Characteristics of the Pacific. Rivers and seas of the Pacific Ocean. Ecological state of the ocean

The characteristic of the Pacific indicates thathe is the biggest and deepest on the planet. It washes such continents as Eurasia, America, Australia and Antarctica. In the Mariana Trench, the depth of the ocean reaches 11 km.

Etymology

The first person living in Europe whovisited the eastern side of the ocean, was Balboa, the Spanish conquistador. When he overcame the Isthmus of Panama and, without knowing it, got into the ocean, he called it the South Sea. A few years later, Fernan Magellan decided to try his luck. He traveled for almost four months, breaking the ocean from the Philippines to Tierra del Fuego. After that he was called Silent. But the French scientist Buash, who swam with his team and the Pacific Ocean, and his entire pool, assessing the gigantic size, called it Great. However, this hydronym did not catch on.

Salinity and water properties in winter

Basically the highest saltreaches 35.6%. A similar option is found only in the tropics due to the fact that the climate in these areas is not peculiar to a large amount of precipitation, but here you can observe intense evaporation. The characteristic of the Pacific Ocean, which is in many reference books, indicates that the salinity decreases much closer to the eastern part of the waters due to the cold currents. It must be said that in moderate as well as subpolar zones, this indicator is nearing its minimum level due to constant rain and snow.

The occurrence of ice, that is, the freezing of water,directly depends on the salt content. Often they cover only the Antarctic regions, as well as the waters of the Bering, Japan, and Okhotsk seas. On the shores of Alaska icebergs often occur, which mostly “travel” around the Pacific Ocean.

Ecology

Due to the impact of destructive activityThe human map of the Pacific Ocean makes it possible to mark several zones of waters that are completely polluted and cause great harm to people, and also threaten the life of such species as seals and whales. The main pollution - oil and all types of waste. Because of them, the ocean is overloaded with metals, radioactive substances, which simply should not be in the water. A complete description of the Pacific Ocean showed that all substances falling into it are spread throughout its entire water area. The most interesting thing is that even in the body of animals living near Antarctica, found similar compounds.

Место, которое так и привлекает туристов, уже for a long time does not look like picturesque landscapes. Most people come to look at the garbage stain that formed a few years ago because of the waste that is brought by the currents. What is terrible is that it almost reaches the shores of California, Hawaii and Japan. If for 2001 the area of ​​the spot was 1 billion square meters. km, and weight - 4 million tons, at the moment this figure has increased several thousand times! Every 10 years, this landfill grows to a decent size.

ecological catastrophy

Due to the fact that some birds takesmall plastic flocks for food, they eat them themselves or feed them to the chicks. As a result, these substances are not digested by the body, and the creature dies due to the impossibility of their withdrawal.

Animal and plant life

More than half of the inhabitants of the oceans live inthe waters of the Pacific. Here are many species of fish and plants. Only phytoplankton is located here more than 1300 representatives. The vegetation of waters includes 4 thousand aquatic and 29 land plants. In cold zones, kelp is common, sometimes reaching 200 m in length. In tropical zones, red and fucus algae are found.

There are holothurians who feed on the depths.only ground. Tropical ocean waters are richer in fish several thousand times, unlike other waters. Here you can see sea urchins, horseshoe crabs, as well as several other animal species that are not preserved in other oceans. Most salmon lives right here.

Pacific Rivers

All water streams that flow into the ocean are notdiffer in huge size, but have a fairly large flow rate. At the moment there is no exact number, how many streams merge with these powerful waters. Some have more than 100 watercourses, while others have more than a thousand.

The map of the Pacific Ocean makes it possible to discern 40 rivers that directly belong to its basin. The largest of them is a watercourse, the mouth of which is the Sea of ​​Okhotsk, - Amur.

Minerals

Нельзя упустить тот факт, что дно Тихого океана contains many minerals. There you can find deposits of various minerals. In the shelves of many countries, especially such as Japan, the United States of America, Australia and others, extract gas and oil. Tin in large quantities is mined in Malaysia, zircon - in Australia. Ores and manganese deposits are located in the northern part of the waters. Thanks to the estimates that the characteristics of the Pacific Ocean contain, it can be said for sure that these waters hide about 40% of the reserves of gas and oil. Here are the hydrates, because of which in 2013 in Japan, it was decided to drill wells for the production of natural gas in the direction from the capital of the country to the northeast ocean.

pacific seas

The seas of the Pacific Ocean rarely show theircharacter restless over. At the same time, it is interesting that while traveling on the waters, Magellan and his team did not hit a single storm in all three months of their stay here. That is why the ocean and received such a name. It is divided into several sides: the north and south, the boundary between which passes along the line of the equator.
