The Pacific Ocean is the largest of the Earth
's ocean
ic divisions. It extends from the Arctic
in the north to the Southern Ocean
(or, depending on definition, to Antarctica) in the south, bounded by Asia
and Australia
in the west, and the Americas
in the east.
At 165.2 million square kilometres (64.1 million square miles) in area, this largest division of the World Ocean
– and, in turn, the hydrosphere
– covers about 46% of the Earth's water surface and about one-third of its total surface area, making it larger than all of the Earth's land area combined. The equator
subdivides it into the North Pacific Ocean and South Pacific Ocean, with two exceptions: the Galápagos
and Gilbert Islands
, while straddling the equator, are deemed wholly within the South Pacific. The Mariana Trench
in the western North Pacific is the deepest point in the world, reaching a depth of 10911 metres (35,797.2 ft).
The Pacific Ocean was sighted by Europeans early in the 16th century, first by the Spanish explorer Vasco Núñez de Balboa
, who crossed the Isthmus of Panama
in 1513 and named it Mar del Sur (South Sea). Its current name was given by Portuguese
explorer Ferdinand Magellan
during the Spanish expedition of world circumnavigation
in 1521, who encountered favourable winds as he reached the ocean and called it Mar Pacifico in Portuguese
, meaning "peaceful sea".
The Pacific Ocean encompasses approximately one-third of the Earth
's surface, having an area of 165.2 million square kilometres (64.1 million square miles) —significantly larger than Earth's entire landmass, with room for another Africa
to spare.
Extending approximately 15,500 kilometres (9,600 mi) from the Bering Sea
in the Arctic
to the northern extent of the circumpolar Southern Ocean
at 60°S
(older definitions extend it to Antarctica's Ross Sea
), the Pacific reaches its greatest east-west width at about 5°N latitude
, where it stretches approximately 19,800 kilometres (12,300 mi) from Indonesia
to the coast of Colombia
and Peru
– halfway across the world, and more than five times the diameter of the Moon. The lowest known point on earth—the Mariana Trench
—lies 10,911 metres (35,797 ft) below sea level. Its average depth is 4028~4188metres (14,000 ft).
The Pacific Ocean is currently shrinking due to plate tectonics
, while the Atlantic Ocean
is increasing in size, by roughly an inch per year (2–3 cm/yr) on 3 sides, roughly averaging 0.2 square mile (0.517997622 km²) a year.
Along the Pacific Ocean's irregular western margins lie many seas, the largest of which are the Celebes Sea
, Coral Sea
, East China Sea
, Philippine Sea
, Sea of Japan
, South China Sea
, Sulu Sea
, Tasman Sea
, and Yellow Sea
. The Strait of Malacca
joins the Pacific and the Indian Ocean
s on the west, and Drake Passage
and the Straits of Magellan link the Pacific with the Atlantic Ocean
on the east. To the north, the Bering Strait
connects the Pacific with the Arctic Ocean
.
As the Pacific straddles the 180th meridian
, the West Pacific (or western Pacific, near Asia) is in the Eastern Hemisphere
, while the East Pacific (or eastern Pacific, near the Americas) is in the Western Hemisphere
.
For most of Magellan's voyage from the Strait of Magellan
to the Philippines
, the explorer indeed found the ocean peaceful. However, the Pacific is not always peaceful. Many tropical storms batter the islands of the Pacific. The lands around the Pacific Rim
are full of volcano
es and often affected by earthquake
s. Tsunami
s, caused by underwater earthquakes, have devastated many islands and in some cases destroyed entire towns.
