Safety Measures 

Swimmers must follow the instructions of lifeguards and obey posted information about water conditions, tides and other dangers.

For inexperienced recreational swimmers, many safety hazards exist-even in a pool. These hazards include misjudging a dive and hitting one's head on the bottom, holding one's breath too long and experiencing sudden cramps. 

In rivers and oceans, all swimmers should respect the power of nature. Powerful waves, tides, and currents can easily overpower even the most experienced swimmers, sweeping them out beyond safety or throwing them into coral or rocks.

Indian Ocean

Indian Ocean is the third largest of earth's four oceans, (after the Pacific Ocean and Atlantic Ocean, but larger than the Arctic Ocean) which extends from South Asia to Antarctica and from East Africa to South East Australia.

Area: Total area of the Indian Ocean is 73,427,000 sq km (28,350,000 sq mi). It includes the Arabian Sea, Bay of Bengal, Andaman Sea, Red Sea,Gulf of Oman, Strait of Malacca, Great Australian Bight, Mozambique Channel, and other tributary water bodies which constitutes about 20% of the world's total ocean area. 

Depth: The average depth of the Indian Ocean is 3,900 m (12,800 ft), or slightly greater than that of the Atlantic, and the deepest known point is 7,725 m (25,344 ft), off the southern coast of the Indonesian island of Java. 

Islands:The Indian Ocean contains numerous islands, the largest of which are Madagascar and Sri Lanka. Smaller islands include the Andaman and Nicobar Islands; the Seychelles and the Kerguelen Islands are exposed tops of submerged ridges. The Lakshadweep (Laccadives), the Maldives, and the Chagos are low coral islands, and Mauritius and Réunion are high volcanic cones.

Rivers: The Indian Ocean receives the waters of the Zambezi, Tigris-Euphrates, Indus, Ganges-Brahmaputra, and Irrawady rivers. The surface waters of the ocean are generally warm, although close to Antarctica pack ice and icebergs are found. The southwest monsoon draws moisture from the Indian Ocean and drops heavy rainfall on the Indian subcontinent and Southeast Asia.

Economy: 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 oil fields 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, Korea, and Taiwan also exploit the Indian Ocean, mainly for shrimp and tuna. An estimated 40% of the world's offshore oil production comes from the Indian Ocean.
