The Atlantic meridional overturning circulation (AMOC) is the "main current system in the South and North Atlantic Oceans".[1]: 2238 It is a component of Earth's oceanic circulation system and plays an important role in the climate system. The AMOC includes currents at the surface as well as at great depths in the Atlantic Ocean. These currents are driven by changes in the atmospheric weather as well as by changes in temperature and salinity. They collectively make up one half of the global thermohaline circulation that encompasses the flow of major ocean currents. The other half is the Southern Ocean overturning circulation.[2]
The AMOC is characterized by a northward flow of warmer, fresher water in the upper layers of the Atlantic, and a southward flow of colder, saltier and deeper waters. These limbs are linked by regions of overturning in the Nordic Seas and the Southern Ocean. Overturning sites are associated with the intense exchange of heat, dissolved oxygen, carbon and other nutrients. They are very important for the ocean's ecosystems and for its functioning as a carbon sink.[3][4] Thus, if the strength of the AMOC changes, multiple elements of the climate system would be affected.[1]: 2238
