Area - comparative	about 15 times the size of the US; covers about 28% of the global surface; larger than the total land area of the world	slightly less than 1.5 times the size of the US
Background	The Pacific Ocean is the largest of the world's five oceans (followed by the Atlantic Ocean, Indian Ocean, Southern Ocean, and Arctic Ocean). Strategically important access waterways include the La Perouse, Tsugaru, Tsushima, Taiwan, Singapore, and Torres Straits. 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 Pacific 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	planetary air pressure systems and resultant wind patterns exhibit remarkable uniformity in the south and east; trade winds and westerly winds are well-developed patterns, modified by seasonal fluctuations; tropical cyclones (hurricanes) may form south of Mexico from June to October and affect Mexico and Central America; continental influences cause climatic uniformity to be much less pronounced in the eastern and western regions at the same latitude in the North Pacific Ocean; the western Pacific is monsoonal - a rainy season occurs during the summer months, when moisture-laden winds blow from the ocean over the land, and a dry season during the winter months, when dry winds blow from the Asian landmass back to the ocean; tropical cyclones (typhoons) may strike southeast and east Asia from May to December	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	135,663 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
Economy - overview	The Pacific Ocean is a major contributor to the world economy and particularly to those nations its waters directly touch. It provides low-cost sea transportation between East and West, extensive fishing grounds, offshore oil and gas fields, minerals, and sand and gravel for the construction industry. In 1996, over 60% of the world's fish catch came from the Pacific Ocean. Exploitation of offshore oil and gas reserves is playing an ever-increasing role in the energy supplies of the US, Australia, NZ, China, and Peru. The high cost of recovering offshore oil and gas, combined with the wide swings in world prices for oil since 1985, has led to fluctuations in new drillings.	Fishing off the coast and tourism, both based abroad, account for Antarctica's limited economic activity. Antarctic fisheries in 2004-05 (1 July-30 June) reported landing 147,000 metric tons (estimated fishing from the area covered by the Convention on the Conservation of Antarctic Marine Living Resources (CCAMLR), which extends slightly beyond the Antarctic Treaty area). Unregulated fishing, particularly of Patagonian toothfish, is a serious problem. The CCAMLR determines the recommended catch limits for marine species. A total of 26,245 tourists visited in the 2005-06 Antarctic summer, up from the 22,712 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: Challenger Deep in the Mariana Trench -10,924 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, sea lion, sea otter, seals, turtles, and whales; oil pollution in Philippine Sea and South China 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
