Pacific Ocean in the World

Pacific Ocean - Introduction 2025

top of page

Background: 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.

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
Mean depth: -4,080 m
Ocean zones: the ocean 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 below 200 m
Euphotic zone: the upper 200 m (656 ft) is also called 'sunlight' zone; only a small amount of light penetrates beyond this depth
Dysphotic zone: between 200 m (656 ft) and 1,000 m (3,280 ft), and also called the twilight zone; the intensity of light rapidly dissipates as depth increases, and photosynthesis is no longer possible
Aphotic zone: below 1,000 m (3,280 ft) and also called the midnight zone; sunlight does not penetrate to these depths
Note: the Pacific Ocean is the deepest ocean basin

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, which is a belt that contains about 75% of the world's volcanoes and up to 90% of the world's earthquakes; the Pacific Ocean is the deepest ocean basin, averaging 4,000 m (13,123 ft) in depth