The volume of the Pacific Ocean is approximately 622 million cubic km. Water temperatures in the Pacific vary from freezing in the poleward areas to about 30 °C (86 °F) near the equator. Salinity
also varies latitudinally. The water near the equator is less salty than that found in the mid-latitudes because of abundant equatorial precipitation throughout the year. Poleward of the temperate latitudes salinity is also low, because little evaporation of seawater takes place in these frigid areas.
The motion of Pacific waters is generally clockwise in the Northern Hemisphere
(the North Pacific gyre) and counter-clockwise in the Southern Hemisphere
. The North Equatorial Current
, driven westward along latitude 15°N
by the trade wind
s, turns north near the Philippines
to become the warm Japan or Kuroshio Current
.
Turning eastward at about 45°N, the Kuroshio forks and some waters move northward as the Aleutian Current
, while the rest turn southward to rejoin the North Equatorial Current. The Aleutian Current branches as it approaches North America and forms the base of a counter-clockwise circulation in the Bering Sea
. Its southern arm becomes the chilled slow, south-flowing California Current
.
The South Equatorial Current
, flowing west along the equator, swings southward east of New Guinea
, turns east at about 50°S
, and joins the main westerly circulation of the Southern Pacific, which includes the Earth-circling Antarctic Circumpolar Current
. As it approaches the Chile
an coast, the South Equatorial Current divides; one branch flows around Cape Horn
and the other turns north to form the Peru or Humboldt Current
.
The ocean was mapped by a man named Abraham Ortelius; he called it Maris Pacifici because of Ferdinand Magellan
, who sailed the Pacific during his circumnavigation from 1519 to 1522 and said that it was much more calm than the Atlantic.
The andesite line
is the most significant regional distinction in the Pacific. It separates the deeper, mafic
igneous rock
of the Central Pacific Basin from the partially submerged continental areas of felsic
igneous rock on its margins. The andesite line follows the western edge of the islands off California
and passes south of the Aleutian arc, along the eastern edge of the Kamchatka Peninsula
, the Kuril Islands
, Japan
, the Mariana Islands
, the Solomon Islands
, and New Zealand
's North Island
.
The dissimilarity continues northeastward along the western edge of the Andes
Cordillera along South America
to Mexico
, returning then to the islands off California. Indonesia
, the Philippines, Japan, New Guinea, and New Zealand lie outside the Andesite Line.
Within the closed loop of the Andesite Line are most of the deep troughs, submerged volcanic mountains, and oceanic volcanic islands that characterize the Pacific basin. Here basaltic lavas gently flow out of rifts to build huge dome-shaped volcanic mountains whose eroded summits form island arcs, chains, and clusters. Outside the Andesite Line, volcanism is of the explosive type, and the Pacific Ring of Fire
is the world's foremost belt of explosive volcanism
. The Ring of Fire is named after the several hundred active volcanoes that sit above the various subduction zones.
The Pacific Ocean is the only ocean which is almost totally bounded by subduction
zones. Only the Antarctic and Australian coasts have no nearby subduction zones.
. There is no firm date for when the changeover occurred, as the replacement of the sea bed is a continuous process, though reconstruction maps often change the name from Panthalassic to Pacific around the time the Atlantic Ocean
began to open. The Panthalassic Ocean first opened 750 million years ago at the breakup of Rodinia
, but the oldest Pacific Ocean floor is only around 180 Ma old.

