Country Profile: Indian Ocean

The Indian Ocean is the third-largest ocean basin, bordered by Africa, Asia, Australia, and the Southern Ocean. This vast body of water encompasses a total area of approximately 70.56 million square kilometers, making it almost seven times the size of the United States. It plays a crucial role in global trade, with significant shipping routes such as the Suez Canal and the Strait of Hormuz. The ocean's diverse ecosystem is home to rich marine resources, vital for the economies of the countries surrounding it and impacted by various environmental concerns.

Geography

The Indian Ocean is situated between Africa, the Southern Ocean, Asia, and Australia, featuring a vast area of 70.56 million square kilometers. It has a coastline of 66,526 kilometers and experiences a range of climate patterns influenced by monsoons. Known for its significant ocean currents and geological features, the Indian Ocean includes both shallow continental shelves and deep abyssal plains.

  • 4 major chokepoints: Bab el Mandeb, Strait of Hormuz, Strait of Malacca, and southern access to the Suez Canal.
  • 19.8% of the total volume of the world's oceans is found here, equating to 264 million cubic kilometers.
  • The ocean's mean depth is 3,741 meters, with the deepest point at the Java Trench, reaching -7,192 meters.

Environment

The Indian Ocean faces several environmental challenges, including marine pollution from waste and oil spills, particularly in the Arabian Sea and Persian Gulf. There are significant threats to coral reefs and biodiversity, with various marine species classified as endangered. Marine fisheries, while essential for local economies, also contribute to the ecological stress in the region.

  • 15.5% of the global marine catch in 2020 was sourced from the Indian Ocean, totaling 12,220,000 metric tons.
  • Major fisheries are categorized into the Eastern Indian Ocean and Western Indian Ocean, with 8.4% and 7.1% of global catches, respectively.
  • The Indian Ocean's fishing regions support key species such as tuna, small pelagic fish, and shrimp.
