Geographical position:

It is bounded by the east coast of Eurasia of Australia, the west coast of Northern and South America, the Arctic Ocean in the north, Antarctica in the south.
The Pacific Ocean is usually divided into northern and southern regions, the border of which runs along the equator line.

  • Volume 710.36 million km³
  • Average depth: 4,282 m.
  • Greatest depth: 11022 m (Marian Trench).
  • Salinity: 30-36.5‰.
  • along the 180th meridian Pacific Ocean passes the date line.
• Exercise:
  • Determine the length of the ocean from north to south along the 180 meridian in degrees?
  • Determine the length of the ocean at the equator using a scale.

The name "Quiet" is associated with the name of F. Magellan

For the first time it was crossed by Ferdinand Magellan in 1519, the ocean was called "Pacific", because for all three months of the journey Magellan's ships did not fall into a single storm.
Pacific Ocean in different time had several names:

• Southern Ocean or South Sea (MardelSur) - as it was called by the Indians, the indigenous people Central America, and this name was adopted by the Spanish conquistador Balboa, the first European to see the ocean in 1513. Today Southern Ocean called the waters around Antarctica.
• Great Ocean - named by the French geographer Buachem in 1753. The most correct, but not accustomed name.
• Eastern Ocean - sometimes called in Russia.

The ocean floor is dotted with pits, crevices, trenches, the depth of which is much higher than the average. In the northern latitudes there are such trenches as the North Aleutian and Kuril-Kamchatsky. In the east: Peruvian and Central American. In the west, there are two huge trenches - the Mariana and the Philippine.

Natural features of the ocean.

Two huge rings of water movement are formed in the ocean: northern and southern. The northern ring includes the North Trade Wind Current, the Kuroshio Current, the North Pacific Current and the California Current, while the southern ring includes the South Trade Wind Current, the East Australian Current, the West Wind Current and the Peruvian Current. Question to the class: What is affected by ocean currents?

The world's oceans The ocean is not just a body of water, it is full of life, sometimes much more diverse than the land. In total, there are five oceans on earth: the Atlantic, Pacific, Arctic, South Arctic and Indian. Scientists estimate the number of inhabitants of the ocean as more than two hundred thousand diverse organisms. The permanent inhabitants of the ocean waters, in addition to a variety of fish, are crustaceans, cetaceans, turtles, cephalopods (squids, octopuses, etc.), benthos and plankton. The ocean is not just a body of water, it is saturated with life, sometimes much more diverse than the land.

Seaweeds Seaweeds are ancient, stratified spore plants containing chlorophyll in their cells and living mainly in water. Such a definition, however, does not give an idea of ​​the enormous diversity in body structure that is characteristic of seaweeds. Here we meet with unicellular and multicellular, and with large forms of various structures. There is great diversity in the methods of reproduction. Even in color, seaweeds are not the same, since some contain only chlorophyll, others still have a number of additional pigments that color them in different colors.

Corals Coral is the skeletal material of a colony of coral polyps (“bioherms”). Large accumulations of coral form coral reefs and coral islands. The color of corals depends on the composition and amount of organic compounds: there are not only pink, but also red, blue, white and even black corals. Red corals are called "blood foam", "flower of blood", black - "royal corals". Pink, red and black corals are considered the most valuable.

Whales Whales marine mammals from the order of cetaceans, not related to either dolphins or porpoises. Orcas ("killer whales") and pilot whales have the word "whale" in their informal names, although they are strictly classified as dolphins. Whales switched to an aquatic lifestyle about 50 million years ago. Cetaceans are divided into two suborders: Whales are marine mammals from the order of cetaceans that do not belong to either dolphins or porpoises. Orcas ("killer whales") and pilot whales have the word "whale" in their informal names, although they are strictly classified as dolphins. Whales switched to an aquatic lifestyle about 50 million years ago. Cetaceans are divided into two suborders: Baleen whales, distinguished by their whiskers, a filter-like structure located on the upper jaw, consisting mainly of keratin. The mustache is used to filter plankton from the water. Baleen whales are the largest suborder of whales. Baleen whales, distinguished by their baleen, a filter-like structure located on the upper jaw, composed mainly of keratin. The mustache is used to filter plankton from the water. Baleen whales are the largest suborder of whales. Toothed whales have teeth and prey on fish and squid. The remarkable ability of this group is the ability to feel them. environment using echolocation. Toothed whales have teeth and prey on fish and squid. The remarkable ability of this group is the ability to sense their environment through echolocation.

Dolphins Dolphins are characterized by the presence of relatively small muzzles; body small muzzle; the body is elongated; has a dorsal fin. elongated; has a dorsal fin. Very agile and agile, Very agile and dexterous, voracious predators, living mostly socially; found in all seas. voracious predators, living mostly socially; found in all seas. Feeds mainly Feeds mainly on fish, mollusks, fish, mollusks, crustaceans; sometimes crustaceans; sometimes they attack their relatives. They are also distinguished by curiosity and traditionally a good attitude towards a person.

Crabs The head of the crabs is small, the short abdomen is symmetrical and bent under the jaw and chest. They live in the seas, fresh waters and on land. Sometimes photos reach huge sizes. The giant crab, caught off the coast of Japan, had a distance between the ends of the claws of 3.69 m. There are over 6780 species in the world.

sharks superorder sharks cartilaginous fish, including eight orders, twenty families and Sharks superorder of cartilaginous fish, including eight orders, twenty families and about 350 species. Representatives of the superorder are widespread in all seas and about 350 species. Representatives of the superorder are widespread in all seas and oceans; freshwater sharks are also found. In most oceans, freshwater sharks are also found. Most species belong to the so-called true predators, species belong to the so-called true predators, certain types, in particular the whale, giant and individual species, in particular the whale, giant and largemouth sharks, feed on plankton. Largemouth sharks feed on plankton.

In the waters of the Pacific Ocean is concentrated more than half of the living matter of the entire oceans Earth. This applies to both plants and animals.

For the fauna, totaling up to 100 thousand species: sperm whales, striped whales. seals (sea lions), northern seals; rich fauna fish (from 2000 in warm areas to 800 in cold ones), corals, plankton - 380 species
