As you know, about 70% of our entire planet is covered with water. The largest volume is occupied by the largest body of water - the Pacific Ocean. Geographical position its quite interesting. Let's take a closer look at it further.

Pacific Ocean: geographical location

The Pacific Ocean is considered the most unique natural object our planet due to its characteristics and size. How is the Pacific Ocean geographically different? It is located in all hemispheres of our planet:

In the west - between Australia and Eurasia.

In the east - between South and North America.

In the south it washes Antarctica.

The size of the Pacific Ocean makes up a third of the entire surface of the Earth. It occupies half of the world's oceans.

External description

The Pacific Ocean has oval elongated coastlines from northwest to southeast and wide outlines in tropical zones. The straightness of the coast can be seen near the American coast, and the dissected nature of the Eurasian landmass.

The largest ocean includes the marginal seas of Asia. The waters of the Pacific harbor a large number of islands and archipelagos.

Scale

Descriptions of the geographical location of the Pacific Ocean always traditionally begin with its scale. To be precise, Pacifica waters occupy 49.5% of the planet’s water surface, which means it contains 53% of the total volume of water. From west to east, the water surface stretches for 19 thousand km, and from north to south - more than 16 thousand. Most ocean waters are located in southern latitudes, and a minority are located in the northern part of the Earth.

Story

The Pacific Ocean is interesting for its history. For a long time, the geographical position at all latitudes did not allow scientists to check where the deepest place of Pacifica is located.

In 1951, an expedition of British scientific researchers on the Challenger vessel calculated the maximum depth of the Pacific Ocean. According to calculations made using an echo sounder, it was 10,863 meters. But after 6 years, these data were refuted by a Soviet group of scientists. The research ship Vityaz, led by Alexander Dmitrievich Dobrovolsky, recorded the maximum depth of the Challenger Deep depression at 11,034 meters. Today the correct figure is 10,994 meters, adjusted by +/- 40 meters.

What is the geographical location of the Pacific Ocean?

The difference between the Pacific and other oceans is obvious. The Pacific Ocean, whose geographical location is very wide, borders the Arctic Ocean, where the Bering Strait acts as a border. The border with the Atlantic Ocean is visible from Cape Horn (68°04'W) to the Antarctic Peninsula. Geographical location of the Pacific and Indian Oceansalso intersects. The border of the two bodies of water runs north of Australia - between the Strait of Malacca and the Andaman Sea; along the southern shore of the island. Sumatra and o. Java, between the boundaries of the Savu and Bali seas to the western part of the Arafura Sea.

The Pacific Ocean, whose geographical location is so interesting, is recognizable by the circulation of the atmosphere and water and by the nature of the topography of its bottom.

Seas

The bays, straits and seas of the Pacific Ocean cover almost 32 million square meters. km, which is 18% of its total area. Most of the seas are concentrated in its western part, off the Eurasian coasts: Japanese, Okhotsk, Yellow, Philippine, Bering, East China. Many Pacific seas wash the shores of Australia: Solomonovo, Fiji, Coral, New Guinea, Tasmanovo. Cold Antarctica also has seas that are subordinate to the Pacific Ocean: Ross, Amundsen, D'Urville, Somov, Bellingshausen. The coasts of South and North America do not have seas, but they are washed by the Pacific Gulfs: Panama, Alaska, and California.

Pacific Ocean: geographical location of the islands

The Pacific is rich in islands, and in this competition it has no equal among other oceans. Several thousand small areas of land in Oceania were formed due to volcanic eruptions. Many of them became overgrown with corals, after which they sank into the water, leaving behind atolls and reefs. The Pacific Ocean is home to several of the world's largest islands: Kalimantan and New Guinea. There are also islands in Asia large sizes: Kuril Islands, Sakhalin, Commander Islands, Japanese, Philippine, Sunda, Hainan, Taiwan and others. In Antarctica there are the Shetland Islands and the Land of Alexander the Great, the Palmer Archipelago. Off the coast of South and North America - the Aleutian, Vancouver, Tierra del Fuego, Queen Charlotte Islands and others.

