What does this mysterious invisible beast that could bring down life as we know it actually do? It's easy to forget that we are all connected by one enormous interconnected body of water. And the AMOC helps make sure our oceans remain as one, like a sort of giant mixing bowl. It moves water, heat, nutrients, dissolved gases and microscopic life around Earth through ocean currents.

The AMOC is a brilliantly complicated system of those ocean currents and eddies, which are circular currents of water. It forms a glorious, giant vertical loop that spans the entire length of the Atlantic Ocean, and it would look like a giant piece of spaghetti just draped across the map. And it's those currents which are pretty interesting here, because there's a few different types of them.

Tidal currents occur close to shore and are influenced by the sun and the moon. Surface currents, which are influenced by the wind, are much slower currents that occur from the surface to the sea floor. They're driven by changes in the saltiness and ocean temperature. Those last ones are the one we're most interested in here. This process is called thermohaline circulation.

Thermo meaning temperature and haline meaning saltiness. The AMOC is part of this thermohaline circulation conveyor belt, circulating water from north to south and back again in a long cycle within the Atlantic Ocean. It drives warm water northwards along the ocean surface and cold, deep waters back southwards.

In doing this, it delivers heat and nutrients to the colder latitudes and also transfers carbon to the ocean depths. Things begin off the east coast of North America, where the Gulf Stream, which is part of the AMOC, carries warm water from the Florida Straits up to the Grand Banks of Newfoundland.

Now, from there, the North Atlantic current then travels across the ocean towards Europe and the Norwegian Sea. When this warmer water reaches the subpolar regions nearer Greenland or Arctica, Not only does it cool down as it loses heat to the atmosphere, but it also becomes more dense. The cooling forms sea ice, and as the ice forms, salt is left behind in the ocean water.

Now that large amount of salt makes the water much denser, causing it to sink down into the ocean at a depth of 2,000 to 3,000 meters, where it's then carried back southwards. That's where the overturning in AMOC comes from.
