Area - comparative	about 5.5 times the size of the US	slightly less than 1.5 times the size of the US
Background	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.	Speculation over the existence of a "southern land" was not confirmed until the early 1820s when British and American commercial operators and British and Russian national expeditions began exploring the Antarctic Peninsula region and other areas south of the Antarctic Circle. Not until 1840 was it established that Antarctica was indeed a continent and not just a group of islands. Several exploration "firsts" were achieved in the early 20th century. Following World War II, there was an upsurge in scientific research on the continent. A number of countries have set up year-round research stations on Antarctica. Seven have made territorial claims, but not all countries recognize these claims. In order to form a legal framework for the activities of nations on the continent, an Antarctic Treaty was negotiated that neither denies nor gives recognition to existing territorial claims; signed in 1959, it entered into force in 1961.
Climate	northeast monsoon (December to April), southwest monsoon (June to October); tropical cyclones occur during May/June and October/November in the northern Indian Ocean and January/February in the southern Indian Ocean	severe low temperatures vary with latitude, elevation, and distance from the ocean; East Antarctica is colder than West Antarctica because of its higher elevation; Antarctic Peninsula has the most moderate climate; higher temperatures occur in January along the coast and average slightly below freezing
Coastline	66,526 km	17,968 km
Country name	-	conventional long form: none conventional short form: Antarctica
Disputes - international	some maritime disputes (see littoral states)	Antarctic Treaty freezes claims (see Antarctic Treaty Summary in Government type entry); Argentina, Australia, Chile, France, NZ, Norway, and UK claim land and maritime sectors (some overlapping) for a large portion of the continent; the US and many other states do not recognize these territorial claims and have made no claims themselves (the US and Russia reserve the right to do so); no claims have been made in the sector between 90 degrees west and 150 degrees west; several states with territorial claims in Antarctica have expressed their intention to submit data to the UN Commission on the Limits of the Continental Shelf to extend their continental shelf claims to adjoining undersea ridges
Economy - overview	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.	Fishing off the coast and tourism, both based abroad, account for the limited economic activity. Antarctic fisheries in 2000-01 (1 July-30 June) reported landing 112,934 metric tons. Unregulated fishing, particularly of Patagonian toothfish, is a serious problem. The Convention on the Conservation of Antarctic Marine Living Resources determines the recommended catch limits for marine species. A total of 13,571 tourists visited in the 2002-03 antarctic summer, up from the 11,588 visitors the previous year. Nearly all of them were passengers on commercial (nongovernmental) ships and several yachts that make trips during the summer. Most tourist trips last approximately two weeks.
Elevation extremes	lowest point: Java Trench -7,258 m highest point: sea level 0 m	lowest point: Bentley Subglacial Trench -2,555 m highest point: Vinson Massif 4,897 m note: the lowest known land point in Antarctica is hidden in the Bentley Subglacial Trench; at its surface is the deepest ice yet discovered and the world's lowest elevation not under seawater
Environment - current issues	endangered marine species include the dugong, seals, turtles, and whales; oil pollution in the Arabian Sea, Persian Gulf, and Red Sea	in 1998, NASA satellite data showed that the antarctic ozone hole was the largest on record, covering 27 million square kilometers; researchers in 1997 found that increased ultraviolet light passing through the hole damages the DNA of icefish, an antarctic fish lacking hemoglobin; ozone depletion earlier was shown to harm one-celled antarctic marine plants; in 2002, significant areas of ice shelves disintegrated in response to regional warming
Geographic coordinates	20 00 S, 80 00 E	90 00 S, 0 00 E
Geography - note	major chokepoints include Bab el Mandeb, Strait of Hormuz, Strait of Malacca, southern access to the Suez Canal, and the Lombok Strait	the coldest, windiest, highest (on average), and driest continent; during summer, more solar radiation reaches the surface at the South Pole than is received at the Equator in an equivalent period; mostly uninhabitable

Legal system	-	Antarctica is administered through meetings of the consultative member nations; decisions from these meetings are carried out by these member nations (with respect to their own nationals and operations) in accordance with their own national laws; US law, including certain criminal offenses by or against US nationals, such as murder, may apply extra-territorially; some US laws directly apply to Antarctica; for example, the Antarctic Conservation Act, 16 U.S.C. section 2401 et seq., provides civil and criminal penalties for the following activities, unless authorized by regulation of statute: the taking of native mammals or birds; the introduction of nonindigenous plants and animals; entry into specially protected areas; the discharge or disposal of pollutants; and the importation into the US of certain items from Antarctica; violation of the Antarctic Conservation Act carries penalties of up to $10,000 in fines and one year in prison; the National Science Foundation and Department of Justice share enforcement responsibilities; Public Law 95-541, the US Antarctic Conservation Act of 1978, as amended in 1996, requires expeditions from the US to Antarctica to notify, in advance, the Office of Oceans, Room 5805, Department of State, Washington, DC 20520, which reports such plans to other nations as required by the Antarctic Treaty; for more information, contact Permit Office, Office of Polar Programs, National Science Foundation, Arlington, Virginia 22230; telephone: (703) 292-8030, or visit their website at www.nsf.gov; more generally, access to the Antarctic Treaty area, that is to all areas between 60 and 90 degrees latitude South, is subject to a number of relevant legal instruments and authorization procedures adopted by the states party to the Antarctic Treaty.

Maritime claims	-	Australia, Chile, and Argentina claim Exclusive Economic Zone (EEZ) rights or similar over 200 nm extensions seaward from their continental claims, but like the claims themselves, these zones are not accepted by other countries; 20 of 27 Antarctic consultative nations have made no claims to Antarctic territory (although Russia and the US have reserved the right to do so) and do not recognize the claims of the other nations; also see the Disputes - international entry
