The Indian Ocean is the third largest of the world's oceanic divisions, covering 70,560,000 km2 (27,240,000 sq mi) (approximately 20% of the water on the Earth's surface).[1] It is bounded by Asia on the north, on the west by Africa, on the east by Australia, and on the south by the Southern Ocean or, depending on definition, by Antarctica.[2] It is named after India.[3] The Indian Ocean is known as Ratnākara (Sanskrit: रत्नाकर), "the mine of gems" in ancient Sanskrit literature, and as Hind Mahāsāgar (Hindi: हिन्द महासागर), in Hindi.
