The Gulf of Oman historically and geographically has been referred to by different names by Arabian, Iranian, Indian, Pakistani, and European geographers and travelers, including Makran Sea and Akhzar Sea.[8][9]
Makran Sea
Akhzar Sea
Persian Sea (consists of the whole of the Persian Gulf and Gulf of Oman)
Until the 18th century, it was known as Makran Sea and is also visible on historical maps and museums.[10]
In 2018, scientists confirmed the Gulf of Oman contains one of the world's largest marine dead zones, where the ocean contains little or no oxygen and marine wildlife cannot exist. The dead zone encompasses nearly the entire 165,000-square-kilometre (63,700sqmi) Gulf of Oman and equivalent to the size of Florida, United States of America. The cause is a combination of increased ocean warming and increased runoff of nitrogen and phosphorus from fertilizers.[12]
International underwater rail tunnel
In 2018, a rail tunnel under the sea was suggested to link the UAE with the western coast of India. The bullet train tunnel would be supported by pontoons and be nearly 2,000 kilometres (1,200mi) in length.[13][14]