Mysterious Ocean

The world's oceans contain the waters of four oceans. But only one of them exists in all latitudes of the world at once, and his name is Quiet. Its scale, size, depth and the presence of seas, archipelagos, and islands make the expanse of water mysterious and special. The ocean depths hide many secrets that we have yet to learn about...

PACIFIC OCEAN: GEOGRAPHICAL POSITION

The Great, or Pacific, Ocean - greatest Earth's ocean. It accounts for about half (49%) of the area and more than half (53%) of the volume of the waters of the World Ocean, and its surface area is equal to almost a third of the entire surface of the Earth as a whole. In terms of the number (about 10 thousand) and total area (more than 3.5 million km 2) of islands, it ranks first among the other oceans of the Earth.

In the northwest and west the Pacific Ocean limited the shores of Eurasia and Australia, in the northeast and east - the shores of the Northern and South America. The border with the Arctic Ocean is drawn through the Bering Strait along the Arctic Circle. The southern border of the Pacific Ocean (as well as the Atlantic and Indian) is considered to be the northern coast of Antarctica. When distinguishing the Southern (Antarctic) Ocean, its northern boundary is drawn along the waters of the World Ocean, depending on the change in the regime of surface waters from temperate latitudes to Antarctic latitudes. It runs approximately between 48 and 60° S. ( rice. 3).

Rice. 3. Ocean boundaries

The boundaries with other oceans south of Australia and South America are also drawn conditionally along the water surface: with the Indian Ocean - from Cape South East Point at approximately 147° E, with the Atlantic Ocean - from Cape Horn to the Antarctic Peninsula. In addition to wide connections with other oceans in the south, there is communication between the Pacific and northern Indian Oceans through the interisland seas and the straits of the Sunda archipelago.

Square The Pacific Ocean from the Bering Strait to the shores of Antarctica is 178 million km 2, the volume of water is 710 million km 3.

Northern and western (Eurasian) shores of the Pacific Ocean dismembered seas (there are more than 20 of them), bays and straits separating large peninsulas, islands and entire archipelagos of continental and volcanic origin. The coasts of Eastern Australia, southern North America, and especially South America are generally straightforward and inaccessible from the ocean. With a huge surface area and linear dimensions (more than 19 thousand km from west to east and about 16 thousand km from north to south), the Pacific Ocean is characterized by weak development of the continental margins (only 10% of the bottom area) and a relatively small number of shelf seas.

Within the intertropical space, the Pacific Ocean is characterized by clusters of volcanic and coral islands.

Within the intertropical space, the Pacific Ocean is characterized by clusters of volcanic and coral islands.

Ocean floor, mid-ocean ridges and transition zones

There are still different points of view on the question of the time of formation of the Pacific Ocean in its modern form, but, obviously, by the end of the Paleozoic era, a vast body of water already existed in the place of its basin, as well as the ancient continent of Pangea, located approximately symmetrically with respect to the equator . At the same time, the formation of the future Tethys Ocean began in the form of a huge bay, the development of which and the invasion of Pangea subsequently led to its disintegration and the formation of modern continents and oceans.

The bed of the modern Pacific Ocean is formed by a system of lithospheric plates, bounded on the ocean side by mid-ocean ridges, which are part of the global system of mid-ocean ridges of the World Ocean. These are the East Pacific Rise and the South Pacific Ridge, which, reaching a width of up to 2 thousand km in places, connect with each other in the southern part of the ocean and continue westward into the Indian Ocean. The East Pacific Ridge, extending northeast to the coast of North America, in the Gulf of California region, connects with the system of continental rift faults of the California Valley, the Yosemite Trench and the San Andreas Fault. The middle ridges of the Pacific Ocean themselves, unlike the ridges of other oceans, do not have a clearly defined axial rift zone, but are characterized by intense seismicity and volcanism with a predominance of emissions of ultrabasic rocks, i.e., they have the features of a zone of intensive renewal of the oceanic lithosphere. Throughout the entire length, the middle ridges and adjacent plate sections are intersected by deep transverse faults, which are also characterized by the development of modern and, especially, ancient intraplate volcanism. Located between the median ridges and limited by deep-sea trenches and transition zones, the vast floor of the Pacific Ocean has a complexly dissected surface, consisting of a large number of basins with a depth of 5000 to 7000 m or more, the bottom of which is composed of oceanic crust covered with deep-sea clays, limestones and silts of organic origin. . The bottom topography of the basins is mostly hilly. The deepest basins (about 7000 m or more): Central, Western Mariana, Philippine, Southern, Northeastern, East Carolinian.

