Country Profile: Indian Ocean
The Indian Ocean, the third-largest ocean basin in the world, is situated between Africa, the Southern Ocean, Asia, and Australia. Spanning an area of approximately 70.56 million square kilometers, it is characterized by critical chokepoints such as the Suez Canal and the Strait of Hormuz. The region supports diverse ecosystems and significant economic activities, including fisheries that contribute notably to global seafood supplies. While the Indian Ocean's governance is linked to various nations surrounding it, environmental concerns, particularly marine pollution and biodiversity loss, pose significant challenges.
Geography
The Indian Ocean is the third-largest ocean, defined geographically by the boundaries of Africa to the west, Asia to the north, and Australia to the east. It covers a total area of 70.56 million square kilometers, nearly seven times the size of the United States, and features a coastline of 66,526 kilometers. The ocean has a mean depth of 3,741 meters, with the Java Trench being its deepest point at 7,192 meters.
- 264 million cubic kilometers: Total ocean volume, comprising 19.8% of the world's ocean volume.
- Major currents: The Indian Ocean Gyre consists of warm and cold currents that influence regional climates.
- Natural resources: Includes oil and gas fields, abundant fish stocks, and polymetallic nodules.
Environment
The Indian Ocean faces significant environmental challenges, including marine pollution from oil spills and improper waste disposal. It is home to diverse marine species, but many are endangered due to habitat loss and fishing pressures. The ocean's fisheries are crucial, accounting for 15.5% of the global catch in 2020, yet the region's coral reefs and biodiversity are under threat.
- 12.22 million metric tons: Global catch from Indian Ocean fisheries in 2020.
- 8.4%: Contribution of the Eastern Indian Ocean to the global catch, significant for species like tuna and shrimp.
- Endangered species: Various marine species are threatened, highlighting conservation needs.
