What is thermohaline circulation?

Thermohaline circulation is a very slow and extremely deep movement of water in the oceans around the world. The complete cycle may take thousands of years from the beginning to the end, while the cycle contributes to the mixing of the world's oceans. The circulation of thermohaline seems to be associated with global health health and ocean because it mixes melted gases and minerals in water and can also affect global temperatures. These salts are known as halogenides. Temperature and Halinity of water have an impact on its density and it triggers thermohalin circulation. The colder the water, the denser it is and the salty the water, the higher the density. Due to thermohalin circulation, the Atlantic Ocean is denser than Indian and Pacific Oceans, which is slightly lower.

The cycle begins around Rovnyor in the Pacific Ocean, when surface currents like current stream slowly drive water to the west. This water is warm and is not terribly salty, so it is light, so it floats on the surface of the ocean. As water goes to the west, slowly walks into the northern Atlantic where the hairAdí because of the ambient temperatures. In addition, the salinity increases through evaporation.

This combination of factors causes water to slowly drop to the bottom of the ocean. Also, it also slowly begins to move to the south because more sinking water from the surface stream is pushed. Some of the thick cold water settles in the deep ocean basins, but most of it slowly circulate south before moving to the east, around the African corner and back to the place where it was created; Some water slips down Australia to appear in the South Pacific, while the second part of the deep ocean current winds its Way Indian Ocean. As Cycles's water becomes warmer and less salty until it applies in the Pacific just to start the cycle again.

Some people raised concerns about the impact of global warming on thermohallum circulation. There is some concern that increasing the melt of glaciers could reduce the halonite of the ocean in SEver Atlantic, which caused the cycle to turn off. This can lead to localized cooling in the northern hemisphere, which could have serious consequences for organisms that live there.