The basins are separated from each other or crossed by arched rises or blocky ridges on which volcanic structures are planted, within the intertropical space often crowned with coral structures. Their tops protrude above the water in the form of small islands, often grouped into linearly elongated archipelagos. Some of them are still active volcanoes, spewing streams of basaltic lava. But for the most part these are already extinct volcanoes, built on with coral reefs. Some of these volcanic mountains are located at a depth of 200 to 2000 m. Their peaks are leveled by abrasion; the position deep under water is obviously associated with the lowering of the bottom. Formations of this type are called guyots.

Of particular interest among the archipelagos of the central Pacific Ocean are the Hawaiian Islands. They form a chain 2,500 km long, stretching north and south of the Tropic of the North, and are the tops of huge volcanic massifs rising from the ocean floor along a powerful deep fault. Their apparent height is from 1000 to 4200 m, and their underwater height is approximately 5000 m. According to their origin, internal structure and appearance Hawaiian Islands -- typical example oceanic intraplate volcanism.

The Hawaiian Islands are the northern edge of a huge central Pacific island group collectively known as Polynesia. The continuation of this group to approximately 10° S. are the islands of Central and Southern Polynesia (Samoa, Cook, Society, Tabuai, Marquesas, etc.). These archipelagos, as a rule, extend from northwest to southeast, along transform fault lines. Most of them are of volcanic origin and are composed of strata of basaltic lava. Some are topped with wide and gently sloping volcanic cones 1000-2000 m high. The smallest islands in most cases are coral structures. Similar features have numerous clusters of small islands located mainly north of the equator, in the western part of the Pacific lithospheric plate: the Mariana, Caroline, Marshall and Palau Islands, as well as the Gilbert Archipelago, which partially extends into the southern hemisphere. These groups of small islands are collectively called Micronesia. All of them are of coral or volcanic origin, mountainous and rise hundreds of meters above sea level. The coasts are surrounded by surface and underwater coral reefs, making navigation very difficult. Many small islands are atolls. Near some islands there are deep-sea ocean trenches, and to the west of the Mariana Archipelago there is a deep-sea trench of the same name, belonging to the transition zone between the ocean and the Eurasian continent.

In the part of the Pacific Ocean bed adjacent to the American continents, small single volcanic islands are usually scattered: Juan Fernandez, Cocos, Easter, etc. The largest and most interesting group are the Galapagos Islands, located near the equator near the coast of South America. This is an archipelago of 16 large and many small volcanic islands with the peaks of extinct and active volcanoes up to 1700 m high.

Transition zones from the ocean to the continents differ in the structure of the ocean floor and the characteristics of tectonic processes both in the geological past and at the present time. They surround the Pacific Ocean in the west, north and east. In different parts of the ocean, the processes of formation of these zones proceed differently and lead to different results, but everywhere they are distinguished by great activity both in the geological past and at the present time.

On the side of the ocean floor, transition zones are limited by arcs of deep-sea trenches, in the direction of which lithospheric plates move and the oceanic lithosphere subsides under the continents. Within the transition zones, the structure of the ocean floor and marginal seas is dominated by transitional types of the earth's crust, and oceanic types of volcanism are replaced by mixed effusive-explosive volcanism of subduction zones. Here we are talking about the so-called “Pacific Ring of Fire,” which encircles the Pacific Ocean and is characterized by high seismicity, numerous manifestations of paleovolcanism and volcanogenic landforms, as well as the existence within its boundaries of more than 75% of the planet’s currently active volcanoes. This is mainly mixed effusive-explosive volcanism of intermediate composition.

