The area is near the Strait of Hormuz, a strategic route through which a third of the world's liquefied natural gas and 20% of global oil consumption passes from Middle East producers.[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 (63,700 sq mi) Gulf of Oman, 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.[11]
