Country Profile: Indian Ocean

The Indian Ocean is the third-largest ocean basin in the world, bordered by Africa, the Southern Ocean, Asia, and Australia. It covers an area of approximately 70.56 million square kilometers, making it nearly seven times the size of the United States. The region is vital for global trade, featuring critical access waterways such as the Suez Canal and the Strait of Hormuz. Its unique geography supports a diverse marine ecosystem, while its waters host essential fisheries. The Indian Ocean is also subject to various environmental challenges, including marine pollution and loss of biodiversity.

Geography

The Indian Ocean is situated between Africa, the Southern Ocean, Asia, and Australia, with geographic coordinates of 20°S and 80°E. It encompasses various significant water bodies, including the Arabian Sea and the Bay of Bengal, and boasts a coastline of 66,526 kilometers. The region's climate is characterized by monsoon seasons, with tropical cyclones occurring at specific times of the year. Its major ocean currents create a unique hydrological environment that impacts both marine life and global weather patterns.

264 million cu km: volume of the Indian Ocean, comprising 19.8% of the world ocean's total volume.
-7,192 m: deepest point at the Java Trench.
3,741 m: mean depth of the ocean.
70.56 million sq km: total area of the Indian Ocean.
Major chokepoints include Bab el Mandeb and the Strait of Hormuz.

Environment

The Indian Ocean faces several environmental challenges, including marine pollution due to dumping and oil spills, particularly in the Arabian Sea, Persian Gulf, and Red Sea. Coral reefs are threatened, and there is a significant loss of biodiversity, impacting numerous endangered marine species. Despite these issues, the ocean supports vital marine fisheries, accounting for approximately 15.5% of the global catch.

15.5%: share of global fish catch from the Indian Ocean in 2020, totaling 12.22 million metric tons.
Major fisheries production regions include the Eastern Indian Ocean (6.59 million metric tons) and the Western Indian Ocean (5.63 million metric tons).
Key marine species include tuna, small pelagic fish, and shrimp.