Most brightly everything typical features The transition zone is expressed within the northern and western margins of the Pacific Ocean, that is, off the coast of Alaska, Eurasia and Australia. This wide strip between the ocean bed and the land, including the underwater margins of the continents, is unique in terms of the complexity of its structure and the relationship between the land and the water area; it is distinguished by significant fluctuations in depths and heights, and the intensity of processes occurring both deep in the earth’s crust and on the water surface.

The outer edge of the transition zone in the north Pacific Ocean is formed by the Aleutian deep-sea trench, extending 4000 km in a convex arc to the south from the Gulf of Alaska to the shores of the Kamchatka Peninsula, with a maximum depth of 7855 m. This trench, towards which the movement of lithospheric plates of the northern part of the Pacific Ocean is directed, from the rear it borders the underwater foot of the Aleutian island chain, most of them are volcanoes of the explosive-effusive type. About 25 of them are active.

A continuation of this zone off the coast of Eurasia is a system of deep-sea trenches, with which are connected the deepest parts of the World Ocean and, at the same time, areas of the most complete and diverse manifestation of volcanism, both ancient and modern, both on island arcs and on the outskirts of the continent. In the rear of the Kuril-Kamchatka deep-sea trench (maximum depth over 9700 m) there is the Kamchatka Peninsula with its 160 volcanoes, of which 28 are active, and the arc of the volcanic Kuril Islands with 40 active volcanoes. The Kuril Islands are the peaks of an underwater mountain range that rises above the bottom of the Sea of ​​Okhotsk by 2000-3000 m, and the maximum depth of the Kuril-Kamchatka Trench, which runs from the Pacific Ocean, exceeds 10,500 m.

The system of deep-sea trenches continues to the south with the Japan Trench, and the volcanogenic zone continues with the extinct and active volcanoes of the Japanese Islands. The entire system of trenches, as well as island arcs, starting from the Kamchatka Peninsula, separates the shallow shelf Seas of Okhotsk and East China from the Eurasian continent, as well as the Sea of ​​Japan depression located between them with a maximum depth of 3720 m.

Near the southern part of the Japanese Islands, the transition zone expands and becomes more complex, the strip of deep-sea trenches is divided into two branches, bordering on both sides the vast Philippine Sea, the depression of which has a complex structure and a maximum depth of more than 7000 m. From the Pacific Ocean it is limited by the Mariana Trench with its maximum depth World ocean 11,022 m and the arc of the Mariana Islands. The internal branch, limiting the Philippine Sea from the west, is formed by the trench and the Ryukyu Islands and continues further with the Philippine trench and the arc of the Philippine Islands. The Philippine Trench stretches along the foot of the islands of the same name for more than 1,300 km and has a maximum depth of 10,265 m. There are ten active and many extinct volcanoes on the islands. Between the island arcs and Southeast Asia, within the continental shelf, lie the East China Sea and most of the South China Sea (the largest in the region). Only the eastern part of the South China Sea and the interisland seas of the Malay Archipelago reach depths of over 5000 m, and their base is a transitional crust.

Along the equator, the transition zone within the Sunda archipelago and its island seas continues towards the Indian Ocean. There are a total of 500 volcanoes on the Indonesian islands, of which 170 are active.

The southern region of the Pacific Ocean transition zone northeast of Australia is particularly complex. It extends from Kalimantan to New Guinea and further south to 20° S, bordering the Sokhul-Queensland shelf of Australia to the north. This entire section of the transition zone is a complex combination of deep-sea trenches with depths of 6000 m or more, submarine ridges and island arcs, separated by basins or areas of shallow water.

Off the eastern coast of Australia, between New Guinea and New Caledonia, is the Coral Sea. From the east it is limited by a system of deep-sea trenches and island arcs (New Hebrides, etc.). The depths of the Coral basin and other seas of this transitional region (the Fiji Sea and especially the Tasman Sea) reach 5000-9000 m, their bottom is composed of oceanic or transitional type crust.

