Background | The Iles Eparses, or scattered islands, are a group of five French entities - Bassas da India, Europa Island, Glorioso Islands, Juan de Nova Island, and Tromelin Island - which on 1 April 1960 came under the authority of the Minister in charge of overseas possessions. On 19 September 1960 by decree, the islands were transferred to the charge of the Prefet of Reunion where they remained until 3 January 2005 when they were transferred by another decree to the Senior Administrator of the Territory of the French Southern and Antarctic Lands (TAAF).
Bassas da India: A French possession since 1897, this atoll is a volcanic seamount surrounded by reefs and awash at high tide. Europa Island: A French possession since 1897, the island is heavily wooded; it is the site of a small military garrison that staffs a weather station. Glorioso Islands: A French possession since 1892, the Glorioso Islands are composed of two lushly vegetated coral islands (Ile Glorieuse and Ile du Lys) and three rock islets. A military garrison operates a weather and radio station on Ile Glorieuse. Juan de Nova Island: Named after a famous 15th century Spanish navigator and explorer, the island has been a French possession since 1897. It has been exploited for its guano and phosphate. Presently a small military garrison oversees a meteorological station. Tromelin Island: First explored by the French in 1776, the island came under the jurisdiction of Reunion in 1814. At present, it serves as a sea turtle sanctuary and is the site of an important meteorological station. |
The Indian Ocean is the third largest of the world's five oceans (after the Pacific Ocean and Atlantic Ocean, but larger than the Southern Ocean and Arctic Ocean). Four critically important access waterways are the Suez Canal (Egypt), Bab el Mandeb (Djibouti-Yemen), Strait of Hormuz (Iran-Oman), and Strait of Malacca (Indonesia-Malaysia). The decision by the International Hydrographic Organization in the spring of 2000 to delimit a fifth ocean, the Southern Ocean, removed the portion of the Indian Ocean south of 60 degrees south latitude. |

Economy - overview | no economic activity | The Indian Ocean provides major sea routes connecting the Middle East, Africa, and East Asia with Europe and the Americas. It carries a particularly heavy traffic of petroleum and petroleum products from the oilfields of the Persian Gulf and Indonesia. Its fish are of great and growing importance to the bordering countries for domestic consumption and export. Fishing fleets from Russia, Japan, South Korea, and Taiwan also exploit the Indian Ocean, mainly for shrimp and tuna. Large reserves of hydrocarbons are being tapped in the offshore areas of Saudi Arabia, Iran, India, and western Australia. An estimated 40% of the world's offshore oil production comes from the Indian Ocean. Beach sands rich in heavy minerals and offshore placer deposits are actively exploited by bordering countries, particularly India, South Africa, Indonesia, Sri Lanka, and Thailand. |

surface dominated by counterclockwise gyre (broad, circular system of currents) in the southern Indian Ocean; unique reversal of surface currents in the northern Indian Ocean; low atmospheric pressure over southwest Asia from hot, rising, summer air results in the southwest monsoon and southwest-to-northeast winds and currents, while high pressure over northern Asia from cold, falling, winter air results in the northeast monsoon and northeast-to-southwest winds and currents; ocean floor is dominated by the Mid-Indian Ocean Ridge and subdivided by the Southeast Indian Ocean Ridge, Southwest Indian Ocean Ridge, and Ninetyeast Ridge |
