Pacific Ocean in the World
Pacific Ocean - Introduction 2024
top of pageBackground: The Pacific Ocean is the largest of the world's five ocean basins (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 International Hydrographic Organization decision in 2000 to delimit a fifth world ocean basin, the Southern Ocean, removed the portion of the Pacific Ocean south of 60 degrees south. For convenience and because of its immense size, the Pacific Ocean is often divided at the Equator and designated as the North Pacific Ocean and the South Pacific Ocean.
Pacific Ocean - Geography 2024
top of pageLocation: body of water between the Southern Ocean, Asia, Australia, and the Western Hemisphere
Geographic coordinates: 0 00 N, 160 00 W
Map reference: Map of the world oceans
Area
Total: 168.723 million km²
Note: includes Arafura Sea, Bali Sea, Banda Sea, Bering Sea, Bering Strait, Celebes Sea, Coral Sea, East China Sea, Flores Sea, Gulf of Alaska, Gulf of Thailand, Gulf of Tonkin, Java Sea, Philippine Sea, Sea of Japan, Sea of Okhotsk, Solomon Sea, South China Sea, Sulu Sea, Tasman Sea, and other tributary water bodies
Comparative: about 15 times the size of the US; covers about 28% of the global surface; almost equal to the total land area of the world
Land boundaries
Coastline: 135,663 km
Maritime claims
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
Terrain
Elevation
Highest point: sea level
Lowest point: Challenger Deep in the Mariana Trench -10,924 m
Note: the Pacific Ocean is the deepest ocean basin
Mean depth: -4,080 m; ocean zones: Composed of water and in a fluid state, the ocean is delimited differently than the solid continents. It is divided into three zones based on depth and light level. Sunlight entering the water may travel about 1,000 m into the oceans under the right conditions, but there is rarely any significant light beyond 200 m.; The upper 200 m (656 ft) of the ocean is called the euphotic, or 'sunlight,' zone. This zone contains the vast majority of commercial fisheries and is home to many protected marine mammals and sea turtles. Only a small amount of light penetrates beyond this depth.; The zone between 200 m (656 ft) and 1,000 m (3,280 ft) is usually referred to as the 'twilight' zone, but is officially the dysphotic zone. In this zone, the intensity of light rapidly dissipates as depth increases. Such a minuscule amount of light penetrates beyond a depth of 200 m that photosynthesis is no longer possible.; The aphotic, or 'midnight,' zone exists in depths below 1,000 m (3,280 ft). Sunlight does not penetrate to these depths, and the zone is bathed in darkness.

Natural hazards: surrounded by a zone of violent volcanic and earthquake activity sometimes referred to as the 'Pacific Ring of Fire'; up to 90% of the world's earthquakes and some 75% of the world's volcanoes occur within the Ring of Fire; 80% of tsunamis, caused by volcanic or seismic events, occur within the 'Pacific Ring of Fire'; subject to tropical cyclones (typhoons) in southeast and east Asia from May to December (most frequent from July to October); tropical cyclones (hurricanes) may form south of Mexico and strike Central America and Mexico from June to October (most common in August and September); cyclical El Niño/La Niña phenomenon occurs in the equatorial Pacific, influencing weather in the Western Hemisphere and the western Pacific; ships subject to superstructure icing in extreme north from October to May; persistent fog in the northern Pacific can be a maritime hazard from June to December
Geography
Note: the major chokepoints are the Bering Strait, Panama Canal, Luzon Strait, and the Singapore Strait; the Equator divides the Pacific Ocean into the North Pacific Ocean and the South Pacific Ocean; dotted with low coral islands and rugged volcanic islands in the southwestern Pacific Ocean; much of the Pacific Ocean's rim lies along the Ring of Fire, a belt of active volcanoes and earthquake epicenters that accounts for up to 90% of the world's earthquakes and some 75% of the world's volcanoes; the Pacific Ocean is the deepest ocean basin averaging 4,000 m in depth

Etymology: named by Portuguese explorer Ferdinand MAGELLAN during the Spanish circumnavigation of the world in 1521; encountering favorable winds upon reaching the ocean, he called it 'Mar Pacifico,' which means 'peaceful sea' in both Portuguese and Spanish