The hydrological regime of the northern part of this area favors the development of corals, which are especially common in the Coral Sea. On the Australian side, it is limited by a unique natural structure - the Great Barrier Reef, which stretches along the continental shelf for 2,300 km and reaches a width of 150 km in the southern part. It consists of individual islands and entire archipelagos, made of coral limestone and surrounded by underwater reefs of living and dead coral polyps. Narrow channels crossing the Great Barrier Reef lead to the so-called Great Lagoon, the depth of which does not exceed 50 m.

From the side of the Southern Basin of the ocean floor between the islands of Fiji and Samoa, the second arc of trenches, external to the ocean, extends to the southwest: Tonga (its depth of 10,882 m is the maximum depth of the World Ocean in the southern hemisphere) and its continuation Kermadec, maximum depth which also exceeds 10 thousand m. On the Fiji sea side, the Tonga and Kermadec trenches are limited by underwater ridges and arcs of the islands of the same name. In total, they stretch 2000 km to the North Island of New Zealand. The archipelago rises above the underwater plateau that serves as its pedestal. This is a special type of structure of the underwater margins of continents and transition zones, called microcontinents. They vary in size and are uplifts composed of continental crust, topped with islands and surrounded on all sides by basins with oceanic-type crust within the World Ocean.

The transition zone of the eastern part of the Pacific Ocean, facing the continents of North and South America, differs significantly from its western margin. There are no marginal seas or island arcs. A strip of narrow shelf with mainland islands stretches from the south of Alaska to Central America. Along the western coast of Central America, as well as from the equator along the outskirts of South America, there is a system of deep-sea trenches - Central American, Peruvian and Chilean (Atacama) with maximum depths of more than 6000 and 8000 m, respectively. Obviously, the process of formation of this part of the ocean and neighboring continents took place during the interaction of deep-sea trenches that existed at that time and continental lithospheric plates. North America moved onto the trenches along its path to the west and closed them, and the South American Plate moved the Atacama Trench to the west. In both cases, as a result of the interaction of oceanic and continental structures, folding occurred, the marginal parts of both continents were uplifted, and powerful suture zones were formed - the North American Cordillera and the Andes of South America. Each of these structural zones is characterized by intense seismicity and the manifestation of mixed types of volcanism. O.K. Leontiev considered it possible to compare them with the underwater ridges of the island arcs of the western transition zone of the Pacific Ocean.

  Pacific Ocean also called the Great, because it is the largest on the planet. The ocean covers almost the same area as all other oceans combined (Fig. 17). Its area - 178.6 million km 2 - would freely accommodate all the continents and at the same time there would be room for one more Africa.

  Northern Pacific Ocean border conditionally drawn through the Bering Strait from the coast of Eurasia to the coast of North America. In the south, the ocean washes the coast of Australia and reaches the shores of Antarctica. Here its boundaries are drawn conditionally, along the meridians. The Pacific Ocean lies in almost all geographical zones of the Earth, with the exception of the Arctic.

  The central regions of the ocean lie in the equatorial belt, and the equator itself divides the ocean into approximately two equal parts. Therefore, north and south of the equator, the nature of the Pacific Ocean is similar. At the same time, in the western and eastern parts of the same geographical zone, the nature of the ocean is noticeably different (Fig. 18). These differences are due, in particular, to sea currents.

  Differences in nature The western and eastern parts of the ocean are also determined by the outlines of the coastlines of the continents. In Eurasia it is very dissected and has numerous bays, islands and marginal seas. These bays and seas often cut deep into the land. Therefore, the western part of the Pacific Ocean is more influenced by continents than the eastern part.

  The Pacific Ocean washes the coasts of Eurasia, Australia, North and South America. And although they are located at a distance of many thousands of kilometers from each other, the waters of the Pacific Ocean not only separate continents and states, but also connect them. After all, the most important transport routes connecting the countries of Asia, Australia and America lie across the ocean. Material from the site
