters are overall very shallow, with a maximum depth of 90 metres and an average depth of 50 meters
The Persian Gulf has many fishing grounds, extensive coral reefs, and abundant pearl oysters, but its ecology has been damaged by radioactive debris from Earth’s World War III, and Pre Astroindustrialization and oil spills. It is just now (5050 OTT) really recovering from this human caused damage.
