Bassas da India is an uninhabited, roughly circular atoll that is part of the French Southern and Antarctic Lands. Located in the southern Mozambique Channel, about halfway between Mozambique and Madagascar (about 385 km (239 mi) further east) and around 110 km (68 mi) northwest of Europa Island, the rim of the atoll averages around 100 m in width and encloses a shallow lagoon of depth no greater than 15 m. Overall, the atoll is about 10 km (6 mi) in diameter, rising steeply from the seabed 3000 m below to encircle an area (including lagoon) of 80 km (31 sq mi). Its Exclusive Economic Zone (EEZ), 123,700 km (47,761 sq mi) in size, is contiguous with that of Europa Island.