— the second largest island in the world. Almost all of the smaller islands of the Pacific lie between 30°N
and 30°S
, extending from Southeast Asia
to Easter Island
; the rest of the Pacific Basin is almost entirely submerged. During the Last glacial period, New Guinea was part of Australia so the largest landmass would have been Borneo

, Marquesas Islands
, Samoa
, Society

, Tuamotu
, Tuvalu
and the Wallis and Futuna
islands.
North of the equator and west of the International Date Line
are the numerous small islands of Micronesia
, including the Caroline Islands
, the Marshall Islands
and the Mariana Islands
.
In the southwestern corner of the Pacific lie the islands of Melanesia
, dominated by New Guinea. Other important island groups of Melanesia include the Bismarck Archipelago
, Fiji
, New Caledonia
, the Solomon Islands
and Vanuatu
.
Islands in the Pacific Ocean are of four basic types: continental islands, high islands, coral reefs, and uplifted coral platforms. Continental islands lie outside the Andesite line
and include New Guinea, the islands of New Zealand, and the Philippines
. Some of these islands are structurally associated with nearby continents. High islands are of volcanic origin, and many contain active volcanoes. Among these are Bougainville
, Hawaii, and the Solomon Islands.
The third and fourth types of islands are both the result of coralline island building. Coral reefs are low-lying structures that have built up on basaltic lava flows under the ocean's surface. One of the most dramatic is the Great Barrier Reef
off northeastern Australia
. A second island type formed of coral is the uplifted coral platform, which is usually slightly larger than the low coral islands. Examples include Banaba
(formerly Ocean Island) and Makatea
in the Tuamotu group of French Polynesia
.
Important human migrations occurred in the Pacific in prehistoric times, most notably those of the Polynesia
ns from the Asian edge of the ocean to Tahiti
and then to Hawaii
, New Zealand
, and Easter Island
.
The ocean was first sighted by Europeans early in the 16th century. Spanish explorer Vasco Núñez de Balboa
crossed the Isthmus of Panama
and reached the Pacific Ocean in 1513, naming it Mar del Sur (South Sea). Later, Portuguese explorer Ferdinand Magellan
sailed the Pacific on a Spanish expedition of world circumnavigation
from 1519 to 1521. Magellan called the ocean Pacífico or "Pacific" because he encountered calm seas throughout his journey. Although Magellan himself died in the Philippines
in 1521, Spanish navigator Juan Sebastian Elcano
led the expedition back to Spain across the Indian Ocean
and round the Cape of Good Hope
, completing the first world circumnavigation in 1522.
In 1564, Spanish explorers crossed the ocean from Mexico led by Miguel López de Legazpi
who sailed to the Philippines
and Mariana Islands
. For the remainder of the 16th century, Spanish influence was paramount, with ships sailing from Mexico
and Peru
across the Pacific Ocean to the Philippines, via Guam
, and establishing the Spanish East Indies
. The Manila Galleon
s operated for two and a half centuries linking Manila
and Acapulco
, in one of the longest trade routes in history. Spanish expeditions also discovered Tuvalu
, the Marquesas
, the Solomon Islands
and New Guinea
in the South Pacific.
Later, in the quest for Terra Australis
, Spanish explorers in the 17th century also discovered the Pitcairn
and Vanuatu
archipelagos, and sailed the Torres Strait
between Australia
and New Guinea, named after navigator Luis Vaz de Torres
. Dutch explorers, sailing around southern Africa, also engaged in discovery and trade; Abel Janszoon Tasman
discovered Tasmania
and New Zealand
in 1642. The 18th century marked the beginning of major exploration by the Russians in Alaska
and the Aleutian Islands. The Spanish also sent expeditions to the Pacific Northwest reaching Vancouver Island
in southern Canada, and Alaska. The French explored and settled Polynesia
, and the British made three voyages with James Cook
to the South Pacific and Australia
, Hawaii
, and the North American Pacific Northwest
. In 1768 Pierre-Antoine Véron
, a young astronomer
accompanying Louis Antoine de Bougainville
on his voyage of exploration, established the width of the Pacific with precision for the first time in history.

Growing imperialism
during the 19th century resulted in the occupation of much of Oceania by European powers, and later, the United States
and Japan
. Significant contributions to oceanographic knowledge were made by the voyages of HMS Beagle
in the 1830s, with Charles Darwin
aboard; HMS Challenger
during the 1870s; the USS Tuscarora
(1873–76); and the German Gazelle (1874–76).
Although the United States gained control of Guam
and the Philippines
from Spain
in 1898, Japan controlled most of the western Pacific by 1914 and occupied many other islands during World War II
. However, by the end of that war, Japan was defeated and the U.S. Pacific Fleet
was the virtual master of the ocean. Since the end of World War II, many former colonies in the Pacific have become independent state
s.
The exploitation of the Pacific's mineral wealth is hampered by the ocean's great depths. In shallow waters of the continental shelves off the coasts of Australia and New Zealand, petroleum
and natural gas
are extracted, and pearl
s are harvested along the coasts of Australia
, Japan
, Papua New Guinea
, Nicaragua
, Panama
, and the Philippines
, although in sharply declining volume in some cases.
The Pacific's greatest asset is its fish
. The shoreline waters of the continents and the more temperate islands yield herring

Marine pollution is a generic term for the harmful entry into the ocean of chemicals or particles. The biggest culprits are people who use the rivers for disposing of their waste. The rivers then empty into the Ocean, and with it the many chemicals used as fertilizer
s in agriculture. The excess of oxygen depleting chemicals in the water leads to hypoxia
and the creation of a dead zone
.
Marine debris
, also known as marine litter, is a term used to describe human-created waste that has found itself floating in a lake, sea, ocean or waterway. Oceanic debris tends to accumulate at the centre of gyres and coastlines, frequently washing aground where it is known as beach litter.
